This Li'i'inuung b: ii'.ir: ht sica on balance weights and in particular on weights such as those used in construction machinery intended for heavy work, e.g. B, for cutting out, lifting and laying pipes or for other lifting and lowering work on a construction site or road.

Although it can also be used with other machines, the invention is described in a form that is suitable for use with hoisting machines which normally consist of an ocnlepper with a boom lifting device that can be lowered to move outside of and over "a

To extend the side of the tractor to lift a pipe, j to carry and / or to lay in a ditch next to which the; Vehicle is working. When the crane device is on a Extends the side of the vehicle and carries a black lasb, The vehicle tends to tip over, and around such an event To prevent it, it is customary to adhere to the ent ^ oa-öu ^ osobaben heavy weight of the vehicle, as roe the can be moved from the side of the vehicle or away from it, to create a turning force that reduces the turning force as a result of the Balances load that tends to overturn the vehicle.

The invention consists of a balancing device with a weight that is movably carried on a movable arm is, and with a Eiui'ichfcun. ^ zuu / oraruorn it./ country's weight on the arm whose ar; .. swung around its joint may change the counterbalance weight.

Movement of the weight in relation to the arm can be effected by means of an elastic connection, e.g. B. a cable that is attached to it, or by a hydraulic., Device. In the first Lall, the weight can also have a sliding element (ζ. As a platform) which is guided in the arm% n movable. The cable can latifen on a disc which is arranged in the arm and which
