Transport installation comprising a guide track and a car provided with gripping means cooperating with a drive cable

摘要

A transport installation comprises a guide track and at least one car which moves on the track. A circulating cable is provided near the track and a gripping device on the car grips this cable. This device comprises two gripping members movable relative to each other and urged into a closed position by a closing force developed within the car. A force distributor mechanism is disposed between at least one of these gripping members and the point at which the closing force is applied. Two force transmitting branches are coupled to the force distributor mechanism. Each transmits part of the aforementioned closing force. A first pivoting support carries one of the gripping members and has a first of these branches directly articulated to it. The othe branch is articulated to a second privoting support. On the second pivoting support are an engagement device and an abutment member. There is a first bearing surface on the first pivoting support with which this abutment member comes into contact when acted on by the part of the closing force applied to it by the second branch. It therefore urges the first pivoting support in the same direction as the first branch. There is at least one ramp member disposed in a fixed position along a predetermined section of the track. The engagement device co-operates with this ramp member so as to move the first and second pivoting supports apart.
