DS-350GM - Graphic Modular Load Moment Indicator for Mobile Cranes


PAT KruegerThe DS 350 Graphic Modular LMI from PAT America puts a full range of precise information right in the cab. The PAT DS-350GM was designed as a more user friendly LMI system for use in telescopic boom and lattice mobile cranes. The DS-350 Graphic Modular System utilized a graphic display that was suited for the harsh environment associated with construction equipment. This allowed PAT to introduce a graphic user interface to simplify the set-up procedure and eliminate many language issues. The system also introduces a slewing potentiometer to monitor the swing postiion allowing the operator to set up a working area defiinition for unique job-site conditions. The DS 350GM is installed and calibrated to the crane's load chart including specific load and geometric limits or boom length, angle, tip height and operating radius. The systems microprocessor technology allows operators to work with confidence by giving them constant access to the information they need. Having this invaluable data during demanding situations results in more productive lifts.

The DS 350GM offers a full-range of outstanding features, including:

Measures True Load Moment:

By measuring the true load moment the DS 350GM senses boom dynamics, load swingout, wind loading, shock load and the effects of boom deflection. Load moment is measured in lattice boom cranes with a force transducer in the boom pendants, and in telescopic boom cranes with pressure transducers in the lift cylinders.

Graphic LCD Display and a super-twisted LCD-backlit for night operation, gives operators a clear and easy view from all angles.

Analog Indication of relative load moment information, it provides a quick, convenient way for operators to see where they are in the load chart.

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 DS-350GM provides a relay output which can be used to engage an optional lever lockout system to override hoist "up" telescope "out" and boom "down."

Features
  • Displays actual and allowable load, boom length, boom angle, and load radius
  • Alerts the operator in an impending two block condition
  • Quick and easy set-up through the operator’s console
  • User-friendly console
  • Meets SAE and ANSI B-30.5 standards
Self-Diagnostics – Continuously monitors system and sensors. Error codes are displayed to help identify problems and minimize downtime.

The DS-350GM was initially installed by Grove Worldwide , Shady Grove, Pa the leading U.S. Crane Manufacturer, as standard equipment on mobile cranes replacing the DS-350GW in 1996. The system was replaced in 2002 by the i-Flex5 Can-Bus System from PAT
