The invention discloses a standby folding ladder assembly and a using method thereof, a crawler chassis and engineering machinery. The standby folding ladder assembly comprises a folding ladder, an embedded tool box, a sealing plate assembly and a sliding component. The folding ladder has a folding function and is fixed on a longitudinal beam outer side plate after being unfolded to assist a driver in getting on and off the vehicle; the embedded toolbox is arranged in the longitudinal beam, an opening communicated with a cavity of the toolbox is formed in a longitudinal beam outer side plate serving as a toolbox coaming, and the opening is used as an inlet and outlet for the folding ladder to go in and out of the toolbox; the sealing plate assembly is installed at the opening and used for covering the opening and protecting the folding ladder arranged in the tool box. The sliding component is installed in the tool box, and the folding ladder is assembled on the sliding component and used for pulling the folding ladder out of the tool box or pushing the folding ladder into the tool box. When the electric folding ladder cannot be normally used, temporary standby treatment can be rapidly achieved, and it is guaranteed that equipment cannot be shut down for a long time due to faults of the electric folding ladder.

    本发明公开了一种备用折叠梯总成及其使用方法、履带底盘、工程机械,包括折叠梯、内嵌式工具箱、封板组件和滑移部件;折叠梯具备折叠功能,展开后固定在纵梁外侧板上,辅助驾驶人员上下车;内嵌式工具箱置于纵梁内部,用作工具箱围板的纵梁外侧板上设有与工具箱的腔体相连通的开口,所述开口用作折叠梯出入工具箱的进出口;封板组件安装在所述开口处,用于覆盖住开口,对内置在工具箱中的折叠梯进行防护;滑移部件安装在所述工具箱中,所述折叠梯装配在滑移部件上,用于将折叠梯从工具箱中拉出或者将折叠梯推入到工具箱中。本发明在电动折叠梯无法正常使用时,可快速实现临时备用处理,保证设备不因电动折叠梯故障造成长时间停机。
