Volvo B Series Backhoe Loaders

Aug. 3, 2011

Two redesigned models launch the B-Series backhoe loaders: BL60B and BL70B. Average operating weight ranges from 17,500 to 19,500 pounds, and gross power ranges from 83 to 98 horsepower.

The one piece chassis, loader arm and excavator boom are all made from high-quality steel and robotically welded for structural integrity. The loader arm has a box-welded design and is reinforced with a cross tube. The larger excavator boom has a narrow, tall arch design and uses a closed box-welded approach with fewer components and welds. The boom allows visibility into the trench, and enables closer proximity to the truck for loading. The cast iron kingpost offers flexibility of movement and swing.

Compared to previous models, the new BL60B and BL70B feature new controls. The machines are fitted with two floor-mounted ergonomic levers that give optimum grip for the operator’s hand movements when operating the excavator. The right lever is fitted with a horn for safety, and the left lever can have an optional fingertip button. This button controls the two-way auxiliary hydraulic line required when using double acting excavator attachments.

Fitted with either 16.5-inch or 18-inch front tires, these machines have a small turning radius. Helped by a new cast bucket linkage design, the bucket can rotate 205 degrees—allowing vertical digging in all positions without repositioning the machine.

The BL60B and BL70B both have the latest D5D four cylinder 4.8 liter Volvo engines, with direct injection and turbo charging. These high-torque, fuel-efficient engines meet the requirements of the Tier 3 emissions legislation. A differential lock on the rear axle is engaged via a foot switch on the side of the brake pedal and provides maximum rear wheel grip over slippery surfaces.

Both the loader and excavator benefit from flow sharing hydraulics that enable multi-functioning for efficient and smooth operation. The BL70B features load sensing hydraulics that constantly adapt to the needs of the job at hand. With oil delivery that matches the required force, there is always the speed and power required for all hydraulic functions. In applications such as load and carry, where speed is important, the system efficiently delivers the required flow.

The Volvo Care Cab has 15 percent more space than before. The room between the operator’s seat and the left side of the cab has been increased, as has space around the excavator mechanical controls or pilot towers, making the position change between loader and excavator easier and more convenient. There is also a larger area to store personal items. The seat, steering controls and instruments are all designed to lower fatigue and keep operators alert and in control.

Service and daily maintenance are made easy with the B-Series, with a one piece lifting hood and filters/service points all grouped together at ground level. Fewer greasing points and long greasing intervals also help to increase uptime. A tilting oil cooler in front of the radiator makes cleaning both the cooler and the radiator quick and easy.
