Abstract
A fall arrester for a climbing protection system to prevent a person from falling from a ladder, platform, or similar structure. The fall arrester can be guided in a guide rail and has a housing and a pawl with an attachment point where the person to be secured is attached. The pawl is swivellable between an unlocked and a locked position of the fall arrester so that in the unlocked position, the connection line between the rotational axis and the attachment point form an acute angle to the horizontal, and the torque exerted by the spring on the pawl is less than the torque produced by the weight force of the fall arrester when the fall arrester is held at the attachment point.
