Cable for concrete mixing machines

With the cables of concrete mixers, especially those for the Besohiekerkästen or other filling devices, it is disadvantageous that the moment the box is placed on the Underlay in the lower position, the cable winch will overrun. This creates something that is becoming loose Rope (slack rope), and loops can form on the winch drum. To be serious if possible To avoid malfunctions, therefore, very precise handling of the clutch and brake levers is necessary. The disadvantages listed also occur in the case of rope hoists of concrete mixers, which are driven by individual drives be operated. Here, too, when the Besohioker box is placed on a firm surface or a Libra slack rope, which on the one hand is avoided as much as possible must be, but on the other hand is needed again e.g. for weighing the aggregates.

The aforementioned disadvantages are free of the cable pull eliminated according to the invention in that one end of the ! Carrying rope on a spring-loaded or weight-loaded lever is attached, which automatically prevents the creation of slack rope when it is placed on a base and the like without, for example, impairing the weighing of the aggregates in the starting position.
