Product Introduction:
      The rail transit expansion device is divided into ballastless track expansion device and ballasted track expansion device, and the expansion device adopts an upward "Ω" shape design, which makes the waterproof rubber strip easy to install and strong clamping force; The waterproof rubber strip adopts hexagonal double-layer structure, which realizes the role of double-layer waterproofing and reducing slag, and the special-shaped profile made of aluminum alloy has excellent anti-corrosion performance, and the service life is fully guaranteed. Suitable for straight and curved bridges.

The seamless expansion device is composed of fixed plate, displacement linkage, sliding plate, connecting pin shaft, etc., and the displacement of the expansion joint is completed by dragging the sliding plate by the rotation of the displacement link, so as to achieve seamless transition, improve the shortcomings of large expansion gap, and make driving more stable. It is suitable for new rail transit, such as Yunba, empty rail and other bridges.

Project Case:
   Railway: Hainan East Ring Railway, Guiyang to Guangzhou Railway; Rail transit: Lijiang Rail Transit Line 1; Highway: Mozambique road.
