Beam launcher is a special heavy equipment used to erect precast concrete beams on bridge piers during the construction of highway and railway bridges. The beam launcher is mainly composed of the main beam, front, middle and rear outriggers, auxiliary brackets, upper beams, cranes, traverse rails, hydraulic machine electrical systems, etc.
Henan Dafang Heavy Machine CO.,LTD developed a new type of beam launcher after improving the original beam launcher. The beam launcher has a lightweight structure, uses counterweights to balance to through holes, and walks forward, so there is no need to lay tracks on the beam surface. It can erect straight, curved, and longitudinally equal-span and variable-span double-line prestressed concrete whole-hole box girder. It has the characteristics of good beam hoisting stability, high working efficiency, safety and reliability, convenient variable span adjustment, and convenient operation.
