Study Notes
Hoisting Devices and Safety
- A hoist is a device used for raising or lowering heavy or bulky objects, such as machines and equipment.
- Hoisting involves using a rope, cable, sling, or chain strong enough to support the load, a method of connecting the ropes, cables, or chains to the load, and a hoisting device.
- Hoisting is a hazardous operation that must be done by trained and experienced tradespersons.
Pre-Hoisting Checks
- Determine the number and locations of slings needed to balance the load.
- Determine whether the lifting devices are strong enough to handle the load.
- Check if the lifting device can raise or lower the load to the required elevation.
- Check if the beams or overhead supports are strong enough for the load.
- Identify hazards that may be encountered during the lifting and moving operation.
Block and Tackle
- A block and tackle is a combination of ropes and pulleys.
- It was a common lifting device in many plants, but is less preferred today.
- It should be stored properly to prevent damage.
Chain Hoists and Come-Alongs
- Chain hoists are used for vertical lifting, while come-alongs can be used in any position.
- Chain hoists have a lower hook that is weaker than the top hook and may distort if overloaded.
- The load should always be less than the rated capacity of the block.
Safety Checks
- Most jurisdictions require hoisting devices to have safety hooks with a self-closing latch.
- Never "choke" the load with the lift chain or strap.
- Use a sling or grab chain instead.
- Use a shackle to hold multiple eyes together when lifting.
- Keep away from the load or ropes when heavy stress is applied.
