A CALCULATION METHOD FOR A SHOVEL-TRUCK SYSTEM WITH AN INCLINED HOIST OF TRUCKLIFT TYPE

Abstract

The proposal to apply an inclined hoist of the Trucklift type in open pit mining hung in mid-air. Although this suggestion is quite interesting, no mine around the world was interested in such an installation. It appears that one of the main reasons for which the proposal missed its aim was the lack of the method of analysis and calculation of shovel-truck systems including such a type of hoist to allow an assessment of what kind of improvement might be expected if the hoist is employed in the system. This paper shows the method of analysis and calculation of shovel-truck systems with a hoist, considering the majority of the important compenents that have an influence on the course of the operation/exploitation process of the machinery system. An example is given to add to the communicativeness of the considerations and conclusions drawn.
