近年来,由于小车变幅长臂架结构计算方法的发展,“等强度、变截面”长臂架的出现,使长臂架的结构设计更合理,致使附着式小车变幅长臂架塔机愈来愈被人们重视,在建筑施工中的应用日益广泛。一、附着式小车变幅长臂架塔机的优点在建筑施工中,根据不同工程的施工需要,除对塔机的起重量和高度有一定的要求外,其水平施工面(即塔机臂架的回转半径)也是一个十分重要的性能参数。附着式小车变幅长臂架塔机可随着建筑物的不断提高而附着升高,因此在高度上容
In recent years, due to the development of the calculation method for the luffing long boom structure of the trolley, the emergence of the “equivalent strength, variable cross section” long boom allows the structural design of the long boom to be more reasonable, resulting in the attachment of the trolley luffing tower crane. More and more people are paying attention to it, and its application in building construction is increasingly widespread. 1.Advantages of Adhesive Trolley Luffing Long-arm Tower Cranes In the construction of buildings, according to the construction requirements of different projects, in addition to certain requirements for the crane’s capacity and height, the horizontal construction surface (ie tower crane arm) The radius of gyration of the frame is also a very important performance parameter. Attachment trolley luffing long boom tower crane can be attached to the building as the building continues to increase, so in height
