Description

Technical Field

[0001] The utility model relates to the technical field of fork frames, in particular to a forward-moving fork frame for a forklift. Background Art

[0002] A forklift refers to a variety of wheeled transport vehicles used for loading and unloading, stacking and short-distance transportation of palletized goods. The structural characteristics and working performance of the forklift are indicated by technical parameters such as rated lifting capacity, load center distance, and mast inclination angle. It is usually divided into types such as internal combustion forklifts and electric forklifts. The fork frame refers to a tool used for loading and unloading, stacking and short-distance transportation of palletized goods.

[0003] However, most existing forklifts rely on the forward and backward movement of vehicles, which makes it inconvenient for vehicles to enter and store pallets, such as deep inside a truck or in narrow storage aisles. As a result, workers need to manually transfer the pallets a second time, reducing work efficiency. Utility Model Content
