The deviation of explosion-proof steel wire rope electric hoists during walking can be attributed to a variety of factors. Here are some of the most common reasons:

Hydraulic System Faults:

Motor issues: Faults such as excessive internal leakage in the motor can lead to uneven speed between the left and right motors, causing deviation.

Valve malfunctions: Problems with the main valve, brake valve, or control valve can result in uneven hydraulic pressure or flow to the motors, causing deviation.

Hydraulic fluid contamination: Contaminated hydraulic fluid can cause valve sticking or improper valve operation, leading to deviation.

Controller Faults:

Improper control signal inputs or misinterpretations can result in inaccurate positioning of the hoist.

Faults in the control system's sensors or software can also lead to deviation.

Mechanical Wear and Tear:

Wear and tear on mechanical components such as gears, bearings, and pulleys can affect the precision and stability of the hoist.

Uneven wear on the wire rope or guide pulleys can cause the hoist to deviate.

Installation and Alignment Issues:

Incorrect installation or alignment of the hoist can lead to deviation. This may include issues such as misaligned pulleys, uneven support surfaces, or incorrect mounting angles.

Environmental Factors:

External factors such as wind, temperature changes, or vibrations from nearby equipment can affect the operation of the hoist and cause deviation.

Operator Error:

Incorrect operation or misinterpretation of control signals by the operator can also cause deviation.

To prevent deviation, the following measures can be taken:

Regularly inspect and maintain the hoist, including checking the hydraulic system, control system, and mechanical components.

Ensure proper installation and alignment of the hoist.

Monitor environmental conditions and take steps to mitigate their impact on the hoist's operation.

Provide training and supervision for operators to ensure they are operating the hoist correctly.

Conduct regular testing and calibration of the control system to ensure accurate positioning.
