Abstract: It is an object of one or more embodiments of the present disclosure to provide a retractable mezzanine walkway, which when used in conjunction with high-density mobile shelving systems, expands and rolls out, creating an aisle for which employees can walk down. The retractable mezzanine walkway includes pairs of mobile shelving units configured to sit on top of parallel tracks. The retractable mezzanine walkway is configured to roll out between a pair of mobile shelving units when the pair of mobile shelving units is moved apart, such that an aisle is created, and configured to store inside the pair of mobile shelving units when the pair of mobile shelving units are moved together.

Abstract: A brake for retaining a mobile carriage on which apparatus such as storage facilities are located. The brake includes a pivot member with a release end and a locking end and with a claw at the locking end. The claw engages a slotted member when the locking end is depressed. The opposite end of the pivot member from the locking end is the release end. Adjacent the release end is a slot which rides on a stoop pin to prevent the release end from being depressed below the horizontal.

Abstract: A brake for retaining a mobile carriage on which storage facilities are constructed and having a slidable actuating assembly with a claw which engages a slotted member when the actuating assembly is depressed. The mobile carriage is mounted on a platform with a track in which the mobile carriage rolls and with a channel in which the slotted member is secured. A back plate is used to mount the brake on the mobile carriage. A cover is mounted on the back plate and an actuating assembly extends through and is slidably mounted in the pair of openings in the cover so that the actuating assembly may move to and from the platform.
