The ram is reciprocably moved by the piston rod of a double-acting hydraulic cylinder. The rod is detachably connected to the ram by a simple yoke and cross pin arrangement and the cylinder is detachably fitted onto the beam by a trunnion pin that extends from the cylinder and slips into brackets carried by the beam for ready assembly and disassembly. An engine-driven pump assembly is connected to the cylinder by two detachable hoses and provides the hydraulic pressure for the cylinder.
