ABSTRACT:
A movable load exerts varying static and dynamic forces which need to be counteracted with a minimum expenditure of energy. A counterweight connected to the movable load consists of two groups of counterweight components, wherein during movement of the load component weights in the second group are raised with respect to component weights in the first group when the counterweight is at its lowest position, or by the same absolute displacement during counterweight ascent whereby the energy introduced into the system equals the product of the total weight of components in the second group times the distance of lifting whereby the purpose of energy introduction is to counteract frictional losses of a variably counterweighted system maintaining cyclic controlled motion of the load system as desired.
