Description

Technical Field

[0001] This utility model relates to the field of forklifts, specifically to an adjustable forklift arm for electric forklifts. Background Technology

[0002] Electric forklifts, as the name suggests, are forklifts driven by electricity. They can be used for stacking, handling, and storing goods and are widely used in warehousing and logistics, manufacturing, construction, and retail industries.

[0003] Currently, electric forklifts are mainly composed of a vehicle body, drive unit, and forklift arm. The forklift arm, also known as the fork or fork carriage, is the main load-bearing mechanism for goods. Under normal circumstances, the forklift arm has a lifting function. When in use, the forklift arm moves down to pick up the goods, and after the goods are picked up, it is lifted off the ground to facilitate the movement of the goods.

[0004] However, existing electric forklifts still have some problems. For example, when the forklift arm is picking up goods, it usually needs to be centered to ensure the stability of the goods during handling. However, in actual use, it is difficult to keep the forklift arm centered. Therefore, the goods may tilt or even tip over during handling and movement. This is especially true when there are potholes or other uneven surfaces on the moving path. This can not only damage the goods but also affect the normal handling and movement of the goods, thus posing certain shortcomings and hidden dangers. Utility Model Content
