Behind the pit, a green bucket elevator is vertically installed, its bottom buried in the pit and its top passing through a two-layer steel frame. The drive motor is located at the top and connected to a red pulley. An inspection window is installed on the side of the elevator. To the right of the elevator, a belt conveyor extends laterally, with black sidewalls on the conveyor belt and black rollers with red end caps. The internal structure of the factory is visible, with clear equipment placement and open areas on the ground. On the left side of the image, there is a blue low-voltage distribution cabinet with a black frame and fixing devices inside the door. Several yellow protective panels are placed on the ground in front of the cabinet.
