A wearable body harness has first and second shoulder straps arranged in an X-shape, a back plate on a rear portion of the shoulder straps with the first shoulder strap crossing over the second at the back plate. The back plate includes a pair of lower guide slots, having a first lower guide slot side and a second lower guide slot side contiguous with the first and arranged at an angle relative thereto, and a pair of upper guide slots, having a first upper guide slot side and a second upper guide slot side contiguous with the first and arranged at an angle relative thereto. A first of the pair of upper and lower guide slots route a webbing material of the first shoulder strap. A second of the pair of upper and the pair of lower guide slots route the webbing material of the second shoulder strap.

The present inventive concept discloses to a cleaning apparatus for cleaning both sides of the glass panel. The cleaning apparatus comprises two cleaning components attracted to each other and attached on opposite sides of the glass panel. Each of the cleaning components comprises a body, a cleaning module, and a plurality of magnetic modules. The body has a central portion and a peripheral portion. The body has plurality of grooves on a bottom surface of the peripheral portion. Each of the magnetic modules has a magnetic wheelset disposed in the groove and exposed on the bottom surface of the body. The two cleaning components are adsorbed to opposite sides of the glass panel by the magnetic attraction of the magnetic wheelsets. One of the cleaning components could be driven by a motor to rotate itself and drive the other cleaning component on the opposite side of the glass panel to rotate together.

The present invention relates to a working system, including at least one fastened rope node, at least one mobile rope node, and at least one suspended rope node. The three nodes are connected by using a rope, the fastened rope node is fastened to a surface of a building, the suspended rope node includes at least one working apparatus, and the working apparatus works on a side facade of the building. The mobile rope node can move on the building and change a suspension position of the suspended rope node. In the present invention, safety of a facade working robot is improved, and a working scope is expanded.

A lanyard for attaching a user's harness to a moveable member of a challenge course. The lanyard may comprise an upper section, a lower section, and a midsection arranged therebetween. The upper section may comprise an upper outer loop and an upper inner loop arranged within the upper outer loop, which form an opening configured to attach to the moveable member, and one or more structural connections. The lower section may comprise a lower outer loop and a plurality of lower inner loops configured to receive a coupling device for the harness. The plurality of lower inner loops may be sequentially arranged within the lower outer loop and attached to the lower outer loop via double shear connections.

A fall protection device includes a frame, a rotation unit, a safety belt, and a braking unit. The rotation unit is rotatably disposed in the frame; the safety belt is wound up on the rotation unit, and adapted to be pulled to drive a rotation of the rotation unit. The braking unit includes a braking plate, a braking block, and a stopper. The braking plate is connected to the rotation unit, rotates with the rotation unit coaxially. The braking block is pivotally connected to the braking plate, and includes a stopping part. The stopping part of the braking block can be spun out by a centrifugal force produced by a rotation of the braking plate, and abuts against the stopper to limit the rotation of the rotation unit. The braking block includes an abutted part. The stopper is disposed in a movement path of the abutted part.

A fall arrest lanyard includes a strap body having a fastening end, a securing end, and a relief portion, and restraint relief arrangement being actuated between a normal operated condition and a relief condition. The restraint relief arrangement includes first and second connectors spacedly affixed at the strap body to define the relief portion thereof between the first and second connectors. At the normal operated condition, the second connector is detachably connected to the first connector to shorten a length of the relief portion of the strap body. At the relief condition, the second connector is detached from the first connector, so that the relief portion is able to be fully extended to create a relief length for allowing the user to escape restraint when the user is restrained by the strap body.
