A floor protector for a security access system, comprising a rigid floor assembly having front and rear edges, the floor assembly comprising at least one floor plate and a base mounted underneath the floor plate, the base being at least partially spaced from the floor plate enabling cabling to pass between the two, and elastomeric entry and exit ramps supporting the front and rear edges of the floor assembly; wherein the base has protrusions at its front and rear edges which locate within respective grooves in respective elastomeric ramps, spaced a distance above the lower surface of the ramp, so as to support the base spaced above the whole or a major part of the floor that it overlies.

A cable bus system for the mounting and positioning of high amperature, from low to high voltage electrical power cables transmitting polyphase electrical current. The cable bus system included a ventilated enclosure used to protect electrical cables mounted therein. The enclosure is provided with multiple modular cable trays which are bolted together in a stacked arrangement to form a single multi-level cable raceway. The enclosure is further provided with ventilated top and bottom covers which are secured respectively to the top and bottom of the uppermost and bottom most cable trays to define the enclosed metal circuit. The cable bus system is capable of transmitting the same highest allowable free air cable amperature in both above and underground installations, effectively improving the transmission of electrical power from one end to the other end, in installations where a transition of electrical power from below ground to above ground is either necessary or economically preferable. For the underground portion, the cable bus is installed in the encasement that is uniquely offset vented or power cooled to meet the cable high amperage requirements. The cable bus system is also suitable for high vertical rise installations when utilizing anti cable slip mechanism or technique.

This resin trough body has an approximately U-shape cross-sectional shape that includes a bottom section and side sections on the two sides. Vertical reinforcement ribs are formed at a prescribed interval on the outer surface of both side sections of a trough body of a prescribed length. Further, near the front and back ends of the trough body, horizontal ribs are formed so as to link two vertical ribs. An accommodation space for accommodating a grating lid is formed by a pair of L-shape members being fixed with bolts to a fixing jig that has been attached to the horizontal ribs. The grating lid is accommodated in said accommodation space, and the grating lid is fixed to a bolt fixing section, which is a mounting hole formed in the horizontal plane of the L-shape members.

A cover for a trench of a cable management system has a cover plate. The cover plate is configured in such a way that the cover plate fully covers the trench. The cover further has at least one spring assisted hinge fixed to the cover plate at one end of the cover plate. The at least one spring assisted hinge is configured in such a way that the cover can be attached to the trench by the at least one spring assisted hinge in an openable manner.

A device for connecting a ship to a land-side supply grid includes a rail system having a guide channel, a cover designed to cover the guide channel and formed by a plurality of successive articulated cover plates and a land-side coupling unit mounted on the rail system for travel and designed for receiving a cable-connected ship-side plug. The coupling unit includes a lifting device designed to open the cover by opening the cover plates in a position-dependent manner, and a shield to protect an area of the guide channel opened by the lifting device against falling objects. A cable carrier cable-connects the coupling unit to the land-side supply grid. The cable carrier is arranged lying flat on a side in the guide channel and pivotable about a vertical bending axis.

A branching trough includes side plates forming both side surfaces, and a bottom plate constituting a bottom surface. Both side plates are upright so as to surround the bottom plate. A cross section of the branching trough is U-shaped, and the branching trough is T-shaped in a plan view. A female joining structure for connecting a cable protection member is formed in openings at both longitudinal direction ends of a main trunk section. A female joining structure for connecting a cable protection member is formed in an opening at the leading end of a branch section. A vertical rib of an elbow section of the side plates can serve as a vertical rib inside the female joining structure. On the back surface of the main trunk section and the branch section, a hollow columnar protrusion protrudes downward to a prescribed height from the bottom plate at a prescribed position.

A support column structure includes a vertical support column, a horizontal support column, and/or an oblique support column, which are made of hollow fiber-reinforced resin members having substantially rectangular cross sections. The support column structure further includes a plurality of S-shaped trough fixing support members. Each of the S-shaped trough fixing support members includes an inverted U-shaped first fixing portion and a normal U-shaped second fixing portion, which are joined with each other. By hooking and fixing the inverted U-shaped first fixing portions onto the horizontal support column or the oblique support column, a trough can be placed on the normal U-shaped second fixing portions, thereby obtaining a trough fixing support structure. The present invention can also provide a direction changing structure that includes the trough fixing support structure and various types of angle members.
