An endless conveyor comprising an endless main driving member guided along the path of the conveyor and pivotally coupled to a load carrier which is also pivotally connected to an endless control member, the main and control members being guided with respect to each other such that the attitude of the load carrier is under positive control throughout its travel along the conveyor path, and is varied in dependence on the relative distance between the main driving member and the control member. The control member is displaced with respect to the path of the main driving member by an amount equal to the effective length of the connection between the carrier pivot axis and the control member in each region of the conveyor where the load carrrier is horizontal. The load carrier is coupled to the control member by means which adjust the effective length of the coupling where the load carrier is being pivoted between two limit positions. |
