I. Description

MG road bridge gantry crane is mainly used for bridge construction with slow speed.It is composed of gantry frame,winch trolley,long crane travelling mechanism,cab and electric control system. The gantry of a truss structure and having advantages of light structure,strong wind resistance and so on,is composed of girder,upper end girder,leg,lower end girder,travelling trolley and platform railing.The girder is of a triangular truss structure,on which laid rails for crane trolley to transversely move along the main girder.The legs are of a box structure or steel tube structure. The trolley is equipped with windlass,which is compact in structure and light in dead weight. The trolley travelling adopts cycloid gear speed reducer,soft start motor,4 drive in 8 wheels run steadily. The closed cab is employed for operation,where there are adjustable seat,insulating mat on the floor,toughened glass for the window,fire extinguisher,electric fan and auxiliary equipment such as air conditioner,acoustic alarm and interphone which can be furnished as required by users.
