Description

Technical Field

[0001] The utility model belongs to the field of tower crane standard section hoisting, in particular to a hoisting mechanism used when hoisting an attachment rod. Background Art

[0002] When the traditional tower crane is too high, the small hook of the tower crane is used to hoist the attachment rod.
