The PAT Hirschmann PRS 145 LMI displays a full range of precise information in the operator’s cab. Designed for use on mobile cranes, the PRS 145 is installed and calibrated to the load chart of each crane – including specific load and geometric limits on boom length, angle, and operating radius. The PRS 145 load moment indicator gives the operator the information necessary to fully utilize the cranes capacity while keeping within the working limits of the crane.
The PRS 145 is designed to be set up quickly and easily in the field. This is done through the user-friendly, self-guided, interactive setup procedure, which is performed entirely through the operator console.
Like all PAT Hirschmann products, the PRS 145 is designed and built to operate under the most rugged conditions. Parts are standard, modular and interchangeable— and they’re readily available.
PAT Hirschmann PRS 145 LMI Features
- Quick, Easy Calibration – Exclusive AccuCalTM calibration software allows calibration through the operator’s console by your local dealer. No additional device or personnel is needed. The program utilizes a pass code that prohibits access to unauthorized personnel.
- Measures True Load Moment – By measuring the true load moment, the PRS 145 senses boom dynamics, load swingout, wind loading, shock load and the effects of boom deflection. Pressure transducers in the lift cylinders of telescopic boom cranes are used to measure load moment.
- Digital LCD Display – Large characters and a super-twisted LCD—backlit for night operation—gives operators a clear and easy view from all angles. Integrated Light bar The integration lightbar provides a quick reference of crane utilization
- Anti-Two-Block – A special hoist limit switch sounds an alarm and flashes a visual warning of an impending two-block condition.
- Function Control Lever Lockout – When the LMI System senses an overload or an impending two-block condition, the PRS 145 provides a relay output which can be used to engage an optional lever lockout system to override hoist “up” telescope and “out” and boom “down” functions.
- Self-Diagnostics – Continuously monitors system and sensors. Error codes are displayed to help identify problems and minimize downtime.
