With a rope drum as well as r «it a detachable rait this connected worm wheel, aas via a screw shaft that can be arbitrarily coupled to the drive and a tendon arranged on it can be driven

Winches of this type should be built so that they uiö ^ lent can be operated by a single worker there are above all difficulties »necessary to lower the load Reversal of the direction of rotation of the cable drum in relation to the lifting movement can be easily solved, whereby this must be ensured must »that in the event of an accident of the person operating the winch Worker's load is stopped immediately and then neither one Upward or downward movement is allowed. her to Trucks or heavier tractors intended for the transport of tree trunks usually have the same standard Direction of running internal combustion engine downstream, ■ optional

"By invention, the idea was to have a rope wiaöe create, aie is trained as an operational unit tmä all devices required for rope winches, in particular those necessary for lifting and lowering the load and an upward or downward movement of the Laet only allowed »if the worker operating the winch a control device deliberately actuated.

A particularly simple construction for a winch "which these tasks meet is, there is Gessi & ss ^ _he invention" if uptilungsteile on the Schnecekenwelle each case the solid ^ a serving for lifting the first, between the drive shaft and the worm shaft arranged electromagnetic coupling and serving one for lowering A second electromagnetic fulcrum is provided, and if a Torselegeweile which can be coupled to the drive via track wheels and which is connected to the loose coupling part of the second coupling by a chain drive door is provided for lowering. For operating äex electromagnetic clutches can at AEEN for transporting Bauastämmen eligible vehicles easily the starter battery

The use of two, preferably on one each the worm shaft arranged electromagnetic clutches makes it possible in connection with the pre-existing 3 that on other, the production more expensive Tite & honor stages veraicfetet can be, because as a result of the chain drive of the Vorge! eg © i? ©! le on the second coupling it is ensured that this is reversed Direction of rotation to the first coupling used for lifting runs * The proposed arrangement also offers the possibility of riding, to provide a simple overload protection device.
