Fred Coffing designed the first modern chain hoist in 1918 to make work easier on his family’s apple orchard. Chain hoists have developed significantly since the early 1900s.
Electric hoists have a high load capacity. They’re durable and cost-effective.
Selecting and maintaining an electric chain hoist is covered here.
How to Choose the Right Electric Chain Hoist
Electric chain hoists are a low-maintenance and reliable option for lifting and lowering loads. However, choosing the right equipment for the application helps ensure you get the best performance. Several factors are essential to consider.
Weight of the Load
The weight of the loads you need to lift is a primary consideration when looking for an electric chain hoist. First, calculate the average and maximum weights you intend to raise.
Leaving a margin between the weight of the load and the hoist’s capacity is a good idea. Consistently working a hoist at its maximum capacity can cause the equipment to wear faster. You can perform better over time with a hoist that can comfortably handle the job.
Power Requirement
The job site needs appropriate wiring for the hoist.
A single-phase electric chain hoist will plug into a standard electrical outlet. This type of hoist is ideal for mechanics or smaller machine shops.
Single-phase systems aren’t powerful enough for large industrial operations. Hoists that handle heavy loads regularly need three-phase power. It is more efficient and reliable.
Duty Cycle
The duty cycle refers to the time the equipment can operate continuously under normal conditions. For example, an electric hoist with a 25% duty cycle could run for 15 minutes before needing a period to cool down. Using a hoist beyond its duty cycle can shorten its service life.
Lifting Speed
The speed of the electric hoist affects productivity and efficiency. The speed should be enough for the height of the lift. If the rate is too low, you need too much of the duty cycle to raise a single load.
Mounting an Electric Chain Hoist
The best way to mount an electric hoist depends on the facility and the usage of the hoist. Electric hoists can be suspended in a fixed position or trolley-mounted.
A lug suspension is a highly secure fixed suspension. It can be a good choice for permanent applications. A top hook suspension can attach the hoist to a beam clamp or trolley.
Trolleys can be motorized or manually operated. Motorization is vital for heavy or bulky loads. A motorized trolley lets the operator manipulate the load from a distance.
Electric Chain Hoist Maintenance
Regular maintenance helps keep your electric chain hoist in top condition. As a result, you can avoid worker injuries and costly downtime. It also keeps your facility compliant with OSHA regulations.
Preventive inspections can identify possible risks before they become serious issues. First, an inspection looks for signs of wear or damage. The checklist should include parts such as the chain, chain drum, electric brake, and spring brake.
Routine maintenance can include:
- Lubrication and adjustments
- Replacement of worn parts
- Electrical repairs
- Load testing
This type of maintenance is essential for the safety and productivity of your facility.
