Boom Truck Repair
A boom truck is a truck chassis, a PTO, a hydraulic pump, a boom and a set of outriggers that all have to cooperate. When the boom is slow, the fault might be at the transmission-mounted PTO, the pump, the control valve or an interlock that thinks the outriggers aren't down. Mondak repairs boom trucks as one system, so you don't get the truck fixed at one shop and the boom at another. Common work includes PTO engagement problems, low pump output, boom control faults, outrigger issues, leaking cylinders and electrical interlocks, plus the regular chassis repair the truck needs.

THE MONDAK APPROACH
Diagnose first. Repair with purpose.
We work from the power source outward: confirm the PTO is engaging and turning the pump, measure pump output, then check the control valve and interlocks. That order avoids replacing a boom valve when the actual problem is a worn PTO shift linkage.
Interlock switches, hoses and control issues can often be handled where the truck is parked. PTO replacement and pump work are done at the Glendive shop.
