Never put an extender (cheater bar) on a lever tool. This is a sure sign you are overloading the hoist. If it takes 58 pounds of pull force to raise one ton, any pull force over this value will overload the hoist. Consult the manufacturers specifications and train your operators on what each pull force should be. Many domestic (and some foreign) hoist manufacturers offer overload protection devices, either as standard equipment, or as an added cost option. This device protects the user, the overhead structure, and the hoist from an excessive overload condition. In powered hoists, this is usually a slip clutch within the gear case or on the drive of the motor. For hand hoists several hoist manufacturers utilize a friction type clutched hub as part of the hoists chain wheel or lever arm. When the pull on the lever or hand chain is great enough to slip the clutch and prevent the load from being lifted, the operator becomes aware that the hoist is overloaded. Hoist inspectors should be properly trained in hoist maintenance. A good maintenance and inspection program is critical to ensure hoist safety. ASME B30.11 has added the requirements for training for anyone maintaining hoist equipment.
