Product introduction
Move girder cranes mainly consist of the main girder, rigid leg, flexible leg, crane traveling mechanism, lifting mechanism, electrical control system, hydraulic system, cabin, handrail, ladder, and platform, etc.
Move girder cranes adopt tire line technology to finish handling all beams in the preset field and can realize many walk line models, such as straight, oblique and crosswise. Its advantage is strong adaptability, high efficiency, small occupied area and no need to lay the rail. In the construction of the high-speed railway in China, this kind crane is used to lift, handle and load the beam by most preset field.
Move girder cranes, used to lift, handle, load beam in the preset field when the high-speed railway weight is below 1000t. It adopts tired rail model running model and with power generating set to provide power. It can travel along the laid rail and its running mechanism can rotate 90 degrees to realize straight travel and crosswise to finish handling all beams in the preset field.
