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. A fall arrest mechanism, or an ascender device, may be coupled with the section of rope extending up the ladder between the rails and in front of the rungs.

摘要： 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.
摘要翻译：提供了梯子，其包括第一对间隔开的轨道和在第一对间隔开的轨道之间延伸并耦合到第一对间隔开的轨道的多个梯级。一对钩被定位成使得每个钩定位在相关轨道的相邻和上端。紧固装置邻近第一对间隔开的导轨的上端连接。固定装置包括一对间隔开的接合构件，并且可以包括在其间连接的横向构件。每个接合构件相对于第一对间隔开的轨道的相关导轨枢转。在一个实施例中，固定装置缺少任何偏压构件（例如，弹簧或致动器）或锁定构件。接合构件和钩协调地环绕和顶部，大致水平的支撑构件以将梯子支撑并固定在期望的位置。
