The invention relates to the technical field of semitrailer crawling ladders, in particular to a semitrailer crawling ladder capable of transversely moving. The crawling ladder comprises a main crawling ladder and a cross beam, an oil cylinder base is welded to the middle of the cross beam. Telescopic oil cylinders are symmetrically arranged on the two sides of the oil cylinder base; sliding grooves are symmetrically formed in the two sides of the cross beam. Sliding brackets are arranged in the sliding grooves in a sliding fit mode, the main crawling ladder is rotationally arranged on the lower portions of the sliding brackets through first rotating shafts, hexagon bolts are fixedly installed at the two ends of the first rotating shaft, hexagon nuts are screwed at one ends of the hexagonbolts, and the auxiliary crawling ladder is rotationally arranged on the lower portion of the main crawling ladder through a second rotating shaft. According to the semitrailer crawling ladder capableof transversely moving, the semitrailer crawling ladder capable of moving transversely can achieve multiple purposes, therefore, the situation that the weight of a semitrailer is increased due to thefact that an overwide crawling ladder is used is reduced, and the semitrailer crawling ladder is better suitable for being used by semitrailers on the market.

    本发明涉及半挂车爬梯技术领域,尤其涉及一种可横向移动的半挂车爬梯,包括主爬梯和横梁,所述横梁的中部焊接有油缸底座,且油缸底座的两侧对称设有伸缩油缸,横梁的两侧对称开设有滑槽,滑槽内均滑动配合有滑动托架,滑动托架的下部通过第一旋转轴转动设置有主爬梯,且第一旋转轴的两端安装固定有六角螺栓,六角螺栓的一端螺合有六角螺母,主爬梯的下部通过第二旋转轴转动设置有副爬梯。本发明中,此可横向移动的半挂车爬梯可以做到一车多用,从而减少使用过宽的爬梯对半挂车辆重量的提高,更好的适用于市场上的半挂车进行使用。
