In order to reduce the equipment center of gravity, assembly unit is quick, described girder by about two main longitudinal griders form, be provided with middle joist between two main longitudinal griders, every main longitudinal grider independently saves beam separately by more piece to be formed, and connects with pin between the joint beam, the main longitudinal grider end face is the isoceles triangle shape, and described lifting overhead traveling crane has two.
Supporting leg is installed on the pulley of main longitudinal grider lower edge, the left and right sides and is equipped with drive motors in described, and drive motors all is arranged on the supporting leg crossbeam.
The length of described girder is 2.05~2.2 times of span of setting a roof beam in place, carriage and tail-bracket during the middle part of girder lower edge and rear end are provided with, and described accessory cart has two, in being installed in respectively on carriage and the tail-bracket.
Adopt technical scheme described in the utility model because the side of girder is a honeycomb structure, have light and amount of deflection little, the characteristics that rigidity is big.Main longitudinal grider independently saves beam separately by more piece to be formed, and connects with pin between the joint beam, and assembly unit is quick, and is solid and reliable.The main longitudinal grider end face adopts the isoceles triangle shape, and center of gravity is low, and via hole do not need to add counterweight, and is safe and reliable.
