(www.htgcxj.com) Hebei Hengshui, a leader in site construction materials, over the years, the company is implementing scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. In Hao-engineered rubber leadership with the staff warmly welcome all inquiries negotiations to create Hao-engineered rubber a better future. Bridge expansion joints actuator drive mechanism bridge expansion joints slotted J-75 multi-type bridge expansion device is controlled by the arm, joystick and other ancillary pieces of composition. Joystick beamed across the web from the GQF-C80-type bridge expansion joints, where it and a cylindrical bearing with expansion joints, shown in Figure 5-4. Mechanical movement bridge expansion joints transmission mechanism will be as follows: the beam embedded in the body of the box led to the control arm, control arm forcing the lever rotates, pushing the joystick to slide axially along the bridge beams, beams, while promoting the lateral stringers parallel movement. Bridge expansion joints rubber seals by Yan-shaped rubber strip with stainless steel clip strip and clamp blocks. Side of the block is about to rubber bridge expansion joints with tooth pattern is pressed into the grooves inside the folder of the GQF-C40-type bridge expansion joints, clip strip the outer edge of the longitudinal distance intervals set to clamp blocks GQF-F40-type bridge expansion joints, with stainless steel bolt through the clamp block, clamped under the rubber strip on the stringer flange, as shown in Figure 5-5 sectional bridge expansion joints are arranged as shown in Figure 5-11. Its series of specifications and dimensions parameters in Table 5-4 of the cases.
