Boom truck and knuckle-boom crane repair
For telescopic and articulating cranes on trucks: booms, outriggers, rotation and the PTO that powers them.
Questions about symptoms
The PTO light is on but nothing moves. Where do we start?
Write down what you see: whether the PTO engaged, whether you hear the pump, and whether any function moves at idle or at higher RPM. Share the make, model and any fault codes so we can ask the right follow-up questions.
Why does the boom only work at high idle?
That often points to a supply or pump-drive problem, but other issues can look the same. Note whether every hydraulic function is slow or only the boom, and whether it started suddenly or got worse over time.
Outriggers won't set or won't release.
That can be a valve, hose, cylinder or control issue. Note whether you hear the pump, whether one side is affected or both, and whether the crane functions still work.
The remote works sometimes.
Intermittent remote problems can be the transmitter, receiver, wiring or a weak battery. Tell us whether the truck-side controls work when the remote does not.
