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.

A work platform includes a frame and a deck. The frame has a plurality of frame members that are interconnected. The frame members define a trough that extends a length of the frame and is configured to accommodate a refueling boom of an aircraft such that the refueling boom extends through the frame within the trough. The deck is mounted to the frame to provide a stand. The deck includes a first deck panel and a second deck panel spaced apart from each other to define an opening to the trough.

An improved building access system includes a turntable having an upper surface and a lower surface, a main tower attached to the turntable's upper surface, a boom tower pivotally attached to the turntable and disposed so as to form an angle with the main tower, and a balancing tower also pivotally attached to the turntable and also disposed so as to form an angle with the main tower. It also includes means for changing these angles between the main tower and, respectively, the boom tower and the balancing tower, and a cathead pivotally attached to the end of the boom tower which is opposite the end attached to the turntable. The inventive apparatus also includes pressure sensing devices located and disposed so as to measure the pressure at each mounting point where the main tower is attached to the turntable, along with one or more leveling rods disposed so that, as the boom tower is raised upwardly and the angle between the main tower and the boom tower decreases in value by an associated amount, the angle between the cathead and the boom tower decreases in value by the same amount. The turntable may further include at least one support arm configured so that the bending forces experienced by the turntable are transferred to a larger diameter support structure. The invention also includes an elongated beam member which is especially useful for forming box beams, which member has a pair of symmetrical planar side elements which are perpendicular to each other and which are also connected together by a diagonal element.

A stabilization component is described for a lightweight scaffold having a pair of ladder frames supporting an adjustable platform. Each ladder frame has two vertical supports connected by cross members. An outrigger, which is formed as a triangular frame, is releasably connected to each vertical support via a channel that fits around the vertical support and one or more mechanical fasteners. One or more ground-engaging members are removably secured to the outrigger. When installed, the outriggers increase the footprint size of the lightweight scaffold thereby reducing shaking and swaying of the lightweight scaffold.

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.
