(1) Before application, careful inspection should be carried out to ensure that the anchor bolts are tightened, that there are no leaks in components, pipelines, etc., and that the wiring is not loose or damaged.
(2) When carrying out the elevator on the lifting platform, the four legs should be well supported and the support points should be sturdy.
(3) After starting the motor, conduct a full load test run first and deliver it for use only if there are no problems.
(4) If the working temperature is less than 10 ℃, then the deep well pump should be run for 3 to 5 minutes first. If there are no problems with the gasoline pump, electric lifting platforms can be used at the beginning to prevent any problems.
(5) When working on the electric lifting platform, the staff should try to be in the management center of the work platform as much as possible, and take safety precautions to prevent risks.
(6) This device prohibits overweight applications and their super characteristic applications.
(7) When the hydraulic lifting platform of the hydraulic press is in the raising and lowering position, the staff on the service platform cannot move the parts to prevent risks.
(8) Once an abnormality occurs, the switch power supply should be immediately disconnected (cut off; cut off), and then technical maintenance and repair personnel should carry out repairs. Other personnel cannot handle it on their own (ch ǔ l ǐ). Basic principle of lifting platform: Gear oil is generated by an axial piston pump with a certain working pressure. It enters the lower part of the hydraulic cylinder through an oil filter, a explosion-proof electromagnetic directional valve, an overflow valve, a hydraulic control check valve, and a static balance valve, causing the piston rod of the hydraulic cylinder to move upwards and lift the suspended object. The oil returned from above the hydraulic cylinder returns to the car's fuel tank through a explosion-proof electromagnetic directional valve. Its rated working pressure is adjusted according to the speed control valve, and the reading value of the pressure gauge is observed based on the pressure gauge.
The piston rod of the hydraulic cylinder moves downwards for fitness (i.e. lifting objects). The gear oil enters the upper part of the hydraulic cylinder through the explosion-proof electromagnetic directional valve, and the return oil below the hydraulic cylinder returns to the car fuel tank through the static balance valve, hydraulic control check valve, overflow valve, and explosion-proof electromagnetic directional valve. To ensure stable descent of the suspended object, the braking system can be trusted. A static balance valve is installed on the return oil passage to balance the control circuit and maintain the working pressure, so that the descent rate will not be affected by the suspended object. The total flow rate is adjusted by the overflow valve to operate the elevator speed.
