PAT Mark 4E/2 Load Moment Indicator Service Manual

The PAT Mark 4E/2 is a load moment indicator. It watches crane loading and warns the operator before the crane gets near its limit. When one acts up or a used crane arrives with no paperwork, the person with the wrench needs the workshop book. That's usually a rental fleet mechanic or an independent shop fixing it in-house.

What this manual helps you do

• Trace faults with the troubleshooting flow charts instead of swapping parts and hoping.
• Look up error codes and see what the system is telling you.
• Adjust the hardware using the basic adjustment procedures for the central unit.
• Check the mechanical and electrical layout of the central unit before you open it up.
• Follow the written procedures and drawings when you replace or reconnect components.

Who this is for

Crane service technicians, rental fleet mechanics and independent repair shops that work on cranes fitted with the Mark 4E/2. It's also useful for a dealer technician who needs the procedures at the bench.
