Abstract

The braking apparatus is provided for a shaft conveyance system in which a conveyance 18 is driven up and down an upright track 20 in the shaft 10. The braking apparatus comprises a brake 22 associated with the conveyance 18 which is operable to engage a counter-member 16 in the shaft 10 to hold the conveyance 18 at a chosen elevation on the track 20. A load cell 34 is provided for sensing the vertical load on the brake when it is engaged with the counter-member. Also provided are means operable in response to the load cell to disengage the brake from the counter-member when the load cell senses a predetermined load on the brake.
