敞車車墙变形整修器有两种:一种是整修側墙用,一种是整修端墙用。两者都是用一辆带轉动臂的专用車(图1)将整修器吊在待修敞車的整修位置。在該車上装有一部液压装置,供应整修器上液压缸內所需要的液压力。端墙整修器的液压缸的能力为45.5吨,活塞行程为394毫米。使用时,此車将整修器吊在相互联挂的两辆端墙之間,以整修端墙的鼓起部分。 There are two types of gondola car wall truss remodelers: one for side wall repair and one for trim end wall. Both use a dedicated arm with a swing arm (Figure 1) to hang the trimmer on the gondola for repair. The car is equipped with a hydraulic device that supplies the required hydraulic pressure in the hydraulic cylinder of the finisher. Endwall trimmers have a hydraulic cylinder capacity of 45.5 tons and a piston stroke of 394 mm. When in use, the car hangs the trimmer between the two end walls connected to each other to refit the bulge of the end wall.
