超大吨位平臂塔式起重机的小车与吊钩

摘要

The paper introduces a hoist rope winding method for the super-tonnage level-buffing tower crane ,de-scribes the luffing trolley and hook based on the rope winding method , presents the construction type and structural feature ,proposes the multiplying power transform method for lifting pulley block , and proves that the rope winding method can ena-ble the tower crane to lift and change speed smoothly with the examples .%介绍了一种用于超大吨位水平臂塔式起重机的起升钢丝绳缠绕方法,给出基于该绕绳方法的变幅小车及吊钩,阐述其构造形式和结构特点,介绍起升滑轮组的倍率变换方法,并通过实例说明该绕绳方法能使塔式起重机具备较好的起升和变速能力.
