Description

Technical Field

[0001] The utility model relates to the technical field of forklifts, in particular to a lithium-ion forklift with a load-bearing plate capable of being extended laterally for use. Background Art

[0002] A forklift is an industrial vehicle used for transporting and stacking items. Forklifts include manual forklifts, which are typically operated manually and powered by electricity. Manual forklifts use forks to move goods to the desired location. Forklifts are widely used in warehousing, manufacturing, transportation, construction, and other fields.

[0003] Most lithium-ion forklifts use two sets of horizontal load plates to transport items. The load plates of existing lithium-ion forklifts are usually fixed in position, and cannot pass through narrow aisles. When encountering items with large bottom surfaces, they have poor stability and cannot be transported. Most of them cannot be extended horizontally. In addition, the load plates of existing lithium-ion forklifts usually have no obstructions. When encountering some soft-packaged items, they are prone to shaking and tipping, causing the items to fall, and most of them cannot prevent tipping. Utility Model Content
