摘要： The load-weighing apparatus faultlessly detects even smallest load variations in the lower load range. For this purpose wire strain gauges are mounted at structural parts or components of the elevator car and these structural parts or components are subjected to bending under the load to be weighed. The wire strain gauges are interconnected to form a bridge circuit. An amplifier circuit is connected at the output side of the bridge circuit and has a higher gain in the lower load range. When an input voltage corresponding to a predetermined load occurs at the amplifier circuit, the gain of the amplifier circuit is switched to a lower value. It is thus possible to detect loads throughout a greater range of loads.
摘要翻译：负载称重设备在较低的负载范围内无故障地检测到甚至最小的负载变化。为此，电线应变计安装在电梯轿厢的结构部件或部件上，这些结构部件或部件在待称重的负载下进行弯曲。电线应变计被互连以形成桥接电路。放大电路连接在桥接电路的输出侧，在较低的负载范围内具有较高的增益。当在放大器电路处发生对应于预定负载的输入电压时，放大器电路的增益被切换到较低的值。因此，可以在更大的负载范围内检测负载。

摘要： A shoe or friction brake having the brake levers thereof connected both at the pivotably mounted end and also at the end driven by a brake spring mutually independently of one another at the brake housing. The pivotably mounted end is connected with the brake housing by elements which have a resilient or spring action perpendicular to the direction of action of the brake spring. These resilient elements are in the form of plate springs and/or a leaf or blade spring. The bearing means for each brake lever is arranged between the plate springs. Each brake lever has operatively associated therewith a choke or reactance coil, and the choke yoke or the like is arranged at the bearing means and the choke core at the brake housing. With the brake levers located in their braking position the latter, when subjected to load, are movable perpendicular to the direction of action of the brake springs, so that the air gaps of the choke coils can be reduced or increased in size, as the case may be. The resultant voltage difference is used to control a drive motor of an elevator such that it produces a torque which relieves the shoe or friction brake.
摘要翻译：具有制动杆的制动杆或摩擦制动器在可枢转安装的端部处连接，并且在制动器壳体处彼此独立地由制动弹簧驱动的端部连接。可枢转地安装的端部通过具有垂直于制动弹簧的作用方向的弹性或弹簧作用的元件与制动器壳体连接。这些弹性元件是板簧和/或叶片或叶片弹簧的形式。每个制动杆的轴承装置布置在板簧之间。每个制动杆具有可操作地与其相连的扼流圈或电抗线圈，并且扼流圈等布置在轴承装置和制动器壳体处的扼流圈。当制动杆位于其制动位置时，后者在负载时能够垂直于制动弹簧的作用方向移动，使得扼流线圈的空气间隙可以减小或增加，因为这种情况也许。所得到的电压差用于控制电梯的驱动电动机，使得其产生减轻鞋或摩擦制动器的扭矩。
