Abstract (en)
[origin: EP1077306A2] The mobile mining work apparatus has a movement mechanism frame (10) and a work intermediary arm (18) along which a boring, ramming or similar tool can move. The movement frame has a chain running mechanism (12) which supports a rotatable upper carriage (14). The work intermediary arm is supported by the movement frame via a support mechanism (16). The support mechanism has two spaced apart support guides (20,24), the first ends of which are connected via first spaced rotary bearings (22,26) with the movement frame and their second ends via second spaced rotary bearings (30,32) with an intermediate guide (34). The intermediate guide, via a third rotary bearing (50), is connected with the work intermediary arm and via a fourth rotary bearing (52) supports a neck support arrangement (54), which with its free end, via a fifth rotary bearing (56) engages on the work intermediary arm.
