30吨多能塔式起重机是利用国产2—6吨塔式起重机改装而成的。原机最大起重量只有6吨,不能满足单层工业厂房的结构吊装。在原机上加装2根把杆,把原机的起重量提高5倍多,扩大了原机的使用范围。这种改装既不破坏原机的结构,又集中了塔式,桅式及桩架起重机的优点,使用灵活方便,只要在厂房跨中铺设一条行走轨道就能完成30
The 30-ton multi-energy tower crane is made by using a domestically produced 2-6-ton tower crane. The maximum lifting capacity of the original machine is only 6 tons and it cannot meet the structural lifting of single-layer industrial plants. Two additional levers were added to the original machine to increase the lifting capacity of the original machine by more than five times, which expanded the scope of use of the original machine. This kind of modification neither destroys the structure of the original machine, but also concentrates the advantages of the tower type, the truss type and the pile crane, and is flexible and convenient to use. As long as a walking track is laid across the plant, it can be completed.
