Volvo G-Series Wheel Loaders Reset the Standard

Wed May 04, 2011 - National Edition
Construction Equipment Guide

With a 20 percent increase in lifting force, the L150G, L180G and L220G are the foundation of the new G-Series range of wheel loaders from Volvo Construction Equipment.

Featuring new engines and driveline systems for improved productivity, lower emissions, greater smoothness, serviceability and operator comfort, the G-Series is the latest generation of wheel loaders from Volvo Construction Equipment.

These new models are fitted with a Tier IVi/Stage IIIB certified engine that is married to drive train, hydraulics and lifting systems that are all designed and produced by Volvo.

More = Power, Torque and Fuel Efficiency

The G-Series is a complete range of loaders that meet the requirements of the Stage IIIB (in Europe) and Tier IVi (in the United States) emissions legislation that came into force on Jan. 1, 2011. Part of the prestigious Red Dot design winning G-Series, the L150G, L180G and L220G are all fitted with Volvo’s 13 L, six cylinder turbocharged V-ACT (Volvo advanced combustion technology) off-highway diesel engine, which features cooled gas recirculation and a particulate filter with active regeneration. The active-type diesel particulate filter (DPF) temporarily holds the particulate matter and then incinerates it, further reducing emissions. This process is conducted without any loss of performance or operation, according to the manufacturer.

Producing between 295 to 367 hp (220 and 274 kW), depending on the model, these three units provide high torque at low engine speeds. The production of torque and power at low engine speeds, combined with load-sensing hydraulics, removes the need to overrun the engine, which in turn extends engine life as well as lowering fuel usage and dramatically reducing noise.

A variable geometry turbocharger (VGT) has been introduced on the G-Series wheel loaders. The VGT is designed to continually vary the airflow into the engine. A sliding nozzle allows the exhaust gas flowing into the turbine wheel to vary so as to provide rapid boost at low engine speeds — and to achieve and maintain high boost at higher engine speeds. This contributes to good engine response across the entire engine speed range.

More Powerful Hydraulics Cut

Cycle Times

The new Volvo G-series wheel loaders boast a 20 percent increase in lifting force and 10 percent increase in breakout force. The new improvement ensures smooth, full buckets — resulting in faster cycle times and increased productivity. Two stronger, variable displacement load-bearing axial piston pumps and hoses have been introduced to handle the increased pressures. These provide emhanced control of the load and attachments, as well as high breakout force, faster lifting and tilt functions.

A new hydraulic cooling system has been designed to reduce the working temperatures by up to 68 F (20 C) over previous models. Also, the hydraulic oil-return filter has improved from 20 micron to 10 micron to further protect the pumps from potential contamination.

All made by Volvo, the powertrain is designed to work in harmony for optimum performance. Engines, transmissions, drivelines, heavy-duty axles, hydraulics — all are optimized to not only match each other, but to ensure maximum performance and reliability. Transmissions feature the company’s Volvo automatic power shift (APS) concept, which ensures the loader always operates in the ideal gear by sensing engine and travel speed, kick-down, engine braking and other factors. Offering operators a choice of four gear shifting programs, APS results in more efficient work cycles with lower fuel consumption and wear, according to the manufacturer.

Up to 15 Percent

Fuel Savings

Consisting of a new torque converter with lock up and free wheel stator, Optishift is a new system that integrates the Volvo reverse-by-braking (RBB) function — significantly reducing fuel consumption — by up to 15 percent — as well as increasing operator comfort and driveline durability. When changing from forward to reverse (or vice versa), RBB applies the standard service brake instead of the torque converter, bringing the machine to a halt and putting less stress on the converter and transmission. OptiShift can significantly reduce fuel consumption in operations such as load and carry — as well as in short cycle loading. The driveline lock up, meanwhile, improves drive response, rimpull and incline performance and fuel efficiency.

Volvo’s torque parallel (TP) linkage combines the benefits of Z-bar and parallel linkages in one system, delivering good parallel movement and high breakout force, even in the highest lift position. Featuring fewer welds, the TP linkage has a strong and durable design.


The latest generation Volvo care cab is ROPS/FOPS approved, visibility in the spacious new cabin is enhanced, to the rear, to the bucket edge — and to the centrally located instrumentation. With controls that fall easily to hand, operators can breathe easily due to efficient air-management and filtering systems — and get on with the job in hand in a comfortable, clean, low-noise and vibration work environment. The servo controls are mounted on the operator seat, and include settings such as return to dig. Also, to encourage operators to work smoothly, the accelerator pedal applies an appropriate amount of mechanical back pressure, to encourage low fuel consumption operating techniques.

Caring for the Machine

The G-Series comes with advanced electronic monitoring diagnostics that are designed to prolong machine life, enhance uptime and maximize productivity. Contronics monitors functions in real time and alerts the operator if problems occur. MATRIS, meanwhile, charts and analyses data on machine handling and operation. VCADS Pro is a system that allows a machine to be fine-tuned to specific applications, further improving performance. Finally, CareTrack uses a transmitter fitted to the machine that allows the current machine data to be viewed via the internet from anywhere in the world, aiding fast decisions on maintenance and repairs.

Servicing is made easy with the G-Series, with daily pre-start items quickly checked and scheduled service items conveniently grouped together. The G-Series is fitted with a newly designed engine cover that provides better ventilation of the engine compartment. The cover can be electronically opened backwards — giving good access for fast and easy cleaning or servicing duties. Centralized, ground level lubrication banks lower the time spent on scheduled maintenance. And consumables like filters are easy to reach and easy to replace.

The G-Series comes with a large number of Volvo attachments to suit the application, including high tip and side tipping buckets. It’s not just buckets — there is a wide range of other attachments available, as well as attachment brackets that make changing tools fast and easy. All designed and approved by Volvo to work in perfect harmony with the machines’ link-arm geometry, breakout, rim pull and lifting forces.
