Product Description
CMM2-20 Hydraulic Bolting Rig for Coal Mine


I. General of CMM2-20 Bolting Rig


CMM2-20 Hydraulic bolting jumbo is a new supporting machinery for tunneling. Using with tunneling drill jumbo, it would work for high tunnel supporting, and improves present tunneling technics. The supporting height could be 3-4.5m, width could be 1.2-3.2m, and slopes could be ±15°.

CMM2-20 Hydraulic bolting jumbo has the following features in design:
Structure is reasonable, compact and good in rigidity. 
The jumbo adopts direct hydraulic control, and is easy operation and maintenance. 
Hydraulic motor drives travelling. Track tension use cylinder.
Small overall size improves transportation efficiency in underground mine.
Front supporting device with three-stage cylinder fully protects worker's safety.
This bolting jumbo features high efficiency, easy operation and maintenance, and reliable working. 
Executive standard:  Q/JQP02-2008  MT/T199-1996
                                                                                                                                                                                  

III. Working Environment Condition

Altitude is no more than 2000m;
Temperature is between -5ºC to +40ºC
Relative air humidity is no more than 95%(25ºC) 
Could work in the mine that contains gas and other explosive mixed gas.  
In the environment of no broken insulating gas or team.   
The place no continuous dripping.
