Motor not running: Check all components of the motor for damage and check if there are any problems with the circuit and wiring.
Hydraulic lift cargo elevators belong to high-altitude work equipment. Small shaking of the scissor type structure is normal, but excessive deviation is a symptom. It is necessary to find the cause and make correct judgments in a timely manner. Generally speaking, operations above 8 meters are generally allowed. Due to its own weight, devices above this height begin to vibrate in different ranges. The vibration range depends on factors such as weight, lifting height, and intensity of high-altitude operations.
Xiqing.The manufacturer of hydraulic cargo elevators tells you the precautions for high-altitude operations.
A hydraulic elevator is a type of elevator equipment consisting of a walking mechanism, hydraulic mechanism, electric mechanism, and enters the lower end of the hydraulic cylinder through an oil filter, explosion-proof electromagnetic directional valve, throttle valve,XiqingLifting hydraulic platform, hydraulic control one-way valve, and balance valve, causing the hydraulic cylinder to move upwards and lift heavy objects. The return oil at the upper end of the hydraulic cylinder returns to the oil tank through the explosion-proof electromagnetic directional valve, and its rated pressure overflow valve is adjusted. The pressure gauge observes the reading value on the pressure gauge.
. Road noise can also occur if tires are crushed against objects that are prone to noise. The shaking amplitude of the scissor type lifting platform is proportional to its lifting height. The higher the height, the greater the shaking. When using it at a working height of 10 meters, if possible, please use safety protection measures
Next, the hydraulic cargo elevator manufacturer will explain the maintenance of the mechanical equipment of the elevator: the brakes of each organization should be frequently checked and adjusted to ensure the clearance between the brake pads and wheels is sensitive and reliable. On the surface, there should be no dirt present. If there is dirt, or damaged bearings, which cause electric motors to sweep and produce noise; The cooling fan of the electric motor is damaged or not firmly fixed,XiqingFixed hydraulic elevator, resulting in high noise; The electric motor is not firmly fixed and can also cause vibration, producing high noise.
The downward movement of the hydraulic cylinder (i.e. lowering of heavy objects). The hydraulic oil enters the upper end of the hydraulic cylinder through the explosion-proof electromagnetic directional valve, and the return oil from the lower end of the hydraulic cylinder returns to the oil tank through the balance valve, hydraulic control one-way valve, throttle valve, and explosion-proof electromagnetic directional valve. To ensure a smooth descent of heavy objects and safe and reliable braking, a balance valve is installed on the return oil circuit to balance the circuit and maintain pressure, a hydraulic control one-way valve, also known as a hydraulic lock, is added to ensure safe self-locking in the event of an accidental rupture of the hydraulic pipeline. An overload sound control alarm has been installed to distinguish between overload or equipment failure.
Hydraulic oil deteriorates or produces impurities. After long-term use of oil pressure, there may be impurities or deterioration in the oil. Sampling inspection should be carried out to see if there are solid particles, discoloration, and odor. If necessary, and it is necessary to check whether the hydraulic pipeline is smooth. Focus on checking whether each type of hydraulic valve includes one-way globe valve, electromagnetic directional valve, proportional control valve, overflow valve, etc. If there are problems, the hydraulic valve should be cleaned or replaced in a timely manner.
Volume speed control circuit: Speed control is achieved by adjusting the displacement of a variable pump or variable motor.
how.Stability: The workbench should evenly withstand 125% of the MAX load capacity and be stable at the MAX elevation.
The vibration range is proportional to the lifting height. The higher the height, the larger the shaking range, especially for mobile hydraulic cargo elevators. When the working height exceeds 10 meters the wind ropes at the four corners of the hydraulic cargo elevator should be tightened to strengthen leg protection, and reduce shaking.
The precautions to consider when selecting a hydraulic lift oil tank include: considering the structure of the oil tank increase stability, the partition in the traditional oil tank cannot settle dirt. A vertical partition should be installed along the longitudinal axis of the oil tank, with a space left between one end of the partition and the end plate of the oil tank to connect the gaps on both sides of the partition. The inlet and outlet of the hydraulic pump are arranged on both sides of the partition at the disconnected end, so that the distance Z between the inlet and return oil is far, The hydraulic oil tank has more heat dissipation effect.
When the hydraulic oil is insufficient, the hydraulic pump will experience suction causing air to enter the hydraulic oil and producing high noise.
Click to view.Stable and widely applicable cargo lifting equipment is mainly used for transporting goods between height differences in production lines; Material online and offline; Adjust the height of the workpiece during assembly; High altitude feeder feeding; Lifting of components during assembly of large equipment; Large machine material and cutting; The warehouse loading and unloading site is equipped with forklift and other transportation vehicles for rapid loading and unloading of goods.
When loading and unloading goods at the dock, hydraulic cargo elevators are often used. What are the advantages and disadvantages of hydraulic cargo elevators compared to electric cargo elevators?
The smoothness of the gearbox, gearbox, external meshing gears, and hydraulic oil are all carried out according to the requirements in the smoothness table.
Xiqing.If the circuit of the device is not disconnected or lowered, it is necessary to check the fuse for repair and replacement.
After 1500 hours of elevator operation, perform minor repairs to the mechanical and electrical systems.
When the hydraulic lifting platform is working, the load cannot exceed its rated load. When it is raised to a certain height, the larger the mass of the object the greater the shaking
