Abstract
Intended to be mounted on a backhoe 1, it incorporates a mechanism 2 for rolling up a chain 4 to whose free end is fixed the clam shell bucket (grab bucket) 5, a hydrocutter or any other perforating apparatus, the rolling mechanism 2 being embodied in the form of a planetary reducer actuated by hydraulic motors 3, and the chain 4 being structured on the basis of links joined in an articulated manner by means of transverse bolts or pins 6, such that said chain is prevented both from rocking laterally and from twisting, the hydraulic hoses 7 for supplying the perforating apparatus 5 passing alternately from one to the other face of the chain 4 via the opening defined between said articulation pins 6 between the links.
