A modular crossover system includes one or more platforms, one or more platform guardrails attached to the platform, a plurality of towers supporting the one or more platforms, a plurality of stile assemblies attached to the platforms, or a combination of towers and stile assemblies. An optional fixed ladder may be attached to one of the platforms.
A rolling ladder includes opposing side members between which a plurality of treads are disposed at predetermined locations to define a ladder. The ladder further includes a support structure coupled to the ladder and including a front wheel support coupled to a plurality of rolling devices. A leg assembly has a user-adjustable length leg, allowing the user to extend or retract either leg to accommodate uneven or irregular floor surfaces. The leg length may also be adjusted to allow for wear in the material of the leg. A lock mechanism is responsive to user actuation and is configured to move the rolling devices from a rolling position to a retracted position, wherein the leg of the leg assembly contacts the floor to thereby inhibit movement of the ladder.

Dual track ladder with brake mechanism that is automatically applied to the upper tracks to hold the ladder in place during use
A ladder system includes an overhead track system, a ladder, a latch and a carriage. The overhead track system includes a first guide track and a second guide track. The carriage is operatively configured to move longitudinally along the first and second guide tracks and to move laterally between the first and second guide tracks. The ladder is pivotally mounted to the overhead track system. A lateral carriage brake is provided which prevents lateral movement of the ladder, and a longitudinal carriage brake is provided to prevent longitudinal movement of the ladder. The latch is operatively configured to affix the ladder to the carriage.

A ladder assembly for use with movable shelving is disclosed. The ladder assembly may comprise an overhead track assembly, a carriage, and a ladder. The overhead track assembly includes a first guide track and a second guide track. The carriage is operatively configured to move longitudinally along the first and second guide tracks. The ladder is pivotally and slidably mounted to the carriage. The ladder has an operating position and a stored position. The operating position is located in an open available aisle of the movable shelving. The stored position may be located substantially vertical and outside of the aisle of the movable shelving allowing the movable shelving to close the aisle without interference from the ladder.

The disclosed ladder system may be disposed in a store, warehouse, library, or similar facility where two storage shelves form an aisle. The ladder can be pivotally attached to a roller structure that moves along a length of the aisle on a guide track. The guide track may be disposed along sides of the storage shelves. The roller structure may be formed by a lateral rod extending between and coupled to two roller carriages. Further, because the ladder is pivotally attached to the roller structure, the ladder may fold substantially out of the aisle when the ladder is not in use.
A guide track system and a bracket assembly thereof for supporting guide tracks thereof are provided. The guide track system comprises a first guide track piece, a second guide track piece, and a bracket assembly configured to support the first and second guide track pieces. The bracket assembly comprises a mounting feature configured to be mounted to a support structure, and a guide track supporting feature connected to the mounting feature and configured to support a portion of the guide track mounted thereon. The guide track supporting feature, in turn, comprises a body having a first end, a second end, and a longitudinal axis extending through the first and second ends, wherein the first end is configured to be coupled with an end of the first guide track piece, and the second end is configured to be coupled with an end of the second guide track piece.

Dual track ladder with brake mechanism that is automatically applied to the upper tracks to hold the ladder in place during use
The ladder system is disposed between two spaced storage shelves of the types found in crowded warehouses. The ladder is mounted on overhead guide tracks and may be moved longitudinally along the shelves and laterally between the shelves. Locating means are provided for immobilizing the ladder against movement laterally and longitudinally. The locating means includes a pair of spring-loaded casters and rubber pads at the lower end of the ladder and a pair of braking mechanisms overlying and engageable with the guide tracks when subjected to the weight of the user to prevent movement of the ladder at the top thereof either intentionally or unintentionally. Finally, a lateral brake is carried by the ladder which prevents the roller carriage from moving laterally. The brake is applied when the ladder is in use.
