National Crane N80A Articulating Crane Service Manual

A National Crane N80A is an articulating knuckle-boom crane that mounts on a truck or base and folds down for transport. It sits on a job site lifting and placing loads, then stows when the truck moves on. When one goes down, the person who reaches for the service manual is usually a fleet mechanic trying to get it fixed in the shop instead of waiting on an outside call. That's where this document earns its place.

What this manual helps you do

• Troubleshoot hydraulic system faults by working through the symptoms in order instead of swapping parts.
• Adjust the controls and safety system so the crane behaves the way it should after a repair.
• Replace worn components in the boom and extensions, and in the stabilizers, with a defined procedure to follow.
• Check the electrical system when a function stops responding.
• Follow maintenance and adjustment steps to keep the unit documented and on a schedule.

Who this is for

A rental fleet mechanic or crane service technician who maintains N80A units in-house. It also suits an independent repair shop that takes in a used crane with no paperwork and needs something to work from.
