A telescoping work platform utilizing three planks that are slidable to each other allows for a longer maximum length for use while providing for a shorter collapsed length for storage all while providing necessary structural support.

A stocker includes a transporter that travels through a traveling space within a stocker and transports an article, a pair of rails that flank the traveling space extend in parallel or substantially in parallel in a horizontal direction, platforms movable along the pair of rails, and a housing provided on a stocker outer side of a door that separates an inside and an outside of the stocker, and that houses the platforms. The pair of rails extend from the inside of the stocker to the housing through an opening directly under the door. At least one of the platforms includes a fence in an upright standing manner and an upper end of the fence is higher than an upper end of the opening. The platform that includes the fence extends across the inside of the stocker and the outside of the stocker via the opening while the fence is arranged on a stocker inner side.

Apparatus, devices, and methods relating to a mechanical proximity sensor for a slidable extension. An illustrative apparatus may comprise an elevated platform and an extension slidably extendable from the elevated platform toward a workpiece. The apparatus also may comprise a probe coupled movably to the extension. The apparatus further may comprise an indicator connected to the probe and configured to rotate from a first orientation to a second orientation in response to engagement between the probe and the workpiece as the extension approaches the workpiece. The indicator may be configured to complete rotation from the first orientation to the second orientation when a leading edge of the extension is located at a predetermined distance from the workpiece.

The invention relates to a scaffolding system with at least one scaffold decking (30). The scaffold deckings (30) preferably have identical fittings (10) which are connected to decking profiles (32) of different heights, in particular in an identical manner. Particularly preferably, the scaffolding system has at least two scaffolding deckings (30), each having identical fittings (10) but decking profiles (32) with different maximum heights (H.sub.32), wherein further preferably the length (L.sub.32) of the decking profile (32) with lower maximum height (H.sub.32) is shorter than for the decking profile with higher maximum height (H.sub.32). In a further preferred embodiment of the invention, the scaffolding system comprises at least three scaffold decks (30), each having identical fittings (10) but decking profiles (32) with different maximum heights (H.sub.32), wherein further preferably the decking profiles (32) are of different lengths and have greater maximum heights (H.sub.32) with increasing length (L.sub.32).

An adjustable telescoping plank preferably includes an outer plank, an inner plank and a drive device. The outer plank includes a substantially rectangular cross section. The drive device is retained on an inside of substantially a first end of the outer plank. The inner plank includes a substantially rectangular cross section. A lead screw nut is retained on a first end of the inner plank. The inner plank is sized to be received by an inner surface of the outer plank. The drive device preferably includes a lead screw, a drive gear, a driven gear and a drive shaft. The drive shaft rotates the lead screw through the drive gear and driven gear. The lead screw engages the lead screw nut to axially move the inner plank relative to the outer plank. A contact member may be pivotally retained on a front of the inner plank.

A plank assembly for a scaffolding includes a main plank and at least one extender plank adapted to telescopically extend or retract relative to the main plank. The at least one extender plank, when extended relative to the main plank, provides an additional support platform for a work crew.

A work platform for working on a roof area of an electrified vehicle, including a platform. The platform has first platform elements, which form a work plane, and in each case have a longitudinal extent within each case two mutually opposite long sides, and a plurality of second platform elements, which are arranged along at least one of the long sides of the first platform elements and can be transferred between two positions with respect to the first platform elements. The second platform elements form a fall protection device in a first position and a continuation of the work plane of the first platform elements in a second position. Furthermore, a maintenance device having at least one such work platform.

A work platform includes a plank which telescopes to a desired width. The work platform includes a first leg assembly rotatably attached adjacent to a first end of the plank. The work platform includes a second leg assembly rotatably attached adjacent to a second end of the plank. The work platform includes a first linkage attached to a first leg of the first leg assembly. The first linkage may be a first hook or a first strap assembly for securing the work platform to a first support structure. A method for using a work platform. A method for producing a work platform.

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 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.
