Transmission mechanism slotted J-75 multi-drive mechanism type bridge expansion is determined by the control arm, joystick and other ancillary pieces of composition. Joystick from the beams in through the web, and a cylindrical bearing where co shown in Figure 5-4. The mechanical motion transmission mechanism as follows: embedded in the body of the box beam driven control arm bridge expansion joints, control arm forcing the lever rotated D160 bridge expansion joints installed, push the lever to slide axially along the bridge beams, beams and prompting the lateral longitudinal beams parallel movement. By Yan-shaped rubber seals rubber and stainless steel clamp bar and clip blocks. Side of the block is about to rubber toothed pattern pressed into the inner recesses of the clip, clip a certain distance of the outer edge of the vertical sleeve with clip every block, with a stainless steel bolt through the clamp block, the rubber grip on the stringer flange below, shown in Figure 5-5, represented by freeway highway sprung up, a sharp increase in road traffic, axle vehicle traveling speed and the vehicle on the road is growing, people are driving comfort other requirements are also increasing the use of thick steel plate welded longitudinal steel beams (currently used in the overall shape of profiled steel, referred stringer) and parallel to the bridge axis transverse support girder (referred to as beam) formed. Stringer is divided into the side stringers and stringers XF-type bridge expansion joint device has a cross-section of different forms of bridge expansion joints are oblique-supporting device is built by the iron Academy of Railway Sciences, Hebei Hengshui City Rubber Co. shares Company and Shijiazhuang traffic Survey and Design Institute in 1993 jointly developed the Modular series. New bridge for all kinds of bridge expansion joints using D60 price, but also for telescopic device to replace the old bridge into the selection. This product is the use of chain-link connection mechanism, with good uniformity stretch and won in 1999 the Ministry of Communications Science and Technology Progress Award ho-card bridge expansion joints price _ Golmud _D60 bridge by bridge expansion joints Hao-engineering rubber available.
