The OnBelay is an air-over-hydraulic auto belay device that eliminates the need of a belayer when climbing. Utilizing a system used in military aircrafts, The OnBelay automatically retracts the cable rope when the climber ascends, and controls the speed when they descend off the wall. It features a one of a kind system of Self-Adjusting Speed Limiting Valves that descends users safely at a consistent speed of 1m/s, regardless of external factors like temperature or body weight.

  • Reduces the needed staff and operational costs
  • Minimizes the risk of injuries caused by human error
  • Attracts more solo climbers and beginners
  • Increases throughput by reducing time for a climb compared to manual belaying
  • CE certified
  • Low maintenance cost
  • Redundance in the event of:
    • Loss of pressure in the tank – sound and light alarm system option
    • Loss of up to 50% of the hydraulic fluid
    • Malfunction of one of the hydraulic cylinders
  • Minimum downtime – maintenance is done on the spot with no need for shipment of the OnBelay for re-certification
