Electric Cable Bolt Tensioner
The Electric Cable Bolt Tensioner is a high-efficiency installation tool for coal mine roadways.
High-Speed Tensioning With Explosion-Proof Motor
The Electric Cable Bolt Tensioner is a high-efficiency installation tool for coal mine roadways. It applies pre-tightening force to anchor cables quickly and safely. This product is equipped with a special explosion-proof motor for underground use. The motor meets the EXdl Mb explosion-proof rating, which is the highest standard for Chinese coal mines. The device includes a tension jack, a DYB-3.0/63 electric pump, and high-pressure hoses. Once connected to power, the pump runs automatically. The jack grips, tensions, locks, and releases the cable in a smooth sequence. For mines with stable power supply, this product delivers the fastest tensioning speed.
Large Flow Rate Saves Time and Labor
Our DYB-3.0/63 electric pump has a rated flow of 3.0 liters per minute. This is twice the flow of a pneumatic pump and many times faster than a manual pump. The pressure builds up very quickly. With this Electric Cable Bolt Tensioner, you can cut tensioning time by more than half. In one shift, your team can install many more anchor cables. For large mines where advance speed is critical, this efficiency directly translates to productivity. The jack also uses aerospace-grade materials and processes. The MD22-400/63 jack weighs only 20 kg. This makes the product easy for workers to handle and position.
