北京市第三建筑工程公司机械队设计试制了一辆安装、拆卸塔式起重机的支撑车,现已投入使用,从而改变了多年来2～6吨和3～8吨塔式起重机在安装或拆卸时使用大方木码垛、支搭承重架的笨重施工方法。过去在安装或拆除塔式起重机时,必须使用大量的枕木或大方木码成四方垛(见图1),在码垛时都是使用人力扛抬,一般需要17人左右,劳动强度很大。码垛时需要分段码高,同时还必须搭上坡道,工序繁杂,还容易发生安
Beijing No.3 Construction Engineering Company’s mechanical team designed a support vehicle for the installation and demolition of tower cranes, which has now been put into use, thereby changing the installation or disassembly of tower cranes of 2 to 6 tons and 3 to 8 tons over the years. A bulky construction method using generous wooden pallets and supporting load-bearing frames. In the past, when installing or dismantling tower cranes, a large number of sleepers or large wooden yards must be used to form a quadripartite (see Figure 1). In the stacking process, human labor is used to lift the tower cranes. Generally, about 17 people are needed and the labor intensity is high. When the palletizing requires a high yardage code, it must also be on the ramp, the process is complicated, and it is easy to happen.
