Abstract:
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.
Abstract:
A ladder is provided comprising a first pair of spaced apart rails and a plurality of rungs extending between and coupled to the first pair of spaced apart rails. A pair of hooks are located such that each hook is positioned adjacent and upper end of an associated rail. A securing apparatus is coupled adjacent the upper end of the first pair of spaced apart rails. The securing apparatus includes a pair of spaced apart engaging members and may include a cross-member coupled therebetween. Each of the engagement members is pivotal with respect to an associated rail of the first pair of spaced apart rails. In one embodiment, the securing apparatus lacks any biasing members (e.g., springs or actuators) or locking members. The engagement members and hooks cooperatively encircle and overhead, generally horizontal support member to support and secure the ladder in a desired position.
