Cage 

(in mining), a hoisting device for transporting cars loaded with minerals through the main mine shaft to the surface and for lowering and raising workers, materials, and equipment. The cage is a metal compartment, with devices for guiding it along the conductors, arresting devices (gates) to prevent the cars from rolling out spontaneously, and suspension and parachute devices. The cages travel along wood or metal guides in vertical mine shafts and on rails in sloping shafts. Cages may be the tipping, nontipping, or combination type and single-stage or multistage.
