Abstract: A winch assembly for use with a tractor having a power take off (nullPTOnull) includes a winch framework releasably coupled to a rear portion of the tractor. The winch framework does not inhibit connection of an implement to a three point or drawbar hitch of the tractor. A winch having a cable reel is mounted in the winch framework and coupled to the PTO such that the cable-reel may unwind or retract a cable upon PTO operation. The winch framework may be released from the rear portion of the tractor and coupled to a storage frame mounted elsewhere on the tractor when the winch is not in use. While the winch may be connected to the PTO and used without uncoupling an implement from the tractor, the winch must be removed in order to actively couple the implement to the PTO.

Abstract translation: 用于具有动力输出（“PTO”）的拖拉机的绞车组件包括可释放地联接到拖拉机后部的绞盘架。 绞车框架不阻止工具与拖拉机的三点或牵引杆搭接的连接。 具有电缆卷轴的绞盘安装在绞盘框架中并联接到PTO，使得电缆卷筒可以在PTO操作时展开或缩回电缆。 当绞车不使用时，绞车框架可以从拖拉机的后部释放并且连接到安装在拖拉机其他地方的存储框架上。 虽然绞车可以连接到PTO并且在不从拖拉机拆卸工具的情况下使用，但是绞车必须被移除以便主动地将工具耦合到PTO。

Abstract: A lifting column, preferably for height-adjustable articles of furniture, such as beds and tables, comprises a drive unit (13), wherein extension of the column takes place with at least one flexible element (9), such as a chain, belt or the like running over a pulley wheel. The column comprises two rigidly interconnected pulley wheels (16) and two additional pulley wheels (7) which are arranged such that the four wheels form two pairs and which are rigidly connected with a flexible link in the column. The flexible element runs over each of the two pairs of pulley wheels. One run of the flexible elements between two pulley wheels is fixed to a link in the column, while the other run is fixed to a subsequent link. When the column is subjected to moment loading, the forces will compensate each other fully or partly because of the rigid interconnection between the two sets of pulley wheels (16). The column is hereby very rigid.

Abstract: A safety device for a winch for minimizing line whipping when the line improperly releases. A weight is coupled to the line at a selected region on the line when the line is extended from the winch to winch an object. When the extended line suddenly releases the weight provides a weighted pivot for the released cable. The safety method provides coupling a weight to the line and, locking the weight at a selected region of the line when the line is extended from the winch for winching. When the extended line suddenly releases the locked weight provides a weighted pivot for the released cable.

Abstract: A device for heaving in and paying out a chain by means of a hydraulic cylinder (5) which by means of gripping devices (2) engages the chain (11, 12) and lifts or lowers the chain a given distance while the locking device (10) is deactivated. The structure comprises a frame (8) provided with a lower locking device (10), a chain wheel (6) guiding the chain (11, 12), and an upper gripping device (2) mounted in a bracket (1) which is connected to the rod head of the hydraulic cylinder (5) and the central axle (7) of the chain wheel (6). The lower locking device is formed by two pawls (10) which are pivotally mounted on separate pins. These pawls (10) engage under a chain link (12) and hold it securely. The upper gripping device is formed by at least one pawl (2) which, together with a chain wheel (6) having pockets for the chain (11,12), engages under a vertical chain link (11) . In order for the gripping device to be able to lift or lower the chain, the hydraulic cylinder (5) has a pivotal attachment (4) supported in the frame (8), and the end of its piston rod has a head that can be supported on the same pivot pin (3) as the pawl (2) of the gripping device, or on a separate pivot pin.
