[0002] Small-tonnage forklifts are small loading and unloading vehicles, usually forklifts with a rated load capacity of 5 tons or less, mainly used for the handling and stacking of light goods. Due to their lightness and flexibility, they are widely used in light industries, supermarkets, stations, retail stores, gas stations, factory workshops, warehouses, circulation centers and distribution centers, etc. Small-tonnage forklifts can enter the narrow passages of warehouses or small workshops to load, unload, carry and stack goods. Compared with large forklifts, they have lower initial investment and maintenance costs and are easy to learn and use.

[0003] As the only part of the vehicle that contacts the ground, the tire can support the vehicle body, alleviate external impact, achieve contact with the road surface and ensure the vehicle's driving performance. In the process of assembling tires on a traditional vehicle assembly line, it is necessary to manually lift the tires onto a mobile trolley platform and then transport the tires to the assembly line. In order to align the installation position of the tire rim and the axle hub, two people are required to place the tire vertically and rotate it to the appropriate position for assembly, which cannot meet the line rhythm. This process is difficult to manually carry tires, requires a large amount of human resources, and tires are prone to falling when moving and rotating them, posing a huge safety hazard.

The lower limit plates 302 are relatively arranged at both ends of the base 301, and the upper limit plate is relatively arranged at the middle part of the bottom of the slide plate 201. During the sliding process of the slide plate 201, the lower limit plate 302 and the upper limit plate on the same side contact to limit the slide plate 201 from leaving the slide rail 304.

[0026] Example 2 Based on the first embodiment, this embodiment provides a method for using a tire assembly device for a small tonnage forklift. Specifically, it includes: Step 1: Remove the pin 105 on the top of the tray 101 , and place the tire vertically on the top of the tray 101 , with the tire surface in contact with the unpowered roller 103 .

[0027] Step 2: Release the brake 205, drive the tray 101 to move horizontally to the center of the tire rim through the slide plate 201, and lock the brake 205 to prevent deviation during the assembly process.

[0028] Step 3: The tire is driven to rotate by the unpowered roller 103 until the tire rim is aligned with the bolt mounting hole of the axle wheel hub, and the tire installation is started. During the tire installation process, the tray 101 is rotated to adjust the installation angle to achieve fine adjustment of the tire horizontal installation angle.

[0029] Step 4: After the installation is completed, release the brake 205, return the tray assembly 1 to its original position, install the pin 105 on the top of the tray 101, and lock the brake 205.
