Steel structure rail platen is used for elastic fixed connection of concrete crane beam rail. It has the properties of reducing the wear of rail top, reducing the impact of the crane on the crane beam, reducing the wear of the crane rim and reducing the noise.
The elastic composite rubber pad is set between the rail and the crane beam, which not only increases the friction, makes the rail not easy to move, but also eliminates or reduces the uneven gap between the rail and the crane beam along the full length of the rail. Thus, the stress condition of the pressure plate bolt is improved.
The cross section of the elastic composite rubber pad is slightly convex in the middle, so that its force is reasonable. The small rectangular convex strip in the pad is easy to deform, which not only makes the pad easy to contact with the track, but also increases the elasticity of the pad. It acts as a shock absorber.
The rectangular groove of the elastic composite rubber pad is placed in the direction of the section of the pad, which reduces the overall lateral deformation of the pad after force and reduces the damage of the rubber panel caused by extrusion deformation. With the treated steel plate, its structure is very reasonable. After 2 million fatigue tests, the performance is still good. So, even after a long time of use, the pad will not be damaged.
GDGL-1 rail pressure plate is fastened on the crane beam, will not loosen, not easy to wear the crane beam. The symmetrical platen forms a wedge structure in the direction of the section, thus limiting the left and right displacement of the track.
