Description

Technical Field

[0001] This utility model relates to the field of beam transport vehicle technology, specifically to a travel auxiliary device for beam transport vehicles. Background Technology

[0002] A girder transporter is a specialized vehicle used to transport precast reinforced concrete bridge deck beams from a prefabrication plant or bridge site to a bridge erecting machine. These vehicles are available in rail-mounted and wheeled types. They mainly consist of dozens of drive and driven wheels, a frame, a cab, a control system, and auxiliary devices. They are auxiliary equipment for bridge erecting machine construction, but existing girder transporters often require auxiliary devices to help move the precast beams onto the upper part of the transporter.

[0003] However, most of the current auxiliary devices for beam transport vehicles do not have the function of clamping the precast beams during the movement of the beam transport vehicle. The precast beams are prone to shaking, which reduces the stability of the device. In addition, the installation of most auxiliary precast beams is complicated, which reduces the convenience of installation. Utility Model Content
