Abstract

The invention consists of flotation means for correct wedging of a safety device for lifts specially designed to be situated between the guide and the lift cabin optimising space requirements, consisting mainly of the use of a set of horizontal grooves (7.1) which enable lateral displacement of the body (1) of the safety device which is laterally displaceable and able to absorb all the forces deriving from wedging at the time of stopping, as well as being provided with a seating means (1.2) specially designed to ensure the correct support of the wedge at all times.
