Volvo A25G–A45G FS: suspension, payload and editions

G-series suspension, payload and engine editions

The A25G–A45G comparison spans different launch dates and equipment arrangements. Volvo's March 2014 announcement covers A25G, A30G, A35G and A40G, plus the A35G FS and A40G FS full-suspension versions. It does not establish the later A45G's specification.

Its A30G payload is 28,000 kg, while the A40G carries 39,000 kg: the earlier entries of 31 lb and 43 lb confuse a short-ton class with pounds. The manufacturer also describes the introduction of oil-cooled wet brakes on the smaller A25G and A30G. Volvo's original G-series announcement.

On the A25G and A30G, the PT 2116 transmission has six forward ratios and two reverse ratios. Their inline IL1 dropbox and dog-clutch differential locks are part of the traction system; they do not turn these trucks into FS models. The February 2015 equipment sheet describes front gas-hydraulic struts and a rear bogie beam.

Its emergency steering pump is driven from the dropbox rather than solely from the engine. That distinction matters when comparing a steering component with one from the larger machines. A25G/A30G, February 2015.

FS means hydraulic suspension at the rear as well as the front. Volvo's A35G FS/A40G FS document describes level sensors measuring frame movement relative to the axles, hydraulic adjustment, and cross-flow between cylinders. Its onboard weighing uses suspension pressure sensors.

A conventional bogie truck and an FS truck therefore need different suspension inspections even when their body capacities look alike. Original full-suspension explanation.

The A45G brochure distributed by CJD specifies a D16F engine and PT 2519 transmission. The Tier 4 Final A45G FS document specifies D16J and PT 2529. These are document-specific combinations, not permission to substitute one engine or gearbox across every G-series truck.

The CJD A45G has a 70-degree tipping angle; the earlier 10-degree entry was incorrect. Its 30,000 kg unloaded weight includes fluids and operator, whereas 71,000 kg is the loaded total. A45G original equipment and load states.

The A45G FS rear circuit uses separate high-pressure accumulators for loaded travel and low-pressure accumulators for empty travel. Six level sensors monitor its suspension. Its 210-litre hydraulic tank belongs to that suspension-equipped configuration.

The same sheet distinguishes the standard body's volume from the larger volume with an overhung tailgate; a tailgate volume must not be presented as additional permitted payload. A45G FS hydraulic and body arrangements.
