Description

Technical Field

[0001] The utility model relates to the technical field of balance lifting tools, in particular to a balance lifting tool for hoisting containers at a wharf. Background Technique

[0002] A container spreader refers to a special spreader for loading and unloading containers. It is connected to the corner fittings of the container through the twist locks at the four corners of the end crossbeam. The driver operates to control the opening and closing of the twist locks to perform container loading and unloading operations.
