    • Rescuing device for rescuing persons from the chairs of inoperative chairlifts or the like in which on a supporting member rollers are provided, against which the cable carrying the chairs is pressed by a braking plate, said braking plate being movable on the supporting member in a direction normal to the extension of the cable. On the braking plate spring means are acting, which can be compressed by an adjustable lever. On the supporting member there is provided a cylinder, supported by a free-wheeling bearing rotatable in one direction of rotation and not rotatable in the other. A rope is wound around the outer periphery of the cylinder and to a first end of the rope a belt is connected such that a person to be rescued and sitting in the belt by its weight generates a frictional braking force between the rope and the outer periphery of the cylinder. A person participating in the rescuing operation can slide down an inclined cable to which the chairs are connected, while sitting on a transporting means connected to the supporting member and control its speed by operating the adjustable lever.
    • 救援人员从被设置在支撑构件辊上的不能起作用的升降椅等的椅子处救出,用于通过制动板将承载椅子的电缆按压在该支架上,所述制动板可在支撑构件上沿方向 垂直于电缆的延伸。 在制动板上,弹簧装置起作用,可由可调节杆压缩。 在支撑构件上设置有由可沿一个旋转方向旋转并且不能在另一方向上旋转的续流轴承支撑的气缸。 绳索缠绕在圆筒的外周上,并且绳索的第一端连接有皮带,使得通过其重量被救出并坐在皮带中的人在绳索和外周之间产生摩擦制动力 的气缸。 参与救援操作的人员可以在坐在与支撑构件连接的传送装置上并且通过操作可调节杆来控制其速度的同时向下滑动与椅子相连的倾斜的电缆。
