Description

The JQ 900 Series Bridge Girder Erection Machine is an advanced piece of equipment designed specifically for the construction of passenger dedicated lines (PDL) and high-speed railways. This robust machine is engineered to handle the erecting of 900 tons of precast concrete box girders with a single span, making it an essential tool for modern railway construction projects.

Featuring a gantry structure with double girders and three legs, this equipment is capable of crossing a simply supported beam during construction. Its innovative design allows for a girder carrier to quickly depart after feeding the girder from the tail end, enhancing operational efficiency.

The machine utilizes a close hydraulic transmission system along with hydraulic suspension support for its walking system, ensuring an even load distribution across each tire set. The inclusion of a middle leg and a back leg facilitates smooth longitudinal movement and easy transference between different bridge locations, providing unparalleled convenience and flexibility in various construction scenarios.
