ABSTRACT:
Monitoring of the clamping of the grips 10 of a detachable gondola lift or chair lift is carried out when the grip passes on a ramp 18 constituted by a T-shaped section. Over a measurement section 1, the base 24 of the T is separated from the upright 26 by a notch 28 to give the base 24 a certain flexibility. The deformation of the base 24, due to the action of the grip operating lever, is measured by a proximity detector 34, which delivers a signal analyzed by an electronic circuit compensating for any drift which may occur. As a result, the invention can be applied to measure the clamping of moving vehicles in general.
