The underground trash cans system features a steel pit, hydraulic lifting unit, and platform. Using the hydraulic scissor lift principle, the platform raises the container when waste needs to be collected, making disposal easy and efficient. When lowered, the bin remains concealed underground, effectively reducing odors, preventing insects, and keeping the environment clean. Widely used in residential neighborhoods, sidewalks, parks, plazas, and densely populated urban areas, this system provides a safe, hygienic, and space-saving waste management solution, making it particularly ideal for tourist cities and modern urban developments.
