Liebherr Group, the Swiss manufacturer of heavy construction equipment, has begun production of its new R 926 compact excavator.
The R 926 is the latest addition to Liebherr’s fleet of compact machines in the 15 to 35 tonne category. Its Tier 4 Final engine is one of several upgrades from the preceding stage 3B models. Others include Liebherr SCR technology, improved swing torque, greater engine power and simplified maintenance.
Overall, productivity has been enhanced along with efficiency.
The new machine’s diesel engine, which satisfies Tier 4 Final emission standards, is manufactured in Liebherr’s Bulle, Switzerland, plant. With an engine power of 129 kW, it is 8 percent stronger than the engines on previous models.
The R 926 has an operating weight range between 25.4 and 29.5 tonnes, depending on which options are selected. It has a tail swing of 1.7 metres and front swing of 1.9 metres, making for a reduced swing radius of less than 4 metres—ideal for work in confined spaces.
Enhancing the R 926’s productivity are new hydraulic components and an uppercarriage swing torque of 84 kNm, a significant 18 percent improvement over the previous generation that will be particularly felt during loading processes and while working on slopes.
A broad range of options allows customers to customize each excavator according to their specific needs. For example, customers get to choose from a number of HD buckets and special tools, all manufactured in-house by Liebherr, resulting in a bucket volume range between 0.55 and 1.5 cubic metres.
Established in 1949, Liebherr Group is a global leader in the development and production of mobile cranes, tower cranes, maritime cranes, earthmoving and mining equipment, concrete technology, aerospace and transportation systems, machine tools and automation systems.
