Double beam crane is used indoors, will be equipped with the corresponding length of the track, the crane track is generally cast steel, their length is limited, are connected through the track joint two, their role is to facilitate the machine or car movement
Generally speaking, we need to do the corresponding processing of the track joint, which is to make the crane or crane car through the track as far as possible will not encounter resistance or turbulence to achieve a smooth sliding transition, the following is to introduce the double beam crane rail installation technical specifications and guidance:
Crane rail is of course the international standard, is to meet the requirements of the relevant national standards; Is to take into account the influence of rail thermal expansion and contraction, after welding is the need to have a gap, the size should be controlled in the range of 15-18mm, but also can not be less than 12mm; Is the order of rail welding, first of all, must be welded to the bottom, and then welded to the waist, is the rail head. So the welding technique is layer by layer by channel surfacing treatment, around the repair treatment. Heat treatment after welding is also necessary, of course, is some grinding effort, as long as ensure that the track joint and the overall track to keep consistent smooth, neat is completed.
