应用于河网地区重型钢管构件装卸的新型桅杆式组合抱杆的设计

Design of new mast type combined gin-pole for loading and unloading heavy duty tubular steel component in river network area

针对1 000 kV皖电东送淮上线工程钢管塔河网地区运输时,吊车无法进场且从运输船舶上装卸塔材无可用起重设备,研制了组合抱杆起重系统。该系统可有效解决从船舶上将重型钢管构件吊装至岸上的难题。

Because cranes can not enter into the river network area where tubular steel tower of Huainan-Shanghai 1 000 k~ UH~ grid engineering of transmiting electricity from Anhui to East China and it is impossible to find hoisting equipment for loading and unloading heavy duty tubular steel component in transport ship, combined gin-pole hoisting system was designed to solve the difficulties for un- loading heavy duty tubular steel tower from ship to bank area.
