    • The present invention discloses a hand brake mechanism (40) having a gravity based release hold mechanism (68) with a visual indicator (134) to prevent unwanted application of the railcar brakes and indicate such release hold condition. The release hold mechanism (68) comprises a gravity based member (130) pivotally linked to a release shaft (70) preventing reverse rotation of the release shaft (70) causing an unintended take-up of the chain (37). A detent retaining device (100) disposed within the railcar hand brake housing (14) further provides improved reliability of the operation. The gravity based member (130) incorporates an indicator portion (132) having a reflective coating to indicate such release hold position of the railcar hand brake (10).
    • 本发明公开了一种具有重力的释放保持机构(68)的手制动器机构(40),其具有视觉指示器(134),以防止不必要地施加轨道车辆制动并指示这种释放保持状态。 释放保持机构(68)包括枢转地连接到释放轴(70)的重力基部件(130),防止释放轴(70)的反向旋转,导致链条(37)的意外吸收。 设置在轨道车辆手制动器壳体(14)内的止动保持装置(100)进一步提供了操作的可靠性。 重力基构件(130)包括具有反射涂层的指示器部分(132),以指示该轨道车辆手制动器(10)的这种释放保持位置。
