Sandvik Leopard DI650i drill rigs make first appearance in Namibia mining industry

Namibia-based KODO Drilling has taken delivery of the country’s first Sandvik Mining and Rock Solution’s Leopard™ DI650i surface drill rigs, which are set to go to work at an open-pit gold mine.

The rigs will be used as part of KODO Drilling’s down-the-hole (DTH) production drilling remit at the mine. The units arrived at the mine site in early November 2022.

According to Andries van Wyngaard, Territory Manager and Acting Managing Director at Sandvik Namibia, the contract is an important step in the company’s expansion strategy. Over the past year, its field service department has grown to seven trained full-service technicians in-country.

“As Sandvik Namibia gears up to support more equipment sales into the local market, we are grateful to KODO Drilling for their confidence in our innovative products and committed service,” van Wyngaard says. “With the values of KODO Drilling and Sandvik Mining and Rock Solutions so closely aligned – including safety and service excellence – this is a perfect fit.”

The DI650i, a diesel powered crawler mounted intelligent DTH rig, is designed for demanding production drilling applications in surface mining, according to van Wyngaard. The self-contained unit is equipped with an ergonomic iCAB operator’s cabin, fixed boom, dry dust collector and drill pipe changer – incorporating a modern design and layout.

“The rig comes with a range of new or redesigned components to boost its productivity,” he says. “It has the capacity to drill a wide variety of hole sizes from 90-165 mm. We have also run trials in Namibia with our RH560 hammer and we’ve seen exceptional performance – drilling holes from 115-203 mm.”

KODO Drilling Director, Vilho Hanghome, says his company’s progress is based on its constant drive to deliver innovative services and perform within a safe and environmentally sustainable manner.

“Having previously procured exploration rigs from Sandvik, we have valued the equipment quality and service we have received – as these have allowed us to deliver performance within budget to our clients,” Hanghome says. “We are therefore pleased to be investing in Sandvik’s state-of-the-art DTH technology and we will rely on their high level technical support going forward.”

Van Wyngaard says the contract shows KODO’s faith in Sandvik Namibia’s ability to support its DTH offering with aftermarket service. He points to the considerable interest the local market has shown in the delivery of the two rigs.

“After we signed off on the deal and sent the units off from our Khomanani headquarters in Kempton Park, many of our Namibian customers have noticed them on the road and posted excited comments online,” he says. “The mine where the rigs will operate is also looking forward to benefiting from the results of the new machines’ performance.”

Among the advantages the units offer is ground level access to all daily maintenance and service points. This makes for greater safety – as technicians do not have to climb around the machine. It also adds to productivity, as quicker maintenance means less downtime. Its silent and ergonomic cabin is a leader in the market, and boasts excellent visibility for safety and operability, according to the company.

Contributing to its low total cost of ownership are its intelligent hydraulic and compressor systems, which, it says, can deliver 38-42% improved fuel efficiency. Incorporating intelligent technology, the Sandvik DI650i rigs can accommodate scalable automation from on-board options to full automation systems.

Sandvik Namibia has made encouraging progress with recent equipment sales into Namibia, explains van Wyngaard, and he looks forward to a new era of engagement with both the surface and underground mining segments.

“Building on our long-standing relationship with KODO Drilling, we look forward to many more successful ventures with them and other customers,” he says.

Sandvik reinforces commitment to southern Africa miners with new South Africa HQ

In a strategic move that, it says, will consolidate its resources and further enhance its service to customers, Sandvik Mining and Rock Solutions has moved its South Africa headquarters to brand new, purpose-designed premises in Kempton Park near Johannesburg.

According to Simon Andrews, Managing Director at Sandvik South Africa, the state-of-the-art Khomanani facility includes three large workshop areas and office space on a 62,000 sq.m site.

“As the Tsonga name Khomanani reflects – ‘hold each other together as a unit’ – our new home unites us under one roof to collaborate, adapt and learn as we strive towards higher standards,” Andrews says. “The technical synergies of the workshops add to our commitment and capacity for local production that meets global quality requirements.”

Two of the workshops are dedicated to refurbishment and rebuilding of local equipment for the southern African region – mainly Botswana, Namibia and South Africa. This is where new standard-format equipment is configured for local use – typically including features like safety systems, lighting, toe-hitches and decals to customer specifications.

“Our remanufacturing facility allows us to completely rebuild machines to OEM standards, including the sub-assembly refurbishments on transmissions, axles, differential and pump motors,” Andrews says.

The first workshop has 23 bays for machines to be refurbished, while the second is specially equipped with 100 t capacity flooring for the heavier tracked equipment such as underground continuous miners and surface drill rigs. The layout of the site allows the heavy transport vehicles to loop in and out with equipment without needing to manoeuvre, improving workflow and efficiency, the company says.

A combination of cranes from 5 t to 30 t capacity – as well as a specialised 50 t forklift – facilitate safe and quick off-loading and reloading.

The third workshop focuses on local assembly of equipment for both South Africa as well as global markets to Sandvik’s OEM standards.

“Our investment in local manufacturing capacity is an important vote of confidence in South Africa and its mining sector,” Andrews says. “The quality of our work is also world class, allowing Sandvik to shift certain manufacturing duties from elsewhere in the world to our new facility.”

In line with Sandvik’s international guidelines, the design of Khomanani prioritises energy and water efficiency. With a shared solar photovoltaic system and use of LED light bulbs, the building is expected to achieve a 48% saving on energy, also making greater use of natural light, roof insulation and ‘low-E’ coated glass.

Water-efficient fixtures, fittings and systems, as well as rainwater harvesting, will improve water consumption levels by 42%, according to the company.
