[0018] see figure 1 , figure 2 : The double-drive chain hoist has sequentially linked drives, transmission mechanisms, and reels. There are two sets of transmission mechanisms, one of which is a lifting transmission mechanism and the other a lowering transmission mechanism.
[0019] The output shaft 1 of the driver is provided with a spur gear 3, an inner gear 8 is provided on the edge of the spool 11, and a spur gear 9 is provided on the spool shaft.
[0020] The lift transmission mechanism adopts a spur gear transmission pair. The spur gear transmission pair has a coaxial input spur gear 2 and an output spur gear 10. The input spur gear 2 meshes with the drive output shaft spur gear 3, and the output spur gear 10 meshes with the inner gear of the drum. The ring 8 is engaged and the output spur gear 10 contains an overrunning clutch. An overrunning clutch may also be included in the input spur gear 2, and any one of the input spur gear 2 and the output spur gear 10 may inc...
