Weight Compensation in Climbing: Technique, Effect and Practical Use of Brake Assistants

In climbing, the safety of the climber and belayer depends heavily—particularly in the case of a large weight difference—on the control of the brake strand and the pulling force on the belayer during a fall. How brake assistants help to compensate for this difference and improve safety was investigated by DAV Safety Research in collaboration with the Chair of Biomechanics at the University of Bayreuth.
