SECTION 1

INTRODUCTION

The Marion Rotary BlastHole Drill uses a tri-cone rock bit for the drilling of holes to accept an explosive material. The denotation of the "charge" breaks the rock and loosens the overburden. The rotary bit threads to a bit stabilizer or bit sub which threads on to a drill pipe section that threads into a crossover sub in the rotary gear box and is driven by one or two direct current electric motor(s) on the rotary gear box in the mast. The rotary gear box provides torque and rotary speed to the drill bit. A roller chain hoist-pulldown system, powered by two hydraulic motors, raises and lowers the rotary gear box and provides a load (or force) to the drill bit.

The machine is equipped with an independent propel system which uses a hydraulic motor on each crawler. The operator is afforded control of each crawler separately to permit excellent machine maneuverability.

The optional automatic (or semi-autolube) lubrication system provides lubrication to critical parts of the machine when in propel mode.

The drill air compressor(s) uses a rotary vane impeller or two screw rotors to supply air down thru the drill pipe and thru the drill bit This bailing air cools the bearings in the drill bit and removes the drilled material cuttings from the hole.

The auxiliary air compressor provides pressurized air to operate the air valves and lubrication air pump. An additional discharge port is provided for attachment and use of air tools or hose for cleaning components or machinery house.

The hoist-pulldown and propel hydraulic circuits are included in the main hydraulic system. This system is powered by a 200 horsepower motor geared to two variable displacement axial piston pumps.

The auxiliary hydraulic system powers the support functions of the machine.

A house air filtering system provides clean air to the machinery house to cool the enclosed components and provide a slight pressurization to keep dust and dirt from entering. 1-1

SAFETY SUGGESTIONS

The operator controls the machine and its usefulness. The crew alone thinks for it. Safety, constantly in mind, prevents accidents. Develop good habits. Everyone has bad habits, but try to erase them quickly. Cleanliness and safety go together. A clean machine is easier to operate, inspect and maintain.

READ and OBSERVE ALL warning signs, they're placed for your health and safety.

KNOW the location of fire extinguishers.

DO NOT DRI LL or PROPEL the machine without adequate air pressure.

DO NOT LEAVE the controls without pushing the OFF BUTTON marked "ROTATION", turning BOTH brake switches to "SET" and hoist-pulldown lever to the center detent position.

DO NOT SE RVICE or lube moving parts.

PLEASE READ carefully this Manual, the Parts Book, and other manuals provided.

PLEASE LUBE regularly.

PLEASE CREATE A SYSTEMATIC maintenance procedure and follow it

PLEASE WATCH clearance when lowering mast

PLEASE OPERATE machine on as near level ground as possible.

PLEASE KEEP safe operating procedures in mind at ALL times.

CAUTION IS THE BY-WORD. Develop a feel for the machine. Try to sense failure before it arrives. Take that extra second to look again at something that seems out of place. A paint chip or bubble may be an early warning. A slight hiss may indicate a growing air leak. It's much easier to tighten a packing nut than shutdown for packing repair.

PROPERLY GROUND the power source.

WATCH AI R system performance.

CHECK pulldown chains for early signs of wear or failure that may cause permanent damage. 1-2

CHECK LIMIT switches for proper operation.

MAINTAIN correct supply of lubricant.

SUGGESTIONS FOR INSPECTION

The Marion Rotary Blast Hole Drill design and manufacture offers the latest in mining equipment standards. This machine will provide many years of service and production when afforded proper usage and maintenance. Following correct maintenance procedures is a primary requirement to achieve long trouble free service. Sections within this maintenance manual and other manuals provided explain the necessary steps to achieve maximum component life, emphasizing correct adjustment procedures, proper lubrication to use for different operating conditions and how to avoid contamination of hydraulic oils.

To protect the hydraulic and air compressor systems from excessive wear or damage from contaminated oil or dirty air, protective filters are provided. These filters requ ire periodic element replacement The condition of the hydraulic filters should be checked daily and changed as required. I nstructions for checking and changing the hydraulic filter elements are given in the hydraulic section of this manual. The air compressor intake filters should be checked daily and replaced when dirty. It is a good practice to replace the air compressor oil filter(s) at the same time the air intake filters are replaced.

Even with the best design, manufacture and maintenance possible; mechanical components with moving parts ultimately wear and require replacement. Friction forces, caused by metal to metal contact, cannot be completely eliminated even by the best lubricants and lube systems. This friction results in heat and component wear. Bearings ultimately wear out and shaft seals will leak. All rubber products ultimately, with age, lose their flexibility and requre replacement

Component rebuilding after some period of time elapses is inevitable. With the assistance of the Maintenance Manual and other technical material supplied, these components may be replaced and rebuilt for spares in the production parts warehouse, unless wear passes the tolerance permitting rebuilt performance adequate for reuse. This can be avoided with most components if wear is monitored by normal inspection and the wearing parts are replaced before irreparable damage is done. The manufacturer will not be responsible for damage incurred due to improper maintenance practices, including lack of inspection.

