Everything You Ever Wanted to Know About Storm and Parking Brakes

Posted on by

Mounting cranes on rails increases their utility in loading/unloading and other material handling tasks. However, it also creates another potential hazard: the risk of uncontrolled movement. Tall cranes used outdoors, especially in coastal regions, are vulnerable to high winds and wind microbursts. Earthquakes are another possible cause of unexpected motion in many locations, and the risk of collision with forklift trucks and similar machinery is ever-present throughout industrial and logistics operations.

Uncontrolled crane movement can be devastating, as is evident in a 2008 video of a crane collapse in Florida. It can disrupt operations, require expensive repairs and even cause loss of life. This is why storm and parking brakes should be considered essential on rail-mounted equipment. Here we explain these, outline how the various types work, and discuss when each should be used.

Rail Clamps and Wheel Brakes

Storm and parking brakes for rail-mounted equipment act either on the rail or on the wheels. The two categories are rail clamps and wheel brakes.

As the name suggests, clamps clamp onto the rail. This makes them appropriate for static situations where they act as parking brakes. In contrast, wheel brakes apply friction to the wheel (usually the idler wheels of cranes.) Thus, while wheel brakes are intended for static use, they can be used as dynamic brakes in emergencies.

Rail clamps come in two forms: clamps that grip onto the sides of the rail and press brakes that push down on the top. Clamp mechanisms usually include rollers that run along the tops of the rails. Retractable systems are available for high-speed cranes where rollers would add additional resistance.

Press brakes use the crane’s weight to lock it in position while clamps rely on spring force (which can exceed 1,000 kN.) Press brakes are used where the rail top is flush with the roadway and inaccessible to side clamps. They also do a better job of accommodating variation in rail height.

Brake Application and Release

Rail clamps, rail press brakes, and wheel brakes are all designed for fail-safe operation. Spring-loaded mechanisms force the clamps or friction material against the rail or wheel. Then, power is applied to pull the clamps off.

With clamps and press brakes, the release is almost always performed by hydraulics. (Some smaller units have electric release mechanisms.) Likewise, wheel brakes are predominantly electric release. However, hydraulic systems are more complex, requiring a pump or pumps plus reservoir, and should be inspected for leaks periodically.

When selecting or specifying storm and parking brakes, remember to consider how they are released in the event of a power failure. Again, the manufacturers or a knowledgeable distributor will be able to advise.

AC vs. DC Motor: What’s the Difference Between Them?

Posted on by

Are you looking for a new motor for an application or piece of construction equipment? Before making any purchases, you must know whether you need to buy an AC motor or a DC motor.

Both types of motors have practical uses in many industries. However, they differ in cost, efficiency, reliability, and performance. By assessing your project requirements, you will know the best motor for you using this guide.

Keep reading to learn about the differences between an AC and a DC motor. 

AC Motor

AC means alternating current. An AC motor uses AC power which reverses the current direction, alternating between positive and negative. 

There are two major types of AC motors — synchronous and induction. 

The synchronous motor rotates at the same rate as the frequency of the supply current. 

The induction motor is the most common type of AC motor. The output rotation is proportional to the applied frequency of the alternate current. Electromagnetic induction creates the electric current that turns the rotor. 

AC motors are robust, durable, and affordable. In addition, they have a longer lifespan and lower repair costs than DC motors.

AC motors are used in large-scale, continuous-speed applications where the motor speed is slow to medium. This is because they are resistant and slow to respond to changes in speed when the load changes. 

AC motors are best for applications that need high speed and variable torque. They tend to lose torque at higher speeds.

DC Motor

On the other hand, a DC motor uses DC power. DC means direct current. The power flows in one direction, like in a battery. As a result, DC motors are usually more efficient than AC motors.

Additionally, they are also more expensive and have high repair costs.

There are also two major types of DC motors — brushed and brushless. 

Brushed motors use a carbon brush to conduct electricity through an internal commutator.

Brushless motors are similar to brushed motors, minus the brushes. Additionally, they have a specialized circuit to control power speed and direction. Furthermore, the motor uses magnets mounted around the rotor to improve efficiency. 

Brushed motors have a shorter life span than brushless motors because of the wear and tear of the brush. But, they have a more straightforward design, so they aren’t as expensive as a brushless motor.

DC motors are quick to respond to a change in the power load. Therefore, they are best for applications that need high torque and variable speed. 

Domestic applications and robotics most often use DC motors because they need fine speed control.

