Abstract
One of the most important problems met in cable downward installations is the considerable unbalance between tensions of two cable bits caused by load variation. This variation mainly caused by downward cable bit mass which induces amplitude in torque variation applied to control group. To maintain skip speed in recommended limits and limit the motor drive power as well as operation mode, dynamic balancing of downward system is carried out. This system acts as to limit the difference between tensions of the two downward system cable bits. In this study, it is recommended the application of downward track having a variable slope angle to realise a dynamic balancing system. Thus, because of track curvilinear shape, the decomposition of forces acting on each cable bit is such that to realize tensions equality between the two cable bits. The other advantage of this balancing type is the application of a constant braking torque which is an important factor for the choice and rational use of control group.
