Description
Technical field
The present invention relates to a kind of container spreader, in particular to the double casees of a kind of dedicated lightweight list of empty container are hung
Tool.
Background technique
Suspender is the critical component of container crane, and the quality and reliability of suspender directly affects the property of crane
Energy.Removable double-box hanger is the more efficient container crane of one kind of world container suspender manufacturing industry general development in recent years
Tool, it can also load and unload two 20 forty equivalent unit 40s and can be flexible at any time in addition to the repertoire for having ordinary telescopic suspender simultaneously
Ground adjusts their longitudinal spacing, to adapt to Container Yard, platform trailer and container ship to 20 forty equivalent unit 40 longitudinal direction casees
Away from requirement, this has been considerably improved the efficiency of loading and unloading of suspender, thus the deep welcome by modern container terminal.
Removable double-box hanger work is in two basic status, i.e., single case working condition and double case working conditions.Single case work
The operation for making state is identical with ordinary telescopic suspender, it adapts to 20 feet, 40 feet of collection by converting flexible beam length
The handling operation of vanning；When in double case working conditions, suspender is realized by the stretching of the twist lock for the middle part twist lock case being arranged
Double box functions.
Existing list double-box hanger is substantially to be formed for fully loaded container designs, therefore generally multiple with structure
Miscellaneous, the deficiencies of weight is big, and two container direct spacing when not can be effectively controlled double box-like states；In addition, conventional Dan Shuan
