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 moveable wing gantry for servicing a wing of an aircraft is configured to be positioned around a wing of an aircraft to provide access to overwing and underwing surfaces of the wing of the aircraft. The wing gantry includes a service deck positioned underneath the wing of the aircraft. An operator platform is moveably attached to the service deck and operable to move along the length of the service deck. A chair support is moveably attached to the operator platform and operable to move across the operator platform in a direction substantially perpendicular to the length of the service deck. The wing gantry includes a pivotable span platform positioned above the wing of the aircraft and pivotable between a raised position and a lowered position. The wing gantry is customizable to different aircraft wing types and styles.

A cage for surrounding a section of a work area of the top of rolling stock includes an inboard side, an outboard side, a front end section and a back end section. The inboard side of the cage is attached to an associated deployment apparatus. Each of the two sides can define a pair of fence notches to slide over the rails surrounding the work area. Each of the two end sections can define an inboard notch and a center notch. Some embodiments of the end sections can define an outboard notch that includes a self-adjusting straddle. The cage can be provided as part of a portable fall protection device that includes a telescoping positioning mechanism.

Disclosed is an arrangement including a staircase as well as walkway systems. The staircase includes a transitional member, and the walkways incorporate grate supports in order to facilitate the connection to adjacent structures. The arrangement also utilizes angled members which are configured with a reinforced flange existing in a dimension that has higher load requirements than the other flange. A novel step configuration is also disclosed.
