Nettet16. jul. 2012 · The hoist’s constraints should also be well understood. Pay attention to the pull to lift full-load values. Each hoist is designed to lift under the power of one person. It should not take two people to pull on a hand chain or lever arm, nor to put an extender on a lever tool (cheater bar). This is a sure sign the hoist is overloaded. NettetLifting devices may be fixed (e.g., overhead floor-operated crane) or mobile (e.g., mobile crane, boom truck). Lifting devices are typically powered (e.g. electric, hydraulic, air) but may be manual (e.g., small hoist, pulley blocks).
