Volvo has continued to add to its stable of new T4-I wheel loaders, rolling out the L60G, L70G and L90G, all with the company’s patented TP linkage that keeps the arms parallel through the lifting range.

The new units have a Volvo 6-liter, 6-cylinder turbocharged diesel engine, which features cooled gas recirculation and a particulate filter with active regeneration. The diesel particulate filter temporarily holds the particulate matter and then incinerates it, further reducing emissions.

The production of torque and power at low engine speeds, combined with load-sensing hydraulics, promotes work at a lower rpm, which in turn extends engine life, lowers fuel usage, and dramatically reduces noise, according to Volvo. Fuel use and noise are also reduced thanks to a hydraulically driven, electronically controlled fan, which increases fan speeds only when needed.

Volvo L60G, L70G, L90G Specifications

  L60G L70G L90G
Horsepower 161 169 173
Operating weight (lb.) 24,250 28,000 29,000
Breakout force (lb.-ft.) 18,637 21,447 31,765
Full-turn tip load (lb.) 16,402 18,651 21,010

Volvo’s L90G wheel loader also features a 23-percent increase in lifting force and 19-percent improvement in breakout force over the previous model.

Load-sensing hydraulics deliver power to hydraulic functions only when needed, eliminating unnecessary oil pumping. Fitted with high- capacity axial piston pumps with variable flow, the working hydraulic pressure has been increased from 3,771 to 4,496 psi.

Transmissions feature the Volvo Automatic Power Shift 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, power is delivered to the ground through heavy-duty wet brake axles that offer high rimpull. In difficult terrain, operators can select the differential lock in order to transfer 100 percent of the available drive to the wheels, reducing tire slippage and offering maximum traction in soft or slippery conditions. Purpose-built, durable axle housings absorb all loading from the machine, and are designed to reduce working stresses on the axle shafts.

The TP linkage combines the benefits of Z-bar and parallel linkages in one system, delivering parallel movement and high breakout force, even in the highest lift position, Volvo says.

The wheel loaders’ servo controls are mounted in an adjustable console, and pilot-operated hydraulics control attachments. An eco accelerator pedal applies an appropriate amount of mechanical back pressure, encouraging operating techniques with low fuel consumption. Fuel use is also reduced through a load-sensing steering system, which only activates when the steering wheel is turned.

A new-look engine cover also provides better ventilation of the engine compartment and access for cleaning or servicing duties. Centralized, ground-level lubrication banks lower the time spent on scheduled maintenance. All consumables, such as filters, are easy to reach and replace. The rear axles are supported on maintenance-free cradles and include greased-for-life bearings and bushings.

 
 

Now powered by a Tier 4-Final Volvo D13 engine, the EC380E has a 9 percent improvement in fuel efficiency, according to the company. 

The 38,510-pound G946C motor grader is now Tier 4-Final equipped, and features a heavy-duty circle, moldboard and drawbar, with a blade pull at base of 24,957 pounds.
