Abstract
YJ200-serial hydraulic loading and unloading machine solves the problem that the existing loading and un-loading machine fails to load or unload pre-fabricated beam in different spans and large sizes.The main structural compo-nents include the gantry frame,lifting beam,and traveling mechanism.And the column is equipped with a lifting hydraulic cylinder driving the lift beam to move up and down,the piston rod of the lifting cylinder is connected to the lifting beam, the column is fixed to the ground beam in the lower part,and the travelling mechanism is connected to the ground beam.关键词
