A rapid release and rapid install latching member for use with ladder cages to couple the cage rings is provided wherein the latching members are capable of retaining the cage ring connecting members thereon without the use of external fasteners. The latching members are designed such that they may be removed from or installed on the ladder cage while the ladder cage is installed at the work site or otherwise for quick and easy repair or replacement. An exemplary ladder cage contains a plurality of ring members having a plurality of latching members interspaced around the circumference thereof, with adjacent ring members being coupled to each other through the interaction of cage ring connecting members with the latching members.

Provided is a modular work platform including multiple modules for assembly about a tuned mass damper in a wind turbine, whereby the multiple modules are a first base platform, a second base platform, a first base connecting railing, and a second base connecting railing, whereby in an assembled state of the modular work platform, the modular work platform includes a platform opening for the tuned mass damper, wherein the platform opening is formed between the first base platform, the second base platform, the first base connecting railing and the second base connecting railing. A system including the modular work platform and a fixture for the tuned mass damper in the wind turbine, whereby the modular work platform is connected to the fixture is also provided.

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 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.

A scaffold toeboard assembly including a toeboard frame having a toeboard coupled to a riser with a first and second end, with a lift handle coupled to the first end, and a toeboard coupled to the second end. The assembly further including a support frame having a vertical support with an attachment member configured to couple to a scaffold swing gate, wherein the riser is slidably coupled to the vertical support.

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.
