The driving wheel is electrically connected to the lithium battery 312 through a first wire, and the electromagnetic brake wheel is electrically connected to the lithium battery 312 through a second wire.

[0027] In order to facilitate the laying of the second electric wire, a wire groove 122 is opened at the top of the supporting leg 12. The wire groove 122 is arranged at the top of the supporting leg 12 along the length direction of the supporting leg 12. The second electric wire is laid in the wire groove 122, and the laying of the second electric wire is not affected by the installation of the supporting leg 12. At the same time, a cover plate 122a is provided on the top of the wire groove 122, and the cover plate 122a is detachably fixed to the wire groove 122 by bolts. The wire groove 122 can be sealed or opened by the cover plate 122a, which can facilitate the installation and maintenance of the second electric wire and protect the second electric wire at the same time.

[0028] In order to better support the forklift, two support legs 12 are provided. The two support legs 12 are symmetrically arranged on both sides of the front end of the chassis 11, and a second wheel body 121 is provided at the bottom of the front end of each support leg 12.
