The heavy-load freight elevator comprises a lift car, a bearing seat and a synchronizing shaft rotationally connected with the bearing seat are arranged at the top of the lift car, the synchronizing shaft extends to the two sides of the lift car, chain wheels are arranged at the two ends of the synchronizing shaft correspondingly, upper tensioning wheels are arranged above the chain wheels, and lower tensioning wheels are arranged above the chain wheels. A lower tensioning wheel is arranged below the chain wheel; an upper chain fixing device corresponding to the chain wheel is arranged at the top of the elevator shaft, a lower chain fixing device corresponding to the chain wheel is arranged at the bottom of the elevator shaft, a chain is arranged between the upper chain fixing device and the lower chain fixing device, and the chain is sequentially meshed with the upper tensioning wheel, the chain wheel and the lower tensioning wheel. Traction main machines are arranged on the two sides of the lift car correspondingly, and the traction main machines drive the lift car to reciprocate up and down along the chain. The double-motor driving and chain wheel and chain meshing structure improves the operation synchronism of the two sides of the lift car, the symmetrical structure on the two sides enables the lift car to operate more stably, and the load capacity of an elevator is improved.

    本发明公开了一种大载重的载货电梯,包括轿厢,所述轿厢的顶部设置有轴承座和与轴承座转动连接的同步轴,所述同步轴延伸至轿厢的两侧,所述同步轴的两端分别设置有链轮,所述链轮的上方设置有上张紧轮,所述链轮的下方设置有下张紧轮;电梯井道的顶部对应链轮设置有上链条固定装置,电梯井道的底部对应链轮设置有下链条固定装置,所述上链条固定装置和下链条固定装置之间设置有链条,所述链条依次与上张紧轮、链轮和下张紧轮啮合;所述轿厢的两侧分别设置有曳引主机,所述曳引主机驱动轿厢沿着链条上下往复运动。本发明双电机驱动、链轮链条啮合的结构提高了轿厢两侧运行的同步性,两侧对称的结构使轿厢运行更加平稳,提高了电梯的载重量。
