XW4 Series Height & Slew Limitation Excavators & Backhoe loaders

Height Control

Operation is fail safe and fully automatic with function selection never more that two key presses away.

All potential machine high points are monitored and appropriate motions controlled. Full power is always available to move away from a limit.

Motions are controlled with ramped slow down
on approach and soft-stop. There is no machine ‘bounce’, overshoot, or undershoot. An optional chassis sensor can be installed to correct for terrain slope.

Slew Control

Single/dual parallel wall or angular limitation are available. When walls are in use, the front end equipment is also monitored and controlled for limit breach.

Limits can be either manually keyed in or set by positioning the machine. If both limits are active, the system will automatically flip to the appropriate display should a hazard approach occur. Set up is simple, quick, and can be protected with an optional access key switch. All settings are retained and will be active on start-up.

Options
