With fuel efficiency at the top of its requirements, leading copper ore producer CupruMin has purchased two Terex Trucks TR100 rigid haulers for use at the Roşia Poieni mine in Romania.

The 91-tonne capacity dump trucks were acquired by CupruMin through an open tender which saw Terex Trucks’ units selected ahead of the global top two brands. The Scottish manufacturer was officially awarded the business in January following an intense process where it eventually triumphed thanks to an attractive offer and aftermarket agreement. Terex Trucks’ bidding at the proceeding was supported by leading equipment dealer RET Utilaje.

“This contract was nothing like an ordinary sale because it was made up of so many elements,” says Razvan Popandron, area sales manager for West Romania at RET Utilaje.

“CupruMin required efficiency because fuel consumption has a big impact on the price of copper – it’s not an easy material to sell and the competition is strong. Therefore, fuel consumption was at the very top of the list, and the TR100s demonstrated that they were lighter in comparison to the competitors’ machines, and require less energy to move with or without material, which ultimately amounts to less fuel consumption.”

CupruMin purchased the TR100s to modernise its fleet and the machines are being put to work hauling overburden removal and transporting raw material to the crusher.

Well suited to the Roşia Poieni mine – which has a diameter the size of eight football pitches, and descends to more than 300 meters below the surface – the TR100’s resilient drivetrain and rear axle configuration provides excellent pulling and powerful rimpull to ensure the hauler can travel up steep inclines and through uneven ground conditions. The robust hauler features a spacious and ergonomic cab for maximum operator comfort.

Set to work a minimum of 12-hour shifts six days a week, CupruMin’s TR100s are fitted with the Cummins V12 37.8 litre engine that reaches 783 kW (1050 hp) and maximum torque of 4,631 Nm. Furthermore, the front hydraulic disc brakes and rear multi-disc forced cooled brakes deliver better operator control, while the transmission retarder decreases brake wear, reducing ownership costs and increasing machine availability.

“Since the machines have been working on site at Roşia Poieni, CupruMin has expressed how well the rigid trucks are performing against the existing fleet,” says Popandron. “The TR100s are working in very harsh conditions as it’s a difficult quarry but regardless the production is moving at a great pace. We’ve also received feedback from the operators, many of which were fans of the top two brands, and they are enjoying the simplicity of the Terex Trucks units.”
