Abstract

The invention provides a free lifting double-portal frame system. The system comprises a base, an outer portal frame, an inner portal frame and a goods fork frame; the outer portal frame is fixed on the base; the inner portal frame is mounted in the outer portal frame; the goods fork frame is mounted on the inner portal frame; an inner portal frame lifting device is arranged on the inner portal frame; and a goods fork frame lifting device is arranged on the goods fork frame. The free lifting double-portal frame system is reasonable in structural design, convenient for operation, stable in operation and high in space utilization rate.

Description

technical field [0001] The invention relates to a free lifting double mast system, which is mainly used for the handling of forklifts. Background technique [0002] In material handling operations, it is often necessary to move some items to high places. Generally, manual operations are used to carry them up. However, this method of handling is inefficient, labor-intensive, and requires a large labor cost, which is not conducive to the cost control of the enterprise. . [0003] Therefore, the handling of general bulky items needs to be carried out by means of large-scale handling tools such as diesel forklifts, but the use of this handling method requires a large free area around the items being transported, which has certain limitations. [0004] The ordinary double mast system adopts the linkage structure of the fork and the mast, that is, the fork and the mast are connected by corresponding parts, and the movement of the mast drives the fork to move at the same time to a...
