What happened to the rise and fall
Replace when necessary. Indicator, press the up button, motor rotation and lifting platform does not rise inspection or greater power contact, inverted power supply after the motor, it can be power supply is correct.
The motor is missing (the motor is not moving, and there is a buzzing sound) to check the circuit breaker and the electrical wiring. The drop valve is open when the drop button is released, and the voltage meter is used to check if the valve has electricity. If there is no electricity, check the line and troubleshoot it. If there is electricity, the valve itself is out of fault. The slide valve must be clean and flexible. The overflow valve is adjusted to the relief valve. Under 100% rated load to adjust the oil level is too low, the oil pump hydraulic oil filled up at a empty absorption, oil absorption filter clogging, clean filter, oil leakage, check the suction tubing and connectors; Tighten the joint.
The first possible reason is that the voltage is too low to check the actuator potential of the motor load. The voltage fluid range allows for a plus or minus 10% of the motor to not inspect the two phases of the three-phase line of the motor and circuit motor.
The first possible reason is that the voltage is too low to check the actuator potential of the motor load. For users, a huge lift seems very mysterious, from which a small parts out of the question can let you helpless, Beijing force high lifting mechanical wang manager here to give you a little small pupil:
