Aerial Ladder & Boom Service. The Big Truck Has to Be Right.
Hydraulics, outriggers, slides, rotation, waterway, and pre-inspection mechanical readiness for aerial ladders, platforms, and tower trucks.
Aerials don't tolerate guesswork. An outrigger that won't lock, a hydraulic creep in the boom, a waterway leak at the elbow — every one of these is a red-tag waiting to happen at your next annual NFPA 1911 inspection. We sort the mechanical and hydraulic side so the certifying agency only has to confirm what's already right.
Aerials don't tolerate shortcuts.
The mechanical side of an aerial is where shortcuts get people hurt. An outrigger that won't lock under load. A rotation bearing that's been worn long enough to develop play. A waterway that leaks under operating pressure. A slide that's running on a worn pad. We work the mechanical and hydraulic side — outrigger cylinders, slew bearings, rotation motors, slides, cables, pin work, and waterway integrity — so that when the NDT inspection happens the certifying agency is confirming what's already right.
Outrigger work.
Most aerial "won't operate" calls trace to outrigger faults — a pressure switch that won't see ground, a proximity sensor on the jack leg that lost its target, a 12V supply that corroded at the chassis ground, a hydraulic cylinder weeping enough to fail the interlock. We troubleshoot the whole circuit instead of replacing the obvious part and crossing fingers.
Brands.
Pierce, E-ONE, KME, Sutphen, Rosenbauer, Smeal, and the older Seagrave, Mack, and American LaFrance aerials still in service. Hydraulic systems: Parker, Eaton, Sun, and the OEM-specific manifolds. We don't do NDT structural inspections — that's specialized — but we get the truck mechanically ready for them.

Recent Fire Truck Repairs.
A representative slice of recent on-site work — the kind of failures that take an apparatus out of service and the kind of fixes that put it back in. Pump packing, DEF system faults, aerial hydraulics, multiplex electrical, brakes, charging systems, and everything in between.
Pump won't draft on the test pit
Rebuilt packing on a Hale Qmax mid-mount; pumped capacity at 150 PSI net pump pressure with paperwork.
Engine 4 — cranks but won't start
Cummins ISL fuel rail pressure fault; replaced high-pressure pump and primary filter; back in service by morning.
Aerial outrigger won't extend
Traced 12V supply fault to a corroded ground stud; replaced harness section; outrigger cycled and locked clean.
Tank-to-pump valve seized after mutual aid
Removed and serviced the Akron actuated valve; flushed debris; re-tested under draft.
Multiplex panel showing all faults
Class1 IO module replacement after a wet-environment fault; reprogrammed and tested every output.
Rear discharge gate leaking under pressure
Replaced seat and seal kit on a Waterous CSU two-and-a-half-inch gate; pressure tested to 250 PSI.
Engine derating mid-response
Detroit DD13 DEF system fault — failed quality sensor and clogged dosing valve; cleared and re-ran regen.
Air brakes won't release after sitting
Replaced moisture-fouled relay valve and added a desiccant cartridge to the air dryer; full system test.
Aerial rotation slow and creeping
Rebuilt rotation hydraulic motor and replaced worn slew bearing balls; tested full 360° rotation under load.
Scene lights flickering on the foreground
Charging system pulled down by a failed alternator and one weak battery in a four-bank string; replaced both.
