The embodiments of the invention provide a limiting heavy hammer and a crane, and relates to the field of hoisting equipment. The limiting heavy hammer comprises a heavy hammer body and a blocking piece, the heavy hammer body is provided with a channel and an opening communicating with one side of the channel, a rope body can enter or disengage from the channel from the opening under the state that the extending direction of the rope body is the same as that of the opening, and when the rope body enters the channel, the rope body simultaneously penetrates through the two ends of the channel; and the blocking piece is movably arranged on the heavy hammer body and has a first state for blocking the rope body from entering or disengaging from the channel from the opening and a second state for allowing the rope body to enter or disengage from the channel from the opening. According to the limiting heavy hammer, the rope body can be easily taken up and paid off only by slightly pressing the blocking piece with hands to be in the second state, the limiting heavy hammer does not need to be disassembled and assembled through tools in the whole taking up and paying off process, the rope body can be effectively and conveniently taken up and paid off, the rope body taking up and paying off efficiency is improved, and therefore the lifting hook replacing efficiency of the crane is improved.

    本发明实施例提供了一种限位重锤及起重机,涉及起重设备领域,限位重锤包括重锤本体和阻挡件,重锤本体设置有通道和与通道的一侧连通的开口,绳体能在保持自身延伸方向与开口的延伸方向相同的状态下从开口进入或者脱出通道,当绳体进入通道时,绳体同时贯穿通道的两端;阻挡件可活动地设置于重锤本体,阻挡件具有阻挡绳体从开口进入或者脱出通道的第一状态和允许绳体从开口进入或者脱出通道的第二状态。本限位重锤只需要用手轻轻按压阻挡件,使其处于第二状态,就可以轻松完成绳体的取放,整个取放过程由于无需借助工具对限位重锤进行拆分和组装,可以有效方便绳体的取放,提高绳体取放的效率,从而提高起重机更换吊钩的效率。
