The invention discloses a machine-room-less elevator with a traction ratio of 4: 1. A diversion sheave beam stretches across a front-side well wall and a rear-side well wall and is arranged on one side of the top of a well, and a traction machine base is arranged on the other side, opposite to the diversion sheave beam, of the top of the well; two counterweight side movable pulleys are arranged at the top of the counterweight, a preset angle is formed between the axes of the two counterweight side movable pulleys and the central plane of the counterweight guide rail, and the preset angle is not zero; the traction machine, the counterweight side fixed pulley, the lift car side rope head assembly and the counterweight side rope head assembly are all fixed to the upper portion of the traction machine base, and the center of the counterweight side fixed pulley coincides with the center of the counterweight. The two lift car side top diversion sheaves are fixed to the upper portion of the diversion sheave beam and distributed on the two sides of the center line of the lift car guide rail. Two pairs of car bottom diversion sheaves are arranged at the bottom of the car and distributed on the two sides of the center line of the car guide rail. The counterweight guide rails are arranged on the different sides of the lift car guide rails, and the center lines of the counterweight guide rails are perpendicular to the center line of the lift car guide rails.

    本发明公开了一种曳引比4比1的无机房电梯,反绳轮梁横跨前后侧井道壁设置在井道顶部一侧,曳引机座设置在井道顶部与反绳轮梁相对的另一侧;对重顶部具有两个对重侧动滑轮,所述两个对重侧动滑轮的轴线与对重导轨中心面呈预设角度,所述预设角度不为零;曳引机、对重侧定滑轮、轿厢侧绳头组件和对重侧绳头组件都固定在曳引机座上部,对重侧定滑轮中心与对重中心重合;轿厢侧顶部反绳轮为两个,固定在反绳轮梁上部,分布在轿厢导轨中心线的两侧;轿厢底部具有两对轿底反绳轮,分布在轿厢导轨中心线的两侧;对重导轨设置在轿厢导轨的异侧,对重导轨中心线与轿厢导轨中心线相垂直。
