2.4.2 Wagon frame with track framesThe diesel engine, chassis, dust collector, hydraulic system, air system and boom system are mounted on the wagon frame.

The wagon frame comprises a frame with the operator's cab/platform mounted on the left. Controls for tramming and drilling are installed in the operator's cab/plat-form.

The track frames are carried on journals in the wagon frame. When tramming on uneven ground the drill rig is balanced by means of two compensating cylinders.

Each track frame has its own service brake. The brakes are operated by two separate control systems.

The bodywork covers the diesel engine, the compressor, the various lubrication tanks, the valves and the hydraulic hoses. Inspection covers allow easy access to the various machine components. The covers are secured in the open position by means of gas springs.

The dust collector is mounted at the back of the rig on the right-hand side.

2.4.3 Power packThis hydraulic drill rig is powered by a turbocharged, water-cooled diesel engine.

The diesel engine is equipped with a monitoring system that includes automatic shut-down functions.

The drill rig is driven by two traction motors with gears. The traction motors with gears are mounted on the track frames.

The hydraulic pumps and the compressor are driven by a diesel engine.

2.4.6 Electrical systemThe 24 V electrical system is supplied with current by an alternator and two batter-ies.

There is a main battery isolation switch in the system which ensures that it is possi-ble to isolate the batteries from the system.

The electrical system comprises starting equipment, work lighting, electric controls and safety devices.

The emergency stops are connected in series with the diesel engine cut-out system. As soon as an emergency stop button/cable is activated, the diesel engine will be stopped immediately. Reset the emergency stop buttons/cable before restarting the engine. The engine cannot be started while one of the emergency stops is still acti-vated.

For further details, see separate wiring diagram.

For details of the diesel engine, see separate diesel engine instructions.

2.4.7 Hydraulic systemThe hydraulic system consists of oil cooler, hydraulic oil tank, valves, hoses, and five hydraulic pumps.

The five hydraulic pumps provide hydraulic pressure as follows:

2.4.8 Air systemThe air system consists of the compressor with oil separator, hoses and valves.

The compressor is driven directly by the diesel engine.

The compressor element is lubricated by an air-oil mixture. The mixture is separated in the oil separator.

The system supplies air for flushing the drill hole, cleaning the dust collector filter and for the rock drill machine's ECL lubricating system to oiling the drill steel threads.

4.1 ForewordThis chapter provides instructions for daily inspection and maintenance to be carried out by the operator before each shift.

Regarding weekly inspections and other maintenance tasks, see separate instructions “Maintenance schedules”.

4.2 Extra safety check

4.2.1 Safety

DANGER• Danger of moving parts.• Risk of serious personal injury.• Set all levers and switches in neutral position

before preparing start-up.• Perform the extra safety check without the engine

running.

DANGER• The side hatches on the drill rig are not dimen-

sioned for extra weight.• Risk of serious personal injury.• Standing, sitting or leaning on the side hatches

can result in serious injury.• The side hatches must be closed when work is

carried out on top of the rig.

19

4 Daily checks

Before each shift starts an extra and thorough visual safety check should be carried out in order to detect:

• Damage that could give rise to structural weakness or cracks.• Wear that could have the same consequences.• Cracks or fractures in materials or welded joints.If the drill rig has been subjected to abnormally high stresses, vital load-bearing components may have been damaged. From a safety viewpoint, it is therefore espe-cially important to check the following points (See Figure 13 Check points).

6 Operate the tramming levers to move the drill rig in the desired direction.

7 Operate the track oscillation switches (S176, S177 See Figure 45 Tramming con-trol panel) to move the weight of the drill rig forward and backward as appropri-ate when passing obstacles. This will maintain the rig's stability even in uneven terrain.

Note

It is extremely important to use track oscillation to maintain the stability of the drill rig when tramming in uneven terrain.

Note

A horn indicates that the drill rig is reversing.

Note

If one crawler track is operated while the other is stationary the tracks are sub-jected to unnecessary stresses and this should therefore be avoided.

6.5 Tramming - General principles

6.5.1 Tramming, generalDirect the boom system straight ahead before opening the track oscillation lock.

While tramming, the track oscillation lock must be open so that the tracks can move freely whenever there is a change in terrain. Use track oscillation to keep the chassis frame as horizontal as possible. The Boom system must be in retraction position.

