LOAD & HAUL


nickel operations. Its current occupation in the world-class nickel deposit of Weda Bay, in North Maluku, is a five-year process that began in September 2021. It will last until Q4 2026, by which time it will have produced an estimated four million tonnes of nickel. Te three Rokbak haulers were


acquired by Hillcon through Rokbak dealer PT Uniquip, an equipment supplier based in Jakarta. With Hillcon’s nearly three decades of experience in the industry and 100 ADTs in its fleet already, PT Uniquip helped highlight why Rokbak haulers stand out from the crowd.


MEETING THE CHALLENGE Te RA40s entered Weda Bay in February 2022. Daily operations for each RA40 begin at 7am and conclude at 6:45am the following day, across a two-shift driver pattern. Tese long hours benefit from the truck’s high-performance fluid transmission providing 6,000 hours of operating time before requiring an oil change, meaning increased productivity and uptime as well as low cost per tonne. However, it’s not unusual for the difficult conditions in this pocket of the planet to bring most operations to a standstill. Rokbak Regional Business Manager Lee Irving regularly makes visits to Indonesia, which lies right along the division between the world’s most active seismic region, the Pacific Ring of Fire, and the world’s second most active region, the Alpide belt. “Tis particular site is extremely challenging, with high levels of mud, uneven ground and precarious terrain that gets even worse when the notorious Indonesian wet season rolls around,” says Lee. “To put it mildly, when it rains, it really rains!”

But when times get tough, that’s when this trio of RA40s really excel, with the 38 tonne (41.9 US ton) hauler designed to make light work of large-scale quarry, mine and construction jobs – whatever the conditions. “With long shift patterns, we’ve been able to see first-hand the RA40’s performance and productivity in Weda Bay, with the truck’s heavy-duty axles coping extremely well against slippage and the subsidence you often find on site,” explains Uniquip sales manager Rachmad Sembiring.


A RINGING ENDORSEMENT Offering high capacity and performance, the RA40 delivers cost-effective productivity in the toughest conditions. Te high-performance engine balances controlled power with maximum fuel efficiency and the modulating transmission retarder is coupled with an


efficient exhaust brake and fully enclosed forced oil-cooled multidisc brakes for total control – even on steep inclines. “Te trucks need to be powerful, but


safe,” states Hillcon jobsite superintendent Ahmad Siswandi, who makes sure all the machines are ready to operate, serviced and maintained. He’s on-site, 12 hours a day, seven days a week, and keeps a keen eye on the Rokbak haulers. “Seeing an RA40 perform in our mud


has proven its worth, and we like that it’s a strong, powerful truck that remains the same performer in difficult conditions. “Te RA40 engine power is


exceptional, and the stability of the truck makes the operator feel secure and safe. Te instrumental panel is clear, easy and accessible, and the reverse-camera is sharp, with added versatility to operate when moving forward as well. “Te cab’s very comfortable and the air-con has stood out with praise from our operators – and in our climate that is a massive plus!” Te rebranded Rokbak ‘sand’ colour scheme has also been well received in the region, alongside the name embodying rock-solid strength, robustness, reliability and the brand’s promise to always have customers’ backs. It’s challenging sites such as Weda Bay that truly exemplify how well Rokbak delivers on its remit. “Te RA40 strikes the balance between

high performance, power, stability, safety and ease of controls and switches,” concludes Ahmad. “Te RA40 really is showing its class on site.”
