PAT EI 65 1999 Operators Manual – OEM Load Indicator Specs

If you’re running a crane with a PAT EI 65 1999 Operators Manual load indicator, you already know that a misread angle or radius can kill. I’ve seen guys trust a faded sticker over the factory manual and nearly drop a boom. This is the genuine 1999 Operators Manual from PAT – 43 pages of operator and calibration instructions. It’s not a reprint. It’s the real deal for Link-Belt lattice boom cranes. You need the exact reevings, boom angle presets, and load limits that PAT designed. Aftermarket copies skip steps. This one doesn’t.

Warnings: The First Page You Should Read

Page 1 hits you with general information and warnings. PAT doesn’t mess around. The system description starts on page 2, but that warning block is your safety net. I’ve worked with operators who bypass pre-operation inspections. That’s how you snap a cable. This manual includes a full Pre-Operation Inspection checklist on page 22. Use it.

System Description and Operating Console

Chapter 3 lays out the system function, operating console, and control identification. If you don’t know what each button on the EI 65 console does, you’re guessing. Page 4 shows the console layout. Page 5 identifies every control. This is not a generic diagram – it’s specific to the PAT EI 65 for Link-Belt cranes. I’ve calibrated these systems; knowing the control identification saves hours of fumbling.

What Programming Procedures Are Included?

The manual devotes chapter 4 to programming – startup, setting operating conditions, reevings, hoist winch selection, and activating preset limits. Pages 9 through 20 cover this. You need to set boom angle presets (page 15), radius presets (page 17), height presets (page 18), and load limit (page 19). Each has a deactivation procedure on page 20. Miss one step and the system won’t protect you. I’ve seen guys skip the reevings setting and get a false load reading.

14 Pages of Calibration Instructions

Starting on page 26, the calibration section covers warnings, essential information, setup, and the actual calibration steps through page 38. Page 26 is where the serious torque specs and sensor checks live. You need to follow the operational checks on page 38 after calibration. PAT requires you to verify the system after every calibration. I don’t care how many times you’ve done it – check the manual.

Understand the Preset Limits Before Lifting

Preset limits are not optional. Section 4.3 walks you through activating and setting boom angle, radius, height, and load limits. Setting of Load Limit is on page 19. The deactivation and cancellation procedure on page 20 is critical – if you cancel a limit incorrectly, the indicator won’t alarm. The manual warns you: “Deactivation must be confirmed by the operator.” That’s not a suggestion.

See page 26 for the calibration warnings. They’re not the same as page 1. Page 26 gets into specific hazards like electrical shock during sensor connection and crane stability during calibration. I’ve seen guys skip the level-ground requirement. Bad idea.

Service and Maintenance – Page 24

Chapter 7 covers service and maintenance. It’s short, but it tells you what to inspect and how often. Don’t ignore it. The troubleshooting section on page 25 lists fault codes. If you get a code, look it up before power-cycling the system. I’ve cleared codes by following the manual’s procedure instead of guessing.

This manual is not for the guy who wants to wing it. It’s for the operator who wants to go home at night. The PAT EI 65 Operators Manual is the only source for OEM torque specs and calibration sequences. Aftermarket manuals often omit the calibration section entirely – or they jumble the reevings table. Don’t risk your crane or your crew on a copy.

Page 26 is where the calibration section starts. Inside you’ll find essential information and setup for calibration. The manual tells you to have a calibrated protractor, tape measure, and load cell. No shortcuts. If you don’t have the tools, don’t start.

Don’t mistake this for a Manual Transmission publication. This is a PAT factory manual for crane safety systems. Likewise, if you need Manual Transmission specs for a truck crane, that’s a different document. This one only covers the EI 65 load indicator.

What is on page 1 of the manual?

Page 1 contains general information and warnings.

How do I use the calibration section?

The calibration section starts on page 26 and runs for 14 pages through page 38. It includes essential information, setup procedures, and step-by-step calibration steps. Page 31 begins the actual calibration process. You need to follow this exactly – no shortcuts. The manual warns against skipping steps. I’ve calibrated many EI 65 systems and the manual’s procedure is spot-on. Failure to calibrate correctly can cause the load indicator to give false readings. That’s why PAT requires operational checks on page 38 after every calibration. Don’t trust your memory; trust the 1999 manual.
