Abstract
Description
Technical Field
[0001] This utility model relates to a vertical lifting device. Background Technology
[0002] Currently, existing technologies include: 1. Lifting mechanisms are a commonly used lifting structure with wide applications in many fields. Currently, lifting mechanisms with large lifting strokes and small lowering heights mainly include scissor fork and multi-link structures. 2. Due to their structural characteristics, traditional scissor fork and multi-link structures have relatively high starting lifting heights, making it impossible to lower the vehicle to a height below the scissor fork. 3. Because of the low starting lifting height of the transmission scissor fork structure, the angle between the lifting hydraulic cylinder or electric cylinder and the horizontal plane is small, resulting in particularly difficult starting positions. Larger hydraulic cylinders or electric cylinders are usually required. Utility Model Content
