Abstract

The invention concerns an arrangement for digging machines to be used for off-road driving, erecting telegraph poles, digging, for example, holes for posts and pillars, levelling and hewing work. On account of their low weight and small support surface underneath, small digging machines have a limited range of use. The invention solves this problem by means of a beam 2 which is pivoted on the fulcrum of the digging shovel 6 and can be coupled to the digging shovel 6 via a coupling arrangement 11. The beam 2 thus has a pattern of movement common to the digging shovel 6. The invention is used essentially on small digging machines, of the mini-digger type, but can of course also be used on large digging machines. <IMAGE>
