 Pacific Press Technologies

Hydraulic Bulldozer Press for bending long or heavy structural shapes.The tool for bending long and/or heavy structural shapes

Specific applications demand specialized machine tools…especially true in the world of long part and/or heavy plate fabrication work. Pacific's Hydraulic Bulldozer design has been a heavy industry mainstay…in product design…in heavy tonnage performance…in overall productivity. But what else would you expect from North America's hydraulic bending technology leader for more than fifty years?

A low-silhouette design makes it easy to move and position large parts over the press. Long, full power throughout the stroke can be adjusted to meet your application's tonnage and pressing speeds.

Choose from 100-500 ton standard models (seven different standard sizes). In addition to the Bulldozer, check out our Ramdozer.

Standard Features:

Consider these key machine features/user benefits…

  • Rugged Construction: Rolled plate construction is rigid and trouble-free. Heavy cast iron gibbing and hardened steel slideways assure rigidity and proper alignment. End lug is designed with a heavy metal interlock to absorb and better distribute loads throughout the frame. Die is easily mountable to the end lug 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: Gain increased levels of production, versatility and safety. Enjoy full-rated tonnage throughout the long stroke. Mode selector switch for ram inching control, two speed approach (rapid advance and normal press) or single speed approach (normal press) makes set up fast and easy. Fully-adjustable depth stop/back travel stop provides for instant change of ram open/closed dimensions. End lug operates from three different positions. Moveable footswitch enables "at-the-work eye-sighting" for straightening or bending operations.
