An adjustable pier assembly for use with a railroad control house includes a frame member, a movable sleeve having a pair of flanges rigidly attached to an extending sidewardly therefrom, and a pair of fine adjustment threaded members having associated hardware. By adjusting an initial adjustment bolt, an initial "rough" height adjustment is provided between the pier and the sleeve. A final fine adjustment is then provided between the sleeve and the frame of the apparatus by adjusting the location of the fine adjustment nuts which combine to capture the flanges along the lengths of their respective fine adjustment bolts. When four adjustment pier assemblies are used on four corresponding corners of a railway control equipment house, quick initial setup followed by fine leveling adjustment in two axes is readily provided.

The traffic cross-guard reflective mat is adapted for use by traffic officers. The traffic cross-guard reflective mat is a highly visible reflective mat that is designed to attract attention from a distance. The traffic officer stands on the traffic cross-guard reflective mat in order to benefit from the attention drawn by the traffic cross-guard reflective mat. The traffic guard reflective mat comprises a mat, a plurality of reflective surfaces and a plurality of lights.
摘要:
A transit boarding platform panel comprising a base portion formed from a reinforced composite polymer. The base portion has a top deck and a bottom plate, a first end, a second end, a first side and second side. Between the top deck and bottom plate are a series of internal longitudinal and cross support members. The top deck has a central section and opposite end sections. Detectable warning tiles are mounted to the top surfaces of the end sections. The top surface of the central section has a slip resistant surface. In the preferred embodiment the slip resistant surface consists of a non-slip walking surface coating applied to the top deck. The slip resistant coating should be resistant to the effects of ultraviolet radiation, temperature changes and corrosive elements such as acids, alkalis, salts, phosphates, organic chemicals and solvents such as mineral spirits, gasoline etc. It should also preferably be sufficiently hard to protect against abrasion, chipping, scratching or marring. Positive drainage is provided by the top deck being typically symmetrical about the mid-point line tapering from the mid-point to the ends of the panel to facilitate runoff of any precipitation and prevent standing pools of water. Positive drainage is further provided by the interface between adjacent panels utilizing a ship lap configuration with a drainage channel beneath the joint between adjacent panels.

A temporary ramp having a plurality of segments coupled together by way of interlocking mating shapes located along the edges of adjacent ramp segments. Hinges couple adjacent ramp segments together. Fastener openings defined in the ramp segments allow a fastener to be fixed with the underlying roadway to help secure the ramp segment in position.

A vehicle access control system includes an elongate, generally hollow, generally planar base platform having a first and a second distal end. A generally hollow enclosure is atop the base platform. A first lift gate is intermediate the enclosure and the first distal end of the base platform, while a second lift gate is intermediate the enclosure the second distal end of the base platform. A first lift arm is pivotally coupled to the first lift gate and extends generally perpendicularly away from a longitudinal axis of the base platform. Likewise, a second, opposing lift arm is pivotally coupled to the second lift gate and extends generally perpendicularly away from the longitudinal axis of the base platform. The base platform is configured for direct contact with a mounting surface. In addition, the vehicle access control system is transportable as a unit.
