The New Volvo E-Series Articulated Hauler
The Volvo E-Series articulated hauler includes seven (7) new models, ranging in capacity from the 26.5 ton Volvo A25E to the 43-ton Volvo A40E. All are equipped with V-ACT (Volvo Advanced Combustion Technology) Tier 3 Volvo engines that offer high torque at low revolutions to maintain fuel efficiency and reduce noise levels. Power and torque have been in the Volvo-designed and-built D16D engines of the Volvo A40E and Volvo A40E FS (power was increased 12 % and torque increased 19%. The Volvo A35E and Volvo A35E FS generate the equivalent power and torque of the now-replaced Volvo A40D articulated hauler.
The Volvo A35E, Volvo 35E FS, Volvo A40E, and Volvo A40E FS are also equipped with a new fully-automatic nine-speed fast adaptive transmission. Shafts, planetary gears and bearings are all engineered to handle the high torque produced by larger engines. An optimized gear shifting pattern has a precise overlap of ratios to provide constant power transfer. These new models also have new frames, axles, and a new single speed drop box with longitudinal differential and 100% lockup to reduce power losses and improve traction and fuel efficiency. They are also fitted with more powerful exhaust brakes and retarders, and the cooling systems have been improved to eliminate the need for additional supplemental cooling in hot climates.
The Volvo A35E and Volvo A40E are equipped with all-wheel wet disc brakes for improved stopping power and longer service life, and both carry larger body designs for easier loading and more capacity. A high dumping joint and long overhand gives the operator the ability to dump into hoppers or over an edge.
Several new body advancements are also available on the Volvo A25E and Volvo A30E haulers also available on the larger platform machines. These include a bolt-on light materials kit that increases available hauler body volume, suitable when hauling low density materials. Heavy-duty wear plates are also available as are linkage-operated overhung and for the EU market not used in the North America market tailgates. These tailgate options are linkage operated and help reduce payload spilling, particularly useful when the haul cycle involves steep, sloping, and/or uneven terrain.
The Revolutionary Volvo E-Series Articulated Hauler with Full Suspension
The new Volvo-engineered Full Suspension (FS) machine provides extraordinary off-road performance, empty or full, allowing the hauler to travel at much higher speeds which, in turn, increases productivity. When traveling empty, return trips are substantially faster due to the smooth ride and the ability to traverse the toughest conditions. Even when fully loaded, the new Volvo E-Series haulers™ ability to ˜float™ over rough ground without bouncing and rolling improves operator comfort and safety.
The new Volvo FS system has automatic leveling and stability control on all wheels and, instead of traditional rubber suspension, a hydraulic cylinder is fitted to each wheel. The system constantly monitors the load and ground conditions, adapting the suspension to fit prevailing conditions, absorbing rough spots and giving a smooth and stable ride with minimal bounding, rolling, or shaking.
This radical new design also improves safety by providing significantly more ground contact. Vibration levels are considerably lower than in conventional machines, and by providing a smoother ride, operators experience less fatigue, and efficiency and productivity increases exponentially.
The operator environment
The new Volvo E-Series articulated haulers are built with a world-class operator environment. Simplified retarder controls and exhaust brakes require less operator input, and this, combined with easier-to-read Contronics information, allows the operator more time to concentrate on what is going on outside the cab. Automatic Traction Control is standard on the Volvo A25E and the Volvo A30E for even more simplified operation. Longitudinal differential locks are applied automatically depending on conditions at hand; this allows the operator to focus even more on material delivery.
