The new Volvo G-Series wheeled loaders
Featuring new engines and driveline systems for improved productivity, lower emissions, greater smoothness, serviceability and operator comfort, the G-Series is the lat- est generation of wheeled loaders from Volvo Construction Equipment. The first of the G series models – (L150G; L180G & L220G) are fitted with a Volvo 13 litre Tier 4i/Stage IIIB compliant engine that is married to drive train, hydraulics and lifting systems that are all designed and produced by Volvo to work in perfect, productive, fuel efficient, harmony. The new Tier III B engine 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.
Producing between 220 and 274 kW (300-371 hp), depending on the model, these three units provide high torque at low engine speeds. As well as meeting the low emissions requirements of the legislation, the D13 engine also leads the industry in terms of fuel efficiency, reliability and noise. A variable geometry turbocharger (VGT) has been introduced on the G-Series wheeled loaders. The
re-set the standard
VGT is designed to contin- ually 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.
The new Volvo G-series wheeled loaders boast a 20% increase in lifting force and 10% increase in breakout force. 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 20oC over previous models.
Consisting of a new torque converter with Lock Up and free wheel stator, Optishift is a new system that integrates the Volvo patented
