  • Patent number: 10358921
    Abstract: A friction bolt assembly includes: an expansible sleeve having a tubular body between leading and trailing ends, which body has a longitudinally extending formation about which the body resiliently deforms and which formation extends along at least part of the body, ending at the body leading end; a rod extending through the sleeve body and between first and second ends and on which a projecting part is defined between the trailing end of the sleeve body and the second end; an expansion element on the rod at the first end; a first load bearing formation on the projecting rod part, moveable along the projecting part to abut the sleeve trailing end; a load applicator on the projecting part of the rod; and a second load bearing formation mounted over the projecting part of the rod between the first load bearing formation and the load applicator unit.

  • Patent number: 9200514
    Abstract: A rock anchor includes a cartridge positioned in an elongate tubular body and having a rigid tubular housing. First and second compartments are defined within the cartridge. First and second adhesive components are positioned within the respective first and second compartments and are fluidly separated by a partitioning wall. A mixer is positioned within the elongate tubular body at a leading end of the cartridge. A pressing member is positioned within the cartridge towards a trailing end and includes a bladed formation which is operable to sever the partitioning wall when the bladed formation is caused to advance towards the leading end in response to fluid flowing into the cartridge, to thereby force the first adhesive component from the first compartment and the second adhesive component from the second compartment towards the leading end and into the mixer.

  • Patent number: 8985910
    Abstract: A rock anchor includes an elongate tubular body which extends between a first end and an opposing second end and a cartridge contains a multi-component adhesive system in the tubular body. The cartridge has a rigid tubular housing within which at least one compartment is defined, and in which is contained an adhesive component of the system. The at least one compartment yields to volumetrically reduce under fluid pressure created by a fluid input into the housing, to thereby extrude the adhesive components.
