1. Smooth Operation
During lifting, there should be no jamming, abnormal noise, or significant shaking. Vibration or metallic friction sounds may indicate guide rail deformation, pulley wear, or loose fasteners.
The action response should be timely; the lifting mast should start immediately after a jog or remote control command, without delay.
2. Lifting Speed and Time
Under normal circumstances, lifting from the lowest position to the highest position (usually 6-10 meters) should be completed within 30-60 seconds. If it slows down significantly, it may indicate insufficient motor power, insufficient hydraulic system pressure, or worn drive chain.
The descent process should be uniform and controllable, with accurate braking points and no free fall.
3. Limit Switch Function Effectiveness
When reaching the maximum height, the system should automatically stop to prevent damage from overtravel. If it does not stop or requires manual intervention, the limit switch is malfunctioning.
After descending to the bottom, it should reliably lock to prevent accidental slippage during transportation.
4. Control System Response
The remote control and control panel buttons should be responsive, providing stable wireless control within a 30-meter range without malfunctions or false alarms.
In jog mode, precise height adjustments are possible, and in continuous operation mode, smooth performance is maintained.
5. Mechanical Structure Integrity
Check that the wire rope has no broken strands, no skipping, and uniform tension; the pulleys rotate freely.
The hydraulic rod or electric actuator should be free of oil leaks, bending, or deformation, and all connections should be secure.
The guide rail should be clean, free of obstructions, and well-lubricated.
6. Safety Protection Mechanism
The system should automatically stop lifting when an obstacle detection (if present) is triggered.
The motor should have an overload protection trip function to prevent burnout.
