Iron source_ Rail shaped fishplate_ 50 to 60 rail joint fishtail clamp plate

The fishtail plate (track joint clamp plate), commonly known as the track clamp plate, plays a connecting role at the track joint. It is divided into light rail, heavy rail, and lifting rail. The fish tail plate, also known as a clamp plate, is used to connect and clamp two steel rails to resist joint shear and prevent rail head misalignment. The structure of the steel rail joint itself is weak, and there is a lot of impact force when the train passes through the joint. Therefore, it is required that the upper and lower parts of the fishplate must closely fit the steel rail and have sufficient strength. Therefore, it is necessary to use steel with good rigidity and toughness for heat treatment when necessary to increase the allowable stress of the fishplate and improve its support surface hardness and wear resistance. The upper and lower sides of the fishplate have slopes, which are consistent with the slopes of the rail bottom and rail head. When the fishplate bolts are tightened, Cannot come into contact with the rail waist. If there is slight wear on the fishplate, the bolts can be tightened again to maintain the firmness of the joint connection.

Fishplate is a connecting fastener used for connecting rails

Light rail has 8KG. 9KG. 12KG. 15KG. 18KG. 22KG. 24KG. 30KG. Light rail fishtail plate, also known as track clamp plate, heavy rail 38KG. 43KG. 50KG. 60KG, and lifting rail QU70.QU80.QU100.QU120, also known as lifting rail diagonal joint clamp plate.

There are two specific types: four holes and six holes.

Classified by material: ductile iron, Q235 rolled, and forged. Different types of steel rails are used in conjunction with different types of fishplates.
