Methods of and apparatus are provided for placing a cover lifter at a position at which a cover for a load-carrying vehicle (such as a standard gondola car) must be lifted to form a non-load-formed peak. A web is quickly installed, and need be installed only at the locations at which there is a valley in the load. The web is placed transversely across the car generally in the horizontal plane of the top of the car. The web supports the cover lifter which is initially (during placing of the cover over the web and the loaded car) flat and generally in the plane of the top of the car. After placing the web tightly on the car, and then securely tying the cover to the car over the web, the cover lifter is raised and causes the cover to stretch in a controlled manner and form a lifter-peak, which is a non-load-formed peak at just the location at which the load did not form such a load-formed peak, but did form a valley.
Cette invention concerne des méthodes et un dispositif conçus pour mettre en place un soulève-bâche aux endroits où ladite bâche placée sur un véhicule de transport (un wagon tombereau standard par exemple) doit être relevée pour former une crête en l'absence de chargement dépassant le sommet de la caisse du véhicule. Une sangle est tendue en travers de l'ouverture supérieure de la caisse aux seuls endroits où le chargement accuse un creux. La sangle porte un soulève-bâche qui est couché sur elle (lorsqu'on place la bâche sur la caisse du véhicule), dans le plan horizontal défini par le sommet de la caisse. Après avoir bien tendu la sangle ainsi que la bâche, on relève le soulève-bâche de manière à étirer la bâche de façon contrôlée et former une crête là où il n'y a pas de chargement dépassant le sommet de la caisse.
