ABSTRACT:
A machine for use in mining or tunnelling has a chassis supporting a mobile arm provided with rotary cutters. A shovel beneath the arm serves to transfer material onto a pair of conveyors mounted alongside the machine chassis. This shovel is supported for vertical pivoting displacement on a beam which is itself linked via a central pivot joint to the machine chassis. Piston and cylinder units effect tilting and vertical adjustment in the shovel position.
