Description

Technical Field

[0001] The invention relates to the technical field of lifting mechanisms, in particular to a fast and safe lifting mechanism for a four-way vehicle. Background Art

[0002] The jacking mechanism is a mechanism for increasing or decreasing standard sections. In the jacking mechanism used for four-way vehicles, this structure is used to complete the actions of picking up and preventing goods. In the picking link, the four-way vehicle enters under the pallet, aligns with the position where goods need to be picked up, and then starts the lifting mechanism. The lifting mechanism lifts the tray so that the bottom of the pallet leaves the L-beam of the shelf or the surface of the conveyor chain to complete the pallet's detachment from the shelf and achieve the purpose of picking up goods. In the releasing link, the four-way vehicle will move the pallet to the designated cargo position and then align the position again. Then, the jacking mechanism will descend and the pallet will be placed on the L-beam or conveyor to complete the releasing operation. Therefore, the jacking principle of the four-way vehicle is an advanced warehousing and logistics technology. The process of picking up and releasing goods is realized through the jacking mechanism of the four-way vehicle, which has the advantages of high efficiency, flexibility, safety and accuracy.
