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.

The present invention relates to utility support apparatus (30). The utility support apparatus (30) comprises first (32) and second (34) elongate arrangements each configured towards a proximal end to be attached to a structure so as to depend from the structure. The utility support apparatus (30) also comprises a holding arrangement configured to, in use, hold utility distribution elements. The first and second elongate arrangements (32, 34) are mechanically coupled to the holding arrangement at spaced apart locations on the holding arrangement. Each of the first and second elongate arrangements (32, 34) is mechanically coupled to the holding arrangement at a location on the elongate arrangement spaced apart from the proximal end. Each of the first and second elongate arrangements (32, 34) comprises a first aperture (42) towards the proximal end to provide for attachment to the structure and second and third apertures (44, 46) spaced apart from the proximal end, the second and third apertures (44, 46) providing for mechanical coupling to the holding arrangement. The first, second and third apertures (42, 44, 46) lie in the same plane.

A walkway system comprising a plurality of support assemblies, each having a pair of spaced apart beam support plates on an upper side thereof, and a plurality of pairs of beams. Each pair of beams is supported by pairs of spaced apart beam support plates of at least two support assemblies. A plurality of cross members extend between lower portions of the pairs of beams. The cross members are configured to support one or more cables resting thereupon. A plurality of decking members extend between the pairs of beams. The decking members are secured to upper sides of the beams. The cross members, beams and decking members cooperate to form a partial enclosure for the cables, thereby eliminating the need for a separate cable tray.
