INSTRODUCTION: Bolts are combined to a integral reinforcement structure by the strap, the supporting capacity is highly improved, especially in fragmented roof bolting works.
MQT Series- Pneumatic Roof bolter
MQT series Pneumatic Roof bolters are designed for coalmining support. They have following advantages: improvingsupporting effect, reducing cost and labor, enhancing tunnelbuilding speed, easy to Transport.
The machine according to Company Standard:Q/TLBS-08-2005, MT/T688-1997
Function and character:MQT series Pneumatic Roof bolters with small Volume, lightweight, high torque, easy to operate and maintain, at the sametime, the machine put drilling, mixing, installing function intosame body, it’s ideal tools to work in all kind of drifts withhardness of F≤7.