Brief Guide to Oil Rig Equipment

Posted on by

When it comes to operating factories, machines, vehicles, and even homes, the typical fuels used are gas and oil. In 2019, it was estimated that the world held 1,733.9 billion barrels of oil reserves, according to Discover Magazine. Finding this oil requires specialized equipment and exploration work to bring it up to the surface for processing. Oil rig equipment helps to extract the oil and petroleum from the land as well as from the sea.

Technology in the oil equipment industry has evolved for the exploration and drilling of oil to minimize damage to the ecosystem and prevent oil leaks that can harm the environment. From global positioning systems to remote sensing devices, these technologies are designed to help discover the possible location of oil reserves so that fewer exploratory wells are drilled. Check out our brief guide regarding some of the oil rig equipment used in this industry.

Mast

An essential structure on an oil rig is the mast. The mast, also called a derrick, holds and lifts the components used in the drilling operation. It acts as a lifting device for the drill string, such as the drill pipes and other accessories.

Drill String

The drill string refers to all the drill pipes, the bottom hole assembly, and all the other components used in the operation of the drill bit that will tun at the wellbore’s bottom. The drill string comprises the drill pipe, drill collars, drill jars, stabilizers, heavyweight drill pipe, and other tools.

Rotary Table

The rotary table is a section of the drill floor that rotates or spins. It provides power to the drill string and the bit as it moves in a clockwise rotation. The rotary table’s power is transmitted through the kelly bushing, as the entire rig is sometimes called a kelly drive rig. The rotary table may be used for primary power or backup power.

Top Drive

The top drive consists of a motor that is suspended at the top of the mast. The motor turns the drill string as an alternative to the rotary table and may be used in special circumstances. The top drive assists with the bore head drilling process.

Mud Pump

The mud pump is a reciprocating pump that circulates the drilling fluid (drilling mud) downhole along the drilling string and back up to the surface through the annulus, the space between the casing and wellbore or casing and tubing. This fluid circulation is at extremely high pressures.

Shale Shakers

Shale shakers are fluid separation systems that remove the large solids (cuttings) from the drilling fluid. Shale shakers help reduce drilling costs and make operations efficient while ensuring the drilling fluid circulates to keep the drill bit cool.

Many other oil rig technologies and equipment are used—ensuring that the equipment functions correctly and that replacement parts are available in case of breakage, allows an oil rig to function optimally when extracting petroleum and oil from the earth’s depths. Here at Kor-Pak, we offer oil rig equipment. Contact us for more information.

Torque Limiter Maintenance, Repair, and Replacement

Posted on by

Torque limiters are critical elements in rotational machine assemblies that protect against instantaneous overload conditions.

Overloads are often multivariable and caused by both mechanical and electrical factors. Therefore, a torque-limiting switch is implemented to mitigate potential overload damage, regardless of the root cause. Limiters establish a peak value for torque-generated force in a system.

Rotational components operate uninterrupted within the bounds of the set torque limit. When the limit is exceeded, the operating machine is immediately detached from the load. The load separation stops the overload cascade from surging through the system, avoiding potential damage to the machine and its operators.

Proper maintenance and repair scheduling of limiter components should be prioritized in any heavy-duty, high-cycle operation. Machine troubleshooting can be conducted after a power failure, but any resulting damage cannot be undone. Effective use of a torque limiter circumvents much of the risk inherent to equipment failures.

Torque limiters are mostly autonomous but are not immune to malfunction or regular wear and tear. Several operative signals may indicate your torque limiter needs repair or replacement.

1. Abnormal Sounds at Start-Up

A sudden separation from loading elements is not a gentle process. During successful operation, torque limiters generate noise – and this should be expected.

On occasion, a torque-based system may emit a grinding, slamming, screeching, or whirring noise on start-up. These sounds can be accompanied by non-typical rumbling or physical motion in the equipment (as if a component was being tossed around). However, if the system is operating beneath the torque threshold set by the limiter, there should be no rattling, slipping, or squealing from the protective component.

Assess the characteristics of the noise and when it occurs. For example, if there are consistent noises at start-up, the torque limiter may be improperly installed, damaged, or over-slipping.

2. Motor Will Not Turn-Over / Start

Depending on the equipment, the torque limiter may be implicated in no-start conditions.

For example, electric engines that demand maximal torque at start-up – zero revolutions – may trigger immediate slippage by the torque limiter. As a result, the motor will be unable to turn over. A no-start might be accompanied by the sounds noted above, ignition chugging, or another rattling in the equipment.

