Truck-mounted cranes
Boom truck & knuckle-boom crane repair
Stiff-boom and articulating cranes on trucks: National, Manitex, Terex, Altec, Palfinger, Hiab, Fassi, Effer.
A truck-mounted crane that won't work is a truck that can't earn. We repair telescopic boom trucks and knuckle-boom cranes where they sit — on the job site, in your yard, or on the shoulder. Booms, cylinders, slew bearings and rotation drives, outriggers, winches, hydraulics, and the electrical and remote systems that run them.

- Outriggers won't set, bleed down, or won't stow

- LMI, anti-two-block, or overload fault locking the crane out
- Hydraulic leak at a cylinder, rotary manifold, or valve bank