Adapt the speed to the terrain. Always check the terrain where the drill rig will be maneuvered.

Track oscillation must always be open during tramming and track oscillation must always be locked during setting-up for drilling.

Tramming with the feeder in tramming position

Tramming with the feeder in vertical position and centered between the track frames.

Tramming with the feeder in vertical position must only take place between holes.

When tramming with the feeder in vertical position the feeder must always be cen-tered between the track frames with the feed front as close to the ground as possible.

7 Operate the switch (S167) to move down the suction hood into proper position to collect dust and observe the drill state.

8 Jog the lever repeatedly until the drill bit has a firm hold in the rock. Then move the drilling lever to the end position, where it is held magnetically.

.

Note

At this stage the drill lever can be released to neutral position (if collaring is unsuccessful the control lever must be moved back and the collaring process restarted).

Note

Collaring with constant feed can make the drill bit veer off in the wrong direction, resulting in hole deflection and extra strain on the drill string.

73

8 Drilling

9 High percussion can be started once homogeneous rock has been reached. This also means high feed pressure is obtained. Set switch (S446A) to position (a) to get high pressure percussion. Setting switch (4, See Figure 24 Control panel for optional equipment) can get super feed.

10 If the stone condition is not even, operate the drilling lever between position (f) and (b) to move the rock drill backwards and forwards to clean the hole.

11 In drilling process, adjust the adjusting knobs (1, 2, 3) according the stone condi-tion to get the best feed force, proper penetration and rotation speed.

Figure 63 Hydraulic pressure control panel

12 Move up the suction hood sometimes and observe the drilling scrap.

13 Drill to the required depth or until the drill cradle has reached its bottom.

14 The upper drill-steel support should open as the coupling sleeve approaches it. Continue drilling until the coupling is half way through the drill-steel support.

15 After adding a new drill steel and restarting drilling, operate the switch (S187) into position (b) to open drill-steel support temporarily allowing the coupling sleeve to pass.

Note

If water flushes out of the hole then the dust collector must be switched off.

8.2 Checks during drillingMonitor drilling performance and pay particular attention to the points below:

Should anything out of the ordinary occur, stop drilling and clear up the trouble or ask service personnel to investigate.

Rock drill:

• Abnormal impact hose vibration.– Check the pressure in the rock drill accumulators.

• Check that the shank adapter is sufficiently lubricated.– Lubricating oil/air should leak out from the shank adapter. Lubricating oil

pressure should be between 2 and 10 bar on the ECL pressure gauge.• Abnormal leakage from the rock drill.

– Stop drilling immediately and ask service personnel to investigate the cause.• Note that the shank adapter has a “float position”, i.e. it is pressed out about 4-6

mm from the frame.• If damper pressure is lower than 30 bar or higher than 120 bar, percussion will

stop automatically (For rock drill COP 3060ME).– Stop drilling immediately and ask service personnel to investigate.

Hydraulic system:

• Observe all pressure gauges.– They should not show a sudden abnormal pressure.

• Check on the display for engine and directional instruments that the hydraulic oil temperature is in the green zone.

• Check that the hydraulic oil temperature does not exceed 60 °C.The bore hole:

• If water emerges from the drill hole.– Switch off DCT to protect the filters.

8.3 Adding drill rods

8.3.1 Knocking the coupling loose1 Make sure the coupling sleeve is located at the rattling position (inside of the

upper-steel support).

2 Push the drilling control lever (A) to NEUTRAL position (b) and make sure the feed and rotation is stopped. Allow percussion to be activated for approximately 0.5 seconds if only the joint between shank adapter and drill steel shall be released for jointing further drill steels. Air leaks out through the joint when it has been released.

3 Allow the percussion to be activated 1-5 seconds if all drill rods shall be taken up and all joints shall be released. The time varies depending on the number of joints and how much they are tightened.


Note

In the event of excessive removal the drill bit may be threaded loose or the drill steel string fully threaded apart.

18 Repeat steps 2 - 17 until only one drill steel remains.

8.5 Changing drill bit

1 Operate the feeder until the spike is approximate 10 cm from the rock.

2 Make sure that the drilling lever is in NEUTRAL position.

3 Move the drill bit forward until it is pressed against the rock.

4 Switch on high pressure percussion for several seconds.

5 Switch off percussion when the drill bit has loosened. If the percussion is engaged for too long then the drill steel can detach from the shank adapter.