3. Torque Limiter Slippage

Torque limiters are designed to slip – that’s how they can disengage from the load component. However, a total slippage of the limiter can mean operators will be unable to start or re-engage the equipment. Thus, slippage is undesirable below the set torque threshold. Coincidentally, over-slippage tends to be responsible for many situations involving abnormal noises and no-start motor conditions.

The type of torque limiter affects the mode of slippage. For example, friction plate, magnetic particle, and magnetic hysteresis torque limiters use different slip mechanisms to achieve the same operational goal.

5 Reasons Why You Need an Overhead Crane Inspection

Posted on by

Overhead cranes allow companies to move materials from one location to another with the items suspended in the air. It is commonly used in warehousing and transportation, yet these cranes are also found in mining processing, agricultural manufacturing, and many other industries. Ensuring that your overhead crane functions optimally means that the working mechanisms and supports have undergone proper maintenance and repair. Overhead crane inspections are another essential aspect of properly maintaining your equipment. Find out why you should get your overhead crane inspected.

Reasons to Perform Overhead Crane Inspections

1. Spot Cracks, Deterioration, and Failures

Inspections allow you to spot potential problems before they become serious issues. Overhead cranes work with many moving parts at once. Any part that experiences failure could lead to the entire crane malfunctioning to the point where it can no longer perform tasks. Certain overhead crane features should undergo daily maintenance, such as the hydraulic systems and crane hooks. Other areas can have monthly inspections such as hoist chains, ropes, and end connections. Some inspections may be performed on an as-needed basis.

2. Avoid Costly Part Replacements

Spotting minor problems and immediately placing the overhead crane into service ensures that all components function appropriately. However, holding off on the inspections and required repairs could lead to catastrophic failure to the crane’s systems. When devastating failure occurs, it may lead to replacing entire systems. The cost of replacing systems can be an enormous burden on the company’s finances.

3. Helps to Create Preventive Maintenance Checklist

An inspection provides you with essential details about your overhead crane and how it is used. The inspector may notice specific components and parts that are worn out faster than the manufacturer’s recommendations during the inspection. With this data, you may adjust the preventive maintenance checklist to evaluate these systems and components on a more daily schedule to prevent significant problems.

4. Meet OSHA Requirements

Overhead crane and gantry operations are regulated by the Occupational Safety and Health Administration (OSHA). If the cranes are not inspected and maintained following these guidelines and standards, accidents may cause serious damage and worker injuries. OSHA regulators may penalize a company that has not performed the required inspections and instituted safety measures in compliance with stated guidelines. These fines could be costly for your company,

5. Prevent Worker Injuries

Having a worker become injured due to materials falling from the overhead crane causes significant problems to your company. You must ensure that the working environment is cordoned off to prevent further damage and injuries. Then you have to deal with the worker’s medical bills, worker compensation claims, or even lawsuits. Your operations will also have to remain down until the evaluation of the overhead crane is complete, and they determine why there was a failure. Then you must make repairs before operations begin again.

An overhead crane experiences large stress loads daily. Ensuring that the equipment functions efficiently is essential so that operations keep up with productivity. An overhead crane inspection provides many advantages to your company to keep equipment running and keep repair costs low.

EMG Thruster Maintenance and Repair

Posted on by

The high demand for EMG thruster units often results in low stock across distribution channels. Replacing an electrohydraulic thruster can impair project lead times significantly and introduce a significant cost burden. Adhering to a proper repair and maintenance protocol enables a quicker and more economical turnaround.

Design and Operation

ELDRO and ELHY electrohydraulic thrusters are built with scalable, long-term use in mind. Versatility in a wide range of environmental and project-specific scenarios is prioritized in the design.

Primary design features include:

  • Reliability and long service life
  • Minimized regulating periods – fast response
  • Multipurpose designs may be specified for the environment
  • Operational overload protection
  • Straightforward assembly, disassembly, and installation
  • Multidirectional motor rotation – removing the need for reversing contractor components
  • Switching frequency graded to 2000 cycles per hour
  • Adjustable stroke
  • Modifiable lift and lower times

EMG thrusters are commonly employed industrially in crane, mining, and conveyor machinery. Systems demanding high-duty cycles in harsh operative conditions can stand to benefit from an electrohydraulic thruster unit.

ELDRO

ELDRO thrusters are built according to a coaxial functional assembly comprised of an electric motor and hydraulic unit. Implicit to a hydraulic system, thrust is generated via an appropriate operating fluid modulated by a centrifugal pump. The piston is designed to retract automatically if operational power is lost, and the brake springs will lock into place.

