摘要

Mechanical-hydraulic machine for dredging of ports, rivers, swamp channels, lakes and beaches at great depth, in which a mobile chassis (1) is established on the ground, from which a main and tilting arm emerges (2), topped with a rocker arm (5), tilting with the collaboration of a cylinder (6), analogous to a conventional backhoe machine, characterized in that it incorporates a set of pulleys (7) mounted freely on the free end of the rocker arm (5) of rotation, for the passage of cables (8) to suspend a working tool (9, 9``), as well as for the passage of hoses (10) that supply pressure to said tool (9, 9''), the said cables (3) supplied by at least one winch (11) provided with at least one pair of drums (12), while the hoses (10) are themselves supplied by at least one pair of casings (16) also materialized on reels for the winding/development of said hoses .
