OPERATING PROCEDURE-
DO’s & DON’Ts
1. The pneumatic drill rig AirROC T25 is
solely designed for drilling holes in surface working i.e usually quarries,
open cast mines and construction engineering. Any use going beyond this shall
be considered not to be intended use. Not intended use is e.g:-
-
|
Lifting and
transport of loads.
|
-
|
Lifting and
transport of personnel.
|
-
|
Stabilization of other
equipment.
|
2. The AirROC T25 may only be operated,
serviced and repaired by personnel familiar with it and informed of the
dangers.
3. The pneumatic drill rig AirROC T25 shall be
operated only by personnel who, has been given a practical training on the rig.
Particular emphasis shall be laid on safety precautions.
4. Work to the hydraulic system shall be
carried out only by personnel with particular skills and experience.
5. Any welding shall be carried out only by an
authorised welder qualified acc. To EN 287 part -1 or equivalent.
6. Never carry out alterations or modifications
to the rig, which might affect the operating safety.
7. Make sure the required maintenance measures
acc. to the service schedule have been carried out and carry out the Daily
checks prior start the work. Never operate the rig when its safety is doubtful.
8. Always wear a hard hat, ear mufflers and
well fit clothes, Wear protective gloves when handle drill rods, coupling can
be hot, wear a breathing mask during drilling.
9. Check the vicinity of the drill rig. During
drilling and traveling there should be no unauthorized personnel around. At
critical locations, however, like close to unsecured benches, a supervisor
should be present. Care for sufficient sight. Check the travel path if
necessary.
10. Prior to pressurizing put all levers and switches
to NEUTRAL.
11. Avoid the employment of clearing agents
containing solvents (e.g. carbon tetrachloride). There are alternatives available
being much less dangerous to health and environment.
12. Never leave the rig unobserved during
drilling.
13. Always shut down the rig and depressurize the
air system before carry out any disconnection work to the pneumatic or hydraulic
system.
14. Be extremely careful searching leakages in
the pneumatic or hydraulic system. Highly pressurized liquids (Like hydraulic
oil) or pressurized air could penetrate cloths and skin and cause heavy
injuries or infections.
15 Operate the rig in daylight only.
16. During transportation and particularly during
hoisting there is an increased hazard of overturning. During hoisting the Track
oscillation shut-off valve must be in position BOTH CYLINDERS CLOSED.
17. The rig could tip over during trimmings in
extreme terrain. In order to avoid overturning during trimming:
-
|
Keep
Track oscillation shut-off valve in position BOTH CYLINDERS OPEN.
|
-
|
Lay
down feed resp. to provide an optimum center of gravity.
|
-
|
Max.
inclination in trimming direction: ± 20º solo machine (feed laid down).
|
-
|
Max.
lateral inclination : ± 20º solo machine (feed laid down).
|
-
|
Operate
the rig from the uphill side.
|
18. The rig could tip during drilling in extreme
position. In order to avoid tipping during drilling:
-
|
Keep Track
oscillation shut-off valve in position BOTH CYLINDERS CLOSED.
|
-
|
Max. inclination in
trimming direction: ± 20º.
|
-
|
Max. lateral
inclination :± 20º.
|
-
|
Operate the rig
from the uphill side.
|
19. When the drill string gets stuck never grip
the drill steel nor apply a spanner or similar tool while the rotation motor is
under pressure. The drill steel could suddenly break free and squeeze the arm
resp. toss about or fling the tool all of which could lead to severe injury or
death.
20. Before maintenance depressurize the rig.
ROCK
DRILL BBC 120F
1. Before the rock drill enters service all
the plastic guards placed in the hose nipples, venting holes and rotation chuck
should be removed. The plastic guards serve during transportation and storage
to prevent dirt and other foreign matter from penetrating the rock drill.
2. When starting up a new or newly overhauled
rock drill or one which has not been in service for a lengthy period, it is
very important that lubrication is effective from the very beginning.
To ensure satisfactory lubrication of the rock
drill, the following steps should be taken.
a)
|
Fill the lubricator with oil.
|
b)
|
Check the setting of the lubricating
valves. Normal oil consumption is 1.5 cm3 per m-of free air.
|
c)
|
Loosen the air hose at the connection of
the impact mechanism.
|
d)
|
Open the air control for the impact
mechanism to just half and let the air flow out against a board or similar
object, until oil starts to come out. This may take a relatively long time
and varies somewhat according to the hose length and size.
|
e)
|
Pour about 1 deciliter (3.5 fl.oz) of oil
directly into the connection nipple before the hose is re-connected.
|
f)
|
Check after starting up that there is oil
mixed in the exhaust air form the rock drill.
|
g)
|
Ensure the drilling equipment is in good
condition, the flushing holes in the bit and the drill. rods are not clogged
also check the shank packing.
|
h)
|
Check the impact surface of the shank
adapter is flat and at right angles to the centre line of the piston.

Recommendation
|
||||||||||||
Hydraulic
oil tank
|
Use mineral-based hydraulic oils with
good anti-wear-anti-rust, anti-oxidation and foam inhibiting properties and
with good air and water separation characteristics. Chose an oil with
viscosity grade (VG) and viscosity index (VI) in accordance with the table
below. An oil with a high viscosity index is less sensitive to the effects of
temperature.
