The claimed invention relates to a folding utility scaffold that greatly reduces the space requirement for shipment when the utility scaffold is in the folded configuration while maintaining or increasing stability. The scaffold includes first and second ladder frames and a hinge assembly interconnecting the ladder frames. The scaffold comprises first and second ladder frames and a hinge assembly interconnecting the ladder frames. The hinge assembly enables movement of the scaffold between an unfolded configuration in which the ladder frames are spaced apart and a folded configuration in which the ladder frames are disposed side by side, i.e., with the ladder frames touching. The ladder frame and hinge assembly are designed to avoid interference between components of the hinge assembly and components of the ladder frame in the folded configuration so that the ladder frames can be disposed in side-by-side relation in the folded configuration.

A railing assembly includes at least one ratcheting post and at least one connection post. The at least one ratcheting post includes at least one ratcheting assembly attached to the at least one ratcheting post for selectively engaging a strap and the at least one connecting post including at least one attachment point for engaging an attachment member on the strap.

Preceding guardrail for a scaffolding system for buildup of a scaffold bay. The guardrail assembly comprises a guardrail, a base part, a mounting system for mounting of the base part to a part of the scaffold bay, at least a first post and a second post, and a lifting arm. The guardrail extends along a longitudinal axis. The base part extends substantially parallel to the longitudinal axis of the guardrail. The first and second post are each pivotably connected to the guardrail by a first pivoting point and pivotably connected to the base part by a second pivoting point, whereby the guardrail, the base part, the first, and the second post together form a parallelogram link system. The lifting arm is fixedly connected with the first post and extends in line with the first post from the second pivoting point away from the first pivoting point.

A support apparatus 1 for supporting a user in an elevated working position above a ground surface G comprises a frame 60 for supporting a floor portion 20 of the support apparatus and a plurality of leg members 40a, 40b mounted to the frame 60 for supporting the frame above the ground surface G. Each leg member has a foot portion 42 for engaging the ground surface G. Each leg member is rotatably mounted to the frame for rotation about a rotational axis which is substantially perpendicular to the width and the length of the frame and each leg member extends from the frame in a radial direction of the rotational axis, whereby the foot portion is offset from the rotational axis.

A configurable scaffolding system is configured to facilitate simplified, reconfigurable access to a plurality of horticulture racks. With use of the configurable scaffolding system, operator convenience and safety are improved, and increased plant density in horticultural applications can be achieved.

A railing assembly includes at least one ratcheting post and at least one connection post. The at least one ratcheting post includes at least one ratcheting assembly attached to the at least one ratcheting post for selectively engaging a strap and the at least one connecting post including at least one attachment point for engaging an attachment member on the strap.

A vertical raising safety rail. The safety rail includes lower linkage arm assemblies that are connected to a base and to a center rail assembly and configured to raise or lower the center rail assembly relative to the base when a rotational force is applied to the drive shaft. The safety rail also includes upper linkage arm assemblies that are connected to the center rail assembly and to a top rail. The upper linkage arm assemblies are connected to corresponding lower linkage assemblies and are configured to move the top rail relative to the center rail assembly. When the top rail is raised, one or more safety curtains are unfurled from a take-up roller inside the top rail to provide a safety curtain in the vertical plane of the safety rail.

A vertical raising safety rail having a moveable top rail, a base, a movable center rail assembly positioned above the base and below the top rail, a drive shaft, and a motor that provides rotational power to the drive shaft. The safety rail further includes a pair of spaced apart lower linkage arm assemblies that is operatively connected to the base and to the center rail assembly and configured to raise or lower the center rail assembly relative to the base when a rotational force is applied to the drive shaft. The safety rail also includes a pair of spaced apart upper linkage arm assemblies that is operably connected to the center rail assembly and to the top rail. The upper linkage arm assemblies are operably connected to corresponding lower linkage assemblies and are configured to move the upper rail relative to the center rail assembly. When the rotational force is reversed, the safety rail collapses into a compact footprint.

The present disclosure relates to systems and methods involving collapsible guardrails. An example system includes a top rail, a mid rail, an enclosure, and at least two posts. Each post includes an upper primary member, a lower primary member, an upper secondary member, and a lower secondary member. The upper primary member and the lower primary member are slidably coupled to at least one slot in the mid rail. The upper secondary member is rotatably coupled to the upper primary member and the lower secondary member is rotatably coupled to the lower primary member. The upper primary member is further coupled to the top rail and the lower primary member is coupled to the enclosure.

An integrated hand rail structure which is foldable from a user engagement upright position into a flat transport position on mobile industrial equipment. The hand rail is supported on a walkway structure, including an extensible section having rail and post which are pivotally attached thereto. Selective release and locking pin assemblies provide for hand rail locking in upright user position and releasable for a folding flat transport position.
