Beschreibung
Zusammenfassung:	The invention provides a quick-start slow-stop double-layer lifting and variable-power protection aerial work platform, which belongs to the technical field of aerial work platforms, and mainly comprises a platform walking device, a quick-start slow-stop device consisting of a spring, a push plate and a roller, and a first-layer lifting device consisting of a shear fork group A, a hydraulic rod A and a platform A, the two-layer lifting device is composed of a shear fork set B, a hydraulic cylinder B and a platform B, and the variable power protection device is composed of a tool box, a seat, a soft cushion A and a soft cushion B. The double-layer lifting platform is characterized in that the double-layer lifting platform can be quickly started and slowly stopped and can be changed into multifunctional protection. Walking of the aerial work platform is achieved through the platform walking device, quick-start lifting and buffering stopping of the aerial work platform are achieved through the quick-start and sl
