A side rail assembly useful for securing a deck of a scaffold comprises a side rail configured to be supported between two ladder frames in first and second orientations. The side rail includes first and second support surfaces for supporting the deck in the first and second orientations, respectively. First and second vertically aligned and closed slots are formed in respective opposing surfaces of the side rail. The side rail assembly further comprises a locking pin assembly to secure the deck against one of the support surfaces of the side rail depending on the orientation. The locking pin assembly is configured to be removably engaged with the first and second slots of the side rail in both the first and second orientations.

A collapsible work platform includes toprails engaging fixedly to a platform, backrails engaging the toprails pivotally through a hinge at an end portion of the pair of toprails, frontrails engaging the toprails pivotally through a hinge at the other portion of the toprails, link bars engaging the toprails pivotally, a footstep engaging the link bars and the frontrails pivotally, and braces engaging the backrails and the frontrails, and the toprails pivotally through hinges. Each of latching plates having a latching portion engages fixedly the end portions of the backrails and the frontrails maintaining the deployed state by the braces. Each of stopper blocks engage protrudingly an inner side and an outer side of one end and the other end of the toprails, so that the latching portion of the latching plate contacts and engages fixedly and the backrails and the frontrails are not deployed further beyond a certain point.

A scaffold includes a first end frame assembly. The scaffold includes a second end frame assembly. The scaffold includes a first side brace assembly supported by the first end frame assembly and the second end frame assembly. The scaffold includes a second side brace assembly supported by the first end frame assembly and the second end frame assembly. Each end frame assembly has a first rail with holes and a caster assembly and a second rail with holes and a caster assembly and a horizontal that is attached to each rail. Each side brace assembly has a locking pin in proximity to each end which engages with a hole in a respective rail, and an associated guard disposed about each pin. Each locking pin has a handle which has a length that extends below the associated guard on an interior side of the guard. A method for a scaffold.

A guard rail system for a scaffold can be configured in multiple configurations. In one configuration, two gates are pivotally mounted to opposing ends of a first side rail assembly, and are latched to a second side rail assembly. In another configuration, the gates are also pivotally mounted to opposing ends of a first side rail assembly, but the second side rail assembly is removed, and the gates are latched to support posts that replace the second side rail assembly. Removal of the second side rail assembly allows better access to a nearby worksite. Related methods are also disclosed.

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.

A scaffold includes a first end frame assembly. The scaffold includes a second end frame assembly. The scaffold includes a first side brace assembly supported by the first end frame assembly and the second end frame assembly. The scaffold includes a second side brace assembly supported by the first end frame assembly and the second end frame assembly. Each end frame assembly has a first rail with holes and a caster assembly and a second rail with holes and a caster assembly, and a horizontal that is attached to each rail. Each side brace assembly has a locking pin in proximity to each end which engages with a hole in a respective rail, and an associated guard disposed about each pin. Each locking pin has a handle which has a length that extends below the associated guard on an interior side of the guard. A method for a scaffold.

This invention relates to a formwork support member, and a scaffold structure formed from at least a pair of adjacent formwork support members. The formwork support member comprises at least two spaced vertical members, at least one connecting member bridging said vertical members to form thereby a rigid formwork support member, each vertical member including a plurality of attachment means at spaced intervals there-along for releasable attachment thereto of at least one brace member extending between adjacent formwork support members to form the scaffold structure.

A work platform system having a first work platform. The first work platform having a first hook assembly and a first latch assembly. The system having a second work platform. The second work platform having a second hook assembly and a second latch assembly. The first work platform locked to the second work platform through the first hook assembly engaging with the second latch assembly and the first hook assembly in the use position. A method for using a work platform system. A method for producing a work platform.

A scaffold includes first and second ladder frames. Each ladder frame includes first and second vertical supports, and first and second horizontal supports mounted to the vertical supports. The first horizontal support is formed of tubular material, and has a base or central section and an asymmetric flattened end section. The end section is mounted to the first vertical support. The central section has a top centerline and a bottom centerline. The end section has a vertically elongated cross section compared to the central section. A top of the end section aligns with the top centerline of the central section; and a bottom of the end section is disposed below the bottom centerline of the central section. Related methods and tools are also disclosed.

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.
