Combined steering for CASE graders

nected from the combined steering, leaving wheel steering angle and frame articulation moving simultaneously. “Precise control of the lean, steering and articulation angles are crucial for maximis- ing efficiencies when operating in restricted areas. But, while operators are concen- trating on manoeuvring the machine, they are spending less time navigating the site effectively and carrying out their grading tasks. This situation can lead to operator fatigue and reduced productivity,” explains Antonio Strati, CASE Road Building product line director. “The unique development is the tem- plate for the next generation of graders. Combined steering automates the optimum position of all three steering components, simplifying the operator tasks, allowing for tighter turns and reducing transit times during non-operating intervals,” adds Strati. Combined steering is a unique technolo- gy that uses a network of angular sensors to provide steering feedback to the vehicle control unit. It can be activated when required and used in conjunction with variable steering ratios to adapt to site conditions. b

Combined steering is a unique technology that uses a network of angular sensors to provide steering feedback to the vehicle control unit.

In an industry first, CASE unveiled patented combined steering functionality in its grader range at bauma 2019. CASE has combined the industry-standard controls for the front wheel and frame articulation angle into one function, managed through either the joystick or the steering wheel.

For those job sites that require tight turns in confined spaces, the two functions can be supplemented by the wheel lean function. At the touch of a button, operators can activate this functionality, making driving and grading tasks much easier. When not required, wheel lean function can be discon-

Comansa adds to its large flat-top tower crane range

Liebherr R 930 and R 926 excavators join Generation 8 series

Comansa announced during bauma 2019 the upcoming addition of another model to its wide range of large flat-top tower cranes. The new 21LC1400 will be available worldwide from September 2019 and will come in two versions, with maximum load capacity of 50 or 66 t. The main expected application of the 21LC1400 is to work in PPVC and infrastructure projects, but the new model will also provide good perfor- mance at sites where it is necessary to lift very heavy loads. Like Comansa’s most recent large models, the 21LC1400 will feature a modular design of the counterjib to highly reduce the counter-radius in constrained jobsites. A new single and compact trolley has also

Liebherr’s R926 crawler excavator was displayed at bauma 2019.

At bauma 2019, Liebherr showcased its R 930 and R 926 crawler excavators. Since the beginning of the year, Liebherr has launched seven crawler excavator models under 50 t. The R 930, the mid-weight model of the series, is a brand new Liebherr crawl- er 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 t: R 922, R 924, R 926, R 930, R 934, R 938 and R 945. The R 930 crawl-

er excavator is fully compatible with the requirements of customers and operators of 30-t machines. The R 926 and the R 930 have an oper- ating weight of between 26 and 36 t, 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. b
