神钢7250起重机是由日本神户制钢所制造的全液压履带式起重机,最大起重量250 t,有大小起重臂20节,总长约159 m。通过各种组装,可组合成不同长度的起重臂,也可组装成塔式起重机状态,以达到不同的起吊目的。由于起重臂数量多,在拆装和运输过程中较易产生起重臂被撞坏等情况,须及时修理。为方便同行修理,现介绍以下内容。1.起重臂的材料及采用的焊条起重臂为由特殊合金钢钢管制成的桁架式结构,见
The Kobelco 7250 crane is a fully hydraulic crawler crane manufactured by Japan’s Kobe Steel with a maximum capacity of 250 t and a jib with a size of 20 knots and a total length of approximately 159 m. Through a variety of assembly, can be combined into different lengths of the boom, can also be assembled into a tower crane state, in order to achieve different lifting purposes. Due to the large number of jibs, jib cranes are more likely to be damaged during dismantling and transportation, and the jibs must be promptly repaired. To facilitate peer repair, are introduced below. 1. The material of the jib and the use of the jib boom are made of special alloy steel pipe truss-type structure, see
