井字架是我国建筑行业目前广泛使用的一种垂直运输设备。为了扩大井字架的使用范围,提高安全生产的可靠性,我公司在1988年研制了GSD60高层双篮独立式井架,见图1。其最大安装高度,独立式时为30.3m,附着式时为60.3m,吊臂最大起重量为1t,吊篮最大起重量,单篮为0.75t,双篮为1.5t,吊篮最大起升高度,独立式时为25.8m,附着式时为55.8m,
Tic Tac is a kind of vertical transport equipment widely used in the construction industry in China. In order to expand the scope of use of the derricks and improve the reliability of safe production, our company developed a GSD60 high-rise double-deck independent derrick in 1988, as shown in Figure 1. The maximum installation height is 30.3m in free standing mode, 60.3m in attached mode, the maximum lifting capacity of the boom is 1t, the maximum lifting capacity of the lifting basket is 0.75t for single basket, and 1.5t for double baskets. Height, 25.8m for free standing, 55.8m for attached type,
