The elevator is used to transport goods, generally in the vertical direction. Therefore, if the equipment fails to rise, it will have a great impact on the production process. Therefore, we must first find the reason why the elevator does not rise, and then find a targeted solution.
Through inspection, it is found that the failure of the elevator to rise may be due to electrical reasons, such as the wrong phase sequence of the power line, and the equipment itself lacks some protective devices, which makes the elevator unable to perform the correct action. Moreover, the damage of electrical components may also cause the hydraulic pressure to fail to work normally, and the main performance is the different rise of the equipment.
It may also be caused by the damage of the emergency stop button, the lifting limit or the limit limit, so that the main power contactor of the elevator or the contactor controlling the motor operation cannot be closed. In this state, it will become very difficult for the equipment to rise.
