Misconceptions

Misconception 1. If you have attended a training course you are a competent rigger.

Training is only one part of being competent to carry out your job, you must also be adequately qualified and have sufficient experience.

Read Details

Misconception 2. When operating a lever hoist, the operater can use as much force as required on the lever hoist handle.

Hoists shall not be operated by other than the hand-power of one operator. Hoists shall not be operaterd with an extension on the lever. Most manufactuerrs have a maximum allowable force that can be applied for full load rating to be achieved.

Read Details

Misconception 3. The lever hoist chain can be wrapped around the load when lifting.

The hoist chain shall not be wrapped around the load

Read Details

Misconception 4. The lever hoist chain can be used to craddle the load when lifting.

The hoist chain shall not be wrapped around the load or be used to craddle a load.

Read Details

Misconception 5. If fitted with a slip clutch this is set at 100% of the rated load.

The setting of a slip clutch when fitted to a lever hoist can vary massively from manufacturer to manufacturer. It can be as high as 160% - 200% of the WLL and can vary due to use and condition of the lever hoist.

Read Details

Misconception 6. Latches on the lever hoist hooks can be in the open postion when applied to a load or rigging.

When a hook is fit with a latch the latch is there to retain slings or rigging under no load conditions. Latches must be closed and must not be affected by the rigging when lifting.

Read Details

Misconception 7. When using lever hoists as a balancing leg on a multiple point lift, a back up sling should be used in case of a lever hoist failure.

This is sometimes a site specific requirement but there is no legislation to say this is a requirement

Read Details

Misconception 8. Lever hoists are not affected by varying temperatures.

All lever hoists are affected by temperatures and the manufacturer must be consulted to see what temperature ranges the hoist can be used within are.

Read Details

Misconception 9. Lever hoists can only be used as a lifting device and not be used as a balancing leg in a multi-leg lift.

Lever hoists may be used as a balancing leg or as a sling in a multi leg lift as long as it is within its rated capacity and meets the requirements of the manufacturer as to its application. Many lever hoists have a design factor of 4:1. In cases where a 5:1 design factor is required in a multi leg lift and a lever hoist is used, the capacity of the lever hoist may have to be de-rated to achieve a 5:1 design factor.

Read Details

Misconception 10. Lever hoists can be used with the hoist out of line as long as the chain is in a direct line.

The lever hoist shall not be operated until the hoist body, load block and load chain are directly in line with the direction of loading to avoid side pulling.

Read Details

Misconception 11. It is acceptable to operate the lever hoist while the load is suspended when the lever hoist is being used in a multiple sling lift to balance a load.

The operator shall not apply a load to the hoist until the operator and all other personnel are clear of the load
