Volvo CE has launched the 55-ton payload R60 and 65-ton R70 rigid haulers, broadening its hauling options for quarrying and lite mining. The R60 and the R70 have a body volume of respectively 36.04m³ and 42.4m³. They’re smaller in size compared to the R100, but offer many of the same features and benefits of the latest E-generation.
The choice between a rigid hauler and an articulated hauler in quarrying and mining sites depends on various factors, including the specific needs and conditions of the operation. While rigid haulers thrive on sites with wide, firm, well-maintained haul roads, where they can travel fast (up to 61km/h) over long distances, articulated haulers’ trump card is on uneven, narrow, slippery and steep haul roads, where the haul cycle is shorter. The introduction of the R60 and R70 allows Volvo to tailor hauling solutions to suit the particular site dynamics. Volvo Site Simulation service can help meet production targets, reduce CO2 emissions and boost profitability by recommending the optimal site set up/machine fleet.
The new machines are being made at Volvo CE’s Motherwell plant in Scotland, a site that for nearly 75 years has been the global heart of rigid hauler development. With a low center of gravity, balanced weight and tough-yet-flexible chassis, the R60 and R70 embody the robustness, performance and reliability that delivers low cost of operation.
Productivity
Maximizing tons of material moved per hour is a core tenet of the design of the R60 and R70. The new machines feature a V-shaped haul body, that is designed to deliver maximum load retention, while at the same time minimal material carry-back post dumping. The dumping process itself is also speedy, thanks to a fast-tip system. Providing real time insights on payload, the optional On-Board Weighing system helps operators apply the industry standard 10/10/20 payload policy – where the machine can take 10% overload for 10% of the time but should not exceed 20%.
When it comes to grip, the high drive axle multiplication ensures maximum traction, while the already efficient high-torque engine is further supported in cutting fuel consumption by the automatic adaptive gear selection offered by Volvo Dynamic Shift Control. The engine also has a selectable Eco mode that defaults to the most efficient gear, while the auto engine idle shut-down reduces engine wear, boosting fuel efficiency.
Operator Comfort and Safety
The cab is fully ROPS/FOPS certified, and access is gained from both sides via anti-slip steps. When on the move, the haulers feature gear-dependent speed control, and a selectable brake or transmission retarder. The gearbox also has overspeed protection and a neutral coast inhibitor for downhill operations. There is fail-safe braking and even a secondary steering system to keep the machine safely on the right track. Visibility is among the most important elements of safety, and the operators of the R60 and R70 have perfect vision – a result of the large windscreen and low-raked dashboard, further supported by left-positioned operator station (that aids safe passing) and 360-degree Volvo Smart View option.
Thanks to the ergonomic seating position and air-suspended seat, the operator is insulated from the world outside thanks to independent suspension, while the cab sits on vibration-damping viscous mounts. The steering is low effort, and the wheel is adjustable, while the operator can choose cab temperature thanks to a powerful air conditioning system. They benefit from ample storage space and can also choose their own entertainment, via a Bluetooth radio that can connect to mobile phones.
Easy Maintenance
One of the strengths of the R60 and R70 is their ease of maintenance. Helping to keep repair costs and downtime down, the units have long 500-hour service intervals, ground-level tagout and easy-to-reach service points. Common-sized bearings keep parts stockholding simple and cost-effective. Technology also plays a part, with on-board service diagnostics, while the CareTrack telematics system looks on from afar. These help to rapidly identify potential faults and maximize uptime.
The capacity of the R60 and R70 are well matched with the loading abilities of Volvo CE’s EC950F crawler excavator, and the L350H wheel loader.
