LDA Single beam Overhead Crane

 LDA model single girder overhead crane is designed as light type lifting equipment according to China standard. It is equipped with the features of reasonable structure, strong rigidity of whole set. The whole set is used with single lifting speed or double lifting speed electric hoist, its capacity can vary 1--20ton and span 7.5---31.5m, working class A3---A5 according to ISO standard, The standard working environment temperature is from -25 to 40°C. This kind of crane is widely used in factory, warehouse, stuff yard to lift goods, forbidden to use in flammable, explosive and corrosive environment(we have explosion proof and casting single girder crane for special condition). This single girder overhead crane is operated by cabin , pendant or remote control. Other requirements such as 35m span, high lifting height, variable speed can be achieved according to customer’s needs.
