What Are the Functions of the Limit Switch for Chain Electric Hoist?

The limit switch plays a vital protective role during the operation of the HHBB chain electric hoist and prevents the risk of heavy-load falling. What specific functions does the limit switch of the electric hoist have? Hebei Shengyu Lifting Machinery Manufacturer gives a detailed introduction:

As a key safety protection component, the limit switch for chain electric hoist includes an upper limit switch and a lower limit switch. When the hook rises to its extreme position, the upper limit switch automatically cuts off the hoisting power supply. It prevents the hook from over-traveling and hitting the equipment body, avoids forcible chain breakage, and eliminates the risk of load falling. When the hook descends to the low-limit position, the lower limit switch cuts off the lowering power supply to prevent full chain payout, chain disengagement and chain misalignment.

The limit switch avoids equipment damage and safety accidents caused by misoperation. It protects the hoist unit, chains and suspended loads, serving as a basic safety protection device for lifting operations.

Hebei Shengyu Suggestion: Regularly check whether the limit switch works sensitively and reliably in daily operation of the chain electric hoist. Never remove or bypass the limit protection without authorization to ensure stable and safe lifting work. For inquiries and quotations, please call: 15133220073, Email: sherry@syhoist.com.
