Problems solved by technology

Its disadvantages: the price is higher than that of slings and wire ropes; the weight is too large
At present, the production and development of spreaders used in port operations are mainly aimed at container lifting. The lifting of containers is realized by matching with various land lifting equipment. There are very few spreaders in other fields. Single application scope restricts market development

Description

technical field [0001] The invention relates to a pipe-laying marine crane, in particular to a single-pipe spreader device developed for container lifting. Background technique [0002] The spreader refers to the device for hoisting heavy objects in the hoisting machinery, which is widely used in the hoisting industry. Chain spreaders such as hooks are commonly used in spreaders. Lifting suction cups, clamps and forks can be used as special spreaders on the crane for a long time, and can also be used as replaceable auxiliary spreaders hanging on the hook for temporary use. They are often used in multi-cargo warehouses and yards to improve work efficiency. The spreader for grabbing bulk materials is generally a grab bucket with a jaw plate that can be opened and closed, and an electromagnetic chuck can also be used to absorb magnetic materials such as metal chips. Commonly used spreaders for lifting fluid materials are buckets and hanging tanks. Generally, molten steel or ...
