Highway/Railroad Bridge Erector
The TJ180 Highway/railroad bridge erector is composed of bridge erector, beam transport trailer and reverse installation gantry. So the product can achieve reverse installation, transport and erection of beam plate. It is the complete set of equipment for the beam erection operation of railroad. The equipment can be used to erect the T-box beam for new railroads and passenger and freight railway of under 200km/hr during retrofit of old railroad line, as well as the prestressed reinforced concrete beam plate for railroad bridge of no more than 32m. The product is of single boom and simple-supported type, and it can achieve the full range transverse movement of the beam plate and lower it in place at one time. It features simple structure, light weight, safety and reliability, multifunction, high automation and convenient transport, etc.
