摘要

"Method for manual installation of pressurized expandable anchor bolts, control system for connection to a pressure source for manual installation by pressurizing expandable anchor bolts, and apparatus for installing an expandable anchor bolt by means of a pressure media device ". The present invention relates to a method for manually installing expandable anchor bolts by means of a thrust means comprising manually coupling a pressure source to an anchor bolt to be expanded. The method comprises the steps of an operator initiating a sequence whereby the anchor bolt is pressurized to a predetermined pressure, ensuring that the predetermined pressure is maintained for a predetermined period of time. The present invention is also related to such a control system and to an apparatus comprising such a control system.
