What are the common faults and solutions of electric hanging basket

As an important equipment for aerial work, electric hanging basket may have various faults during use. For these faults, we need to have detailed analysis and solutions to ensure the safety and efficiency of construction. The following is a detailed introduction to some common faults of electric hanging basket and their solutions.

Common faults of electric hanging basket

Power supply problem

The power indicator light is not on: check whether the power is connected and whether the transformer or bulb is damaged.

The motor does not rotate: it may be a phase loss, a phase failure inside the motor, or the wire rope is stuck in the hoist. It is necessary to check the circuit and replace the damaged parts.

Mechanical failure

The hoist cannot start: it may be that the power plug is not plugged in firmly, the start button is damaged, the fuse is blown, etc., and it needs to be repaired or replaced according to the situation.

The hoist brake does not work: it may be due to no DC voltage, damaged rectifier tube, damaged fuse, etc., and the damaged parts need to be checked and replaced.

Electrical failure

The limit switch does not work: it may be that the power phase sequence is reversed, the limit switch is damaged or the contact is poor, and the phase sequence needs to be exchanged or the limit switch needs to be replaced.

The motor automatically slides down after power failure: it may be that the wire rope is stained with oil, the rope wheel groove is worn beyond the standard, or the motor brake fails. It is necessary to remove the oil stains, replace the rope wheel or adjust the brake.

Other faults

The operation control is down but not up: it may be a limit switch fault, a start button fault or an up contactor fault, and the limit switch or contactor needs to be replaced.

The angle of the safety lock rope is too large: it may be that the spring in the safety lock is damaged or there is too much dirt, which needs to be cleaned or sent back for repair.

Solution

Solution to power supply problems

Check whether the power switches at all levels are effectively closed, and replace the transformer or bulb if necessary.

Solution to mechanical faults

Inspect and repair the disassembled hanging basket parts, such as cleaning, lubrication, and replacement of damaged parts.

Solution to electrical faults

Check whether the power line is short-circuited or open-circuited, and whether the motor is damaged.

Solution to other faults

After the maintenance is completed, perform a functional test on the hanging basket to ensure that the hanging basket can operate normally.

Troubleshooting of electric hanging baskets is a complex process, which requires comprehensive consideration of power supply, mechanical, electrical and other aspects. In actual operation, the operating procedures should be strictly followed to ensure safety. At the same time, it is necessary to choose appropriate maintenance methods and materials according to the specific situation to avoid blind actions that lead to greater damage. Only in this way can the normal operation of the electric hanging basket be effectively guaranteed, thereby ensuring the safety of high-altitude operations.
