Performance Comfort Liebherr wheeled excavators have the performance to get building work done faster. The above-average high lift capacity and the large digging forces deliver extraordinary productivity in application. More performance for greater efﬁciency. The newly developed Liebherr operator’s cab offers the machine operator the necessary space and comfort to make optimum use of the machine’s performance.
PAGE 4
Travel drive • Newly developed travel drive with high traction force for high travel speeds both in the plane and on gradients. • Reduces unproductive travel time between the working points and on the building site. • Faster on site. Faster productive.
PAGE 5
Performance Liebherr wheeled excavators are used on building sites all over the world, where they embody force and speed. Using Liebherr excavators, machine operators achieve impressive levels of performance, day-in and day-out. Whether in classic earthmoving, in roadway construction or for digging trenches and laying pipes: more can be achieved faster with Liebherr wheeled excavators.
PAGE 6
Bright and durable • The LED rear lights ﬁtted as standard not only look good, they also have a high brightness level and an extremely long service life. • The LED front outline marker ﬁtted as standard make it easier to see the machine on the road, and thus provides greater safety.
PAGE 7
Reliability Reliability offers safety. Safety that signiﬁcantly inﬂuences the success of a project. Whatever the weather, Liebherr stands for safety - with reliable construction machines and customer-oriented sales and service partners. This means a Liebherr construction machine is exactly what it should be: an investment that pays off.
PAGE 8
Refuelling • Using the optional refuelling pump, the machine can be refuelled directly from a fuel container. • Remote cable operation and automatic shut off when the tank is full, for greater convenience and shorter refuelling times. • Topping up. Simple, quick and safe.
PAGE 9
Comfort The modern Liebherr operator’s cab offers the best preconditions for healthy, concentrated and productive working. The features which make this possible include the standard feature of an air-sprung operator seat with seat heating, the automatic air conditioning and the ergonomically arranged control elements with touch screen indicating unit. One example of the extensive safety equipment is the roll-over protection system (ROPS) for the cab ﬁtted as standard according to ISO 12117-2.
PAGE 10
Low: emissions and operating costs • Compliance with exhaust emission stage IIIB/Tier 4i with efﬁcient Liebherr diesel particle ﬁlter and active regeneration system. • The low-ash Liebherr engine oil, Motoroil 10W-40 low ash, minimises the formation of engine oil ash, and thus extends the cleaning interval for the particle ﬁlter. • Lower emissions. Lower operating costs. Economic environmental protection.
PAGE 11
Efﬁciency Liebherr wheeled excavators are machines that combine high productivity with excellent levels of economy - and all this comes as standard from the factory. On request, the efﬁciency of each wheeled excavator can be boosted further with a Liebherr productive bucket, a fuel-saving Liebherr hydraulic oil or a Liebherr quick coupling system. For more return from each operating hour.
