Rail Base Plate

Rail base plate is also called tie plate or sole plate, and is used in rail construction to support the rails.

A tie plate, base plate or sole plate is a steel plate used on rail tracks between flanged T rail and the crossties. The base plate increases bearing area and holds the rail to correct gauge. They are fastened to wooden ties by means of spikes or bolts through holes in the plate.

The part of the plate under the rail base is tapered, setting the cant of the rail, an inward rotation from the vertical. The usual slope is one in forty (1:40 degrees ). The top surface of the plate has one or two shoulders that fit against the edges of the base of the rail. The double-shoulder type is currently used. Older single-shoulder types were adaptable for various rail widths, with the single shoulder positioned on the outside (field side) of the rails. Most plates are slightly wider on the field side, without which the plates tend to cut more into the outsides of the tie, reducing cant angle.

Our rail base plate made using either casting iron or casting steel for customers to choose, which depending on the load and the type of rails. Bolt able as well as weld able clips can be applied. Rail base plates are generally used to take the load of rail and distribute the load to the sleepers offering proven economies. We manufacture all types of rail base plates suitable for various rail sections, for use on wooden, steel or concrete sleepers and ballast-less tracks used with elastic fastenings on wooden sleepers and 'K' type fastening system.

Cast iron base plate can be the welded or fabricated type, depending upon the customers requirements. Our rail base plate can be made to suit various rail section, i.e. UIC 60, UIC 54, RN 45, 90 A, etc.

Rail base plates are the uppermost component of a crane rail or track support system. The primary function of a base plate is to provide the rail with a flat, smooth resting surface while allowing for vertical alignment of the rail system. Base plates are secured by anchor bolts, also known as holding down Bolts. Soleplates are typically installed with a layer of grout cast beneath, which fills the void between the soleplate and the concrete foundation.

Below are some examples of rail base plate we have manufactured over the last several years.

We produce and supply rail base plate according to AREA and DIN standard..We are a leading rail base plate manufacturer in China. We can also make other rail fastenings such as rail clip, railway screw, plastic dowel, rail pad, railway insulator, rail fish bolt, railway base plate, rail anchor, railway shoulder, rail bolt, flat and spring washer, fastening system of E type/SKL type/KP type/Nabla type.
