Selected model

Hydraulic Beaver · 48 lb breaker

Lighter breaker for slabs and screed

Overview

The Beaver is a portable hydraulic power pack: an engine driving a pump that sends steady hydraulic pressure down a hose to a tool. It is the power source, not the tool.

We rent it with a 48 lb breaker for slabs and screed, a 57 lb breaker for footings and rock, and a 23 ft hose pair so the pack can stand clear of the work.

The same pack runs hydraulic saws for cutting road surfaces, drills for boring tough material, pumps for draining flooded areas, and crimpers and spreaders for cable and pipe work.

Ask which tool the customer needs before anything else. The pack is chosen to feed it, and the hose length decides how far from the work it can sit.

Troubleshooting

Tool won't run

Checks to try, in order

  1. Move the flow control lever on the pack to ON.
  2. Push both hose couplers fully home — a half-connected coupler blocks flow.
  3. Run the engine at full throttle.

Reference draft — always follow the manufacturer’s manual.

Safety

  • Refuel with the engine off and cool, and run the pack outdoors only.
  • Wear hearing, eye and hand protection when breaking.

For hydraulic

  • Never disconnect hydraulic hoses under pressure. Shut down and relieve pressure first.
  • Never check for leaks with your hands — use cardboard. Hydraulic oil injection is a medical emergency.
