[0003] The linear push type jacking device is a mechanical device that uses linear motion mechanisms to achieve jacking functions. Its core is to convert the rotational motion or electrical energy of the power source directly into linear motion through linear motion components such as air cylinders, hydraulic cylinders, electric push rods, and screw nut mechanisms, thereby pushing the jacked objects to rise or fall vertically. The jacking device has the advantages of large lifting capacity, unlimited lifting height, arbitrary combination, simple structure, easy installation and maintenance, and use in narrow environments, and is widely used in various occasions that require lifting or moving heavy objects, such as stages, factories, and ports.

The stone ball may roll or slide due to external forces, which not only causes serious harm to the operator but also may damage the surrounding equipment and environment. In order to prevent the stone ball from rolling or sliding, the lifting speed needs to be further reduced to stabilize the stone ball, increasing the complexity of operation and reducing work efficiency.
