Master of quarry blast hole drilling

Hole diameter 92mm-152mm

 

ROC L6²⁵& ROC L6³⁰are high-capacity down-the-hole crawler drills primarily designed for quarry blast hole drilling in virtually all types of rock formations for aggregate production and limestone for cement production. Fitted with Atlas Copco’s high pressure compressors, 25 and 30 bar, and powerful CAT C11 and C13 diesel engines the ROC L6 series is also appreciated in mining operations and coal over- burden drilling thanks to its flexibility and overall drilling capacity and economy.

The ability to drill in different angles and to accurately set the hole inclination and control the depth of the hole contributes to the overall economy of the operation. The boom and feed movements of ROC L6 offers excellent flexibility for vertical, horizontal and angle drilling. A well balanced design and limited transport dimensions makes the rig movement smooth and transport from site to site easy.

Efficient utilisation of hammer capacity through a unique cylinder feed system Productivity beyond conventional rigs using down-the-hole hammers Transport configuration ideal for single or multi site operations Straight accurate blast holes for controlled fragmentatoin Deep hole drilling capacity Flexible drilling angles

 

Long life aluminium box profile hydraulic cylinder feed system with exchangeable snap on stainless steel wear protections

 

Carousel tube handling system with deep hole capacity

 

A selection of rotary heads for optimum use of 3–5" down-the-hole hammers

 

Full view ROPS and FOPS cabin, silenced and vibration damped

 

Full-length, spring operated canopy doors offers full access to service points

 

The ROC L6 has excellent tramming ability for quick, safe transportation on site and between work sites. The ROC L6 features a strong single section boom design that permits the operator to position the feed for transport or drilling, precise and fast, from within the cab.

 

The ROC L6 series 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 penetration rates and lower fuel consumption per meter drilled Atlas Copco's hammers make a positive impact on your bottom line.

 

Like all our crawlers, the ROC L6 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 drawings in spare parts lists for easy trouble-shooting.

 

The electronic hole inclination and depth control instrument combined with a laser receiver (optional) ensure that all blast holes are perfectly aligned and drilled to a predetermined level irrespective of the ground conditions. With the optional GPS compass all holes are guaranteed in parallel towards the blasting direction. Mentioned features ensure even bench bottoms, controlled fragmentation, easier loading and haulage and savings in the total excavation cost.

 

 

The ROC CARE package is designed for contractors and quarries at their surface drilling operations.The package includes scheduled maintenance,rig inspections,extended warranty for all major rig components and procom.

 

The feed mounted service which offers lifting capacity when loading drill tubes into the rod handling system for extend hole depth,or for lifting of components at service.the control is conveniently located at the break out table.

 

The GPS Compass aiming device uses the GPS satellite system and enables you to lock the blast direction for every hole in the blast.GPS compass adds a new dimension to the extensive automation already available on ROCl6

 

With the back camera the rear terrain can be viewed on a cab mounted monitor for increased safety at rear tramming.the same monitor may also be connected to the optional DVD for viewing DVD discs.
