Q: What is an overload protection device?
A: It is the safety sentinel of the hoist. It prevents the hoist from operating when the load is too heavy, protecting the machine and the people inside.
Q: Why is this device so important?
A: It is non-negotiable. It acts as the last line of defense against human error in load estimation, directly protecting lives, the hoist, and the worksite.
Q: How does it work?
A: It uses sensors to measure the actual load weight and compares it to the hoist's safe capacity. If the load gets too high, the system steps in.
Q: What happens when the load approaches the limit?
A: There is a two-stage safety intervention. First, a warning alarm activates. If the load continues to increase, the system cuts power and stops dangerous movements.
Q: Where is this device used?
A: It is a mandatory system on every modern passenger hoist used in construction. It is a legal requirement under safety regulations like OSHA and ASME.
Q: When is it most critical?
A: During lifts near maximum capacity, lifts with long cable lengths, and any lift where the load distribution could shift unexpectedly.
Q: What should I check daily before operation?
A: Check the display unit for clear readings and no error codes. Inspect all sensor connections and cables for damage, corrosion, or disconnection.
Q: How do I test if it is working properly?
A: Perform a warning alarm test to verify visual and audible alerts activate. Then conduct a cut-off action test using a known test weight to confirm the system stops hazardous motions.
Q: Does it need regular maintenance?
A: Yes. The entire system must be calibrated and certified by a competent technician after installation, after reconfiguration, and annually.
Q: What records should I keep?
A: Maintain all test and calibration records in the hoist's logbook. This is essential for safety compliance and inspections.
