STANDARD UNIT DESCRIPTION
\nThe QXR 920 drills with a 3 in. to 6 in. DTH Hammer to a depth of 140 ft. (42.7 m) without reloading the carousel and to greater depth with reloading. Drill is designed to flexibly switch between Production, Pre-Split or Drain hole drilling and (with options) Reverse Circulation sample drilling. <\/p>\n
FEED ASSEMBLY
\nMast overall length is 32 ft. 7 in. (8865 mm) and 24 ft. (7315 mm) head travel. Hoisting and pulldown power provided by a chain feed system that uses a powerful hydraulic cylinder. <\/p>\n
CAROUSEL
\nThe carousel holds six rods 20 ft (6 m) long . All functions are hydraulically operated. <\/p>\n
AIR SYSTEM
\nDiesel driven Sullair Compressor producing 900 CFM (25.5 m3\/min) at 500 psi (34.5 bar) @ 1800 rpm, or 1050 CFM (29.73m3\/min) at 350 psi @ 2100 rpm, air filtration independent of engine air. Complete with safety shutdown. <\/p>\n
POSITIONING
\nFeed is mounted on a boom with a swing of 35\u00b0 to the right and 30\u00b0 to the left. Can be positioned for drilling horizontally from 4 ft. (1220 mm) to 12.5 ft. (3810 mm) above the grade. Can also be tilted 30\u00b0 left or right of the drill.<\/p>\n
CONTROLS
\nElectric\/Hydraulic controlled through the Programmable Logic Controller. Satellite hydraulic valves are located at the side of the drill for tramming and set-up and on the mast of the drill. <\/p>\n
POWER
\nCAT 3406E (C15) turbo charged after cooled diesel engine, 500 Hp “IND C” continuous set at 1800 to 2100 rpm <\/p>\n
UNDERCARRIAGE
\nCat\u00ae special tracks are mounted on an undercarriage designed jointly by Cubex and Caterpillar. The tracks have 19.7inch (500 mm) wide triple grouser shoes. Spring applied\/hydraulic release brakes. 36\u00b0. Gradability, 16 inch (406 mm) ground clearance. Track oscillation is +\/- 10\u00b0 Two (2) speed tram motors. <\/p>\n
CENTRALIZER
\nHydraulic Centralizer with a maximum opening of 7 inches. Hydraulically actuated slip plate sized to the hammer and drill pipe used. <\/p>\n
6230 TOP DRIVE
\nHydraulically driven with 4225 ft-lbs (5730 Nm) of torque @ 3000 psi. Speed is infinitely variable from 0 – 80 rpm. Top drive has a patented splined piston breakout system. <\/p>\n
Hammer Lubrication
\nPositive metering of either grease or oil. Fully automatic with 5 gallon (20 litre) reservoir. <\/p>\n
HYDRAULICS
\nTwo variable displacement, load sensing pressure compensated pumps. A third smaller pump dedicated to running a cooler fan. Oil is stored in a 110 gal (416 litre) tank. <\/p>\n
COOLING
\nMaximum ambient cooling capacity of 125 deg. F (52 deg. C) <\/p>\n
CAB
\nTwo man cab with vibration isolated seat and sound insulation. Independent boom mounted with both vertical and horizontal leveling cylinders. All functions controlled from the cab. <\/p>\n
MANUALS
