Abstract

Ce dispositif antidérapant tiré par câbles est constitué de deux rails parallèles et d'un chariot sur lequel sont placés les porte-tuyaux. Les câbles de montée partent du chariot vers le haut du premier et du deuxième rail et les câbles de descente partent du chariot vers le bas du premier et du deuxième rail. Des treuils de levée exercent une traction sur les câbles de montée qui tirent le chariot vers le haut et des treuils de descente exercent une traction sur les câbles de descente pour tirer le chariot vers le bas.