6 Unscrew the old drill bit by hand and replace with a new one. Use a lifting equip-ment if necessary.

Note

Observe caution when the drill bit is extracted from the hole so that it is not drawn through the drill gasket.

WARNING• Moving parts.• Risk of personal injury, clothing can be trapped.• Stop drill rotation when changing bits.

Note

Never start percussion with the drill bit free without any resistance.

8.6 Action in case of drilling problems

8.6.1 Drilling problemsIf the following trouble occurs during drilling:

• Hot coupling sleeves (loose coupling sleeves).• Difficulties in uncoupling the coupling sleeves.• Hole deflections.

8.6.2 High coupling sleeve temperature

1 Excessive coupling sleeve temperature is indicated by:

a. Measuring with a thermometer

b. Oil dripping from the rock drill vaporises on the coupling sleeve

c. The coupling sleeve changes color

2 Depending on the layers of the rock, temperature can vary even within a small area. High coupling sleeve temperature is usually due to a poor relationship between drill feed pressure, percussion pressure and rotation pressure. The fol-lowing solutions are recommended to reduce coupling sleeve temperature.

a. Check the condition of the drill bit; an over-drilled bit gives less torque in the coupling sleeve.

Grind the drill bit.

b. Change to a drill bit with ballistic buttons.

c. If the rock is too hard for ballistic bits, then...

reduce rotation speed as much as possible without causing the drill string to rotate jerkily

check the drill feed pressure and set it to the recommended value.

reduce percussion pressure to below the basic setting (5-10 bar). A reasonable reduction in penetration rate must be accepted.

Note

Coupling sleeve temperature must not exceed 120 °C (248 °F).

84

8 Drilling

d. Check and/or adjust damper pressure so that the shank adapter is in “float posi-tion”.

8.6.3 Difficulties in loosening the coupling sleeveThe best method of loosening the coupling sleeve is to “drill” the last few centime-ters without feed pressure and rotation, leaving percussion active for a few seconds to break loose the coupling sleeve.

• Make sure the RPC-F system is set correctly. An RPC-F system that is set too high causes excessive torque in the coupling sleeve.

8.6.4 Hole deflection1 Try to drill with as low a drill feed pressure as possible.

2 Check the condition of the drill bit.

3 Use TAC pipes, drop center bits.

4 Only use flushing air and rotation during overload.

5 Drill the first drill steel with reduced drilling for at least half of the drill steel in order to minimize hole deflection at the start of the hole.

In the “Angle” position (a) the upper display shows the angle of inclination and the lower display shows the lateral angle.

In the “Pause” position both displays will show “-----”

In the “Length” position (c) the displays show the penetration rate on the upper display and drill bit position (or the laser line) on the lower display.

Gradient measurement operation (HQS 10, 11 and 12 MKII)1 Set up the drill rig with the feed at roughly the location for the next drill hole.

Figure 89 Setting up

2 Set the switch (F) in the “Angle” position (a).

Note

All angles refer to the angle to which the sight is pointing. If the switch is moved to the Angle position (a) during drilling then the system will continue to measure the length of the hole being drilled.

Note

In the pause position the system stops measuring length. This could be used to stop length measurement when flushing a hole for example, providing that percussion is used as a drilling signal.

8 Change the blast direction by pressing button (D) and set the required value by turning it.

Operation hole depth and penetration rate measurement (HQS 11 and 12)The drill rig is set up in accordance with the chapter “Gradient measurement”.

1 Set the feed so that it is positioned in the right drilling angles.

2 Apply the drill bit to the collaring point.

3 Set the rocker switch (F) in position (c). Hole depth measurement now starts, counting the position of the drill bit as zero. The upper display shows the pene-tration rate and the lower display shows the position of the drill bit.

Note

If the GPS sight is fitted then the blast direction must be set in the system.

The actual direction of the carrier is shown on the upper display.

The desired blast direction is shown on the lower display.

Note

The GPS requires 4-5 minutes in order to start after being switched on. Read fur-ther under the chapter entitled GPS.
