X Watch XW4 – Height & Slew Monitoring

The XWatch XW4 Excavator safety system can be configured to work on a variety of articulated hydraulic plant. Height and slew limitation is controlled using proportional soft-stop hydraulic valves providing accurate and repeatable performance without detriment to the machine.

Height Limitation

• Operation is fail safe and fully automatic with function selection never more than two 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 Limitation

• 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.

MAJOR COMPONENTS CARRY A FIVE YEAR GUARANTEE EXCLUDING MIS-USE AND PHYSICAL DAMAGE.
