Drywall cranes, built, sold, serviced and repaired
We put PM drywall cranes on trucks, keep them running, and stock the parts for every other make as well. Four story, five story, six story, top seat, joystick or radio remote.

What we do
Robert's Diesel Works has been building and repairing cranes in Orlando since 1989. Most of what leaves the shop is a drywall crane on a truck: you pick the chassis, you pick the crane, you pick the options, and we build the combination. The rest of the week is parts and repair for whatever rolls through the gate.

Service, repair and fabrication
We service and repair cranes and the trucks under them: engines, brakes, transmissions, differentials, transfer cases, hydraulics, automatic greasing systems, top seats, rear ends and tag axles. The fabrication shop builds what nobody sells: sub-frames, decks, pole bodies, oil field cranes and one-off machines.
