Preparation for commissioning of hydraulic scissor lifts

Stationary hydraulic scissor lift

After the mobile hydraulic lift is installed, it must be commissioned. The following work should be done:
1. Wash the hydraulic hydraulic lift several times. The fuel tank and various lubrication equipment should be filled with lubricating oil. The sliding surface should be oiled many times. The lubricating points should maintain sufficient lubricating oil.
2. The mobile hydraulic lift is equipped with a protective device before the test, and liquidate the unnecessary objects on the equipment to ensure safety.
3. Try to run the (Windows) mobile hydraulic lift electrical part first. Do not hang up the belt or disconnect the coupling (Coupling); after confirming that the steering is correct, then hang the belt or connect the main unit and properly tension it.
4, mobile hydraulic (hydraulic) lift test should idle for 1 hour, pay attention to temperature changes. According to the assembly unit, one component, one unit and one unit, the system is run up step by step (Windows). If the previous level is unqualified, the next level of operation is not allowed.
5. After starting the mobile hydraulic lift button, it should be jogged several times to check the operation of each part, and then revolve, and gradually increase from low speed to high speed.
6. If there is any abnormality in the hydraulic hydraulic (revolve) test, the vehicle should be stopped for maintenance immediately. The hydraulic lift is mainly realized by the pressure transmission of hydraulic oil to realize the lifting function. Its shearing fork mechanical structure makes the lift hoist has high stability, wide working platform and high carrying capacity, which makes the working range higher. Large and suitable for multiple people working at the same time. It makes aerial work more efficient and safer.
7. In the mobile hydraulic lift test, the lubrication system (system) and the cooling or heating system are required to be unimpeded. The valve components and the organization are correct, flexible and reliable, and the components are free from cracks and damage. And other defects.
8. After the mobile hydraulic lift is finished, the power source is disconnected, the pressure and load are removed, the obstacles on the moving line are liquidated, and the operation record is sorted. Lifting freight elevators are mainly used for transportation of high-altitude goods in factory assembly lines, cargo warehouses, parking lots, terminals, buildings, logistics, etc. The lifting freight elevator lifting system is driven by a hydraulic pumping station, so it is also called a hydraulic lifting freight elevator.
9. Check the items of the factory inspection certificate of the mobile hydraulic lift carefully. The hydraulic lift is a lifting and lowering machine composed of a running mechanism, a hydraulic mechanism, an electric control mechanism and a supporting mechanism. The hydraulic oil is formed by the vane pump to a certain pressure. The oil filter, the explosion-proof electromagnetic reversing valve, the throttle valve, the hydraulic control check valve and the balance valve enter the lower end of the liquid cylinder, so that the piston of the liquid cylinder moves upward, lifting the weight. The oil returning from the upper end of the liquid cylinder is returned to the fuel tank through the explosion-proof electromagnetic reversing valve, and the rated pressure is adjusted through the overflow valve, and the pressure gauge reading value is observed through the pressure gauge. If there is any unqualified phenomenon, it should be promptly reported to the relevant departments, notify the manufacturer, and investigate the relevant responsibilities. Test certificate and record of returning equipment files.
