OnBelay is air over hydraulic hydro-pneumatic automatic belay device that eliminates the need of a belayer. The device automatically retracts the cable during ascend and controls the speed during descend or in the event of a fall.

The braking system is one of the most dependable ones – the same type of system used to stop military aircrafts as they land on Aircraft carriers worldwide, implemented in their arresting engines.

Add to this our one of a kind Self Adjusting Speed Limiting Valves (SASLV) in our Onbelay will safely and reliably belay you over and over with a consistent descent speed of 1 m/s, regardless of the elements, temperature or your body weight.

  • Cost efficient by reducing the staff needed
  • Minimize injury risks due to human error
  • Attract single and beginner climbers
  • The ONLY European hydraulic autobelay
  • CE certified
  • Fully redundant
  • Fail safe in the event of:
    • Loss of pressure in the tank – sound & light alarm system option
    • Loss of up to 50% of the hydraulic fluid
    • Hose rupture
    • Malfunction of an entire hydraulic cylinder
  • Low maintenance costs – the only consumable that needs replacement is the steel c able
  • Minimum downtime – no annual shipment of the auto belay device for re-certification.
