  • Combination cab and canopy for mine roof bolting machine
    Patent number: 4173371
    Abstract: A cab which functions as a protective canopy for the operator of a roof bolting machine. The cab/canopy is mounted to the roof bolter in such a fashion so as to permit the operator to both tram and drill roof bolt holes from the same position while being protected from roof falls. Further, the cab/canopy is mounted upon the front of the machine in an articulated manner such that the cab and machine are relatively vertically movable. In this manner, the operator may control the machine with greater surety.
