High drilling capacity and superior hole quality
AtlasCopco's range of surface crawlers continues to raise the bar.the popular multipurpose ROC L8 drill rig has been refined to increase its performance and versatility-with an even higher capacity and greater flexibility than previous models.
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 ROCL8 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 well suited for drilling de-watering holes for pit-wall depressurisation.
Its low weight and limited dimensions makes the ROCL8 easy to move from site to site,from bench to bench. The versatility of the ROCL8 gives you unique benefits.
The ROC L8 offers you the following benefits:
n Straight,accurate blast holes for controlled fragmentation
n Improved stripping ratio through double benching and pre-splitting
n Reduction of waste extraction by increasing the spit slope angle
n Controlled dilution with reverse circulation(RC)sampling(Optional module)
n Flexibility beyond conventional mining and quarry rigs
Long life aluminium box profile hydraulic cylinder feed system with exchangeable snap on stainless steel wear protections
A selection of rotary heads for optimum use of 4-6" down-the-hole hammers
Carousel tube handling system with deep hole capacity and free selection of drill tubes.
Full-view ROPS and FOPS cabin,silenced and vibration damped
The flexibility of the ROC L8 feed swing permits inclinations of up to 30 degree forward
Full-length,spring operated canopy doors offers full access to service points.
A smart investment in power and precision
The new ROCL8 operates at up to 30bar pressure and comes with a choice 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 drilling capacity.The penetration rate of the new ROC L8 is faster than its predecessors'.Drilling capacity has been increased by higher operating pressure and a unique cylinder feeding system. The new aluminium profile and tube-handling system accommodates drill tubes of up to 140mm(5 1/2") in diameter.
DTH hammers-strikingly efficient
The ROC L8 can be equipped with a range of AtlasCopco down-the hole(DTH)hammers well known for their high performance in terms of speed,reliability and longevity. With higher penetration rates and lower fuel consumption per metre drilled,our DTH hammers make a positive impact on your bottom line.
Flexibility and mobility in focus
The ROC L8 has excellent tramming ability for quick,safe transportation between work site. For a rig its size,the ROC L8 has outstanding terrain manoeuvrability with its ideal weight distribution and low centre of gravity,generous clearance and heavy-duty tracks with 20 degrees of oscillation.
Designed to keep you up and running
Like all our crawlers,the ROCL8 is designed for easy maintenance with ready access to service points. All hoses and cables are marked at each end to coincide with the schematic drawing in spare parts lists for better trouble-shooting. The Optional fast fuel-filling system adds additional efficiency.
Steeper slopes mean better economy
Pre-split DTH drilling using the ROC L8 creates higher and narrower benches. This contributes to steeper pit slopes and less waste rock to be extracted. The advantage is a low waste-to-ore ratio,which means higher productivity and better overall pit economy. The method had been successfully used at a number of mines throughout the world.

Lifting aid
The feed-mounted service winch offers lifting capacity when loading drill tubes into the rod handling system for extended hole depth or for lifting components for service.the control is conveniently located at the break out table
Smooth bench floors
Mounted 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.
Accurate sampling
ROC L8 is designed to handle in-pi grade control for accurate geological sampling. A selection of Reverse circulation options is available for samples of varying size and quality. The pictured cone sampler is controlled from the cabin.
Increased safety
With a reverse camera,the rear terrain can be viewed on a cab-mounted monitor for increased safety while reverse tramming. The same monitor may also be connected to the optional DVD for viewing DVD discs.
