A ladder supporting device for supporting a ladder in upright orientation at an upright surface comprises a channel extending longitudinally from a first end to a second end arranged horizontally spaced across the upright surface with a backside facing the upright surface, a holding device located outside the channel distal to the upright surface, and at least one wheel rotatably supported on an axle connected to the holding device and passing into the channel which receives the at least one wheel such that the holding device is positionable longitudinally of the channel by rolling movement of the at least one wheel along the channel.

A platform ladder apparatus (2) has a transport position and a use position in which the apparatus is arranged to lean against a wall (W) for performing work at an elevated level. The apparatus (2) has a ladder (4) and a working platform (20). A proximal side of the platform is pivotally connected at an upper end of the ladder such that it may be pivoted towards the ladder (4) to a stowed position essentially parallel to the ladder (4). The apparatus further comprises a pair of wall support arms (80) for stabilizing the apparatus in the use position in relation to the wall. The wall support arms (80) are connected to the platform (20) for movement between a stowed arm position in which the arms (80) project out from a distal side (24) of the platform (20) thereby preventing use of the apparatus, and a stabilizing arm position in which the arms (80) project sideways from the platform (20) in opposite lateral directions, respectively, for stabilizing the apparatus (2) in relation to the wall (W).

Walk-through safety devices for ladders meeting ANSI and OSHA standards are positioned at the top end of the ladder and are comprised of two, juxtapose-position, mirror image members. One each is mounted on a respective ladder side rail, Each member includes a sleeve (or rectangular tube) which slides down over a respective ladder side rail, a pressure bar which is tightened against the side rail with a knob operated screw, a pivoting engaging lock plate, and a lock plate tab cover plate. A horizontal hand grip framework is held outboard of the ladder side rails vertically upward, being at an angle of about 14.5 degrees upward from the longitudinal axis of the sleeve and side rail when resting against a structure. The framework is held in that position by a flared tube which is bent in two directions.

A ladder having a first rail. The ladder having a second rail. The ladder having a plastic top directly attached to the first rail and second rail with fasteners. The top having a first side and a second side. The first side having a gap with a surface with a first rectangular slot and a second rectangular slot extending from the first rectangular slot so an external corner can fit into the first rectangular slot when the top leans against the corner. The surface of the first side having a first notch in the gap so a first rectangular plank can fit into the first notch when the top leans against the plank. The first notch having a width slightly larger than a width of the first plank. A ladder top. A method for using a ladder.

A strand grab for a ladder having a hook assembly, a gate assembly engaged with the hook assembly and a biasing spring. The biasing spring produces a return biasing force which is less than a weight force of the ladder when the hook assembly rests on the strand allowing the gate assembly to close with the hook assembly and squeeze the strand between the gate assembly and the hook assembly in a closed position and hold the ladder in place with the strand. A ladder for use with a strand having a first rail and a second rail. The first rail has a first strand grab directly attached to the first rail and the second rail has a second stand grab directly attached to the second rail. A method for using a ladder. A method for making a ladder.
