Upper pressing plate Upper pressing plate is the key part in the system which passes the upright force from rail and side force directly, and fixes the rail on both directions. Main body of pressing plate adopts casting process. At the contacting edge with rail, it applies vulcanized rubber which could fix the rail on both lateral and upright direction flexibly. And the material feature of pressing plate is vibration reduction and corrosion resistance. The area where the pressing plate contacts the rail is much bigger than the traditional pressing plate. It could fix the rail better.

Pre-imbedded plate is the boundary surface between equipment and foundation. It bears acting force and partial side force of upright direction from whole equipment. At the same time, pass all this acting force to foundation. Therefore the performances of pre-imbedded plate act a key role to the entire system. Characteristic of pre-imbedded plate with different material indicated as right picture.

Sub-plate under rail is the key part during this system which passes the acting force from rail to base. Main material is high molecular with high bearing load capacity. It could erase concentrate stress between steel rail and base. It could protect steel rail, base plate and foundation prolonging service time of entire rail system.According to different working condition and application field, material base plate is quite different correspondingly. In term of thermal condition, sub-plate under rail can be classified as: R P (normal temperature type 5-100℃) RPF(high temperature resistance 5-200℃ ) RPI（low temperature resistance -50℃-100℃） In terms of bearing capacity, base plate can be classified as R(light load) P(heavy load) PR(composite type)

Rail corner sub-plate is between pressing plate and steel rail which adopt high molecular material. The inner arc of corner backing plate laying on the surface of rail; the outer arc is laminated on vulcanized rubber of pressing plate. When pressing plate fix well, through corner backing plate constrain degree of freedom from both side direction and upright direction; release longitudinal degree of freedom. When heat expansion and cold contraction occurred on rail, longitudinal deformation could be released. The rail breaking threat could be avoided.

Height adjustable sub-plate (for settlement project) Height adjustable sub-plate for base(settlement≤10mm) Material: high molecular material. specification:1mm,2mm ,3mm ,4mm, 5mm, 10mm, 15mm, 20mm, 25mm, 30mm, 40mm, 50mm etc.. According to the height of settlement, it could be adjusted by selecting most propitiate specification. It could be raised 100mm maximum. Note: we suggest maximum layers be better less than 3. If it is applicable, refer to the first method on page NO.3

Height adjustable sub- plate(100mm＜settlement≤150mm) Material: high molecular material Specification: 25mm When height of settlement more than 100mm,the plan is supposed to choose according to actual settlement height. If the settlement height is within 125mm, a 25mm-adjustable platemaybe inserted underneath base plate.(refer to second method on page 3). The rest settlement can be compensating by height adjustable base plate. If the settlement range from125mm to 150mm, two height adjustable base plate should be put under base plate, total 50mm.(refer to 2method on page NO.3). The rest can be adjusted by height adjustable sub-plate.
