4.13 Ascent of the Rescuer on the Rope
Always taut rope on safety line.
A pulley can be constructed using the hand rope clamp and rope grab for climbing onto the cabin roof. When doing so,
the hand rope clamp must be fastened on the taut part of the hold rope. The loose end of the hold rope is then inserted
through the spring hook of the hand rope clamp to complete the pulley.
