How does the agricultural machinery assembly line work?

What does the production line look like? This picture shows a typical tractor or harvester assembly line. The factory building is very high, with a ground conveyor line in the middle, working stations on both sides, and a platform above it. This design is very practical-the upper layer is used for parts and pre-assembly, and the lower layer is concentrated on assembling the whole machine without interfering with each other. The red track above the head is a crane, specially used for lifting heavy objects. The engine and gearbox on the agricultural machinery weigh hundreds of kilograms each and cannot be moved without a crane. Workers wear yellow helmets, use remote control to control the hook, accurately place large parts on the frame, and then tighten them with hand tools. The ground is conveyed by wide plate chains or roller beds, not by thin conveyor belts. Because the agricultural machinery chassis is large and the wheel spacing is different, ordinary conveyor belts cannot be used. This kind of ground line can be stopped, speed can be adjusted, and different models...
