Abstract: A hydraulic cylinder (1) which acts as a cylinder hollow rod in an outer hydraulic cylinder (10) is disclosed comprising an inner rod (4) with a piston (2) and piston-gland (3) wherein the cylinder hollow rod (1) is held longitudinally displaceably in the cylinder housing (10). The system additionally has a cylinder base (5) and a fibre cover (14) on the outer casing of hydraulic cylinder (10). The system also has ports for fluid (11, 12 and 13) corresponding to four chambers, (67, 8 and 9 respectively). According to the invention, when pressure is applied to chamber (7), the internal rod (4) extends into the chamber (6), displacing its mass and dramatically increases the pressure in Chamber (6). This displacement is effectively an internal pump which can be activated multiple times within a given stroke of rod (1).

Abstract: A bucket (10) that is attachable to a piece of earth moving equipment by means of transverse shafts (11). The bucket (10) includes an outer casing (12) providing an upper (first) jaw member (13) and a lower (second) jaw member (14) so as to generally encompass a passage (15) along which material to be crushed passes from a passage inlet (16) to a passage outlet (17). Preferably the jaw member (13) includes an attachment assembly (42) that provides for attachment of the bucket (10) via shaft (35) to the piece of moving equipment that is to use the bucket (10).
