摘要： A support frame system of a elevator cage includes a first support frame and a secondary support frame outside the cage. The first support frame is composed of two first columns respectively positioned at the left side and the right side of the cage, a first upper beam and a first lower beam respectively positioned on the top of the cage and under the cage. The secondary support frame includes a secondary upper beam parallel to the first upper beam, and its two ends are fixed to the first upper beam. Two return pulleys are installed between the first upper beam and the secondary upper beam. Because there is some distance between two return pulleys and the upper beams, the two return pulleys may be kept away from the guide shoe and be provided at the edge of the cage. According to the present invention, the system has the following advantages. Because two return pulleys are installed between the first upper beam and the secondary upper beam and are kept away from the guide shoe, the system achieves that the traction machine is installed outside the vertical projection of the maintenance space on the top of the cage. In other words, the traction machine can be installed to keep away from the maintenance space on the top of the cage. At the same time, the guide rail can be kept away from the first columns and close to the cage wall, so as to reduce the space needed when the elevator runs.

摘要： A traction driving elevator system includes a first guide rail and a secondary guide rail installed on the shaft, a cage moved along the first guide rail and a counterweight moved along the secondary guide rail, and a traction machine. The traction machine further includes a stator, a rotor and a traction sheave installed inside the machine housing. The two ends of the machine housing are fixed on the tops of two opposite shaft walls. The cage and counterweight are suspended on the traction sheave of the traction machine by a set of steel ropes. According to the present invention, the system has the following advantages. Because the stator, the rotor and the traction sheave of the traction machine are installed inside the machine housing which is served as a bearing beam, nothing but the machine housing occupies a height of the upright space of the shaft and the traction machine do not additionally occupy the upright space of the shaft.. Therefore, the system effectively reduces an occupancy rate of the vertical space of the shaft, proportionally increases an utilization rate of the vertical space of the shaft, reduces the height needed by the top layer of the building and the cost of raw and processed material.
