DS-150 - Load Moment Indicator for Mobile Cranes |
|
.jpg) The DS 150 LMI from PAT America puts a full range of precise information right in the cab. The PAT DS-150 was designed as a more cost effective LMI system for use in small telescopic boom mobile cranes. Tthe DS 150 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 150 offers a full-range of outstanding features, including:
Measures True Load Moment:
By measuring the true load moment the DS 350 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.
Digital LCD Display: Large characters and a super-twisted LCD-backlit for night operation, gives operators a clear and easy view from all angles.
Analog Meter: Along with 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-350 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-150 was initially installed by Grove Worldwide , Shady Grove, Pa the leading U.S. Crane Manufacturer, as standard equipment for the smaller carrydeck cranes beginning in 1991. The system was replaced in 1996 by the DS-160 System from PAT
