An apparatus comprising a base, a first orthogonal portion and a second orthogonal portion. The first orthogonal portion may (i) be connected to a first side of the base near a first edge of the base and (ii) have a rectangular shape. The second orthogonal portion may (i) be connected to an interior of the base and (ii) have a rectangular shape. The first orthogonal portion and the second orthogonal portion may be positioned to secure a plurality of braces. The second orthogonal portion is positioned to secure a plurality of scaffolds.

A stabilization and anti-rotation system provides for secure interconnection between a scaffolding work platform and two primary platforms, each of which is attached to a ladder, and prevents relative movement between the primary platforms and the scaffolding platform. A locating block is attached to a plate of each primary platform 402. A pair of spaced apart and vertically oriented guide blocks are attached to a facing plate on each end of the work platform and positioned so that a guide slot is defined between the blocks. When assembled, the locating block is closely captured between the guide blocks and the structure provides stability and prevents rotation of the work platform relative to the primary platforms.

Platform systems can support a user at an elevated position while being drivable or mobile via wheels and a drive system. Rail assemblies can be folded or collapsed so that the platform system can be carried by a user from one location to another. Hand controls are operable by the user from the elevated position to move the platform systems across a ground surface and can have automatic braking capability. Each side of the platform system can be independently driven, thereby allowing zero point turning and other fine control maneuvers. Structures at the base of the platform system can limit or prevent tipping or tilting. A cage system can help keep a user on the platform(s). Platforms can be collapsed or stowed with the rest of the platform system.

The racking system comprises at least one rack and a mobile scaffold, the scaffold comprising a frame defining opposite first and second sides, a platform carried by the frame, for supporting a person above ground, a scaffold guide member carried by the frame on the first side, a rack guide member carried by the rack which is complementary to the scaffold guide member, with the scaffold guide member releasably engaging the rack guide member such that the scaffold is retained against the rack and is guided along the rack while allowing the scaffold to be movable along the rack, and a support member carried by the frame for allowing releasable support of the frame by either one of the rack and the ground. The frame is linked to a single rack of the racking system.

A mobile assembly support unit that includes an assembly line sync mechanism having a line engagement unit coupled to a rotatable sync arm, a propulsion unit having a propulsion wheel and a propulsion motor, a translation arm coupled to the propulsion unit and engageable with the rotatable sync arm, and an air cylinder coupled to the propulsion unit. The air cylinder is actuatable between a retracted position and an extended position such that when the air cylinder is in the retracted position, the translation arm is engaged with the rotatable sync arm and the propulsion unit is in a lifted position and when the air cylinder is in the extended position, the translation arm is disengaged with the rotatable sync arm and the propulsion unit is in a descended position.

A lightweight, multi-function scaffold includes an adjustable height platform that slidably mounts between two ladder frames and a plurality of outriggers to increase stability. The outriggers attach to the ladder frames of the scaffold and extend beyond an end of the scaffold in the longitudinal direction to increase the maximum base width. Increasing the maximum base width increases stability in the longitudinal dimension and reduces the risk of tipping the scaffold end over end when a user climbs the ladder frame to access the platform.
