The features and functions of the rail clips HDGY-TD (1): HDGY-TD series products are used crane beam orbit flexible fixed links. It has to alleviate the wear track top; reduce the impact of the crane on the crane beam; to reduce crane rim wear; reduce the performance of the noise. (2): Since the set elastic composite rubber pad between the rail and the crane beam, not only increases the frictional force therebetween, the rail is difficult to traverse, but also eliminate or reduce the clearance of the rail and the crane beam along the track full long uneven. Thereby improving the condition of the force of the platen bolt. (3): the elastic composite rubber pad asperity-like cross section in the middle, make it reasonable force. Pad above the small rectangular ridges easily deformed pad, not only make easy contact with the rail, but also increase the elasticity of the pad. Played a shock-absorbing role. (4): the elastic composite rectangular groove of the base rubber is set in the direction of the cross-sectional direction of the pad, reducing the overall lateral deformation in the pad after the force, reducing the rubber sheet surface damage caused by the extrusion deformation. Equipped with a steel plate treated, and its structure is very reasonable. 2,000,000 fatigue performance test is still a good performance. Therefore, even after prolonged use, the pad is not damaged. (5): the platen tightening in the crane beam, not loose, easy to wear crane beam. Platen disposed symmetrically in cross section forming a wedge-shaped structure, thereby limiting the track about displacement. (6): the design of the elliptical elongated hole in the platen body, the platen adjustment leeway; fit with slope hole and a retaining block, and can effectively prevent the platen traverse displacement after fastening. Crane rail installation or repair of lateral adjustment convenient. (7): allows trace swing track crane operation. (8): suitable for track length welding.
