A tandem lift is a tricky, dangerous operation. The critical crane lifts require planning, experienced supervision, and precise execution. Without proper planning and execution, an operation can quickly turn into an OSHA statistic. 

Keep reading to learn about the engineering specifics involved in a critical lift. 

Planning a Critical Lift

Cranes and hoists working in tandem are like poetry in motion. When a plan goes right, the cranes move smoothly, with operators and supervisors working in a beautiful rhythm. 

Before the lift, though, much planning takes place. 

Anytime a hoisted load nears a crane’s maximum capacity, the load qualifies as a critical load. Maximum capacity refers to 70% to 90% of a crane’s capacity. 

More than weight capacity qualifies a lift as a critical lift. A lift is critical if the lift:

• Hoists personnel.
• Hoists hazardous materials.
• Requires two or more cranes.
• Occurs on a floating barge.
• Occurs near power lines.
• Occur in a blind spot, out of the view of the operator. 
• Involves technically difficult rigging arrangements.
• Occurs in congested areas. 
• Involves flipping or turning a load. 
• Involves an unknown load weight. 
• Occurs in unknown ground conditions or poor soil. 
• Involves unstable pieces. 

Any time that environmental conditions make the lift dangerous or any time a crane operator believes the lift is critical, the lift can qualify as critical. 

All crane lifts require pre-lift planning. Because the potential of crane failure or catastrophic loss is much higher with a critical lift, critical lifts require a thorough lift plan. 

Parts of a Critical Lift Plan

An experienced supervisor will be able to complete a critical lift plan with ease. It must have the following information in it: 

• The position and configuration of the crane or cranes involved. 
• A description of the lift. 
• Height of the lift. 
• Load radius. 
• Boom angle and length. 
• Percent of the crane’s rated weight capacity. 
• Size and weight of the load.
• Rigging plan. 
• Personnel involved. 
• Communication method. 
• Environmental conditions, including the ground conditions. 
• Inspection procedures. 

Each of these elements ensures a safe lift in critical conditions. Without proper planning, the critical lift can turn deadly. 

The Feat of Tandem Cranes

Cranes working in tandem are responsible for the architectural and engineering feats we take for granted every day.  The beautiful hospital on the horizon of our city or the multi-tiered freeway we take to work is all a result of skilled engineers and crane operators working in tandem to put the pieces together.

Because a tandem lift is a critical lift, it requires the same kind of lift plan. However, because two cranes are working together, the tandem lift plan has more requirements.

Critical crane lifts involve tandem crane operations must have a written lift plan with the following details to ensure a safe lift: 

• Crane positioning
• Lift sequence
• Load movement including the exact measurements of the longest radius of each crane)
• Load distribution and transfer
• Boom clearance
• Clearance and weight of obstructions
• Environmental considerations
• The rated capacity for each crane involved
• Angle indicators for each crane
• Wind speed limitations
• Rigging details
• Maximum hoist line
• Maximum crane travel speed
• The need for and the position of signalers

Because of the complexity of having multiple cranes working on a single operation, you need an experienced supervisor. The supervisor may not operate the powered lifting equipment. 

Big Beautiful Builds

The key to a successful critical lift is communication, reliable equipment, and knowledgeable supervisors. The results are some of the most amazing human-made structures on earth.

Mastering the Demag Hoist: Tandem Lift

A Demag all-terrain crane (Demag AC 500-2) successfully participated in a tandem lift with a Tadano ATF 400G-6 in December 2020. The two cranes lifted a pressure vessel off a roll-on/roll-off pontoon and onto a self-propelled modular transporter. Tandem lifts are difficult to execute and are defined as critical lifts.

The pressure vessel weighed 138 tons and had a length of 12.8 meters. The Demag AC 500-2 has a capacity of 500 tons. It was equipped with 140 tons of counterweight to lift its load portion of 88.5 tons at a radius of 15 meters.

The Tadano ATF 400G-6 has a capacity of 400 tons. It had 98 tons of counterweight to lift the remaining 49.5 tons and a radius of 15 meters.

The joint lift enabled the self-propelled modular transporter to carry the pressure vessel to its destination by land. The pressure vessel reached its destination safely. After a period of temporary storage, it received maintenance and was placed on its foundation.

Demag Crane Success: All-Terrain in Mumbai

A Demag AC 1000-9, the largest Demag all-terrain crane, successfully lifted a 100-ton tunnel-boring machine from below ground up onto the middle of Mumbai’s surface. The lift was part of construction on the Mumbai Central Metro station.

To lift the tunnel-boring machine, the AC 1000-9 used its full 228-ton counterweight at a radius of 20 meters.

