[0033] Furthermore, by collectively arranging the permanent magnet synchronous traction machine 20, the guide wheel 40 and the two rope breaking protection devices 50 on the machine base 10, the space utilization rate can be improved and the installation is convenient for operators;

[0034] In addition, the broken rope protection device 50 can realize safety control, which has strong practicality.

[0035] Example 2

[0036] Based on Example 1 and with reference to Figure 1 As shown, the base 10 of the present application includes two first angle steel sheets 11 arranged side by side along a first direction and two second angle steel sheets 12 arranged side by side on the two first angle steel sheets 11 along a second direction, and the traction wheel 30 is fixed above the two second angle steel sheets 12 through the first frame 60, the permanent magnet synchronous traction machine 20 is arranged on the outside of one side of the first frame 60 and its output end is connected to the traction wheel 30, and the guide wheel 40 is fixed above the two second angle steel sheets 12 through the second frame 70.

[0037] In order to ensure the stability of the first frame 60 and the second frame 70 , the present application connects two stabilizing beams 100 between the first frame 60 and the second frame 70 .
