Design and manufacture of steel structure shaft for sightseeing elevators. According to the dimensions of the civil engineering drawings for sightseeing elevators, the main beam of the steel structure for sightseeing elevators below 6 floors can be made of 150mm x 150mm x 0.5mm square steel, and the crossbeam can be made of 120mm x 80mm x 0.5mm square steel. Generally, external hanging sightseeing elevators are designed without a machine room. According to the national standard, the minimum height of the top floor without a machine room is 4.5 meters. It is best to use a light proof plastic aluminum plate for sealing on the top of the steel structure to protect the main engine. The pit of the sightseeing elevator should be 1.8 meters deep, and a crossbeam should be added between 2 meters of the steel structure height. The door opening should have a crossbeam height of 2.35 meters, and an additional crossbeam should be added on the decoration floor.
