The 4 to 1 suspension elevator is mainly suitable for elevators with large load and low speed.

At present, the 4:1 elevator has a complex structure, which makes the elevator occupy a large area in the hoistway, and the load-bearing effect is poor. In addition, permanent magnet synchronous traction machines are widely used in existing 4:1 elevators, and most of the traction devices adopt side counterweight structures, and the elevator shaft layout is also designed accordingly. However, the conventional design of the existing traction and load-bearing structures results in a low utilization rate of the plane of the elevator shaft, especially in the depth direction. Because the conventional 4:1 side counterweight traction structure will occupy a lot of depth space in the elevator shaft, and The auxiliary beam also needs to be inserted into the wall, so it cannot meet the construction requirements of some special machine rooms. Therefore, the existing 4:1 elevator structure requires the main and auxiliary beams to be inserted into the wall at the same time, which not only causes high civil construction costs, but also wastes materials for the auxiliary beams.
