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.
