What should be checked first if the hoist does not move during operation?

The appropriate first step when a hoist fails to move during operation is to inspect the power supply and control systems. This is critical because the hoist relies on electrical power and proper functioning of its control mechanisms to operate. If there is an issue with the power supply, such as a blown fuse, a tripped circuit breaker, or a disconnected power source, the hoist will not receive the necessary energy to function. Likewise, if there are problems with the control systems, such as faulty switches or wiring issues, these can also prevent movement.

Inspecting the hook for damage and verifying the operator's manual, while important, pertain to different aspects of hoist safety and functionality. The weight of the load is essential to check, but if the hoist is not moving at all, the likelihood of the load being too heavy is less relevant than ensuring that the hoist is getting power. Therefore, starting with the power supply and control systems is the most logical and efficient troubleshooting approach.
