In mining production, mechanical equipment operates at high intensity for a long time, resulting in frequent malfunctions. Spiral jacks play an important role as a critical maintenance aid tool.

I remember one time, a large crusher in the mine had a serious malfunction. After inspection, it was found that the transmission components at the bottom were severely worn and needed to be replaced. However, the crusher is bulky and heavy, making it impossible for maintenance personnel to directly operate the bottom. At this point, the screw jack came in handy. The maintenance personnel placed the screw jack on a specific support point of the crusher, and by rotating the screw, the jack slowly lifted one end of the crusher, exposing the bottom transmission components. During this process, the screw jack, with its stable support force, keeps the crusher steadily lifted, allowing maintenance personnel to safely and conveniently inspect, remove, and replace worn parts.

Once again, the internal drum of the ore conveyor belt malfunctioned. The screw jack lifts the body of the conveyor, creating enough operating space for maintenance personnel to smoothly enter the interior to repair the drum.

Spiral jacks, with their simple and reliable working principle, have helped mining maintenance personnel overcome many difficulties, greatly improving maintenance efficiency, ensuring the normal operation of mining machinery and equipment, and providing strong support for the smooth progress of mining production.
