Gas Hydraulic Power Packs
Hydraulic power packs make handheld hydraulic tools portable. A self-contained pump unit pushes oil down a hose pair, and the tool on the other end works with no compressor, no generator, and no excavator behind it — which is how a crew breaks concrete inside an occupied building, cores a wall in a live plant, or splits rock where blasting is out of the question. This section covers the power packs themselves; the tools they feed sit alongside them in construction tools — hydraulic paving breakers, pick hammers and spike drivers, core drills, cut-off saws, and concrete and rock splitters. Ships from Denver.
Power Packs
The power pack listings cover the portable units themselves, in engine-driven and electric versions and in single- and twin-outlet form, from Atlas Copco, Chicago Pneumatic, Darda, and Tehma. That is where flow, pressure, and drive type are listed model by model, and it is the page to start on if you already know which tool the pack has to feed.
What Runs Off a Pack
Hydraulic tools trade the compressor for a hose pair. On demolition that means a breaker plus a crusher or metal shear. On fence, sign, and guardrail work it means a hydraulic post driver and a matching post puller. Underground it means hydraulic drills and the rest of rock drilling and splitting. For boom-mounted work the carrier supplies the oil instead — see excavator hydraulic breakers.
Matching a Pack to a Tool
Start from the tool, not the pack. Every hydraulic tool has a rated flow and a working pressure, and the pack has to meet both with a little headroom, through a hose pair sized and coupled to match. Get it wrong and the tool either runs slow or runs hot. Each product page lists what the tool needs, and the counter will confirm a pairing before you order.
Why Hydraulic Instead of Air
Hydraulic tools are compact, quiet, and low-vibration for the power they put out. They emit nothing at the tool, so they work indoors and underground, and their closed circuits keep dirt and moisture out of the moving parts, which means less wear and less maintenance. The trade is that you carry a pack and hoses rather than dragging air line back to an air compressor.
Common Questions
What is a hydraulic power pack? A portable unit combining a prime mover, a hydraulic pump, an oil reservoir, and filtration on one frame, feeding a handheld tool through high- and low-pressure hoses. It stands in for the excavator or shop hydraulics the tool would otherwise need.
Are hydraulic power tools genuinely portable? Yes, within reason. The packs are built to be wheeled or two-man lifted and to fit in a service van, and the tool end is no heavier than the pneumatic equivalent. You move a pack and hoses instead of a compressor and an air line.
Can a power pack replace an excavator breaker? For handheld-scale work, yes — that is the point of the tools in demolition and digging. For sustained production breaking on a carrier you still want a mounted unit; see excavator attachments.
Do you carry hydraulic hose and couplings? Yes. Hoses, quick couplings, wedges, and grease for Darda and Tehma tools sit in rock splitter and crusher accessories, with general hose, oil and lube alongside.
