The invention relates to a cargo boom base of a light-weight hoisting transport vehicle. The cargo boom base comprises a base disc (1), a left side plate (2), a right side plate (3), a front connecting plate (4), a rear connecting plate (5) and a variable-amplitude oil cylinder hinge seat (6), wherein a winch mounting plate (7) is arranged between the left side plate (2) and the right side plate (3), the two sides of the winch mounting plate (7) are welded on the rear sides of the left side plate (2) and the right side plate (3), the left side plate (2) and the right side plate (3) are each composed of an inner side plate (8) and an outer side plate (9), the peripheries of the outer side plates (9) are bent towards the inner side plates (8), the edge parts are welded with the peripheries of the inner side plates (8), and the lower parts of the inner side plates (8) and the outer side plates (9) are welded with the base disc (1). The cargo boom base has the advantages that the strengthis guaranteed, the weight is light, the open welding phenomenon is not likely to happen, and safety is good; and due to the fact that welding stress is overcome, the open welding phenomenon is avoided, the lifting capacity can be improved, and use is safer and more reliable.
本发明涉及一种轻型起重运输车起重臂底座,它包括底座圆盘(1)、左侧板(2)、右侧板(3)、前连接板(4)、后连接板(5)和变幅油缸铰接座(6),左侧板(2)和右侧板(3)之间设有两侧分别焊接在左侧板(2)和右侧板(3)后边上的卷扬机安装板(7),左侧板(2)和右侧板(3)分别由内侧板(8)和外侧板(9)构成,外侧板(9)的周边向内侧板(8)的方向弯折,边部与内侧板(8)的周边焊接在一起,内侧板(8)和外侧板(9)的下部分别与底座圆盘(1)相焊接连接。它具有强度有保证,重量轻,不容易出现开焊现象,安全性好的优点。由于克服了焊接应力,避免了开焊现象,可以提高起重能力,使用起来更加安全可靠。
