A materials handling system (10) comprising a first (60) and second ladder (70) section connectable together to form a longer ladder, a tensioning system (100) attached to each section for tensioning the connected ladder sections, and a trolley (110) arranged to travel along the connected ladder sections, wherein the system includes a cable (158) and pulley for moving the trolley along the connected ladder sections.

A ladder including a first frame, a second frame and a platform assembly. The first frame includes one or more fixed steps. The platform assembly includes a first platform pivotably coupled to the first frame, a second platform pivotably coupled to the first frame, a first linkage coupled between the second frame and one of the first platform and the second platform, and a second linkage coupled to the first platform and the second platform. The ladder is movable between a closed position and an open position.

A ladder is revealed. A sliding rail is formed on a surface of one side of each of two ladder poles of a ladder body. At least one sliding block is mounted and sliding in the sliding rail of the ladder pole. An assembly member is arranged between the sliding blocks of the ladder poles. A ring on user's safety clothing is set on the center of the assembly member and connected to the assembly member during climbing. When the user falls off the ladder accidentally, the sliding blocks connected to the assembly member are also pulled so that the sliding blocks are inclined an angle and the braking end within the sliding rail is against the wall of the sliding rail for braking and slip resistance. Thereby the descending is slowed down and the ladder safety during climbing is improved.

A folding leg for a stepladder is disclosed. The folding leg allows the width of the stepladder base to be narrowed when in the stored orientation and widened while in an in-use orientation.

A semi-cylindrical tubular component with grip component used to carry a ladder distributes the load supported by the user's hand. The ladder carrier device and process increase the contact area of the open longitudinal end or the flat u-channel, of the grip, with the ladder rung or side rails, resulting in a more evenly distributed load. The grip device can be used on both ladder rung and ladder leg supported with tension only, and accommodates hands of a plurality of human operators, and more than one user at a time. Additionally, the ladder may be carried either vertically or horizontally.

A low-profile fly arm step ladder has a pair of first ladder legs with steps and a pair of second ladder legs. Bracket arrangements are mounted to upper ends of the first ladder legs. Each second ladder leg is mounted in a portion of a respective bracket arrangement. A fly arm assembly is provided that has two ends on one side. Each end is mounted with a portion of the bracket arrangement of a respective first ladder leg. The bracket arrangements permit: (i) the second ladder legs to transition from a storage position abutting the first ladder legs to a step ladder position in which the first and second ladder legs contact the floor; and (ii) the fly arm assembly to extend out into a braced single ladder position in which the first ladder legs contact the floor and the fly arm assembly contacts a surface above the floor.

A step ladder includes a first assembly having a first pair of spaced apart rails, a second assembly having at least one rail, and a top cap coupled with the first assembly and the second assembly. At least one of the first and second assemblies may be pivotally coupled with the top cap. The first assembly includes a plurality of rungs coupled with the rails and may exhibit a vertical spacing of a first distance between adjacent rungs, a vertical spacing equal to the first distance between the lowermost rung and a supporting surface (e.g., the ground), and a vertical spacing between the uppermost rung and the top cap that is greater than the first distance. In one particular embodiment, the vertical spacing between the uppermost rung and the top cap is twice the distance of the first distance.
