The existing ladder cannot be adjusted in height according to the height and width of the dry cooler installation foundation, which makes it inconvenient to use during assembly, installation, maintenance and repair.
A folding ladder with adjustable height from the ground was designed. The upper ladder section is connected by mounting holes and hinges, while the lower ladder section can be detached and installed via hinges. The upper handrail is equipped with buckles and stops to achieve the adjustment of the ladder's height and angle, ensuring safety and stability.
The ladder height and angle are flexibly adjustable to meet the needs of different scenarios, improve the convenience and safety of transportation and use, and ensure the stability and safety of climbing up and down the ladder on the dry cooler.
