National Crane 1400A Boom Truck Service Manual

A National Crane 1400A is a telescopic boom crane mounted on a truck chassis. On a job site it sets steel, lifts HVAC units, places materials and handles general pick-and-carry work. When one goes down, the person under it is usually a rental fleet mechanic or shop technician trying to get it back on a job without waiting on a dealer.

What this manual helps you do

• Troubleshoot hydraulic system faults by following the diagnostic steps a service manual like this usually lays out.
• Remove and rebuild components on the boom and hoist, including disassembly and reassembly procedures.
• Adjust and test the outriggers and the turntable and slewing function after repairs.
• Trace electrical system problems using the schematics and test procedures you'd expect to find.
• Follow maintenance and adjustment procedures to bring a used crane up to a documented baseline.

Who this is for

A crane service technician or rental fleet mechanic doing repairs in-house on a 1400A. It also suits an independent repair shop or dealer technician who needs workshop-level procedures, and anyone with a used crane that arrived without paperwork.
