Installation of steel and steel concrete bridge structures using longitudinal launching

Used in the construction of bridge structures across rivers or at the conjected conditions of site

Bridge structures are assembled on site, located at places suitable for construction

Installation speed reaches 1500 t of the steel structures per month

Equipment:

Pushing devices of various design, including jacks with the piston stroke of 2.0 m and lifting capacity of 1000 t
Balancing devices with antifriction cover for the launching of structure (polymer materials with a friction ratio of 2% - 4%)
Launching noses, receiving consoles, bend pulling devices
Jacks for the installation of the bridge structure on the supports
Lifting and welding equipment for structural assembly at launching slipway
