Volvo introduces G-series wheeled loaders

The G-series, comprising the L150G, L180G and L220G, have new engines to comply with the Stage IIIB emissions requirements that came into force on 1 January 2011.

The new machines use Volvo’s 13 litre, six cylinder turbocharged V-ACT (Volvo Advanced Combustion Technology) off-highway diesel engine, which has 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.

Producing between 220 and 274 kW (300-371 hp), depending on the model, these three units provide high torque at low engine speeds, Volvo says. 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.

Two stronger, variable displacement load-bearing axial piston pumps and hoses have been introduced to handle the increased pressures.  These provide superior 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 20^oC 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.

Up to 15% fuel savings

Consisting of a new torque converter with Lock Up and free wheel stator, Optishift is a new system that integrates the Volvo patented Reverse-by-Braking (RBB) function –reducing fuel consumption by up to 15%, it is claimed – 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 & incline performance and fuel efficiency.

The G-Series comes with electronic monitoring diagnostics. Contronics monitors functions in real time and alerts the operator if problems occur. MATRIS 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. The telematics system allows machine location and operating data to be checked over the internet.
