The invention provides a crane indicator and a crane and belongs to the field of engineering machinery. The indicator comprises a disc body, a first pointer and at least one second pointer, and a first scale mark and at least one second scale mark are arranged on the disc body. One end of the first pointer can be connected with the disc body in a rotating mode, and the other end of the first pointer indicates the first scale mark. The second pointers are fixedly connected with the first pointer, the free ends of the second pointers indicate the second scale marks, and the second pointers are in one-to-one correspondence with the second scale marks. The rotation center of the first pointer coincides with the rotation centers of the second pointers. The first scale mark is used for marking the pitching angle of an arm support, and the second scale marks are used for marking the amplitude and/or specified hoisting weight corresponding to the arm support under the certain arm length. The angle indicator is richer in function, and thus the crane machine is more convenient to operate.

    本发明提供了一种起重机指示牌及起重机,属于工程机械领域。上述指示牌包括盘体、第一指针和至少一个第二指针,盘体上设置有第一刻度及至少一个第二刻度。第一指针的一端能与盘体可转动连接,另一端指示到第一刻度上。第二指针与第一指针固定连接,第二指针的自由端与指示到第二刻度上,第二指针与第二刻度一一对应。第一指针及至少第二指针的回转中心重合;第一刻度用于标识臂架的俯仰角度,第二刻度用于标识一定臂长下臂架对应的幅度和/或额定吊重。上述角度指示牌其功能更加丰富,使得上述起重机械更加便于操作。
