Atlas Copco Surface Drill Rigs

ROC@L825and ROC@L830

Master of productivity and flexibility -Hole diameter 110-203 mm (45/16-8")

High drilling capacityand superior hole quality

Atlas Copco's range of surface crawlers continues to raise the bar. The popularmultipurpose ROC L8 drill rig has been refined to increase its performance andversatility - with an even higher capacity and greater flexibility than previousmodels.

You can now drill production holes, improve stripping ratio with double benching and pre-splitting, and control your dilution with

reverse circulation (RC) with a single drill rig. The ROC L8 is ideal for most applications in surface mining and quarrying,such as the drilling of production blast holes, pre-split and buffer blast holes as well as lifters. Its flexibility also makes it wellsuited for drilling de-watering holes for pit-wall depressurisation.

Its low weight and limited dimensions makes the ROC L8 easy to move tfom site to site, tfom bench to bench. The versatility

of the ROC L8 gives you unique benefits.

The ROC L8 offers you the following benefits:. Straight, accurate blast holes for controlIed fragmentation

. Improved stripping ratio through double benching and pre-splitting

. Reduction of waste extraction by increasing the pit slope angle

. Controlled dilution with reverse circulation (RC) sampling (optional module)

. Flexibility beyond conventional mining and quarry rigs

A smart investment in power and precisionThe new ROC L8 operates at up to 30 bar pressure and comes with achoice of two different drill tube lengths; with long feed for 6 meter

drill tubes or with short feed for 5 meter drill tubes and toe hole drillingcapability. The penetration rate ofthe new ROC L8 is faster than its

predecessors'. Drilling capacity has been increased by higher operat-ing pressure and a unique cylinder feeding system. The new alumini-

um profile and tube-handling system accommodates drill tubes of upto 140 mm (5 W') in diameter.

DTH hammers - strikingly efficientThe ROC L8 can be equipped with a range of Atlas Copco down-the-hole (DTH) hammers well known for their high performance

in terms of speed, reliability and longevity. With higher penetrationrates and lower fuel consumption per metre drilled, our DTH ham-mers make a positive impact on your bottom line.

Flexibility and mobility in focusThe ROC L8 has excellent tramming ability for quick, safe trans-

portation between work sites. For a rig its size, the ROC L8 has

outstanding terrain manoeuvrability with its ideal weight distribu-

tion and low centre of gravity, generous clearance and heavy-dutytracks with 20 degrees of oscillation.

Designed to keep you up and runningLike all our crawlers, the ROC L8 is designed for easy maintenancewith ready access to service points. All hoses and cables are marked

at each end to coincide with the schematic drawings in spare parts listsfor better trouble-shooting. The optional fast fuel-filling system addsadditional efficiency.

The control is convenientlylocatt:dat the break out table.

Smooth bench floorsMounted on the rotary head, a laser

receiver signals the hole depth to

the cab-mounted monitoring system

and automatically stops the drill at

a pre-set hole depth. The function

ensures smooth bench bottoms

irrespective of terrain and drill set

up.
