鹅颈式低平板半挂车承载货物的主梁低于后轮,运载的货物重心低、稳定性和道路通过性好,适宜运输超高、超重的大型工程机械和矿山机械。1.结构组成鹅颈式低平板半挂车可以利用安装在车身上的升降缸,将半挂车车身前部支撑在地面上。待牵引车与半挂车的鞍座脱离后,牵引车驶离半挂车,如图1a所示。当牵引车驶离后,可通过升降缸将半挂车前部放在地面上。继续操纵升降缸,将鹅颈平台平放在地面上,可将鹅颈平台变换成半挂车爬梯,从而解决鹅颈式低平板半挂车后部大型工程机械和矿山机械装卸困难问题。如图1b所示。有些型号鹅颈式低平板半挂车车架后部设置液压马达驱动卷扬机,卷扬机
The gooseneck low-profile semi-trailer carries the main girder of the cargo below the rear wheels and lowers the center of gravity of the cargo carried. Its stability and roadability are good. It is suitable for large-scale construction machinery and mining machinery with super high and overweight. 1. Composition The gooseneck low-profile semitrailer can support the front of the semi-trailer body on the ground with a lift cylinder mounted on the bodywork. After the tractor and semitrailer saddle are disengaged, the tractor leaves the semitrailer, as shown in Figure 1a. When the tractor leaves, the front of the semi-trailer can be lowered to the ground via the lift cylinder. Continue to operate the lifting cylinder and lay the gooseneck platform flatly on the ground to transform the gooseneck platform into a semi-trailer ladder to solve the problems of large engineering machinery and mining machinery handling difficulties in the rear of the gooseneck low-plate semi-trailer. As shown in Figure 1b. Some models of gooseneck low-profile semi-trailer rear frame set hydraulic motor-driven winch, winch
