Development of MGHZ1200 beam lifter

900T Pneumatic Girder Gantry Cranes and 900T Transportation Girder Vehicles, 900T Span Carriers are designed for high speed rail projects.

Technical description of in-service beam-hoisting cranes used in passenger railway line construction;

By using the theory of shell finite element and taking the influences of integral distortion and local stress effect,this paper constructs the model of finite element for upgrade ring beam;and adopting the finite element software of ANSYS,makes the nonlinear analysis on upgrade ring beam in the engineering,which provides an important foundation for the design and construction of the engineering.
