A monorail assembly includes a first scaffold system comprising at least one framework member being an elongated structure having a bottom chord and a plurality of panel points along the bottom chord; at least one monorail beam; and at least one bracket structure configured to secure to the at least one framework member at or about at least two panel points and to the at least one monorail beam.

A jump suicide prevention device includes a pair of link parts disposed to face each other in a longitudinal direction of the bridge railing, a roller part including rotation parts on opposite sides thereof in the longitudinal direction to be rotatably coupled between the link parts, leg parts respectively coupled to lower ends of the link parts by fastening members, and resilient members installed between end portions of the link part and the leg part with being interposed therebetween to control vertical movements of the link part. As a jump suicide prevention device capable of preventing a suicide jumper from jumping over the upper portion of the bridge railing, the device may prevent incidents of jump suicide from bridge railings due to the configuration of the roller part which rotates while vertically pivoting according to the weight of the suicide jumper.

A cable climbing robot includes a climbing front body and a detection body. The climbing front body includes a front body rack, duct propellers, a front body clasping units and a front body control modules, the duct propellers are mounted on the outer side of the front body rack; the front body clasping unit includes a front body clasping electric motor, a front body clasping transmission component and a front body clasping member; the front body clasping electric motor is fixedly mounted on the front body rack, and the front body clasping electric motor drives the front body clasping member via the front body clasping transmission component; the front body control module is mounted on the front body rack, and the front body control module is electrically connected to the duct propellers and the clasping electric motor.

An adjustable suspension assembly for suspending a lower structure such as a platform from an upper structure such as a portion of a bridge. A chain, which is attachable at one end to the upper structure or to an end of a cable which is attachable at its other end to the upper structure, is attached at its other end to a device. The device, which is attachable to the lower structure, has a pair of aligned apertures in its side walls for receiving pins. The pins are spaced to receive a thickness of a chain link but not to receive a width of the link, whereby a selected link to achieve a desired lower structure height may be cinched between the pins. When the chain is attached to a cable, the cable has an eyelet formed by folding an end portion of the cable back over the cable and swaging the cable end portion to the cable. The chain is attached to said eyelet by receiving the end portion of the cable in one of the chain links before the cable end portion is swaged to the cable.

The invention includes a work platform and support system that includes a hub and joist configuration, wherein the hubs and joists are capable of articulation, or pivoting. One method of installation allows for sections of new work platform system to be extended from an existing suspended work platform system. The system is also capable of supporting, without failure, its own weight and at least four times the maximum intended load applied to it.

A scaffolding to be fastened to a bridge or the like deck structure comprises a boom system (2) for supporting the working platforms and the support structures needed for the work and for fastening the boom system of the fastening body (1) to the upper surface of the deck structure. The boom system (2) is connected to the fastening body via a swivel quadrangle (3, 6, 11, 12).

The present invention relates to a suicide preventing fence, and, according to an embodiment of the present invention, the suicide preventing fence comprises: a plurality of pole parts provided standing upright from the ground surface at predetermined intervals; a plurality of linking parts which are formed in the shape of pipes and horizontally link the spaces between the pole parts; rotating bodies which are formed with an internally hollow abacus bead shape and are provided on the outer circumferential surfaces of the linking parts; bearings which are provided on the outer circumferential surfaces of the linking parts, positioned in the centers on the insides of the rotating bodies; and rotating bolts which are provided on the outer circumferential surfaces of the linking parts and are inserted in through-passing regions on both side surfaces of the rotating bodies so as to rotate together with the rotating bodies. Consequently, the invention makes it possible to prevent suicide since the rotating bodies are provided on the fence and cannot be easily grasped by anyone attempting to pass over same.
