The embodiment of the invention provides a heavy hammer limiting device and a bridge crane, and relates to the technical field of hoisting equipment. The heavy hammer limiting device and the bridge crane comprise a limiter, a connecting rope, a first pipe fitting and a second pipe fitting, the limiting stopper and the first pipe fitting are arranged on a box girder of the crane, and the two ends of the connecting rope are connected with the limiting stopper and the second pipe fitting respectively; the second pipe fitting is in sliding fit with the first pipe fitting; when the second pipe fitting is jacked up by the lifting hook on the crane, the connecting rope is in a relaxed state, and the limiter sends a signal to the control console when detecting that the connecting rope is in the relaxed state, so that the problem that the limiter fails can be well solved.

    本发明的实施例提供了一种重锤限位装置及桥式起重机,涉及起重设备技术领域。该重锤限位装置及桥式起重机包括限位器、连接绳、第一管件和第二管件;限位器和第一管件均用于设置于起重机的箱梁上,连接绳的两端分别与限位器和第二管件相连接;第二管件与第一管件滑动配合;在第二管件被起重机上的吊钩顶起上升时,连接绳处于放松状态,限位器在检测到连接绳处于放松状态时发送信号至控制台,其能够较好地解决限位器失效的问题。
