Ridex® Miter Rails for Moveable Bridges
The RIDEX® miter rail system solves your moveable track joint problems.
The
RIDEX® miter rail system also known as the rider rail system is an
improved miter rail system for use in moveable track arrangements such
as bridges of all types, folding cranes, etc. The system features large
expansion capabilities, ease of maintenance and standardized parts.
Description: The system components are rider rail, lift rail, fixed rail, and rail plates and impact pads.
The lift rails and fixed rails are machined from lengths of new rail. One end of each rail is machined to fit the rider rail segment and holes are drilled for web bars and track bars. Web bars are bolted to the rails at the rider rail end to provide additional support of the rail head. All bolting is self locking to prevent loosening in service. The lift rail has a guide block to assure proper alignment at closure.
The rider rail segment bridges the gap between the lift and fixed rails. It is made of hardened alloy steel for longer service life. The rider rail is slightly lower than the running rail at it's ends and slightly higher than the running rail at it's center. This gentle radius serves to smoothly carry the train wheel over the gap between the rails. The rider rail is bolted to the fixed rail and remains stationary.
The rail plates are fabricated and machined from steel plate. They include grooves for the rail foot and holes for bolting to the ties. The grooves are machined with a slant toward track center. Shoulders are provided adjacent to the groove for Pandrol "E" clips to fasten the rail to the rail plates. The fixed rail plate also has a guide shoe to guide the lift rail into position at closure.
Under each rail plate is an impact pad for vibration damping and shock absorption.
The gap between the lift and fixed rails is generally set at several inches depending on bridge configuration and temperature at installation. The expansion capabilities are quite large (+ or - several inches) thus eliminating the need for expansion joints on bridge approaches and reducing maintenance due to track movement. The maintenance of the rider rail system is simple. As the rider rail wears, it is easily replaced without affecting other components of the system.
The rider rail system can be used on all types of moveable bridges. The system as shown is for lift and bascule bridges. The swing bridge system has longer lift rail plates with guide shoes and openings to accommodate the rail lift mechanism. Additional holes in the rail plates are added for rail down signal switches.
