At bauma 2019, Liebherr showed its R 930 and R 926 crawler excavators. Since the beginning of the year, Liebherr has launched seven crawler excavator models under 50 tonnes. The R 930, the mid-weight model of the series, is a brand new Liebherr crawler excavator for earthmoving works.
The Generation 8 series, which has gone into production at Liebherr-France SAS in Colmar, is made up of seven models ranging from 22 to 45 tonnes: R 922, R 924, R 926, R 930, R 934, R 938 and R 945. The easy-to-transport, versatile and efficient R 930 crawler excavator is fully compatible with the requirements of customers and operators of 30-tonne machines. The machine has been designed to provide extra comfort and safety, as well as optimum ergonomics and performance.
The R 926 and the R 930 have an operating weight of between 26 and 36 tonnes, and achieve a power of 150 kW/204 hp and 180 kW/245 hp respectively. The backhoe bucket capacities vary from 0,55 m³ to 1,75 m³ on the R 926 and between 1 m³ and 2,15 m³ on the R 930. The R 926 and R 930 models are available worldwide with the relevant engines.
The digging forces and tractive forces of the undercarriage and the swing torque of the uppercarriage have been significantly increased compared to the previous generation. Thanks to these improvements, the R 926 and R 930 crawler excavators achieve a much higher level of performance on construction sites.
In conjunction with the launch of this new generation of excavators, a new work equipment concept was devised that optimises the load curve and inertia of the swivelling drive in order to reduce fuel consumption.
