Push Rams are quickly installed on the Hevi-Haul HM-50 Bi-Directional Skates without any modification or welding for X axis or Y axis moves. A 3" Bore, 3' Stroke hydraulic cylinder attaches directly to the Skate by means of a U-bracket that is placed around it and secured with a bolted backbar. The Beam Clamp features an adjustable hydraulic clamping system that adjusts to fit 12" to 14" beams. Two 2-1/8" stroke 10,000 PSI clamp cylinders allow the Push Ram to be quickly and easily hydraulically clamped, extended, then unclamped and returned for the next extension. Cam rollers may be installed to hold the beam clamp on the underside of a beam. 195 lbs. Other ram sizes are available upon request.
