National Crane N135 Articulating Crane Service Manual

A National Crane N135 is a knuckle-boom crane that rides on a truck or base and folds down for transport. On a job site it sets loads, reaches over obstacles and then tucks away so the truck can move on. When one gets sluggish, leaks, or quits working, the person with the wrench needs the workshop book open next to them. That's what this manual is for.

What this manual helps you do

• Troubleshoot slow, weak or drifting boom movement in the hydraulic system.
• Follow removal and installation steps when you're replacing a component on the boom and extensions.
• Check and adjust settings in the controls and safety system after repairs.
• Trace electrical faults through the electrical system instead of guessing at wiring.
• Verify the slewing system and stabilizers work properly before the crane goes back to work.

Who this is for

A crane service technician, rental fleet mechanic or independent repair shop working on an N135 out of warranty. It also suits anyone who has picked up a used crane with no paperwork and needs to know how it goes together and how it's maintained.
