Komatsu 150A, 150FA Crane Operation and Maintenance Manual (CEADC20081)

On these Komatsu 150A / 150FA cranes, you’re usually lifting heavy structure or plant gear on construction and industrial sites, often in tight, uneven areas. This Operation and Maintenance Manual is what I keep handy to set up the crane correctly, stick to a sane service rhythm, and keep it safe and predictable under load. If, for example, the boom motions start feeling jerky or the crane doesn’t feel stable on outriggers, I’d use this book to trace through the basic checks, verify setup, and decide if it’s a simple adjustment or if we park it for deeper repair.

Applications & Use Cases

Plan preventive maintenance so inspections, greasing, and filter changes get done before anything fails on a lift.
Verify correct setup of outriggers and superstructure alignment to keep the crane stable on different ground conditions.
Trace early wear signs like slow hoist speed or odd noises back to likely components before they turn into downtime.
Guide daily walk‑around inspections so operators don’t miss cracks, leaks, or loose hardware.
Support training of new operators on proper operating habits that reduce stress on the crane over time.

FAQ

Q: Can I use this manual on a tablet in the field?

A: Yes, it’s practical to keep a digital copy on a tablet or laptop so you can zoom diagrams and search terms while standing at the crane.

Q: Is it worth printing parts of this manual?

A: I’d print the safety, setup, and routine inspection pages and keep them in a binder in the cab for quick reference during shifts.

Safety Note

Always follow the manual’s safety procedures and lockout steps before inspecting, adjusting, or working under any part of the crane.
