X Watch XW3 – Angle & Lateral Slew Limits

Make: X Watch
Model: XW3
Restriction: Angle & Lateral Slew Limits

The X Watch XW3 Excavator safety system can be configure to work on a variety of articulated hydraulic plant. Slew limitation is controlled using proportional soft-stop hydraulic valves providing accurate and repeatable performance without detriment to the machine.

  • Operation is fail safe and fully automatic with function selection never more than two key presses away.
  • Dependant on installed options, XW3 can support both single/dual parallel ‘wall’ limits and angular limits.
  • Slew speed will ramp down on approach to a limit, and soft-stop at the limit. Full power is always available if moving away for a slew limit.
  • A slew limit can be either manually keyed in or set automatically by positioning the machine equipment and pressing HERE.
  • 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.
  • XW3 measures to the front and equipment centre line. Tool width must be taken into consideration when manually setting limits.


Options Include:

  • Access Key Switch (Prevents / allows setting changes)
  • Beacon (Height limit active indication)
  • Reeling Drum (Monitors telescopic arm extension, single proximity switch detection also available)
  • Platform Sensor (Monitors chassis pitch and roll angles)
  • Data Logger (CAN bus mounted event recorder with SD card)
  • 12VDC Valve Coils (No cost option for smaller machines)
  • Angle Sensors (If not specified, only angular slew limitation will be available)
