Chain hoists may experience operational failure during use due to various reasons. Here are some common reasons and corresponding solutions:

Reasons:

Power issues:

The power supply is not connected properly or the voltage is too low.

The power cord is not correctly connected, leading to phase protection activation.

Internal circuit problems:

Internal short circuits or poor contact of braking switches.

Burnt-out fuses in the control circuit or power supply.

Motor issues:

The motor is making noise but not rotating, possibly due to incorrect motor phase.

Motor damage.

Wire problems:

Fractured or poorly connected wires in the power line or control circuit.

External factors:

Overload usage beyond the rated capacity of the chain hoist.

Poor lubrication or wear and tear of internal components.

Solutions:

Check and connect power:

Ensure the power supply is properly connected and the voltage is within the required range.

If the power cord is incorrectly connected, swap the phase wires.

Inspect and repair internal circuits:

Have a qualified electrician inspect and repair any internal short circuits or poor contacts.

Replace burnt-out fuses.

Inspect and repair motor:

Check the motor phase and adjust if necessary.

If the motor is damaged, replace it.

Repair or replace wires:

Repair or replace any fractured or poorly connected wires.

Operate within rated capacity:

Ensure the chain hoist is not overloaded and operated within its rated capacity.

Regular maintenance:

Perform regular lubrication and inspections to identify and fix any wear and tear issues.

Contact professionals:

If the problem persists, contact qualified professionals for further inspection and repair.

Remember to always prioritize safety when dealing with chain hoists and follow the manufacturer's instructions and safety standards.
