Abstract
An elevator installation has an elevator car that moves in a vertical direction along guide tracks and is braked or held at standstill by a braking equipment. The braking equipment includes at least two brake units, at least one of the brake units, but preferably each of the brake units, is provided with a wear-compensating device which, when the brake unit is opened or released, sets a clearance distance between a brake lining and an associated brake surface, which clearance arises on opening of the brake unit, in correspondence with a substantially constant value. Thereby, use may be made of customary and thus economic brake materials which may wear during braking.
