The invention discloses a crane inhaul cable mechanism and a crane. The crane inhaul cable mechanism comprises a first balance mechanism, a second balance mechanism, two parallel first connecting chain assemblies and two parallel second connecting chain assemblies. The second connecting chain assembly comprises at least one inhaul cable assembly, and each inhaul cable assembly comprises two inhaul cables parallel to each other. The first balance mechanism comprises a first balance beam, a second balance beam and two side beams with the same length; the two ends of the first balance beam are connected with the two first connecting chain assemblies correspondingly. The second balance mechanism comprises a third balance beam; the second balance beam and the third balance beam are parallel to each other, arranged at the two ends of the inhaul cable assembly respectively and connected with the inhaul cable assembly respectively. The balance beam can effectively eliminate unbalance loading and torsion caused by internal stress and manufacturing precision of the inhaul cable, the distortion phenomenon is avoided, and the service life of the connecting chain assembly is prolonged.
本发明公开了一种起重机拉索机构及起重机,包括第一平衡机构、第二平衡机构、两相互平行的第一连接链组件及两相互平行的第二连接链组件;所述第二连接链组件包括至少一组拉索组件,所述拉索组件包括两根相互平行的拉索;所述第一平衡机构包括第一平衡梁、第二平衡梁和两根等长的侧边梁;所述第一平衡梁的两端分别与两所述第一连接链组件连接;所述第二平衡机构包括第三平衡梁;所述第二平衡梁与第三平衡梁相互平行,两者分设于拉索组件的两端,并分别与拉索组件连接;本发明平衡梁能够有效消除偏载和因拉索内应力和制造精度引起的扭转,避免出现扭曲现象,提升连接链组件的使用寿命。
