    • A winch including a casing for accommodating an electric motor, a gearbox and a roller for winding and unwinding a traction member. In order to provide a cost-effective flat winch which can be transported by a single person and used universally, in particular for the domestic sector, the casing has a box-like configuration to exhibit a shape and size of a suitcase or attaché case, with the casing having opposite flat outer sides, with one outer side having attached thereon a suspension member, and the other outer side being formed with an opening for passage of the traction member. The electric motor, the gearbox and the roller are arranged in the casing and extend in a common plane, with the casing including a handle to allow transport of the winch by a person. The electric motor may be designed as a universal motor, and connected via a belt drive to the gearbox which is designed as a self-locking worm drive.
    • 一种绞车,包括用于容纳电动机的壳体,变速箱和用于卷绕和退绕牵引构件的辊。 为了提供一种具有成本效益的扁平绞车,其可以由单个人运输并且被普遍使用,特别是对于家庭部门,壳体具有呈现手提箱或附件壳体的形状和尺寸的盒状构造, 壳体具有相对的平坦的外侧,一个外侧附接有悬挂构件,另一个外侧形成有用于牵引构件通过的开口。 电动机,变速箱和辊布置在壳体中并且在公共平面中延伸,壳体包括手柄以允许人运送绞盘。 电动机可以设计为通用电动机,并通过皮带传动装置连接到设计为自锁蜗杆传动装置的变速箱。

    • A brake for a hoist, includes a brake disk and a magnetic filed which is aligned transversely to the brake disk and generates a reactive force which inhibits a movement of the brake disk and is dependent on the rotation speed of the brake disk as well as a radial distance from the rotation axis. The magnetic field is formed by two magnetic poles arranged on both sides of the brake disk. A cost-efficient, compact and wear-resistant brake which operates in dependence on the rotation direction and is applicable in particular for a drive of a hoist, with the drive including a motor without generator-produced torque and/or with greatly load-dependent rotational speed, and a self-locking gear mechanism, can be implemented in such a manner that both magnetic poles are movable by the reactive force along a predetermined path from a rest position in opposition to a return force of an elastic member in rotation direction, wherein the radial distance is preset during movement along the path by a desired course of the rotation direction dependent and rotational speed dependent braking force and adjustable by the return force of the elastic member.
    • 用于起重机的制动器包括制动盘和与制动盘横向对准的磁场,并且产生阻止制动盘的移动的反作用力,并且取决于制动盘的旋转速度以及 距旋转轴的径向距离。 磁场由布置在制动盘两侧的两个磁极形成。 具有成本效益,紧凑且耐磨的制动器,其根据旋转方向操作,并且特别适用于起重机的驱动,其中驱动器包括不具有发电机产生的扭矩的电机和/或具有极大的负载依赖性 旋转速度和自锁齿轮机构可以以这样的方式实现:两个磁极可以通过反弹力沿预定路径从静止位置与弹性构件在旋转方向上的反作用力相反地移动, 其中所述径向距离在沿着所述路径运动期间由所述旋转方向依赖的和与转速相关的制动力的期望路线预设,并且可通过所述弹性构件的返回力来调节。
