Thus, with this configuration, multi-speed transmission 10 has the following operating conditions: heavy load working condition, first light load working condition, second light load working condition and neutral working condition.
When multi-speed transmission 10 is operating in a heavy duty condition, second clutch 52 is closed, first clutch 51 and third clutch 53 are disengaged, first gear 31 is an input, and first gear 31 may be driven by a power source, such as an electric motor (not shown); the first shaft 21 and the second shaft 22 are output.

When the multi-speed transmission 10 is operating in the first light load condition, the first clutch 51 is closed, the second clutch 52 and the third clutch 53 are released, the first gear shaft 31 is input, and the first shaft 21 and the second shaft 22 are output.

When the multi-speed transmission 10 is operating in an idle condition, the first, second, and third clutches 51, 52, 53 are disengaged, the first and second shafts 21, 22 are input, the first, second, fifth, sixth, and thirteenth gears 31, 41, 42, 45, 46, 413 remain stationary, and the remaining gears, shafts, and shafts are idle. Under no-load conditions, multi-speed transmission 10 may be serviced.
Where "heavy load" is a large load experienced by multi-speed transmission 10 as compared to "light load". Under light load conditions and under heavy load conditions, multi-speed transmission 10 has different output rotations under the same input rotation. Meanwhile, the outputs of the first shaft 21 and the second shaft 22 are turned the same. In addition, the different output steering of the light load and the load is realized by adopting the gear pairing of different stages of the light load and the heavy load. Under heavy load conditions, the output rotation speeds of the first shaft 21 and the second shaft 22 are low, and under light load conditions, the output rotation speeds of the first shaft 21 and the second shaft 22 are high.
In summary, the present invention provides a novel multi-speed transmission architecture that allows for three-speed output and neutral functionality with a parallel shaft transmission arrangement, and that can accommodate more operating conditions for ease of control, using the multi-speed transmission 10 described above. The gear shifting function realized by the clutch has stable and reliable performance, and can meet the working condition requirements of continuous work and frequent gear shifting. And the three clutches that perform the shifting function are located external to multi-speed transmission 10, with ease of replacement when the clutch plates are worn. Meanwhile, the three clutches are located on the same side outside the case 11, and the entire multi-speed transmission 10 is simple and compact in structure and convenient to assemble.
The present invention also provides a lifting apparatus comprising a multi-speed transmission 10 as described in any of the embodiments above. The specific type of hoisting device is not limited, and in this embodiment, for example, the hoisting device is a crane, and drums (not shown) are provided on the first shaft 21 and the second shaft 22 of the multi-speed transmission 10, and the drums are connected to the spreader by wire ropes. In other embodiments, a spool may be provided on the first shaft 21 or the second shaft 22, the spool being connected to the spreader by a wire rope. The output of the first shaft 21 can control the rotation of the winding drum arranged on the first shaft 21 to control the lifting and the lowering of the lifting appliance, the output of the second shaft 22 can control the rotation of the winding drum arranged on the second shaft 22 to control the lifting and the lowering of the lifting appliance, the output of the first shaft 21 and the output of the second shaft 22 are identical in steering, and the winding drums respectively arranged on the first shaft 21 and the second shaft 22 can be enabled to rotate stably so as to be beneficial to the stable lifting and the lowering of the lifting appliance.
Meanwhile, the output rotation speed of the first shaft 21 and the second shaft 22 of the multi-speed transmission 10 is low under the heavy load working condition, and the output rotation speed of the first shaft 21 and the second shaft 22 is high under the light load working condition, so that stable lifting and descending of the lifting appliance are facilitated.
Further, multi-speed transmission 10 has different output rotations under the same input rotation under light-load conditions and heavy-load conditions. For example, under heavy load conditions, multi-speed transmission 10 has a positive output steering to raise the spreader; under light load conditions, the multi-speed transmission 10 has a reverse output steering to lower the spreader. Thus, the multi-speed transmission 10 of the present invention may be used to accommodate different operating condition demands of a crane.
In summary, the above embodiments are provided to illustrate the principles of the present invention and its efficacy, but not to limit the invention. Modifications and variations may be made to the above-described embodiments by those skilled in the art without departing from the spirit and scope of the invention. Accordingly, it is intended that all equivalent modifications and variations of the invention be covered by the claims, which are within the ordinary skill of the art, be within the spirit and scope of the present disclosure.
