CDP Slide Plate Roller System
A roller system that provides support to the switch blades during traversing operations but allows the blade to be totally supported under loaded conditions.
This is a new generation product developed from theoretical research by VAE and CDP Europe. The plates have been used extensively in Europe and England. The plate roller assembly has formal DB Rail approval in Germany. They have been installed on turnouts with axle loads from 15 tonnes to 35 tonnes.
CDP Roller Plates have been installed in tangential turnouts throughout Australia. Standard 53kg and 60kg flexible full depth switch assemblies have also been installed with CDP Slide Plate Rollers.
CDP Rollers have now been installed in the Heavy Haul area and are now used on Area 136 Tangential Switch Assemblies.
The CDP Slide Plate Switch Roller is a switch roller developed for use with asymmetric switch blade material. There are also designs developed in Australia for full depth switches to suit both 60Kg and 53Kg under cut blades.
The switch roller assembly comprises a cast base plate that has the inner stockrail IBAV fastening system and a pandrol clip on the outer side. The plate is machined to accept the roller bracket assembly and has a series of threaded holes to allow for infinite adjustment of the rollers.
The complete roller assembly comes with a cast bracket and two hardened stainless steel rollers attached with stainless steel pins.
The roller assembly is attached to the plates with bolts that allow the rollers to be adjusted to the correct position on a machined section of the base plate. The brackets can be adjusted to any position to suit the blade location.
The actual quantity of plate roller assemblies required for each application is determined by the switch configuration and the type of operating rodding attached.
The same roller assembly and adjustment procedure is used on various chair plates for both tangential switch blades and standard full depth chair plates.

• Easily set and adjusted
• Minimal maintenance
• Low risk of damage from tamping machines
• Lubrication free design
• Switch blade is seated on support plates when in the home position.
• Roller operation available for most type of switches
