Rail fittings are part of the railway line. As a whole engineering structure, the track is laid on the roadbed, and it plays the guiding role of the train operation, which directly bears the great pressure of the locomotive vehicle and its load.Under the dynamic function of the train operation, the component part of it must have sufficient strength and stability, and ensure the train in accordance with the relevant provisions of the highest speed, safe, smooth and continuous operation.

Tie rod?The standard tie rod is a rod that connects two rails at the bottom of the rail to improve the transverse stability of the rail and improve the track's ability to keep track. Some lines have track circuits, which are separated by insulation parts.

Rail switch?A switch is a line connecting equipment that transfers a locomotive from one track to another, usually in a large number of stations and marshalling stations. With a switch, the ability to pass the line can be fully realized. Even if it is a single line of railway, laying a fork and building a fork that is larger than the length of the train, you can turn on the train.

Sleeper?it is also called wooden pillow, anti-corrosion wooden pillow. It is a load-carrying material used for laying and carrying equipment for railway and dedicated track walking equipment. Good elasticity, light weight, simple production, good insulation performance. The fastener and the wooden pillow connection are simple, the laying and maintenance and maintenance, transportation is convenient, there is a large friction coefficient between the wooden pillow and the gravel road slag.

Steel tie plate?The gasket is divided into the rubber gasket and the steel plate, the main function is to cushion under the track, in the operation process mainly plays the role of damping.

Train track spikes?The spike is mainly used for the connection of rail or pad and wooden pillow, which is a fastener for connecting rail and sleeper or pad and sleeper.It is usually divided into five kinds: ordinary spike, frost damage screw, thread spike, spring spike, screw spike. With the technology of hot rolled steel, the shape of the lower part of the nail and the shape of the rail bottom are suitable. The surface of the nail rod is clean, and there is no crack in the joint of the nail head and the nail, and the tip has no burrs and folds. There is no bubble in the surface of the spike, and the cracks are used in the coal mine and road transportation.

Rail clip?The rail clip is also known as the welding type pressure rail, welding type rail fixation device, steel girder rail, welding type pressure plate, regardless of the name, its function only one is to press the fixed steel rail. It is usually welded to steel beams and sometimes used in steel plates embedded in concrete.

Rail joints?Commonly known as rail fish plate, plays a role of connection joint in an axle, plywood is a kind of used rails and rail connection using the connection between the fasteners, generally have the fish bolts, form a complete set of plywood and weight of the different price is different also, have the effect of connect rails, facilitate after the demolition of reuse, also have no direct connection plate welding.

Platen /G514 platen?The pressure plate is used to press the fixed steel rail and the steel beam and the concrete beam or the ground parts.Commonly used with hexagonal bolts or embedded bolts. The pressure plate is used directly through the embedded bolt on the ground, and the rail is welded on the steel girder. The G514 special pressure plate is used for drilling holes on the steel girder. The distance of drilling to the hole is 80mm.

Fishtail bolt?The fishtail bolt and the presser are used together, which is usually embedded directly in the cement pillow, which can play the role of fastening the rail.Its shape is not with hexagon bolt, the root is half round head, the inside of round head has two bulges. It is called a fishtail or fishtail bolt because of its connection to the rail fishtail plate.