Parts that should be replaced during component rebuilding include: bushings, thrust washers, pins, V-belts, wear plates, brake linings, gaskets, errings, seals and other wearing parts. All components with moving parts have some wearing parts in them. Some of these comper nents are: hydraulic cylinders, pumps, motors and valves, air cylinders and valves, solenoid valves, air compressor lubrication pump, brakes, rotary air joint, and breakout tong.

Some components are subjected to wear or flexing throughout all their life and eventually reach a point where they must be replaced or rebuilt Some of these items are roller chain, roller chain sprockets, crawler shoe sprockets, crawler shoes, crawler load rollers, winch cable, hydraulic and air hose, guide rollers and hydraulic accumulator. 1-4

Minor cracks eventually occur in all steel structures, therefore, the structural components (mast, main frame, and crawelr side frames) should be periodically inspected. The inspections should be made more frequently in cold weather (below 0 degree F) since steel will become brittle and more prone to fracture. Any cracks found in the structures should be weld repaired as soon as possible. Special attention should be given to the larger structural members, such as the main frame beams. Early detection and quick repair prevents failure. A stretch, bend, or defect often shows up in the condition of the surface paint A collection of dust along a line may indicate a crack in the metal. Look closely at gusset connections and points where thin and heavy metals join. The manufacturer will not be responsible for damage incurred due to lack of structural inspections or improper weld repair.

Replacement and maintenance schedules may conform to planned shutdowns. Lack of proper lube, poor adjustments and abuse cause and speed up wear. These facts show up as the MAIN reasons for breakdown. If any part shows wear or distortion beyond expected normal wear, order replacement and quickly install. The cost of repairs is nothing when compared to breakdown cost and loss of man hours and production.

Production machines operating 24 hours, 7 days every week deserve an 8 hour inspection and cleaning every 7 days. Cleaning before inspection eliminates dirt and dust falling into machinery parts when inspection plates and covers are removed.

A solvent makes removal of the accumulation of oil and grease in the machinery house - easier.

Run the rotary gear box and propel gear box in each direction. Sound here may indicate damaged teeth on the gears. Check gear box for oi I leakage and visually inspect all seals. Check oil level with dipstick.

Check rotary gear box alignment in hoist and pulldown and examine the guide rollers for wear. Check for side to side cocking of gear box in pulldown. This cou Id indicate an unequal number of links in the two pulldown chains. Examine chains for excessive wear or failure.

Examine crawler belt for worn pins and broken keeper bolts. Check for cracked or broken shoes. Examine crawler drive sprocket for cracking or excessive wear. Check propel chain for excessive wear or failure. Examine hydraulic hoses for early signs of failure.

Check oil level in hydraulic tank, check dirty filter indicators at full system flow. Check gauges on tank for low charge pressure and high suction line vacuum.

Check and replace if necessary the inlet filter for the main air compressor. Check for proper operation of intake and discharge valves. Examine the main air piping for leaks. Check for proper lubrication. Check V-belt tension, if applicable, tighten or replace belts if needed.

1-5

Examine and readjust, if needed, the hoist pulldown and propel brakes. Look at the condition of brake lining. Check auto-lube systems for loose or broken fittings or injectors.

Secure ALL guards and safety features in place. DISCONNECT POWER SOURCE with machine shut down so electrical crew may adequately clean and inspect electrical equipment NOTE: any discolored electrical parts is a sign of overheating. In humid areas, look for fungus and mildew. Dry compressed air at LOW pressure works well for dust removal. Clean corrosion from parts, joints and connections. Retighten, where needed, any loose connections and terminals. Use of proper tools here eliminates broken terminals and terminal blocks. Replace missing or damaged tags and labels. Bundle loose wiring. Fasten ALL components and wiring in cabinets. Check that the cable armor is tight in the fixture. Look closely where wires and cables pass thru openings and gromments. Insulation damage generally occurs here. Replace grommets if needed. Arcing of motors and generators causes discolored commutators. Look at brushes and brush-holder condition. Correct brush spring tension where needed. Remember to replace ALL plugs, covers, and inspecti on plates.

Passing equipment condition reports along the line is important also. Wear patterns show up at varying degrees in time.Recording and checking these reports at a future date allows comparison and planned shutdowns. Planned repairs, parts orders and crews for a scheduled shutdown eliminates idle downtime.
