Let’s cut to the chase. If you work out in the field where there’s no power outlet, or you need to move hydraulic gear around all day, this portable power unit is exactly what you need. It’s basically a self-contained hydraulic system on wheels—engine/pump, oil tank, controls all in one small frame. Hook up your tool, start it up, and you’ve got instant hydraulic power wherever you need it. No cables, no generators, no hassle.
This thing is built for jobs where you can’t plug in. It’s light enough for one person to roll around, and it runs on gas, diesel or electric depending on the model. It just pumps out steady high-pressure oil to drive your tools, no fancy setup needed.

We’re Jinan Huachen Industrial, and we make these units to take a beating. No fancy fluff, just tough gear for real work sites.
The frame uses heavy-duty carbon steel where it counts, plus light aluminum for handles and covers. Strong enough to handle bumps, light enough to haul around. The pumps and valve blocks are forged alloy steel, heat-treated to stand up to constant pressure. Seals are premium fluorine rubber, oil and heat resistant, so leaks aren’t a problem.
Every part is machined tight, welded solid, then treated for rust. Before shipping, each unit runs flat-out for two full days, plus dust and water tests. We don’t send anything out that wouldn’t hold up in the field.
Municipal crews use the gas model for patching roads in old neighborhoods. It rolls through narrow streets, no power needed, and keeps the job moving fast.
Tunnel and mine crews love the diesel version. It runs steady all day in dusty, damp conditions, no complaints.
Local rescue teams go with the electric model. Quiet, no fumes, and it powers their cutters and spreaders when they need it most.
Q: Gas, diesel or electric — which one to pick?
A: If you’re out in the field with no power, gas or diesel works best. Gas is lighter and easier to start. Diesel runs longer on less fuel. Electric is quiet and clean for indoor or urban jobs.
Q: It’s leaking oil. What should I check first?
A: Most leaks come from loose fittings or worn seals. Tighten all connections first. If it still leaks, replace the seals. Keep the hydraulic oil clean to avoid wearing parts out early.
Q: How often do I change the hydraulic oil?
A: First change after 200 hours. Then every 500 hours under normal use. If you’re working in dust or heat, shorten that to 300 hours. Stick to standard 46# anti-wear oil.
Q: The unit runs, but pressure’s too low.
A: Check the oil level first. Then clean the filter. Next, adjust the relief valve to the rated pressure. If it’s still weak, you might need to check the pump for wear.
Q: What maintenance keeps it running longer?
A: Check oil and fuel every day before you start. Blow dust off the filter and cooler weekly. Change oil and filters on schedule. If you’re storing it, keep it dry and run it for a few minutes once a month to prevent rust.