ELHY

ELHY brake thrusters are compact, low-noise units provided in several models bearing the same general structure. A three-phase motor is housed at the base, attached to a terminal box. The hydraulic pump is seated atop the motor, which connects to the piston and rod shaft. The ELHY model is crafted to ensure last-line defense against power failures and operative malfunctions.

Risk Factors

Electrohydraulic thrusters are often subject to extreme conditions. The intentional balancing of a thruster’s internal components and casings requires special awareness on behalf of operator and machine wellbeing.

EMG units are equipped with positional measurement systems and internal level indicators. These mechanisms indicate stroke path, piston rod depth, and release or brake position. In addition, limit switches may be utilized to provide more sophisticated data. Careful monitoring of EMG measurements can give a predictable baseline and point toward equipment fitness.

Corrosion is an active risk for any mechanism operating in high relative humidity or conditions where excessive condensation builds. EMG thrusters are fitted with redundant seals and protective tubing, but increased protection is recommended for intensive circumstances. Operators may consider the use of parking heaters or specialized sealing paint for the housing structure.

Repair and Maintenance Protocol

Kor-Pak offers consultations for use and rapid turnover repair services of EMG thruster units.

Our standard repair process involves complete strip-down disassembly of the electrohydraulic unit. Kor-Pak conducts a thorough visual inspection of each component. Housing, motor, piston, and brake assemblies are evaluated for damage related to corrosion, impact, and excessive wear. Bearings, seals, gaskets, and paint are replaced as part of our service.

Each repaired unit is put through a load and environmental condition check, then certified by Kor-Pak’s specialists.

Crane Conductor Bars and Systems

Posted on by

Overhead crane conductor bars are crucial structures that enable consistent power flow to internal and auxiliary crane functions. Conductor bars are precisely engineered to maximize safety and rates of power delivery.

The diverse operational applications of cranes mean power systems need to be versatile. A capacity for broad adaptation ensures the equipment can account for many different project variables. Therefore, conducting system options are designed with durability, mounting variability, heat dissipation, insulation, and ease of installation held at high priority.

Crane Conductor Bars

Crane conductor bars are constituted by a multi-part system working in unison.

A summary of conductor bar elements:

  • Conductor Bar
  • Collector
  • Hangers
  • Brackets
  • Anchor Clamp
  • End Cover
  • Power Feed

The primary conductor bar supplies and guides power along the crane bridge. A collector unit processes the delivered current and feeds it into the various crane machines. Hangers connect a series of supportive brackets along the runway to the conductor bar itself. An anchor clamp may be implemented to modulate conductor movement during thermal expansions or contractions. The end of the conductor bar is capped by an end cover to provide safety and a cut-off to the flow of electrical current.

Conductors are built for efficiency, ease of installation, and longevity. In addition, they’re compatible with a large variety of subparts (such as brackets and hangers) – enabling simple, efficient maintenance.

A primary advantage to conductor bars is their viability in multi-bridge runway systems. In addition, conductor bars may be adjusted to suit indoor and outdoor cranes and perfectly accommodate low ceiling environments with limited dropdown power cable spacing.

Because of their versatility, conductor bars are ideal for regularly upgraded systems or in retrofitting legacy operations. Power continuity between existing and new interlocking elements can be trivialized by introducing an appropriate conductor unit. In addition, the straightforward installation allows runways to be extended without excessive logistical challenges related to power supplies – cutting project lead times.

Related Overhead Crane Systems & Components

Industrial overhead cranes can be equipped with a wide variety of accessories and modifications. Implements include:

  • Bare and insulated conductor bars. Bare options provide significant cost reductions in large-scale applications, whereas insulation increases operative efficiency and safety.
  • Spring and motorized cables/hose reels. Cable reels are intended to deliver power to the various industrial elements on a crane. Spring designs enable high power extension and retraction of the reel.
  • Festoon systems. Mobile supports for power cables that allow smooth, dynamic movement with trolleys or hoists.
  • Slip ring assemblies. Facilitates sensor interactivity and transfer of electric current from stationary to rotating / mobile elements.

Additionally, highly tuned optical positioning systems (OPS) may be employed to provide real-time feedback on machinery spacing, movement, and relative component locations. Positional awareness is a valuable tool for autonomous material management and programmed crane operation. OPS elements can be custom configured to new and existing overhead crane operations.

