A mechanical jack is a type of manual lifting equipment designed for heavy-duty applications. Its compact and efficient design allows it to utilize the motion of a lever (rocker) to rotate a pinion, which in turn drives a pair of conical gears. These gears then rotate a screw, pushing the lifting sleeve upward or downward to raise or lower the load. This mechanism ensures smooth and controlled lifting, making it a reliable tool for various industrial and mechanical tasks.
When using a mechanical jack, there are several important precautions to keep in mind:
1. Always maintain the cleanliness of the machine's surface and regularly inspect its internal components. Ensure that the pinion inside the rocker moves smoothly and reliably, and that the lifting sleeve operates freely without resistance.
2. The contact surfaces between the lifting sleeve and the housing should be lubricated as needed. Additionally, all oiling points should be regularly greased to ensure proper function and extend the life of the equipment.
3. For safety, never overload the jack. Avoid using it when it is damaged or malfunctioning. It is also not recommended to use it for multiple consecutive lifts without proper rest, as this can lead to failure or accidents.
