Volvo Delivers First Next-Gen A45 Haulers in Japan
Two articulated haulers boost quarry productivity, fuel efficiency, and site safety for aggregates producer Kano Kousan in Yamaguchi. www.volvotrucks.com Japan's first two new generation Volvo A45 articulated haulers at the Kano Kousan aggregates production facility in Yamaguchi Prefecture. Kano Kousan Co., Ltd., an aggregates producer in Shunan City, Yamaguchi Prefecture, has received the first two new-generation Volvo A45 articulated haulers delivered in Japan. Supplied and supported by authorized regional dealer Daiichi Toyo Co., Ltd., the heavy-duty machines are deployed to continuously transport raw stone, overburden, and crushed aggregates across demanding quarry terrain. The upgraded A45 models feature an expanded payload capacity of 42 tonnes (up from 41 tonnes) and include Volvo's Haul Assist system with On-board Weighing as standard equipment to optimize loading cycles and eliminate carry-back. The haulers incorporate a redesigned transmission paired with a Volvo D16J engine and reinforced axles, delivering reduced fuel consumption and increased drivetrain durability. Engineered for severe surface conditions, the units utilize a dynamic 6x6 drivetrain with real-time Automatic Traction Control, standard Downhill Speed Control, and high-flotation tires. Inside the cab, enhanced sound and vibration dampening combine with an integrated camera system to minimize operator fatigue and blind-spot risks during continuous loading cycles. Additional Context This section provides technological and market background not explicitly detailed in the original release. In aggregate quarries and extraction sites, material transport typically hinges on choosing between rigid dump trucks (RDTs) and articulated haulers (ADTs). While rigid trucks offer high payload ratings on well-maintained, dry haul roads, they struggle on soft ground and steep, uneven inclines where frame twisting can induce severe mechanical stress. Articulated haulers overcome these topographical constraints through an oscillating hitch and articulated steering, which keep all six wheels in constant contact with the ground, regardless of terrain contouring. A critical mechanical advantage in modern ADT engineering is the transition from manual to automatic differential locks. Traditional systems rely entirely on operator intuition to engage dog clutches when traction begins to fail; delayed engagement causes wheel spin, excessive tire wear, and road surface rutting, while failing to disengage on dry turns creates severe driveline windup. Volvo’s Automatic Traction Control (ATC) continuously monitors wheel speeds and automatically locks the 100% mechanical dog clutches in 6x4 and 6x6 modes only when slippage is detected, decoupling them once stability returns. Paired with on-board weighing systems that communicate load status to the loading excavator via exterior signal lights, quarry operators can systematically avoid axle overloading, maximize tire lifecycles, and significantly lower the fuel consumption cost per ton of aggregate moved.
