The machine cannot come to a shop. So the shop comes to it.
Presses, balers, conveyors, lifts and fixed machinery with hydraulic circuits. When the equipment is bolted to a floor and bleeding fluid, the repair happens in place or it does not happen.

Fixed plant is a different animal from mobile equipment
An excavator with a hydraulic fault can be walked onto a trailer. A press bolted into a concrete floor with three-phase power and a pit under it cannot. That single difference changes the whole job. There is no option to take the machine somewhere better lit, so everything has to be diagnosed, repaired and tested where it stands, generally in a working building, often with production waiting on it.
Fixed plant also tends to run a duty cycle that mobile equipment never sees. A baler cycles the same stroke thousands of times a week. A conveyor’s hydraulic drive runs whole shifts without stopping. Components in that service wear in predictable places, and a cylinder that has done a million identical strokes fails differently from one on a machine that works a few hours a week.
If the machine in question drives on wheels or tracks, our mobile equipment hydraulic work is the page you want. This one is about the machinery that stays put.
Symptoms we get called forA cylinder creeping down under load, a machine cycling slower than it used to, fluid temperature climbing through a shift, a pump that has started whining, or a puddle nobody can trace to a source.
What you payA price before work starts, and no hourly minimum, so a hose made up and fitted is charged as exactly that.
Plants we visitShops, packing houses, recycling yards and production floors through Napa and Solano, plus regular calls into Contra Costa and Alameda. All the areas we cover.
Pressure loss is a process of elimination
A machine that has gone slow or weak gives you very little to go on from the outside. The pump could be worn and no longer moving its rated volume. A relief valve could be opening early and dumping flow back to tank. A directional valve could be leaking internally across its spool. A cylinder could be passing fluid past its piston seal, so the same oil goes back and forth and no work comes out. Every one of those looks identical from the operator’s seat.
The only honest way through it is to measure, and to measure at more than one point in the circuit. Pressure at the pump outlet tells you one thing. Pressure held at the cylinder under load tells you another. A cylinder that holds pressure with the valve centered but sinks when the circuit is live puts you in a different place than one that will not hold either way. The gauge narrows it down, then the part gets replaced because it was proven faulty, not because it was the most likely suspect.
This is where people lose money. Replacing a pump on a hunch is expensive, and when the actual problem was a relief valve out of adjustment, the new pump does not fix it. We would rather spend an extra half hour with gauges than have you buy a component that was never the fault.
The work an industrial circuit actually needs
These connect to each other. A pump that ran hot on degraded fluid has usually put wear debris through the valves downstream of it, and that debris is the next fault waiting to happen.
Hoses and fittings
Made up to length on site. Routing and clamping matter as much as the hose itself, because most failures start where a line was rubbing on something.
Cylinders
Seal kits, rod and bore inspection, and an honest answer about whether a scored barrel is worth rebuilding or replacing.
Pumps
Volume and pressure measured before anything is condemned, plus finding out what killed the last one so the replacement lasts.
Valves
Relief, directional and check valves. Contamination and internal leakage are the usual causes, and both are diagnosable in place.
Fluid and filtration
Oil that has gone dark, hot or wet is abrasive, and filters that were never changed are why several components fail at once.
Whole-machine diagnosis
When it is not clear whether the fault is hydraulic, electrical or mechanical, the diagnosis comes before the parts list.
Opening a circuit in a dirty building
Hydraulic systems fail from dirt more than from anything else. The clearances inside a pump or a valve spool are tiny, and particles you would never see on your hand are large enough to score them. In a clean workshop that is manageable. On a production floor with dust in the air, forklifts driving past and metal swarf on the ground, it takes deliberate effort.
So the routine is unglamorous and it does not get skipped. Shut the circuit down and relieve pressure, including anything stored in an accumulator. Clean the outside of the fittings before they come apart, because whatever is sitting on that fitting goes straight inside the moment it cracks open. Cap every port as it is opened. Keep new components bagged until the second they go on. Use fresh fluid from a sealed container, never whatever is left in an open drum in the corner.
The payoff is that the repair lasts. A cylinder resealed carefully in a dirty room is fine. The same job done casually puts grit into the new seals, and the machine is back down within months with the customer reasonably wondering what they paid for.
Show up when we say, tell you the number before we start, and do the job properly the first time.

What plant managers ask first
If something here is close to your situation but not quite it, call and describe the machine. That is faster than guessing.
Our press cycles slowly but nothing is leaking. What is that?
Usually internal leakage somewhere in the circuit. A worn pump no longer moves its rated volume, a relief valve can open earlier than it should and send flow back to tank, and a cylinder can pass fluid past its piston seal so oil moves without work getting done. None of those leak a drop onto the floor. Gauges at several points in the circuit are what separate them, and that is the first thing we do.
Can you actually repair this without taking the machine out?
That is the normal case for fixed plant, and it is what we are set up for. Hoses, fittings, cylinder seals, valves, filters and fluid are all work we do in your building. If a component genuinely has to come out for a bench rebuild, we remove it, get it done and refit it, so the machine stays where it is and only the part travels.
How do you keep dirt out of the system on a working floor?
By treating it as part of the job rather than an afterthought. The circuit is shut down and pressure relieved, fittings are cleaned before they are opened, ports get capped as soon as they are apart, new parts stay bagged until they go on, and fluid comes from a sealed container. Contamination is the leading cause of hydraulic failure, so skipping that routine just books the next breakdown.
Do you work on balers and conveyor systems?
Yes, both are common calls. Balers run a high-cycle life that is hard on cylinders and seals, and their circuits usually show it first. Conveyor hydraulic drives and tensioners fail differently, more often around pumps, motors and fluid condition. In either case the equipment is fixed in place, which is exactly the situation this work is built around.
Can the work happen outside production hours?
It usually should. We run around the clock, so nights, weekends and planned shutdowns are ordinary scheduling for us rather than a favor. For anything that needs the machine cold and still for a while, booking it into a shutdown window beats trying to squeeze it between runs, and the repair gets done properly instead of hurriedly.
How is the job priced?
You get one figure before work starts, covering the visit and the repair, with no hourly minimum attached. When a diagnosis has to come first, you hear what that costs, and then you hear the repair number once we know what is actually wrong. Nothing gets started on an open-ended basis and no number changes after the fact without you agreeing to it.
Tell us what the machine stopped doing.
The make, what the circuit drives, and what changed. Slower, weaker, hotter, noisier or leaking all point different directions, and that is usually enough to arrive with the right parts. One number, answered any hour.
