The front card jack is a commonly used hydraulic lifting tool, mainly used to support and lift heavy objects, suitable for construction, bridges, tunnels, culverts, water conservancy and other engineering projects.
How to use:
1. Before use, check the integrity of the jack to ensure that there is no damage or leakage.
2. Place the jack on a stable support to ensure its stability.
3. Use a hydraulic pump to inject hydraulic oil into the jack to raise it, and place the heavy object on the support plate of the jack.
4. When the jack rises to the required height, stop injecting hydraulic oil. If it needs to be lowered, open the return oil valve of the jack to return the hydraulic oil to the tank.
5. When the heavy object is suspended in the air, it is forbidden to move the jack to prevent accidents.
6. During the operation, the working status of the jack should be observed at any time. If any abnormality is found, it should be stopped and handled immediately.
7. After use, lower the jack, put it back in place, and pack up the tools.
