DESCRIPTION: The 6200N is a track mounted ITH drill designed to drill with In-The-Hole hammers powered with a separate high air pressure supply.  

 

• Tracks are sealed and lubricated with a Caterpillar^® take-up system
• Shoes are triple grouser 12 in. (305 mm) wide
• Torque hubs can be disengaged to allow drill to be towed
• Brakes are spring applied/hydraulic released (SAHR)
• Gradeability is 65%
• Ground clearance is 7 in. (178 mm)
• When tramming driller stands on a tram platform located at rear of drill. Tram platform comes with railings for greater driller security

• There may be (2) two type of central stations depending on drill model
  - Slideover STD – 8 point grease station
• Synflex hosing from grease station to lubrication points

• Mast overall length is 9ft. 2 in. (2744 mm) for 4 ft. (1.2 m) rod change.
• Two (2) stinger cylinder assembly set and one (1) feed extension cylinder
• Two (2) stage telescopic feed cylinder has 84 in. (2134 mm) stroke and 15,800 lbs (70 kN) of hoisting and pull-down power
• Top drive mounting plate has long wearing replaceable sliders for positive control of top drive rotation unit movement up and down mast. V-notched sliders run on replaceable steel V-designed guide bars
• Urethane sliders are also used on mast connection plate and allow mast with V-designed guide bars to be extended easily
• Removable cutting deflector catches drill cuttings returning out of hole and discharges them through side port. Sample collection can be done at the 6-in. (152 mm) discharge port

• Hydraulic centralizer with a maximum opening of 8.5 in. (216 mm) along with a hydraulically actuated slip plate, which should be sized to drill tools used.
• Hydraulically actuated slip plate, side mounted, which should be sized to the drill tools.
• Hydraulic operation of a swing-out feature that allows passing of a 12 in. ITH hammer when swung out of the way.
• Hydraulic actuated cam lock on the swing-out
• Heavy duty for larger holes.

• Hydraulically driven by two (2) high torque motors, top drive has a torque capacity of 4225 ft-lbs. (5730 Nm) @ 3000 psi (207 bar)
• Speed is infinitely variable from 0 to 80 rpm
• Incorporated in top drive is patented splined piston breakout system, which eliminates need for wrenches to breakout drill pipe
• Cubex thread is #28 

• Water for dust suppression is injected with a hydraulic driven, positive displacement, triplex pump. Pump has a maximum capacity of 12 gpm (45 lpm) up to 700 psi (48.3 bar). Standard factory setting is 4 gpm (15.14 lpm)

• Positive metering of either:
• Grease lubricant - type 000NLG1 or
• Rock drill oil
• Total metering capacity:
• Max. 1500cc/hr (1.5 liter)
• Min. 60 cc/hr
• Two metering adjustments - manual stop on injector and cycle timer
• Fully automatic
• Five (5) gallon (20 litre) grease reservoir
• Warning light for low grease level in container and injection fault

• Feed is positioned horizontally for tramming and can be dumped for drilling from 5° below horizontal to 15° past vertical, under drill
• 360° swing of feed is accomplished with a rack and pinion rotary actuator. Actuator has a torque capacity of 150,000 in-lbs. (16,950 Nm)
• For quick positioning over hole, drill has a slide over feature with 28.5 in. (724 mm) of travel
• Feed is extended to bring it in contact with rock face using feed extension cylinder (54 in. (1371 mm) of stroke
• Fixing of feed is done with stinger cylinder assembly, which has two (2) opposite acting cylinders. These cylinders are integral load check cylinders which can be extended 2 ft. (609.5 mm) down and 6 ft. (1828 mm) up to an overall length of 17 ft. 10 in. (5436 mm)

• Four (4) independent load check hydraulic jacks with 15 ton (13.6 tonnes) capacity each and 500 mm (19.7 in.) travel.

• Heart of open loop hydraulic system is variable displacement, load sensing, pressure compensated. Pump with 140 cc/rev displacement performance will be supplied for fitment with return of current 100 cc/rev to Cubex. and has a horsepower limiting feature to prevent motor overload
• Oil is stored and cooled in 70 gal. (265 litre) tank
• Oil filtration is done three (3) times:
• First through a 10 micron fill filter
• Then through a 5 micron high pressure filter
• Finally through a 10 micron return filter

• 24 Volt electric/hydraulic controls are mounted on an articulating swing arm that allows drilling from either side of the drill
• The control panel comes with:
• On/off button and power on light
• Pressure gauges for air, hold back, pull-down and rotation
• Hold back and pull-down controls
• Controls for tramming, drilling and set up functions
• Forward rotation torque control
• Motor start/stop
• Emergency stop button

• All electrical components are enclosed in a NEMA / CEMA 4 panel
• Delta-wye starter
• Circuit breaker
• On/off and reset buttons
• Phase loss/phase reversal protection
• Motor overload protection
• Fail-safe Safety shut downs
• Low mine water pressure shut down
• Low hydraulic oil level
• High oil temperature
• Voltmeter and ammeter
• Indicator lights
• Zener diode

• Two (2) 24 volt HID work lights with 3200 lumens each
