摘要： A ladder is provided which may include a positioning system, a fall arrest system, or both. In one embodiment, a rope and pulley system is provided wherein a first end of the rope is coupled to a base section of the ladder, a second end of the rope is coupled with a fly section of the ladder, and the rope extends between a plurality of pulleys. In one particular embodiment, the rope extends between five different pulleys, two being coupled with the fly section and three being coupled with the base section. At least one portion of the rope may extend along the side of the ladder (e.g., along the side of a rail of the fly section) while another section may extend up the front of the ladder between the rails and in front of the rungs.

In one embodiment, a ladder includes a first assembly having rails and rungs, a second assembly having rails and rungs, and one or more hinges coupling the first and second assemblies together such that the first and second assembly may be positioned relative to one another in at least a position or state and at least a second position or state. A top cap is coupled to the rails of the first assembly, such that when the first and second assemblies are in the first position, the rails of the second assembly do not contact the top cap. When the first and second assemblies are in the second position, each rail of the second assembly is at least partially nested in one of a pair of channels formed in the top cap.
