The invention discloses a freight elevator driven by double traction wheels. The freight elevator driven by the double traction wheels comprises a lift car device, a counterweight device and a traction system with a traction machine, the traction machine comprises a traction motor and two traction wheels synchronously driven and controlled by the traction motor, the traction system further comprises two groups of traction ropes, two groups of lift car rope returning wheels are correspondingly fixed on the upper portion of the lift car device, two groups of counterweight rope returning wheels are arranged at the upper part of the counterweight device, after each group of traction ropes correspondingly wind around the corresponding traction wheel, and the two end parts of each group of traction ropes correspondingly wind around the corresponding lift car rope returning wheel and the corresponding counterweight rope returning wheel and then are correspondingly and fixedly connected with arope head frame at the top of a hoistway. According to the freight elevator driven by the double traction wheels, two groups of symmetrical traction systems are achieved through the two traction wheels, the traction force is increased, and the freight elevator is suitable for large-tonnage elevators; and the lift car device can correspond to the upper and lower center lines of the counterweight device conveniently, and the space arrangement is more reasonable.

    一种双曳引轮驱动载货电梯,包括轿厢装置、对重装置、具有曳引机的曳引系统,所述曳引机包括曳引电机、受所述曳引电机同步驱动控制的两个曳引轮,所述曳引系统还包括两组曳引绳,所述轿厢装置上部分别固定有两组轿厢返绳轮,所述对重装置上部设置有两组对重返绳轮,每组所述曳引绳分别绕过相应的所述曳引轮后,其两端部分别绕过相应的所述轿厢返绳轮与相应的所述对重返绳轮后分别与井道顶部的绳头架固定连接。本发明提供一种双曳引轮驱动载货电梯,两个曳引轮,实现两套对称的曳引系统,曳引力增大,适合大吨位电梯;方便实现轿厢装置与对重装置的上下中心线相对应,空间安排更合理。
