A little about this puzzle

Inside a safety training hall, an artificial cave entrance forms a ground-level demonstration model. A mecha steadies one four-column portal frame with both grippers, its four feet aligned with four anchored sockets. A material rack holds the buffer pad, arch block, and crossbeam sleeve. The instructor controls the mecha in a safety vest while a student watches behind the rail, holding a clipboard with one broad metal clip at the top. Bold adventure-comic contours and engineering-yellow surfaces separate the platform, frame, and material rack. The scene presents a teaching model; the cave facade does not carry a real mountain.
