Dynamic loading of mining hoist elements in the view of the experiment performed during regular operation of the real object

Author: S. Wolny

In the paper is presented the analysis focused on determination of forces in suspensions of tubs and counterbalance ropes in regular operation conditions.

The particular attention has been taken to the phase of the hoist start with the input displacement applied to the drive wheel.

Displacements and stresses in any section of lifting and counterbalance ropes are determined for such a situation.

Moreover these results have been verified in the experiment in the real hoist installation.

This experiment has been limited to the measurement of forces in the suspension of the tub, which starts from the shaft bottom with constant acceleration.

Determined values of loads of the tub elements in operational condition could be useful as the basis for the strength analysis of elements.
