The mechanical jack is a type of manual lifting equipment widely used in industrial and construction settings. Its compact design allows for efficient operation by utilizing the motion of a rocker arm to turn a pinion gear. This mechanism is driven by a pair of conical gears, which in turn rotate a screw to push the lifting sleeve up or down, enabling the lifting or lowering of heavy loads. Due to its simple yet effective structure, it remains a reliable choice for many applications.
When using a mechanical jack, it's important to follow certain safety and maintenance guidelines. First, always keep the machine’s surface clean and regularly inspect its internal components. Ensure that the pinion in the rocker moves smoothly and that the lifting sleeve operates freely without resistance. Second, lubrication is essential—keep the contact surfaces between the lifting sleeve and housing well-oiled at all times, and make sure other oiling points are properly maintained. Third, never overload the jack or use it when it’s not in good condition. Avoid repeated or excessive use, as this can lead to failure and potential hazards.
