Volmaquinaria presents the G-series wheel loaders

G-series is a complete range of wheel loaders that meet the requirements of legislation concerning emission stage IIIB (in Europe) and Tier 4i (in USA) which have entered into force on January 1, 2011. All the models L150G, L180G and L220G have a diesel engine turbocharged, six cylinder and 13 litres, with V-ACT (Volvo Advanced Combustion Technology), recirculation of refrigerated gases and particles with active regeneration filter. The particulate filter (DPF) active type diesel temporarily retains the particles and then incinerated them, further reducing emissions. This process is carried out with no loss of performance or operation.

These three units produced between 220 and 274 kW (300-371 HP), depending on the model, offering a high torque at low regime of the engine. In addition to the requirements of low-emission legislation, the D13 engine also meets in terms of efficiency of fuel, reliability and noise. The generation of torque and power at low regime of the engine, in combination with the sensitive hydraulic load, eliminates the need for sobreacelerar engine, which in turn extends the useful life, reduces the use of fuel and reduces noise.

In the series wheel loaders G has introduced a variable geometry (VGT) turbocharger. The VGT is designed to continuously vary the flow of air that enters the engine. A sliding mouthpiece allows that they vary the exhaust gases flowing to the blades of the turbine in order to offer a rapid boost to low regime of the engine, and to achieve and sustain high impulse to a regime superior engine. This contributes to a good response from the engine in its range of regimes.

The new Volvo G-series loaders have a 20% increase in lifting force and a 10% improvement in tractive force. New improvement ensures that spoons work full and gently, which results in faster cycle times and higher productivity. Two bomb load of axial piston variable displacement and more resistant hoses have been introduced to withstand higher pressures. Thanks to them is achieved better control of the load and the implements, as well as a large force of boot, a faster rise and swivel functions. A new hydraulic cooling system is designed to reduce the working temperatures up to 20 ° C in relation to previous models. In addition, improved return of hydraulic oil of 20 microns to 10 micron filter, to further protect the bombs against possible contamination.

Completely made by Volvo, the Powertrain is designed to work in harmony, in order to achieve optimal performance. Engines, transmissions, drive trains, the axles for heavy work, hydraulic... all are optimized not only to be consistent among themselves, but also to ensure maximum performance and reliability. The transmissions have the unique concept of the company Volvo Automatic Power Shift (APS), which guarantees that the loader always works in progress ideal, detecting the engine and the travel speed, kick-down, the engine braking and other factors. The APS offers operators a choice of four programs of shift, resulting in more efficient work cycles with a reduced fuel consumption and less wear and tear.

Equipped with a new torque converter with stator of free wheel and locking, OptiShift is a new system that integrates the role of reverse gear by braking (BBR) patented by Volvo, significantly reducing fuel consumption (up to 15%) and increasing operator comfort and the durability of the powertrain. To change gears forward to reverse (or vice versa), the BBR applies the brake of standard service instead of the torque converter, stopping the machine and putting less effort on the converter and transmission. OptiShift can significantly reduce fuel consumption in operations such as loading and transport, as well as load of short-cycle. The blockade of the Powertrain, in turn, improves driving response, the force of traction, outstanding performance and fuel efficiency.

The kinematics Torque Parallel (TP), patented by Volvo, combines the advantages of the cinematic in Z, and the parallel kinematics in a single system, offering a good move in parallel and a high tractive force, even in the position of higher elevation. With fewer welds, TP kinematics provides a robust and durable design that is designed to withstand the toughest conditions.

The latest generation of Volvo CareCab cabins used by these wheel loaders continues to improve. Approved according to ROPS/FOPS, visibility in the new and spacious cabin on the rear, the edge of the spoon and the Central instruments is excellent. Controls placed by hand, operators can breathe easily thanks to the efficient management and air filtering systems, and continue the work in an environment that's comfortable, clean, with low noise and low vibration. The servocontroles are mounted on the seat of the operator and include settings such as return to excavation. In addition, to facilitate the work of the operators, the accelerator pedal applies an appropriate amount of mechanical counterpressure that favors a lower consumption of fuel.

G-series comes with advanced electronic monitoring diagnoses that are designed to prolong the life of the machine, increase production uptime and maximize productivity. Contronics monitors the functions in real time and alerts the operator if there are any problems. MATRIS, in turn, registers graphically and analyzes data from the management and operation of the machine. VCADS Pro is a system that allows fine adjustments in the machine for specific applications, further improving performance. Finally, CareTrack uses a transmitter coupled on the machine that allows that current data of the machine can be seen on the Internet from anywhere in the world, speeding up the taking of decisions on maintenance and repairs.

Sunsets are point-to-point made easily in the G series, you can quickly check daily checkpoints prior to the start and the pieces they need regular maintenance are grouped in a practical way. The G series has again a hood of the engine design that offers a better ventilation of the engine compartment. The hood may open back electronically, offering good access to power to carry out tasks of cleaning or implementation to quickly and easily. Banks of lubrication centralised ground-level reduces the time required for the scheduled maintenance. In addition, supplies as the filters are handmade and are easy to change.

G-series comes with a large number of implements Volvo to adapt to the application, including buckets of high dumping and side dumping. There is not only available spoons, but also implements, as well as portaimplementos that make change tools quickly and easily. All of them designed and approved by Volvo to work according to the geometry of arms of articulation of the machine, boot, traction and lifting forces.
