    摘要： A rock bolt 10 comprising: an elongate, generally circular tube 12, the tube 12 having a leading end 14 and a trailing end 16, an expander mechanism 18 disposed within the tube 12 in the region of the leading end 14, an elongate tendon 28 disposed longitudinally within the tube 12 and in connection at or towards a first end 26 of the tendon 28 with the expander mechanism 18 and in connection at or towards a second 38 and opposite end of the tendon 28 with an anchor arrangement 30 positioned at the trailing end 16 of the tube 12, the tendon 28 being actuatable to actuate the expander mechanism 18 and to remain connected between the expander mechanism 18 and the anchor arrangement 30 while the expander mechanism 18 is actuated, wherein the anchor arrangement 30 includes a couple 44, 54, 66 which, under tensile loading of the tendon 28, has a first mode of operation that allows movement of the anchor arrangement 30 axially away from the trailing end 16 of the tube 12 and enabling further expansion of the expander mechanism 18, and a second mode of operation that couples the anchor arrangement 30 to the tube 12 preventing further movement of the anchor arrangement 30 axially away from the trailing end 16 of the tube 12.

    摘要： A wear member assembly (10) has a wear member (22), a wear member receiver (20) with at least first and second contact portions and at least one aperture (80) to receive at least one wear member locating member (26) of the wear member. An attachment mechanism (44,46) releasably attaches the wear member to the receiver has at least one moveable attachment member (44) and at least one respective fastening means (44). Actuation of each of the fastening means moves the associated attachment member to apply a retaining force to one of the contact portions of the receiver and causes the respective wear member locating member to apply a retaining force to the other of the contact portions of the receiver. At least one of the receiver first and second contact portions has a sloped or tapered face (54,58) and the corresponding wear member locating member (26) or attachment member (44) has a slope or taper (52,56) such that contact between the wear member locating member slope/taper or attachment member slope/taper and a corresponding one of the wear member receiver sloped/tapered contact portions causes the wear member to positively locate to the receiver when the releasable fastening means is actuated thereby releasably retaining the wear member to the outer surface of the earth moving apparatus member.

    摘要： A rock bolt 10 comprising: an elongate, generally circular tube 12, the tube 12 having a leading end 14 and a trailing end 16, an expander mechanism 17 disposed within the tube 12 in the region of the leading end 14, an elongate tendon 22 disposed longitudinally within the tube 12 and in connection at or towards a first end of the tendon 22 with the expander mechanism 17 and in connection at or towards a second and opposite end of the tendon 22 with an anchor arrangement 43 positioned at the trailing end 16 of the tube 12, the tendon 22 being actuatable to actuate the expander mechanism 17 and to remain connected between the expander mechanism 17 and the anchor arrangement 43 while the expander mechanism 17 is actuated, wherein the tube 12 has an opening 26 in the region of the leading end 14 and the expander mechanism 17 includes first and second cooperating expander elements 18, 20, in which the first expander element 18 is attached to an end of the tendon 22 for movement axially within the tube 12 towards the anchor arrangement 43 upon actuation of the expander mechanism 17 and the second expander element 20 is restrained relative to the tube opening 26, the second expander element 20 being shifted radially through the tube opening 26 as the first expander element 18 is shifted axially within the tube 12 towards the anchor arrangement 43.
