Ram Dozer Press Applications

Pacific’s Straight Side Hydraulic Presses employ either a single or double cylinder six-point, non-metallic adjustable gibbing, with flange mounted piston and slide connections. All hydraulic presses are heavy plate steel and/or column construction, have large bed areas and generous open heights, and provide full tonnage throughout the stroke (up to 2000 tons), providing multiple job versatility and precision tool alignment.

Hydraulic Ramdozer Presses

Straightening out your bar, shaft and/or plate applications

Multi-application versatility meets your heavier straightening /fabrication applications

Hydraulic Ramdozer Press for Straightening bar, shaft or plate applications -- from Pacific Press Technologies.Require straightening of bar, shaft or plate work? Needing a versatile shop tool that allows you perform bar/angle/channel cut-off, rail and structural contouring and straightening, or other applications where powerful long strokes in a horizontal configuration is required? Pacific's Hydraulic Ramdozer can fulfill the needs of a multitude of applications and industries…and do so in an affordable package.

Jobs with horizontal positioning of parts/materials requiring increased open heights are suited to the Ramdozer. Material handling costs and strain on manpower alone justifies the Ramdozer's ROI. It's recognized as a plate straightening workhorse due to its vertical material handling orientation (via crane in most cases) and the system's precision press control. Long, full power throughout the stroke can be adjusted to meet your application's tonnage and pressing speeds. Up to eight foot wide plate can be straightened.

Choose from 100 to 500 ton standard models (seven different standard sizes). In addition to the Ramdozer, check out our gib-guided hydraulic Bulldozer for increased job processing versatility, especially jobs needing extra precision.

Standard Features:

Consider these key machine features/user benefits…

  • Rugged Construction: Rolled plate construction is rigid and trouble-free operation to the frame and hydraulic packings. Dies are easily mountable to the end lugs because T-slots are machined longitudinally in the cross head.
  • State-Of-The-Art Hydraulic System: Precision, high-speed performance and dependability all start with Pacific-built heavy-duty stacked valve system. Built-in hydraulic overload protection protects against overload and jamming. Single piece cast cylinders and cast piston/rod assembly eliminate high stresses, oil leakage and delivers trouble-free operation.
  • Superior Controllability: Full-rated tonnage and generous bed lengths deliver power throughout a long stroke. Stroke/speed adjustments (rapid advance and slower pressing speeds, all adjustable via a cam and switch that alters the position of speed change at will) permit fast set-ups. Moveable foot switch enables "at-the-work eye-sighting".
  • Laser Bend Alignment: Two laser line generators — one at each end of the tandem system - project a visible line at the centerline of the installed tooling. A blank with the bend lines marked is moved into the press brake until the mark and the visible laser line are aligned and the press brake is cycled to accurately complete the bend. An optional center mount (removable) laser line generator is available when a single press brake of the tandem system is to be used.
