Hirschmann DS150 2000 Operators Manual – Load Moment Indicator for Hydraulic Boom Cranes

I have seen crane accidents happen because somebody skipped the pre-operational test. That is a fact. If you run a hydraulic boom crane with a Hirschmann DS150 Load Moment Indicator, this Hirschmann DS150 2000 Operators Manual (43 pages) is the factory document that tells you what each button does and what to check every single day before you lift a load. PAT designed the system. They wrote the book. Aftermarket copies? I trust them about as far as I can throw a boom section.

Run the Pre-Operational Test Daily

Page 1 of this manual has a warning that says ALWAYS PERFORM PRE-OPERATIONAL TESTS. That is not a suggestion — it is a requirement. The DS150 system relies on inputs from boom angle, length, and pressure sensors. If one of those is off by half a degree or a few PSI, the load readings shift. You will not know until you go through the test sequence described in this manual. The procedure is laid out step by step, with specific button presses on the DS150 control panel. Follow it exactly.

Know Your Boom Angle and Radius Readings

The system continuously calculates tip height, working radius, and rated load of your crane. This manual explains how the DS150 uses sensor data to give you those numbers. If you see a reading that seems wrong, the troubleshooting section (based on the factory logic) tells you what to check — usually a sensor connection or a calibration issue. Ignoring a suspicious number leads to an overload condition that the alarm might catch, but why risk it?

Understand the Warning and Cut-Off System

Two-stage warning: first an audible alarm and a warning light, then if you keep pushing, the DS150 cuts off unwanted crane movements. The manual documents which movements get cut off and under what conditions. This is not a guess. Page 4 states the system “will warn the operator by sounding an audible alarm, lighting a warning light and cutting-off unwanted crane movements.” Know which movements are cut so you do not get caught in a half-raised load.

Read the Warnings Section First

Section 2 of this manual, starting on page 5, is blunt. It says the LMI is not a substitute for good operator judgment. That is the kind of statement you do not see in aftermarket PDFs. The original PAT document includes legal disclaimers and operational responsibilities. If you are training new operators, make them read these two pages out loud. It covers daily inspection requirements and the limitations of the system. Manual Transmission comparison? Not applicable here, but the point is that you need a reliable source of truth.

7 Systems Covered – From Boom Length to Overhoist Alarms

Although the manual is only 43 pages, it covers the entire DS150 system: boom length sensor, angle sensor, pressure transducer, control panel functions, alarm module, cut-off relays, and the wiring harness connections. Each component has a functional description in the General Information section. If you need to understand how the angle sensor feeds data to the processor, it is on page 4. If you need charge pressure? Page 73 is not in this book — it is an operator’s manual, not a service manual. But for daily operation and pre-shift checks, this is the document.

That is the difference between factory OEM and a reprint. The PAT copyright page (page 2) says “No part of this document may be photocopied, reproduced, or translated to another language without prior written consent.” AutoRepairManuals sells the original scanned file — not a third-party rewrite. You get the exact same text, diagrams, and warnings that came with the DS150 when it left the factory in 2000. Hirschmann PRS 40 EZ 2010 Operators Manual – Factory Specs covers a different indicator system, but if you run multiple cranes, you want the same OEM quality for each.

For crane owners who also handle smaller equipment, Hirschmann iSCOUT expert compact 2007 Operators Manual – Factory Crane Specs and Hirschmann PAT PRS 80 2005 Operators Manual – Factory Specs for Crane Load Indic are available for their respective systems. Each one is a direct scan of the factory booklet, with no missing pages and no re-labeled diagrams.

FAQ – Hirschmann DS150 2000 Operators Manual

Does this manual cover the DS150 for all crane models?

The manual covers the generic DS150 system. Specific crane configurations may require additional setup parameters. Check page 1 for application notes.

Is this a reprint or an original OEM document?

This is a direct scan of the factory PAT Operators Manual dated October 20, 2000 (P/N 031-300-101-042 Rev A). It is not a reprint nor a third-party rewrite. The original copyright and trademark notices are intact. You get the same content as the paper manual that shipped with the DS150.

What are the torque specs for mounting the LMI sensors?

Torque values are not in this operator’s manual. Those specs belong in the installation manual. This manual focuses on operation and pre-shift checks.

How often should I perform pre-operational tests?

Daily, before each lift cycle. No exceptions.
