上旋转桥式起重机的两种典型回转机构

Two Typical Rotating Mechanism of Upper Rotating Bridge Crane

简要介绍了旋转桥式起重机,提出了上旋转桥式起重机的两种典型回转机构,即环轨式回转机构和回转支承式回转机构,并对这两种机构进行了详细介绍和对比。

This paper briefly introduces the rotary bridge crane,and puts forward two typical rotary mechanisms of the upper rotary bridge crane,i.e.the ring rail rotary mechanism and the rotary supporting rotary mechanism.The two mechanisms are introduced and compared in detail.
