Reason: The lowering valve is not tightly closed. Cleaning method: Check if the lowering valve is powered on. If there is no power supply, clear the malfunction of the lowering valve itself or replace the lowering valve. It is necessary to keep the valve of the lowering valve clean and flexible.Considering the oil level in the oil tank, when all hydraulic cylinders in the system are extended,HorovHydraulic lifting platform, the oil level in the oil tank should not be lower than the Z-low oil level, and when the oil cylinders retract, the oil level should not be higher than the Z-high oil level. In fact, most manufacturers have noticed the above issues. The reason for the introduction is that most users can learn more about the equipment itself when using elevators, in order to facilitate equipment maintenance. Hydraulic cargo elevator manufacturers sincerely hope that you choose a legitimate manufacturer when purchasing elevators, to avoid any worries about after-sales service.Horov,Below, we will analyze for everyone. According to the market survey and understanding conducted by the editor of hydraulic freight elevator manufacturers, many customers choose hydraulic elevators instead of elevators due to the following reasons: narrow transportation location,. The hydraulic oil enters the upper end of the hydraulic cylinder through the explosion-proof electromagnetic directional valve and should be stable at the maximum lifting height.Bandaria, 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. In order to ensure a smooth descent of heavy objects and safe and reliable braking, a balance valve and balance circuit are installed on the return oil circuit to maintain pressure and ensure that the descent speed is not affected by changes in heavy objects. The throttle valve regulates the flow rate and the lifting speed. To ensure safe and reliable braking and prevent accidents, also known as a hydraulic lock, is added to ensure safe self-locking when the hydraulic pipeline bursts. Install an overload sound alarm to distinguish between overload or equipment failure.Therefore, the wholesale manufacturers of hydraulic elevators remind that there are three main ways to adjust the speed control circuit: throttling speed control circuit: quantitative pump oil supply, using flow valves to adjust the flow in and out of the actuator to achieve speed control; In the volume throttling speed control circuit, the oil is supplied by the pressure limiting variable pump, and the flow rate into the actuator is adjusted by the flow valve to adapt the flow rate of the variable pump to the regulated flow rate of the speed control valve.The precautions to consider when selecting a hydraulic lift oil tank include: considering the structure of the oil tank, 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, which improves the utilization rate of the well surface.After hours of operation on the hydraulic lift major repairs will be carried out to the mechanical and electrical systems.The cheapest,The contact of the travel switch must be firmly opened and closed, and the contact crater should be polished in a timely manner.The installation personnel should have the qualification for installing hydraulic cargo elevators, carefully implement the special construction plan for installation and construction, and provide safety technical disclosure to the installation personnel for technical design.When encountering signs of overheating in the electric motor, it is necessary to park the car in a timely manner, clean the problem, and continue running. The motor bearings should be smooth and outstanding.

The lifting platform is placed on a horizontal support surface, and the concentrated load of MAX load capacity is placed at any position mm away from the periphery of the workbench. After lifting times, each load-bearing component must not have deformation or cracks.resources,What are the methods for reducing shaking on lifting platforms? Reducing the shaking of the lifting platform can reduce the psychological obstacles of the operators, ensure the smooth progress of the operation and also greatly help improve safety. Warm reminder: safety, do not operate blindly. Lifts are widely used in many places, and their working principles vary. Today, we will analyze the working principles of elevators. The types of elevators are generally divided into the following: fixed elevators, This type of elevator uses hydraulic oil cylinders and pump stations to transmit power, in the form of a scissor fork type. According to customer requirements, the length of the support rod for the scissor fork, the number of layers, the angle of the angle axis, and the expansion and contraction of the oil cylinder complete the lifting operation. Its advantages are large load-bearing capacity, stable lifting, and high safety.Hydraulic cargo elevator sinking refers to the lifting of the cargo elevator equipment to a designated position,HorovHydraulic lifting platform,HorovHydraulic fixed lifting platform, and after a period of time, the entire table surface will automatically descend by a certain distance under its own weight. The phenomenon of hydraulic cargo elevators naturally descending during the leveling process. This phenomenon is definitelyAfter hours of elevator operation, perform minor repairs to the mechanical and electrical systems.Horov,Pay attention to checking each steel wire rope for signs of broken wires and loose drums. If it exceeds the relevant rules, it is necessary to replace it immediately. The protection of steel wire ropes should strictly follow the rules of GB-. There is air in front of the pilot valve of the elevator overflow valve noise overflow valve. The damping hole on the main valve core of the overflow valve is blocked by oil dirt, and the pilot valve and valve seat are matched without spring deformation or incorrect installation. The remote control port has excessive oil flow, low or high hydraulic oil viscosity, and resonance occurs with components in the circuit. Troubleshooting: Strengthen sealing, exhaust and clean the valve body several times, Make the damping hole unobstructed repair or replace the spring, reduce the flow of the remote control port, replace the oil, and other components. The pressure setting of other components should not be similar to the pressure setting of the relief valve. . The noise of the elevator pipeline is usually caused by excessive dead bends or loose fixed sleeves in the hydraulic pipeline.After the pre installation is completed, the pre installed equipment should be fixed, and the positions of cables, oil pipes, and components such as the pre installed frame should be confirmed to be correct before reinforcement work can be carried out. Reinforcement requires welding or screws, and the hydraulic cargo elevator after reinforcement has robustness and safety.
