A brake device for a conveyor has two load supporting conveyor rollers rotatable to enable a load thereon to be transported along the conveyor. The load supporting rollers are movable transversely to their axes of rotation by a load passing thereover against a resilient bias into engagement with a brake roller adapted to brake rotation of the conveyor rollers. The braking force exerted by the brake roller is dependent at least in part upon the weight of the load on the conveyor rollers.
