For the construction of teaching equipment in school physics, chemistry, and biology laboratories, the laboratory hoisting system adopts a fully concealed design with a hatch-style door. When the door is closed, it blends seamlessly with the cabin, creating a sleek and aesthetic overall appearance. When opened, it achieves smooth folding and storage through multi-motor linkage control, completely concealing it on the side of the cabin, ensuring 360掳 unobstructed view, balancing practicality and aesthetics.
