Abstract
A shaft hoisting plant has a conveyance and an overwind brake device for the conveyance, a travel path for the conveyance, and an overwind path adjoining a lower and/or upper end of the travel path. The overwind brake device includes retaining bars arranged in pairs in a manner spaced apart from one another and extending in a longitudinal direction, energy-absorbing material arranged in the form of plates arranged one above another in the longitudinal direction between the retaining bars. A plow is movable relative to the retaining elements, such that, upon overwinding of the conveyance, the plow deforms and/or destroys the energy-absorbing material between the retaining elements.
