[0002] In order to ensure the carrying capacity of the freight elevator, the applicant proposed a large-load freight elevator with patent number CN201911221555.8, which includes an 8:1 machine room layout structure. The 8:1 machine room layout structure includes a main load-bearing beam, a secondary load-bearing beam, a counterweight load-bearing beam, and two sets of car load-bearing beams. The main load-bearing beam, the secondary load-bearing beam and the two sets of car load-bearing beams constitute the installation frame structure of the machine room. The counterweight load-bearing beam and the two sets of car load-bearing beams form a three-column arrangement structure. A traction machine is installed on the main load-bearing beam, and the traction machine is arranged at one end close to the counterweight load-bearing beam. The secondary load-bearing beam and the two sets of car load-bearing beams are each provided with two car fixed rope pulleys, and the counterweight load-bearing beam is provided with three counterweight fixed rope pulleys. By rationally arranging the load-bearing frame and load-bearing in the elevator machine room, and combining the labor-saving principle of the car fixed rope pulley and the counterweight fixed rope pulley, the purpose of a small traction machine driving a large-load freight elevator is achieved by arranging a machine room structure with a traction ratio of 8:1, thereby reducing the production and manufacturing cost of the elevator machine room.
