The invention relates to a suspender for a transversely reinforced aerial ladder truck, comprising a main suspender (11) which is rotatably arranged on a vehicle (10) and can extend in a multi-gear telescopic manner; the auxiliary suspenders (13) are combined to the two transverse side faces of the main suspender (11) in a multi-gear telescopic mode, and therefore the main suspender can be reinforced from the two sides through the auxiliary suspenders, and the overall flexural rigidity and the transverse bearing strength of the suspender are further improved. Furthermore, the device comprises an extension ladder which is assembled at the lower end of the main suspender in a manner of relatively moving along with the main suspender and extends to the ground when the aerial ladder truck runs so as to enable the trolley of the aerial ladder truck to descend to the ground, so that auxiliary suspenders for reinforcing are combined on the two side surfaces of the lower end of the main suspender, and the extension ladder is assembled at the lower end of the main suspender. An extension ladder capable of relatively moving and extending to the ground is combined, so that the trolley moving along with the boom by the extension ladder is lowered to a position close to the ground, and cargo loading and unloading of the trolley are easily realized.
本发明涉及一种用于横向加强式云梯车的吊杆,其包括:主吊杆(11),其可转动地设置在车辆(10)上,可多档伸缩延伸;以及辅吊杆(13),其分别可多档伸缩地结合到所述主吊杆(11)的横向两侧面,由此,可以通过辅吊杆从两侧方加强主吊杆,以进一步提高吊杆的整体抗弯刚度及横向承重强度。并且,包括:延伸梯,其可随所述主吊杆相对移动地装配在所述主吊杆的下端,在云梯车运行时延伸至地面,以使所述云梯车的台车下降至地面,由此,在两侧面结合有加强用辅吊杆的主吊杆的下端上面,可相对移动而延伸至地面地结合有延伸梯,从而使利用延伸梯随吊杆移动的台车下降至接近地面处,轻易地实现台车的货物装卸。
