The Slew Guard Limiter System is intended for use on excavators and cranes in the contstruction and utlity maintenance industries where machines are restricted to working in confined spaces and there is a requirement to limit the slew movement of the machine.
How It Works
The Slew Guard Limiter allows the machine operator to quickly and easily set left and right slew limits from the operator station, and then restricts the machine to working within the permitted slew sector.
As the left or right slew limit is reached a hydraulic solenoid valve is released to cut off the relevent slew hydraulic service, and therefore prevent the machine from entering the exclusion zone. Slew operation in the opposite direction, back into the 'safe' zone, is still permitted.
The system can be installed by any competant engineer, and there is no calibration required.
