This is according to the crane model to select mainly refer to the largest crane of the orbit wheel pressure and minimum wheel pressure to calculate the required size of the orbit and the wheel of the crane selected size
The crane runs the route from the rails, which ensures that the crane runs along the specified line and delivers the wheel pressure to the base.The orbit is usually composed of two rails, which carry heavy loads, such as the track of a large cable crane, which consists of several rails.According to the purpose and type of crane, can use ordinary railway rail, crane rail (see figure] [crane rail) or square and rectangular cross section of rail.Special compared with the ordinary railway rail, crane rail head width, height, rail waist, is conducive to improve contact with wheels, and conducive to under horizontal load, but the price is more expensive.The cranes that run on the ground are mainly made of ordinary railway rails;The bridge crane is commonly used for steel rail and other rails.There is a similar type of track in the crane, which is fixed in the bridge of the crane or the horizontal arm, and the flange of the girder is the track of the car.The base of the crane track is concrete, reinforced concrete, road slag sleeper and metal girder.The rail joint should ensure that the crane runs smoothly and reduces the impact.Track the laymen, gauge and the high and low two rail has a great influence on the running performance of crane, must according to the specification requirements of accuracy for installation.The rails should be fixed in case the foundation slides.The track may be deformed in the course of the process, and the steel rail head is liable to wear out, so it is possible to make the connection between the track and the foundation so as to adjust the replacement.
