Different support engineering should choose different types of bolt rig

Bolting Roof Bolter is the key equipment of construction, affecting their quality support and supporting the pace. Different support engineering should choose different types of bolt rig, bolt rig currently made ​​form of a single, mostly split, torque is small, the body bulky and inconvenient, and foreign imports, although Roofbolter  power transformers  and performance , but the price is expensive. With electric hydraulic technology in the field of  Voltage stabilizer  machinery applications, research a new multi-purpose hydraulic bolt rig, able to adapt to a variety of geotechnical engineering construction needs anchoring, with full hydraulic crawler, high torque.
