A chain fall, commonly called a manual chain hoist, is a hand-operated device for vertical lifting. It uses a system of pulleys (sheaves) and a specially designed load chain to create a mechanical advantage. By pulling the hand chain, the user rotates gears that grip and raise the much stronger load chain, effortlessly lifting loads far heavier than human strength alone could manage. This makes the chain hoist a fundamental and reliable tool for controlled, precision lifting.
How is a lever block different from a standard chain fall?
While both are types of manual chain hoists, a lever block chain hoist offers unique portability and directional flexibility. Instead of being suspended from a fixed point, the operator uses a hand-held lever to ratchet the load chain. This allows for pulling, dragging, and lifting applications in multiple directions, not just straight vertical lifts. This makes the lever block an indispensable chain hoist for positioning, tensioning, and working in tight spaces where a traditional chain fall cannot be mounted.
Final Considerations for Choosing or Replacing Load Chain.
Now that you know more about the types of load chain used in overhead lifting applications, here are a few final considerations before you buy chain for your hoist.
- Always refer to your hoist’s owner’s manual for the proper size chain used in your hoist.
- Speak with a parts and repairs specialist to ensure proper installation of the replacement chain.
- Consider your lifting environment and if your chain will require specific features.
- Account for enough chain to supply the correct lift height by understanding the chain that will remain in the hoist at its max lift height. If you need a 10’ of single-reeved lift, you’ll need to order 12’ of chain so there is enough to feed through the unit. Understand your hoist’s reeving. If you have a double-reeved unit, you will need to order double the amount of chain plus the threading length
- Take care of your hoist by taking care of your chain. Make sure to inspect it regularly, lubricate it properly, and do not use a hoist with damaged chain.
