Railway Turnout

A railway turnout or switch is a mechanical installation enabling trains to be guided from one track to another, such as at a railway junction or where a spur or siding branches off.

The turnout consist of a pair of linked tapering rails, known as points (switch rails or point blades), lying between the diverging outer rails (the stock rails). These points can be moved laterally into one of two positions to direct a train.

Rail Sleeper.png
Railway Sleeper

​A railway sleeper, railroad tie, crosstie, railway tie, is a rectangular support for rails in railroad tracks. Generally laid perpendicular to the rails, ties transfer loads to the track ballast and subgrade, hold the rails upright and keep them spaced to the correct gauge. Railroad ties are traditionally made of wood, but prestressed concrete is now also widely used, especially in Europe and Asia. Steel ties are common on secondary lines, plastic composite are also employed.

Coupler System

Coupler system, as well as called draft gear system is a mechanism system for connecting rolling stock in a train.

Rubber Spring Train.png
Conical Rubber Spring

The conical spring is named from the shape of the rubber layer design. The structure is designed with layers of rubber bonded to metal. The conical spring is often installed in pairs in one axle box and provides three directions of stiffness; vertical (longitudinal) and horizontal (lateral and longitudinal). The vertical stiffness is soft and gets progressively stiffer in order to prevent derailment. The longitudinal and lateral stiffness is important for transferring the braking and traction force as well as for the stability of the rail car.

Features

  • Our manufacturer are able to design different mechanical structures to meet different stiffness property requirements.

  • Furthermore, we are excellent at designing products with low creep, and can generally minimize creep to around 15% over the product life time; industry averages are between 20-25%. We predict creep and design products to compensate for it.

Specification

  • We have our own design products and general international standard products which are usually used all over the world

  • Customer could send their specification and design to us

  • Our conical rubber spring expected life time are 5-6 years

Roller Bearing.png
Rolling Bearings

Rolling bearings support and guide rotating or oscillating machine elements – such as shafts, axles or wheels – and transfer loads between machine components. They provide high precision and low friction and therefore enable high rotational speeds while reducing noise, heat, energy consumption and wear. Rolling bearings are cost-effective and exchangeable machine elements that typically follow national or international dimension standards. 

Additional

  • Roller bearings, including tapered roller bearings, spherical roller bearings and cylindrical roller bearings, are increasingly being selected to replace plane bearings in rolling stock axles based on the particular merits of each type.

  • We supply all the range of railway axle bearings, such as Tapered Bearing Units (TBU), Compact Tapered Bearing Units (CTBU) for the applications including:

Features

  • We follow general international standard products which are usually used all over the world
