Abstract

An excavator 1 has a boom 14 which is composed of three arm pieces 15 to 17 which are each pivotable individually by means of an allocated piston/cylinder unit 23 to 25. The centre piston/cylinder unit 24 runs virtually completely within the centre arm piece 16 and in this way is largely protected from damage due to striking an obstacle. <IMAGE>