Signs Your Crane Wheels Need Replacing

Posted on by

Overhead cranes allow materials to be moved through the air. It frees the ground area for workers as they stay productive. Overhead cranes also move heavy loads onto specific conveyances, such as rail cars, and to production processes.

An important part of the overhead crane is the crane wheels. Crane wheels are part of the traveling system to move materials to different locations in facilities. Without them, the crane cannot function to move the materials. Due to the daily work that these parts go through, in time they need to be replaced. There are several signs to look for that may tell you when to replace your crane wheels.

Misalignment

The overhead crane may become misaligned on the tracks. Even with only a slight misalignment, this problem leads to the crane placing unnecessary heavy load stresses on certain parts of the system that are not used to carrying such stress. The misalignment may be due to broken wheel flanges or cracked wheel flanges. Wheel bearings or rails that have worn down prematurely may also indicate a misalignment.

In certain circumstances, the wheels will disengage from the rail and rise up before crashing back down. Even when getting the overhead crane realigned, you may have to replace the wheels after experiencing such hard crashes that could have caused damage to the bearings or wheels themselves.

Overcapacity

Workers want to get loads moved as quickly and safely as possible. However, they should only have the overhead crane move materials that fall within the capacity and service range of the machine. Placing on heavier loads leads to extra stress on the wheels and the truck when it moves along the rail This stress causes the wheels to fail due to excessive wear.

Excessive Damage

A sign that may indicate the wheels need to be replaced is excessive wearing on the wheels. While normal wearing is expected, there are times when the wheels, bearings, and flanges may wear down prematurely. The problem may occur due to overcapacity. Another issue causing wear impacts custom overhead cranes where the wheels are made from softer materials than required for the application.

Understanding the types of materials that will be moved will allow you to pick a material for the wheels that can withstand large stresses. Just keep in mind that the hardness of the wheel’s material should match that of the rails. If the rails are made from softer materials, they may experience damage from the harder wheels.

Loud Scraping

Running the crane for long periods of time may cause the wheels to begin to wear out. If the crane exhibits loud scraping noises when in operation while moving along the rail, it could indicate that there is a broken or a cracked wheel. All noises that are not part of the overhead crane’s normally operating system should be investigated and replaced immediately.

Keeping the overhead crane running efficiently means inspecting the wheels, wheel bearings, and wheel flanges for excessive wear, breakage, or cracks. If you are in need of specialty crane parts, turn to Kor-Pak. Contact us today to learn more.

A Guide to Industrial Brakes

Posted on by

Are you designing new equipment and need custom industrial brakes? Industrial brakes are often subjected to extreme heat and pressure. How do you know which brake is going to give a safe stopping force for your equipment?

Read our guide on types of industrial brakes and custom solutions for industrial applications.  

Industrial Caliper Disc Brakes

Disk brakes offer stopping force with less risk of overheating. The caliper on this braking system acts as a clamp that applies force to brake pads and slows rotation down. As a result, brake pad material creates friction against the rotating motion of the machine.

Industrial caliper disc brakes come in different types. They offer customization opportunities for smooth stopping on many industrial applications.

A pneumatic or air-applied spring system will work well for applications for large amounts of torque requirements. In addition, they offer reliable performance for emergency stopping and holding. 

Hydraulic systems can handle a higher torque range and are valid as safety brakes on many industrial applications. They will work well for your heaviest machinery. 

For applications in which frequent stops will occur, it is best to consult a specialist. Get help with calculating torque and choosing the correct disk brake application. Overuse with the wrong caliper can result in unreliable stopping and premature pad wear. 

Drum Brakes

Drum brakes have a shoe in the wheel hub that pushes outward on a drum when you apply the brake. Unfortunately, the shoe pushes into the surface, and friction slows down the rotation.

Drum brake systems are classified as fail-safe, spring-set, and electro-hydraulic thruster or magnetically released systems. 

One of the most significant benefits of drum brakes in industrial applications is their compact design. Where space is limited, drum brakes offer a safe and cost-effective solution. In addition, they work well in applications that do not generate lots of heat. 

Eddy-Current Brakes

The two previous brake systems reviewed apply force with contact. — pressing friction material against a disc or drum surface creates slow or stop.

Eddy-current brakes do not apply contact as the force to create stopping. Electromagnetic currents use a magnetic force against the rotating disc and prevent rotation. Eddy-current brakes are frictionless. 

A conductor must be moving for this force to work. So, Eddy-current brakes are not suited for stop holds. However, they are ideal for applications with high-speed movements for an immediate stop.
