The self weight gripper has the following applications in the mining industry:
1. Drilling operation:
     Stable drill rod: In geological core drilling and coring construction, the self weight gripper is an indispensable tool for the hole opening. In the exploration and drilling process of mineral resources such as coal mines, when the drill rod penetrates deep into the ground, the self weight of the drill rod will cause the slip and elliptical head of the self weight clamp to move downward, thereby tightly clamping the drill rod, preventing the drill rod from shaking and displacement during the drilling process, ensuring the accuracy and stability of drilling, and helping to obtain correct geological information
     Auxiliary drill rod connection and disassembly: During the loading and unloading of drill rods, the self weight clamp can achieve the docking, detachment, and disassembly of drill bits between drill rods. When in use, it can effectively clamp the drilling tools in the well, prevent them from slipping, ensure the safety and efficiency of the drill pipe connection and disassembly process, and thus improve drilling efficiency and safety
2. Ore handling and loading/unloading: In mining, self weight clamps can be applied to equipment such as ore loaders for ore handling and loading/unloading. When the loader grabs ore, the self weight gripper can use its own weight to generate sufficient clamping force, firmly grasp the ore, and then load it into the transport vehicle, improving the efficiency of ore handling and reducing the scattering of ore during the handling process.
3. Maintenance and repair of mining equipment: When maintaining and repairing some large mining equipment, it is necessary to disassemble and install the components of the equipment. Self weight clamps can be used to clamp these components, such as large gears, shaft parts, etc., to facilitate maintenance personnel's operation, improve maintenance efficiency and quality, and ensure the normal operation of mining equipment.
