Boom Lift Repair

Boom Lift Repair in Central Iowa

A boom lift puts a person sixty feet in the air and trusts a few hydraulic cylinders and hoses to keep them there. When one of those parts starts to leak, you don’t get to ignore it. Ames Hydraulics does boom lift repair for the utility crews, tree services, sign companies, and contractors around Ames and Central Iowa who run articulating and telescopic manlifts every day. We work the hydraulics and structure that raise the boom, level the basket, swing the turntable, and feed oil all the way up the boom — the parts that fail on an aerial lift and the parts that have to be right.

Boom lifts carry more cylinders than almost anything we touch. There’s the main lift cylinder that raises the boom, the telescope cylinder that extends it, a leveling cylinder under the basket that keeps the platform flat as the boom moves, and the hydraulics that rotate the turntable. Tie all that together with long hose runs that travel the length of the boom, and there’s a lot that can wear. When a cylinder seal bypasses, the boom drifts down or the basket tilts; when a hose chafes through up on the boom, you lose a function and dump oil. Sorting out which one is the trouble is the first job in any boom lift repair.

The Boom Lift Hydraulic Repairs We Do

• Boom and telescope cylinder rebuilds. When the boom settles on its own or won’t hold extension, worn cylinder seals are the cause. We rebuild the cylinder, inspect the rod and bore, and pressure test it before it goes back up.
• Basket leveling cylinder service. The small cylinder under the platform keeps the basket level through the boom’s travel. When it leaks, the platform tilts — a safety problem we reseal and test.
• Turntable rotation hydraulics. Slow, jerky, or weak swing points to the rotation drive, its motor, or the supply hoses. We diagnose and repair the rotation circuit.
• Hose runs up the boom. Hoses that travel the boom flex and chafe at every joint. We build and route new assemblies, rated for working pressure and clamped so they don’t rub through.
• Structural welding. Cracked boom sections, worn pivot bushings, and damaged baskets get repaired at our bench through our welding and fabrication shop.

Why Boom Lifts and Manlifts Fail

An aerial lift fails for reasons that trace back to where it works. Boom lifts sit outdoors in all weather, so seals harden and fluid takes on moisture. The long hose runs up the boom flex through thousands of cycles and slowly chafe against the structure unless they’re clamped right. And contaminated hydraulic fluid — dirt and water working into the oil — is one of the biggest causes of cylinder and valve wear on these machines. Because the failure is usually internal, a manlift can look fine and still drift the boom or tilt the basket. That’s why every boom lift repair we do ends with a holding and function test, not just a reseal.

We service the range that turns up on Central Iowa job sites — towable boom lifts, self-propelled articulating units, and telescopic stick booms. We lead with the hydraulic and structural work because that’s what keeps a worker safe at height, and it’s the work our shop is built around. When we rebuild a cylinder off a boom, we hone the bore, inspect the rod for scoring, and hold it under pressure on the bench, because the only acceptable result on a machine that lifts people is one that holds every time.

Built for the Crews Who Work at Height

Our boom lift repair customers can’t put a worker up on a machine they don’t trust. A line crew, tree service, or sign company with a manlift down loses the whole crew’s day, not just the machine. We give you a straight price before we start, turn jobs around fast, and pressure test every cylinder we rebuild before it ships. If you can’t move the unit, we offer free pickup and delivery within 60 miles of Ames.

As a full hydraulic shop, we handle the rest of your fleet too. The crews who run boom lifts usually run a scissor lift for lower work and a bucket truck for the road — we fix those cylinders, hoses, and pumps under the same roof.

Get Your Manlift Back in the Air

If the boom drifts, the basket won’t stay level, the swing is weak, or a hose is weeping up on the boom, those are exactly the hydraulic faults we fix.
