Provided are a high-altitude greening lifting device and system, which relate to the technical field of vertical greening. The high-altitude greening lifting device comprises a flexible hoisting belt, fixing assemblies, an anti-deviation rope, and flowerpots, wherein the flexible hoisting belt clamps several flowerpots in a lengthwise direction through the fixing assemblies respectively; the anti-deviation rope is successively connected, in the lengthwise direction of the flexible hoisting belt, to the several fixing assemblies; and the fixing assemblies are detachable. Through the high-altitude greening lifting device provided in the present invention, installation of a large-area support is avoided by means of the design combining the flexible hoisting belt and the flowerpots; the design of the anti-deviation rope avoids safety accidents caused by drifting of the flowerpots with wind during a lifting process, and improves the typhoon resistance capability; and the fixing assemblies are detachable, which facilitates spacing adjustment of the flowerpots according to user requirements or seasonal changes, thus meeting usage requirements of users. A high-altitude greening lifting system which uses the high-altitude greening lifting device is additionally provided in the present invention, and the stability of the entire system is improved by means of installing an upper support and a lower support.L'invention concerne un dispositif et un système de levage de végétalisation à haute altitude, qui se rapportent au domaine technique de la végétalisation verticale.
