Abstract (en)
[origin: WO8501536A1] A drilling machine includes a coupling means (19) for removably coupling the drilling machine (1) to the bucket of an excavator with the aid of gripping arms (20, 21). Between the drilling machine and coupling means there is a rubber member (9) taking up misalignment stresses and a gas spring (11, 12) taking up shock and compression stresses arising in conjunction with drilling.
