| description | The present invention is related to a method for manual installation of rock bolts expandable by means of a pressure media comprising manual coupling of a pressure source to a rock bolt to be expanded. The method comprises the steps of an operator starting a sequence whereby the rock bolt is pressurized to a predetermined pressure, and it being ensured that the predetermined pressure is kept for a predetermined period of time. The present invention is also related to such a control system, and an apparatus comprising such a control system.
L'invention concerne un procédé d'installation manuelle de boulons d'ancrage extensibles au moyen d'un milieu de pression, consistant en un accouplement manuel d'une source de pression à un boulon d'ancrage à étendre. Le procédé comprend les étapes effectuées par un utilisateur et consistant à démarrer une séquence permettant de mettre le boulon d'ancrage sous pression à une pression prédéterminée, laquelle est maintenue de façon garantie pendant une durée prédéterminée. L'invention concerne également un tel système de commande et un appareil comprenant celui-ci. |
