-
Welding or hammering on suspended loads, or working beneath suspended loads, is prohibited (except when properly supported).
-
Inspection or maintenance work may only be performed after power has been disconnected and a “Do Not Operate” sign is displayed on the power switch. If live work is unavoidable, implement safety measures and assign dedicated supervision.
-
Do not throw objects from the vehicle indiscriminately.
-
Regularly inspect limit switches and interlock protection devices.
-
Do not use limit switch impact as a stopping method.
-
Do not lift or lower loads when hoist brakes malfunction.
