Atlas Copco’s ROC F7 surfacecrawler is an excellent example of

company philosophy. A philosophyof producing drill rigs that give the

best overall economy in terms ofthe cost per tonne of rock drilled –

drill rigs in a class of their own.The ROC F7 is available in twoversions: a single-boom model

ideal for use in quarries, anda folding-boom model with theversatility to tackle all kinds of

work site.

With the movable drill-steel support in the lowerposition, the drill rod is accurately and securelyguided, thus minimizing hole deviation andcollaring problems.

Power and economyin perfect harmony

Caterpillar diesel engineThe service life of the engine de-pends on how hard it is worked.

The ROC F7 is equipped witha water-cooled, turbo-charged CATdiesel engine of 186 kW (253HP),at maximum drilling it only uses150 kW (204HP). This guarantees alarge power reserve, which is goodnews both for engine life and fuelconsumption.

Engine exhaust emissions and en-gine noise levels are well belowthe levels prescribed by currentregulations.

The compressor withmore muscleThe ROC F7 is equipped with arenowned Atlas Copco screw com-pressor, producing at 10,5 bar(152 psi), 148 l/s (314 cfm) of freeair delivery, more than enough airto provide excellent hole flushingin the worst drilling conditions.

Strong, stable undercarriageThe underside of the frame is com-pletely sealed with flat, thick steelplates that are removable for easyaccess to the underside of the en-gine, air compressor and mainpumps. The compact robusttrack frame design offers effectiveprotection for both the traction mo-tors and the hydraulic hoses. Theoverall dimensions of all modelsare within the international limitsfor road transport.

Hydraulic winch withremote control panelTo get an optimum view duringtramming in difficult terrain theoperator can remotely control theROC F7 via a hand held controlpanel. From as far away as 10metre (33’) the operator can safelycontrol the simultaneous use of thewinch and tramming controls, plustrack oscillation and boom move-ments.

To meet new international safetystandards and requirements, theuse of the 7 tonne Atlas Copcowinch with built-in safety break is

recommended whenever theincline of the ground exceeds 20°.

Good all-terrain abilitiesThe successful harmony of size,power, machine design and weightdistribution enables the ROC F7to make its way with ease acrosseven the most difficult ground.The tracks are wide providing mini-mum ground pressure, the twotraction motors develop 38 kWeach (50 HP), producing 15 tonnesof traction power – more than thetotal weight of the machine. Thetrack oscillation of ±10° plus a lowcenter of gravity, excellent weightdistribution and ground clearanceof 405 mm (16”) allows the ROC F7to travel easily around any worksite. The choice of track shoes isdetermined by the working envi-ronment.

Triple-grouser pads are idealwhen drilling in quarries, whereassingle-grouser pads are the naturalchoice for site work, since theyoffer valuable extra traction in allconditions, even in snow and mud.

Double drill-steel supportsA good drilling result needs a perfectstart. For this reason, the ROC F7has double drill-steel supports, theupper one fixed and the lower onemovable. The operator raises andlowers the drill support from theseat in the cab.

In extremely difficult drillingconditions, such as loose or fis-sured rock, the centralizer can besupplemented with a special tubeguide for additional support of thedrill string.

The interplay between man andmachine starts in the operator’s

cab. For this reason, we have ex-pended great effort in the develop-ment of a well conceived, purpose-built cab. Even the smallest details

have been considered. Welcomeaboard a modern work station, not

only in terms of mechanical func-tion but also ergonomics, safety

and environment.

The rock drill COP 2150at the heart of the ROC F7

Separately lubricated shankadapter prolongs service life.

A shank adapter to suit thedrill steel and the pistonprovides a long life.

More production fromless powerThe piston is the part of the rockdrill which transfers energy to thedrill bit via shock waves. The char-acteristics and efficiency of theshock waves change, dependingon the characteristics of the rockdrill piston.

The ideal hammer piston in ahydraulic rock drill should there-fore be of a diameter similar to thedrill steel itself. The shock wavesfrom a long, slender piston aretransferred with less stress to thedrill steel.

Lower stresses mean smallerpower losses, and that means thatmore power reaches the rock it isaimed at.

Reflex-damping giveslonger service lifeHowever, there is a downside tothis. More force reaching the rockalso means that the return shocks

The ROC F7 is equippedwith Atlas Copco’s new 21 kW,

COP 2150 rock drills.

The development of ournew rock drill has been basedon considerable research into

how impact energy can betransferred to the drill bit asefficiently as possible, with

the minimum of stress.

Thanks to the ideal balancebetween high drill speed

and the low consumption ofdrilling accessories, you getoptimum drilling economy.

After all, there is no pointin having the profit from faster

drilling offset by increasedcosts for the drill string.

Two stroke length positions, easilychanged to better suit the rock, andobtain higher penetration.

A powerful rotation motorwith variable speed and hightorque, prevents drill jamming.

Reflex-damping which effectivelyneutralizes reflected shock waves fromthe rock and lengthens the life of thedrill steel, the feed and the boom.

are greater. The COP 2150is therefore equipped witha internal double-dampening system whichpermits greater powerlevels without increasing wear.

Precision-matchedshank adapterThe shank adapter is the compo-nent in a rock drill which is sub-jected to the greatest stresses. Forthis reason, all shank adapters aremade by Atlas Copco as originalparts.

Optional built-in extractorThe extractor is easy to engage;simply leave the impact on andreverse the feed direction and thehammer automatically hammersthe stuck drill string out of the hole.Since there is a continuous flow ofhydraulic oil through the extractor,heat problems are avoided, thuspermitting continuous use of the

extractor until the steel is free. Ifthe machine is to drill in difficultrock, where there is a high risk ofthe drill getting stuck, it makessense to choose a machine with abuilt-in extractor.

The extractor makes it possibleto use the impact energy in the op-posite direction, which minimizesthe risk of loosing the drill rodsand the hole.

Feed system with spacefor extractor unitsThe feed beam is very rugged, re-

ducing bending and twisting prob-lems, and long enough to be fittedwith a hammer-mounted drill steelextractor. The feed is also equippedwith an offset foot spike, which notonly ensures steadier drilling, butalso keeps the hole from beingcrushed and collapsed. To mini-mize wear on the beam, the cradlehas been equipped with specialsliding pieces, which may be re-placed when necessary.
