A foldable scaffold platform has a first scaffold platform body and a second scaffold platform body which are interconnected by an articulation, where the scaffold platform can be folded up for the assembly, disassembly, and transportation thereof, where the width of the scaffold platform is reduced, preferably halved, in the folded state. Each scaffold platform body at the end sides when viewed in the longitudinal direction of the scaffold platform has in each case connection means, in the form of hooks, for connecting the scaffold platform to cross bars of a scaffold. Furthermore, the scaffold platform at the end sides thereof when viewed in the longitudinal direction has in each case an anti-lift protection. The anti-lift protections are disposed so as to be mutually diagonal such that in the folded state of the scaffold platform only a first anti-lift protection locks the scaffold platform to a first cross bar.

A load-adjustable vertically moving scaffold comprises a base unit, a work support provided on an upper part of the base unit and a lift supporting unit supporting the work support to vertically move with respect to the base unit, and the lift supporting unit comprises fixed guide members extended upward from both sides of the base unit, slope guide members installed at front sides of the fixed guide members and configured to be tilted with respect to the fixed guide members, a lift supporting shaft configured to vertically move along the slope guide members, and an elastic member having one end fixed to one side of the work support adjacent to the fixed guide members and other end connected with the lift supporting shaft to apply an elastic bias to the lift supporting shaft toward the fixed guide members.

A device for moving equipment operative for applying an outer coating on structures by a construction worker has a first part moveable by a construction worker for holding and moving at least one vertical bar for supporting a platform for the standing of the construction worker and provided with wheels, and a second part also moveable by a construction worker, formed for holding and moving the platform for standing of a construction worker, and removably receivable in the first part, so that when the second part is removed from the first part, the first part can move the at least one vertical bar for supporting the platform, but when the second part is received in the first part, the first part and the second part can move the platform, and a third part securely supports the first part, and the second part, when assembled, securely supports the first part with a vertical bar during their movement.

An adjustable coupling system is provided for efficiently and removably coupling objects such as platforms together in a linear or diagonal orientation. The adjustable coupling system generally includes a second receiver on a first platform and a first connector on a second platform. The first connector is adapted to be removably inserted within the second receiver such that the first connector is prevented from vertical movement with respect to the first platform. A first locking member is positioned near the first receiver on the second platform. The first locking member is adapted to selectively engage with the second connector when the second connector is positioned within the first receiver to pivotally connect the first platform and the second platform. A work platform or catwalk can be formed with linear sections, diagonal sections, and/or a mix thereof for a wide range of uses.

A set of parts for providing a hoist (1, 101, 102) for a scaffold, the set of parts comprising a platform (2) adapted for carrying at least one object and comprising at least two gear elements (63, 64), the at least two gear elements being arranged at each of two opposing sides (25, 26) of the platform, two frames (31, 32) adapted for being arranged at each of the two opposing sides of the platform, the two frames each comprising one rack element (310, 320) arranged extending in a longitudinal direction (L) of the frame, and one motor (4) for moving the platform along a longitudinal direction of the two frames and for controlling the movement of the platform synchronously with respect to each of the two frames.

A scaffold has latch assemblies that are configured to hold a deck of the scaffold against a side rail of the scaffold. The latch assemblies include a shaft that is configured to extend through slots in the side rail. A locking tab at the end of the shaft presses against the deck due to action of a spring that urges the shaft downward relative to the side rail. The deck advantageously has an edge recess that receives the locking tab. The edge recess may be sized so that lock tab is flush with or below the top surface of the deck. A collar is slidably disposed on the shaft and is interposed between the bias element and the locking tab and is configured to help prevent the bias element from becoming entangled in the slot. The disclosure also relates to related latch assemblies, side rail assemblies, and methods.
