High Quality Hot Rolled U71MN Crane rail QU100 rail For Gantry Crane
General description:
Crane rail also called rail track, steel track, is the main component of crane which ensures that the crane runs along the prescribed route and transmits the wheel pressure to the foundation.The crane railway track usually consists of two steel rails.Depending on the type and application crane, crane rail can be divided into ordinary rail rails, special crane rails (steel crane rails)) or square and rectangular sections of rails.
Qu rail is a special kind of rail track providing a running surface for various types of cranes such as gantry cranes, overhead cranes. It is mainly applied in big projects including wharf, ports and yards.Compared with ordinary steel rails, QU rail has a wide head, a small height, and a large rail waist, which is beneficial to improve the contact with the wheels and suitable for bearing horizontal loads.Small tonnage, medium tonnage crane rail uses P-type railroad rail, large tonnage gantry crane rail uses QU type crane special rail or square rail.

- Rail clamp:The crane rail clamp is a component to ensure that the rail is correctly fixed on the ground.There are main two type of clamp which is welded-base rail clamp and Through-bolted rail clamp.
- Fish plate:Fish plate is used to connect the rails so that the rails maintain a controllable range between the straightness and the vertical height difference in the horizontal direction.
- Rubber pad:The crane rail rubber pad is designed between the sleeper plate and the rail foot, which is made of elastic polyurethane pad, placed between the rail and the sleeper, to protect the top of the sleeper from wear and impact.

Applications:
Ground-operated cranes mainly use ordinary crane rails; bridge cranes often use special crane rails, and other rails are also available. The hoisting trolley has a similar type of rail, which is fixed on the bridge or horizontal boom of a crane. The flange of the steel beam can also be used as the trolley's track. The foundation of the crane track includes concrete, reinforced concrete, slag lining, and metal beams.QU rail is mainly used in crane industry, large-scale projects, terminal hoisting containers, and laying of transportation lines for large machinery and equipment etc., and it's dedicated for gantry cranes.NNATE provides various standard rail track, such as AREMA, GB, BS, DIN, UIC, and other custom rail tracks.
