This instruction is mainly to design the roof bean part, including running mechanism of the cart, the design of bridge shelf and each part of the inside parts accessory, assembly store and welding structure. During the course of designing ,consult some relevant materials: the cart adopts different drive scheme ,the end roof beam adopts case shape structure welding by stencil plates ,the connecting end installation of roof beam sets up in the end middle part of the roof beam ,connected by high strength bolted joint through the connecting plate and angle steel .The design of beam bridge shelf mainly refers to weld structure and craft ,and this requires to know something about weld sufficiently and apply the knowledge studied flexibly and correctly .
