Patent number: 9091042Abstract: A wear assembly for an excavator bucket comprises a cast lip, a lower wing shroud and a retaining member. The cast lip includes two upstanding wing plates. Each wing plate has a wing face on a side of the wing plate and a plate retaining formation formed on the wing face. The plate retaining formation has a plate retaining face. The wing shroud is mounted to the wing plate. The wing shroud includes a shroud retaining formation having a shroud retaining face. The retaining member includes a first bearing formation having a first face opposing and engaging the shroud retaining face, and a second bearing formation having a second face opposing and engaging the plate retaining face. The retaining member has a longitudinal axis extending between the first bearing formation and the second bearing formation. The longitudinal axis is located in a plane substantially parallel to the wing face.Type: GrantFiled: December 21, 2010Date of Patent: July 28, 2015Assignee: CQMS Pty LtdInventors: Miguel Guimaraes, Paul Heaphy, Andrew Drager, Ben Plant, Martial Vicq, Gérard Weber

Patent number: 6889820Abstract: There is provided exciter apparatus having a cast housing (11) and mounting base (14) secured to mounts bolted to the side plates of screening apparatus. A pair of shafts are mounted for rotation in and extend out of both sides of the cast housing (11). A gear assembly is keyed to each shaft t form a gear train coupling the shafts. The outer ends of each of the shafts are provided with eccentric masses (30) aligned on their respective shafts 180° out of phase. Drive spools (35) are driven by electric motors (not shown). Coupling spools (37) are adapted to accept flexible couplings for joining exciter units together. The gears (26) comprise 9 teeth of an 18-tooth module at 325.0 mm pitch circle diameter (PCD) and 65 mm axial dimension. The lands between the teeth are at a notional diameter 262.6 mm, the teeth having a corresponding notional tooth height of 31.2 mm to the PCD.Type: GrantFiled: August 6, 2001Date of Patent: May 10, 2005Assignee: Ludowici Mineral Processing Equipment PTY LTDInventors: Peter Rubie, John Russell, Paul Dalziel, Ben Plant

Patent number: 6830155Abstract: There is provided screen apparatus comprising side walls having a lower edge portion configured to accept tubular screen support members. An upper edge extends from the inlet end of the side walls to an apex from which a declining edge extends to the foot of the side walls. The lower edge, upper edge and declining edge are each provided with edge stiffening. A torque tube is secured between the respective exciter mount castings, the torque tube and stiffened side wall being selected to provide that the first fundamental frequency mode greater than the exciter frequency is at least 2 Hz greater than the exciter frequency and the first fundamental frequency below the exciter frequency is at least 2 Hz lower than the exciter frequency.Type: GrantFiled: May 28, 2002Date of Patent: December 14, 2004Assignee: Ludowici Mineral Processing Equipment Pty Ltd.Inventors: Michael Trench, Robert John Allen, Peter Rubie, John Russell, Paul Dalziel, Ben Plant, John Oliver, Neville Warnes, Russell Taylor, John Ettingshausen, Edward McKerr
