    Repair method when the car lift tailgate fails

    The information comes from:the Internet posted on:2021-09-30

        The actual operation of the car lift tailgate is very simple. Only one person can complete various postures of the tailboard according to the button operation of the household appliance, and carry out the loading and unloading of the goods. It can very well consider the customer's requirements and suffer an unprecedented experience. A warm welcome. Today we will talk about the maintenance method when the car lift tail plate fails

        The structure of the car lifting tail plate:

        The car lifting tail plate is composed of: bearing service platform, transmission mechanism (including lifting cylinder, closing cylinder, adding cylinder, square steel support, lifting arm, etc.), bumper, piping system software, electronic control system (including fixed Fixed electrical control cabinet and line controller), oil source (including motor, gasoline pump, various hydraulic transmission systems, automobile fuel tanks, etc.).

        The lifting of the tailgate of the car is all equipped with a hydraulic control system. After a long time of application, it is inevitable that some problems will inevitably appear to be overhauled. Below, Shengfu machinery and equipment show some common common fault conditions, reasons and clearing methods.

        1. No action: The following is very likely to happen:

        1: The switching power supply of the car lifting tail plate of the loaded car is not connected, and the switching power supply is immediately connected.

        2: The commercial safety lock is blown, immediately turn on the wire controller and replace the fuse tube.

        3: The AC contactor is burned out, immediately dismantle and replace the AC contactor.

        4: The wiring of the rechargeable battery head is loose, check the wiring of the rechargeable battery head first, and connect it firmly again.

        2. The motor rotates, but it can't rise or fall.

         1: Check if the relay connector is loose, and if it is loose, connect it again firmly.

         2: See if the battery power consumption is sufficient. c: Check if the gear oil is sufficient.

         3. The motor does not stop after the button is released in time. Power off immediately and check whether the AC contactor and button are calcined.

         4. Oil leakage in the pipeline: check if the connector is loose and the gasket is damaged.

         If it is found that the hydraulic transmission system of the tailgate of the car has common faults, and it cannot be used normally, you can compare the above analysis to determine the cause and location of the common faults, and then solve them in accordance with the above methods.

         Nowadays, if manufacturers who can sell car lift tailgates on the market can overhaul the car lift tailgates, for example: Dongguan Youjiang Electromechanical Equipment Co., Ltd., the structural foundation of each tailgate is not much different, and it is not particularly complicated. , It is made up of electrical control cabinet, control panel, oil cylinder, hydraulic oil pump, pipeline, circuit system, etc. approximately.
