Since purchasing their first Volvo BL71 back in 2006, civil engineering contractors Heddle Construction of Kirkwall, Orkney have been that impressed with their machine that they have replaced it with the latest B version – the Volvo BL71B.
The forty year old family business operates a whole range of plant and equipment for its wide ranging civil engineering projects on the island and decided to replace their ‘A’ version Volvo backhoe with the BL71B featuring powershift transmission and full servo hydraulic controls. “We’ve been very pleased with the original machine but immediately recognised the significant improvements made to the latest version,” says Managing Director Derek Heddle. “The machine is put to a whole spectrum of work here on Orkney and has proved to demonstrate good pushing power on the front end and responsive hydraulics for the backacter and my operators appreciate the comfortable cab and all round performance of the machine,” he continues.
The Volvo BL71B has an operating weight of 9.8 tonnes and is powered by a Volvo 5 litre Tier III low emission engine developing 94 nett h.p. The torque converter on the machine is one of the largest in the industry and has excellent peak torque and torque rise and this couple to the powershift transmission maintains progressive traction - even on steep gradients. 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 thanks to load sensing hydraulics that constantly adapt to the needs of the job in 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 redesigned Volvo CareCab on the BL71B offers 15% more space over its predecessor since the room between the operator’s seat and the left side of the cab has been increased, as has space around the excavator pilot towers, making the position change between loader and excavator easier and more convenient.
