PURPOSE OF THIS GUIDE
This guide provides operating and maintenance information for operators of the Model RB2- 52A Roof Bolter. Maintenance and lubrication procedures are those normally performed by maintenance personnel. The techniques of roof bolting are beyond the scope of this guide and no such information is included. The guide is divided into three (3) sections:
SECTION 1 – GENERAL
This section contains general information about the roof bolter.
SECTION 2 – OPERATION
This section explains pre-operation, start-up, and basic operating procedures.
SECTION 3 – MAINTENANCE
This section explains the periodic maintenance procedures; it also includes lubrication requirements.
OPERATION – FAMILIARIZATION
In operation, the roof bolter is trammed to the bolting location from the relative safety of the tramming cab. When the intended location of the first row of bolt holes is reached, the operator and his assistant move to the front (cradle) controls. An “inch tram” control at the front of the machine, used in conjunction with the cradle swing controls, allows for accurate final positioning of the machine. Once the machine is properly positioned, the operators raise the “T” bar to the mine roof. They then lower the cradle stab foot to the mine floor and begin operating.
