The invention discloses a steel wire rope head hooking device, a lifting system and a crane, relates to the field of engineering machinery, and aims to reduce a rope entering angle when a steel wire rope is wound into a pulley. The steel wire rope head hooking device comprises a hooking part and a connecting part. And the hooking part is configured to be hooked with a suspension arm pulley block or a hook pulley block. The connecting part is rotatably connected with the hanging part; the connecting part is configured to be rotatably connected with the steel wire rope. According to the technical scheme, the steel wire rope head hooking device is installed at the end, away from a winch, of the steel wire rope of a lifting system, the steel wire rope head hooking device can be hooked to any needed position, the direction of the steel wire rope winding into a hook pulley block is determined, and the direction of the steel wire rope winding out of the hook pulley block can be adjusted, so that the steel wire rope can be hooked to any needed position. Therefore, the rope inlet angle of the steel wire rope can be small enough, the probability that the steel wire rope is twisted in the working process is reduced, the service life of the steel wire rope is prolonged, and damage to the steel wire rope is small.
本发明公开了一种钢丝绳绳头挂接装置、起升系统以及起重机,涉及工程机械领域,用以减小钢丝绳绕入滑轮时的入绳角。钢丝绳绳头挂接装置包括挂接部以及连接部。挂接部被构造为与吊臂滑轮组或者吊钩滑轮组挂接。连接部与挂接部可转动地连接;连接部被构造为与钢丝绳可转动地连接。上述技术方案提供的钢丝绳绳头挂接装置,其安装在起升系统的钢丝绳远离卷扬的一端,钢丝绳绳头挂接装置可以挂接在任意需要的位置,由于钢丝绳绕入吊钩滑轮组的方向是确定的,而钢丝绳绕出吊钩滑轮组的方向又可以调节,这就使得钢丝绳的入绳角能够足够小,以减少钢丝绳在工作过程中出现扭转的几率,提高了钢丝绳的寿命,且对钢丝绳的损伤小。
