The Edelrid Ohm is an innovative, solution for the problems experienced by climbing partners with a significant difference in weight. That is to say the risk for a heavier lead climber if their partner has difficulty controlling their falls and the risk for a lighter belayer if their partner’s falls pull them off the ground, hurling them against the wall. The OHM is an assisted-braking resistor that you install at the first bolt in the safety chain. In the event of a fall, the OHM increases rope friction so that a lighter belayer can hold a heavier partner without being suddenly pulled off the ground and thrown against the wall. The Ohm still enables smooth paying out and taking in rope when climbing and belaying and has no negative affect on handling. The Ohm was developed for use at both climbing walls and outdoor sport climbing venues.

The development of the Ohm was supported by the Institute of Mechanical Handling and Logistics at the University of Stuttgart. It is an assisted-braking resistor that is attached at the first bolt with a quickdraw and the rope runs through it. In the event of a fall, the rope is pulled into the device’s braking mechanism. This then brakes the fall. The device does not stop the rope abruptly; instead it progressively brakes the speed it runs through, so that the belayer can still dynamically arrest the fall. The Ohm increases the amount of friction in the safety chain, independent of the belay device used. As a result, the belayer needs to apply significantly less hand braking force to the braking rope to arrest the fall and they wont be hurled against the wall in an uncontrolled manner.

The Ohm is designed not to affect rope handling when belaying a lead climber. It neither increases rope drag for the lead climber, nor has a negative affect when paying out rope. The device’s assisted braking mechanism is only activated in the event of a fall.

Including the Ohm into the safety chain increases this factor significantly. With this device, it is now possible for climbers in the lower weight ranges to belay a lead climber, who is up to 100% heavier than the belayer. The Ohm is suitable for ropes with a diameter between 8.6 and 11 mm and is particularly beneficial for belayers with a body weighing upwards of 40 kg.
