An assembly for installation, repair, or maintenance of balcony-mounted displays. The assembly may include a straddling component or frame, an anchoring assembly for selectively fixing one end of the straddling component in a desired location along the balcony, and a person-holding structure suspended from the balcony by another end of the straddling component. The straddling component may include forward vertical supports extending from the person-holding structure, horizontal supports attached to the forward vertical supports, and aftward vertical supports attached to the horizontal supports. Transport wheels may be rotatably attached to the aftward vertical supports, for rollable relocation of the platform relative to the balcony. The anchoring assembly may include both forward and aftward extension pieces attached to the aftward vertical supports and selectively adjusted to cooperatively fix the aftward vertical supports between a balcony wall and a heel-kick surface below the balcony seating.

A personnel platform facilitates maintenance on a loop sorter of a material handling system in a distribution center. The personnel platform includes wheeled axle assemblies, having left and right wheel hub assemblies connected by a lateral support structure, engaged for longitudinal travel to opposing wheel channels of a section bed of the loop sorter that guide a train of material handling carriages. The personnel platform also includes a carrier platform comprising multiple sub-platforms, such that each sub-platform is pivotally attached to an adjacent sub-platform. Further, the personnel platform includes a rail assembly having upright structures and side rail assemblies attached between an adjacent pair of upright structures. Further, the side rail assemblies extend and retract according to changing spacing between the adjacent upright structures as the personnel platform moves along a curved section.

A platform assembly, such as for a utility or communications monopole, can include a central mounting bracket, such as can be configured for mounting about a monopole. One or more or at least three platforms can extend laterally from the central mounting bracket. One or more or at least three lower rails can extend between adjacent pairs of the platforms. One or more or at least three upper rails can be located above respective lower rails. A plurality of vertical mounting pipes can interconnect respective upper rails to corresponding lower rails. Such vertical mounting pipes can support the respective upper rails with respect to the corresponding lower rails. One or more or at least three corner connection plates can extend between adjacent upper rails. A vertical support pedestal can connect at least one of the corner connection plates to an underlying one of the one or more or at least three platforms.

Service platforms are provided for accessing the collapsing frame of blown film extrusion apparatus. The service platforms provide an access platform capable of being placed proximate the collapsing frame of the blown film extrusion apparatus to allow for service, maintenance and/or cleaning of the apparatus.

Modular systems of platforms for use on a ground surface are provided along with methods for the use thereof. The system may comprise: a bottom platform; a booster platform; a railing; and/or a lifter. The system increases the modularity, customizability, portability, and safety of: providing a platform for standing above a ground surface; altering the height above a ground surface of a platform by providing a modular or stackable system of platforms; moving a platform from one place to another along a ground surface; supporting a toolbox above a ground surface; and providing a railing to help prevent a user from falling off of a platform.

A handrail system for a work vehicle has a handrail including a first rail member configured to extend in first direction and a second rail member coupled to the first rail member and configured to extend in a second direction substantially perpendicular to the first direction. The handrail system also has a fold structure configured to couple the handrail to the work vehicle and move the handrail between an upright position and a folded position with respect to the work vehicle. When in the folded position, the handrail has a support surface that is elevated along a central area of the handrail higher than at least one side of the handrail.

A pipe-support system including a pipe-support frame structure having plural, substantially horizontal, pipe-support levels supported by columns including a distribution of side columns uniformly spaced along at least one side of the frame structure, and featuring selectively graduated, support-level-indifferent, lateral-connectivity access for quickly available, removeable, outrigger gravity attachment to the frame's side columns, through gravity catch and hook structures, of modular, outrigger, lateral, worker-platform scaffolding either as individual scaffolding units, or as assemblies of plural, individual units, all such units deriving vertical support through outrigger connections made to the frame structure.
