National Crane 900H Boom Truck Service Manual

A National Crane 900H is a telescoping boom crane mounted on a truck chassis. It sets up on a job site, lifts material to height, and drives to the next one. When it's out of warranty or arrives with no paperwork, the person under it needs a workshop document. This manual is written for that person, whether the job is a tired hydraulic circuit or a stubborn electrical fault.

What this manual helps you do

• Troubleshoot hydraulic system problems by working through the fault procedures before you replace parts.
• Remove and rebuild components on the boom and hoist, then reassemble them in the right order.
• Adjust and test the outriggers and the turntable and slewing assembly after repair.
• Trace electrical system faults with the manual's wiring and test procedures beside you.
• Follow the maintenance and adjustment procedures to set the crane up correctly after a repair.

Who this is for

If you're a crane service technician, a rental fleet mechanic or an independent repair shop doing 900H work in-house, this is the book to have open on the bench. It also suits a dealer technician who picks up a used crane with no documentation.
