Patent number: 7320560Abstract: 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.Type: GrantFiled: May 12, 2004Date of Patent: January 22, 2008Assignee: Atlas Copco Rock Drills ABInventors: Tommy Persson, Morgan Kanflod, Fredrik Öberg, Tapio Toivonen, Niclas Örjas, Hans Gustavsson, Göran Sjöstedt

Publication number: 20040050002Abstract: The invention relates to a reinforcement device for fastening, in this context, tremendous loads to particularly weaker walls of the type wallboard coated stud frame, and to contribute to the ability of walls to resist horizontal forces. The reinforcement device comprises portions, which connect and reinforce the parts of the wall construction. Thus, exceeding a materials tensile strength can be avoided, and the forces are distributed over a larger area, wherein the resistibility thereof can be summarised to a larger resistance. In a certain embodiment the reinforcement device can be used for fastening in solid constructions, such as light concrete and hollow brick constructions.Type: ApplicationFiled: July 21, 2003Publication date: March 18, 2004Inventor: Hans Gustavsson

Patent number: 4645226Abstract: A dolly carries a fifth wheel for connecting a trailing vehicle, a drawing device (18,20,24) for pivotable connection of the dolly (8) to a drawing vehicle and elongated side supports (22) are movable from a free position to a locked position in which they form an essentially rigid connection between the dolly and a support element (24) carried by the drawing vehicle. Hereby the connection between the dolly and the drawing vehicle can be made sidewardly rigid if needed. By the side supports (22) being carried by pivotal supports (26), which allow sidewards pivoting of the side supports to the locked position, a vehicle rig, including the dolly, can maintain a maximum of allowed length both with and without sidewards rigidity.Type: GrantFiled: August 21, 1984Date of Patent: February 24, 1987Assignee: Slapvagnskopplingar ABInventors: Hans Gustavsson, Christer Bystedt
