When a rack and pinion hoist is not plumb, level, and square, several issues can arise that impact its operation. One significant consequence is the potential for the safeties to engage. Safeties are critical safety features designed to prevent accidents and ensure the hoist operates within safe parameters. If the hoist is misaligned, the load may not be balanced correctly, which can trigger the safety mechanisms to activate and halt the operation of the hoist. This is crucial for preventing further misalignment or structural damage and ensuring the safety of both the equipment and personnel involved in its use.

While operating slowly, motor overload, and unnecessary vibrations can also occur from misalignment, the immediate reaction of engaging safeties is a direct safeguard against malfunctioning equipment that could pose risks. Therefore, focusing on the activation of safeties is a key response to a rack and pinion hoist that is not properly aligned.
