    摘要： A mechanical lifting jack (10) with a locking mechanism that arrests upward motion of the handle (22) if the handle (22) is suddenly released by the operator while raising or lowering a load. A latch (60) on the pivot attachment of the handle (22) to the lifting assembly is actuated by a lever (70) disposed at the distal end of the handle (22), and engages into a toothed safety link (42) when the lever (70) is released. In the event that the operator suddenly releases the handle (22) accidentally, the latch (60) engages the safety link (42) to arrest the upward motion of the handle (22). The invention can also be used to lock the handle (22) into an upright position alongside the vertical support (12) for compact storage.

    摘要： Disclosed is an assembly allowing a person to climb up and/or down an object, such as a high-voltage mast. Said assembly comprises an elongate, rail-type profiled element (1, 3, 5, 15, 17) that is provided with at least one guiding part (15, 17) extending along the profiled element, and a part for absorbing force transmission (3, 5, 15, 17). A climbing aid is also provided, comprising two climbing consoles (21) with one respective foot supporting area (23) and a guiding section that embraces or grips the guiding part (15, 17), and a holding section (33) which at least partly rests against or on the profiled element opposite thereto and is suitable for resting against the force transmitting part (3, 5, 15, 17) in order to absorb force transmission.

    摘要： An automatic extensible telescopic apparatus includes an internal tube inserted in an external tube. A positioning unit includes a ferrule, two fins, an axle, a toothed wheel and a first detent. The ferrule is provided on the external tube. The fins extend from the ferrule. The axle is supported on the fins. The toothed wheel is supported on the axle and includes teeth for insertion in recesses defined in the internal tube. The first detent is supported on the fins for engagement with the toothed wheel. A handle includes two leaves and a second detent. The leaves are placed between the fins and supported on the axle. The second detent is supported on the leaves for engagement with the toothed wheel. An extending unit is connected to the axle so that the extending unit rotates the toothed wheel via the axle, thus extending the internal tube from the external tube.

    摘要： A jack assembly including a telescopic column driven via a gear box, wherein: the gear box is coupled to a rotary input of a drive mechanism that extends and retracts the column; the gear box has only a single input gear and a single output gear that is coupled to the drive mechanism; and the input gear has a connector adapted to be engaged and driven by a portable, hand-held power tool. The invention also relates to a jack assembly with a gear box for use as a jockey wheel for attachment to a towed vehicle, to raise and lower a draw bar of the vehicle.
