X Watch XW5 – RCI, Height & Slew Limitation

Make: X Watch
Model: XW5
Restriction: RCI, Height & Slew Limitation

The XW5 Excavator Safety System can be configured to work on any type of hydraulic excavator. Overload, height, and slew limitation are controlled using proportional soft-stop hydraulic valves providing accurate and repeatable performance without detriment to the machine. A basic dig depth monitor is available when th RCI is not required. If hazards arise, XW5 will automatically flip to the relevant display page. Tracked machines have automatic sectored lifting duties for over the front/rear operation and over the side. Load charts are ISO10567.

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.


Options Include:

  • Access Key Switch (Prevents / allows setting changes)
  • Track Lock (Inhibits travel when a height limitation is active)
  • Beacon (Height limit active indication)
  • Offset Boom Sensor (Monitors offset boom angle – single proximity switch detection also available)
  • Reeling Drum (Monitors telescopic arm extension, single proximity switch detection also available)
  • Platform Sensor (Monitors chassis pitch and roll angles)
  • Auto Duty Switching (Proximity switch detection for up to four lifting duties)
  • Data Logger (CAN bus mounted event recorder with SD card)
