Mining pneumatic wrench with high torque

Description :

　　Structure and working principle of pneumatic wrench:

　　A pneumatic wrench is a high-speed impact handheld tool powered by compressed air. It mainly consists of three parts: valve section, engine section, and impact section. The engine rotor and impactor are directly connected by splines without deceleration, converting the rotational kinetic energy of the rotor into impact energy, thereby achieving rapid tightening or disassembly of nuts.

　　The use of pneumatic wrench

　　（1） U-shaped steel bracket

　　1. When installing a U-shaped steel bracket head-on, a mining pneumatic wrench can quickly tighten the cable nut to balance the force on the bracket, greatly reducing the labor intensity of workers and ensuring the quality of support.

　　2. Twist the cable nut: After the U-shaped steel bracket is erected, it is inevitable that the bracket will become loose due to blasting vibration and other reasons. A mining pneumatic wrench can be used for twisting.

　　3. When the U-shaped steel bracket is "withdrawn", due to the corrosion of the nut in the humid environment underground, it is difficult to disassemble. It can be easily removed with a BE 42 pneumatic wrench.

　　（2） Anchor bracket

　　1. Tighten the anchor bolt nut: Install the tray and nut, put on the wrench sleeve, and start the gas for 2-5 seconds to reach the corresponding torque.

　　2. Mixing of cement and resin anchor rods: First, tighten the nut on the anchor rod, and use the anchor rod to push the medicine roll into the top of the hole. Start the air and crush the medicine roll.

　　（3） This pneumatic wrench is safe and explosion-proof, suitable for loading and unloading nuts in places with explosion-proof requirements above and below wells.
