双梁偏轨箱形门式起重机(即U型吊)具有许多优点,因此近来我国多数铁路货场迫切要求使用这种型式的起重机。根据部货运局的指示,我们设计了20/10吨双梁U型吊,并已由宝鸡桥梁厂和郑州装卸机械厂试生产。现仅以本起重机的使用范围、主要技术参数、构造特点、电气线路及操纵等简要介绍如下。一、使用范围 20/10吨双梁箱形门式起重机是具有偏轨箱形主梁、直腿、U型门架结构的龙门起重
Double-girder deviation rail gantry crane (that is, U-shaped crane) has many advantages, so most of our railway railroads urgently require the use of this type of crane recently. According to the instructions of the Ministry of Transportation, we designed 20/10-ton double-girder U-shaped cranes and have been trial-produced by Baoji Bridge Works and Zhengzhou Handling Machinery Works. Now only to the scope of use of the crane, the main technical parameters, structural features, electrical wiring and control briefly described below. First, the use of 20/20 tons of double-girder box gantry crane is a gimbaled box girder, straight leg, U-gantry structure gantry crane