The restricted space in the city center and the project’s tight timeline required exceptional preparation and execution. The crane service provider had to move the AC 1000-9 from their workshop to the worksite on multiple trips overnight. They avoided the traffic in Mumbai and could get the crane and its equipment into the job site.

The team completed the challenging lift precisely and within the project time frame.

Overhead cranes are an impressive piece of industrial machinery. The largest payload ever lifted by an overhead crane was over 20,000 metric tons. While your equipment might not have that lifting power, it still needs to be operated safely.

Load testing is an integral part of keeping your crane well-maintained and in safe working order. But what is load testing, and how is it relevant to your equipment? This informative guide has all the information you need.

Load Testing Defined

Load testing is the process of inspecting a crane’s lifting abilities to ensure all parts are in working order. This is often done by lifting a load or applying pulling pressure to the crane using load testing tools. The performance results are then analyzed.

This simulates actual day to day crane lifting operations. It is essential to get load testing done on all overhead cranes. Chain hoist, electric hoist, and engine hoist cranes should also be load tested before use and at regular intervals.

Each of your crane’s components will be evaluated during the load test. If any of these individual components fail, your crane as a whole will fail as well.

Why Should I Get My Crane Load Tested?

Getting your crane load tested is imperative to protecting the safety of your employees. If your crane isn’t load tested, it is more prone to failure. In the case of industrial machinery, most failures are catastrophic. Loss of life and limb can occur.

Load testing for overhead cranes and hoists are also required by law. If your company is caught operating a crane without first having a load test, you can face a hefty fine or other penalties.

Contacting a professional is usually your best bet if you don’t have the right load testing tools on hand at your facility. You can get your crane load tested as part of your regular crane inspection routine. 

If your crane fails the load test for whatever reason, it is far better than failing in the field during normal operations. Load tests act as a buffer for the safety of your employees and the wellbeing of your equipment.

You should conduct load tests regularly following local, state, and federal laws. You can contact OSHA for more details about load testing standards and any other laws applicable to your industrial equipment.

Can Your Overhead Crane Pass the Test?

If your overhead crane is unable to pass a load test, it should not be used in day-to-day operations. Load testing is an integral part of maintaining safety in the industrial workplace.

Without load tests, there would be many more deaths and injuries attributed to cranes. The lifetime of overhead cranes would also decrease as well due to an increase in mechanical breakdowns. Get your overhead crane load tested today!

In 2019, the rate of nonfatal occupational injuries among employees was 2.8 cases per 100 full-time workers. Any business should keep their employees safe, but it can be challenging for industries that work with heavy machinery. Luckily, there are things you can do to ensure your operators are working safely.

Read on to learn about how your overhead crane operator can be up to spec.

Require Proper Training

An overhead crane operator should have the proper training and certification to operate the equipment safely. Training includes knowing the right procedures and measures to take at any moment.

For the best overhead crane safety, a company should provide training that includes classroom and hands-on instruction. A variety of topics that should be covered are hazard identifications, safety, safe maneuvering, and safety features.

Overhead crane training should also implement proper start-up and run-down procedures. A crane operator that can understand how to lift loads and know the machine’s capacity will be safer in the business.

Training should not be a one-time thing. When working with dangerous machinery, it is essential to provide operators with refreshers when needed.

Look out for workers who may be operating equipment incorrectly and using it for an unintended purpose. This is a telltale sign that an operator requires retraining. Only those trained to operate equipment should do so.

Inspect Before Use

An overhead crane inspection should be done before using it every single time. This will help ensure that the machine is in the proper operating condition.

Overhead crane service inspections should include checking for wear and damage, checking fluid levels, and other components for cracks. Before starting up the machine, an overhead crane operator needs to check the engine oil and hydraulic fluid levels.

After doing an outside check, start the machine to ensure the gauges and lights are working correctly. The operator should also check the alarms.

Listen for any odd sounds or smells coming from the machine. If there are any signs of damage, do not use the equipment. This could lead to further damage and safety issues for the entire staff.

Teach Proper Entering and Exiting Techniques

With many work injuries suffered each year, it is essential to know how to avoid an injury at all costs. This includes teaching your operators about how to enter and exit heavy machinery the right way.

Similar to climbing a ladder, an operator should get into equipment by maintaining three points of contact. Make sure hands are free as nothing should be carried while entering an overhead crane.

When exiting, an operator should not jump out or off of the machine. This should go without saying, but equipment that is in operation should not be entered or exited.

Before exiting, an overhead crane should be completely shut off, and the brakes should be on. Always put the keys in a safe place to ensure there is no unauthorized use.

Keep an Overhead Crane Operator Safe

Ensuring your overhead crane operator is up to spec begins with you. Before allowing them to use the machine, make them go through the proper training. Keeping your operators and other workers safe can be done by using this guide.
