market, Liebherr used Bauma 2016 earlier this year to showcase its complete renewal programme of all crawler excavator models for developing markets between 20 and 25 t. This included the 22 t R 922, the 21 t R 920 and the 24 t R 924. The jewel in the crown for this range is the R 922 crawler excavator. “The concept of the Liebherr R 922 is based on European standards and aims to improve reliability, increase productivity and lower fuel con- sumption,” says Tendayi Kudumba, divisional manager of Earthmoving Technology (EMT) at Liebherr Africa. “The launch of the R 922 is accompanied by a complete regeneration of all crawler excavator models for developing markets between 20 t and 25t.” The R 922 replaces the R 916. Compared with its predecessor, the biggest change to the R 922 is a shift from the Liebherr engine to a six-cylinder Cummins Tier III motor said to significantly lower the price of the ma- chine. The Cummins engine also comes with an automatic fuel-saving idling system for greater fuel savings. This is complemented by its “Wastegate” turbo for enhanced per- formance at low speed and reduced fuel con- sumption. The electronic power control system allows the engine to be effectively and optimally converted, from an energy point of view, into hydraulic power. “This trans- lates into greater forces, faster working speeds and lower fuel consumption,” says Kudumba. Another key feature is the positive con- trol hydraulic system. Two working pumps for maximum excavation, travel or swing, provide power to the components involved. Thanks to the positive control system, the combined movements are optimised for each different work operation, whether it

parameters transmitted has been increased from 12 to 40, enabling the fleet manager to monitor a comprehensive range of health and performance indicators of his equip- ment. “This makes it easier to maximise the fleet’s productivity and utilisation, as well as preventing potential issues and ensure every machine’s optimum health,” says Strati. CASE has also recently introduced the upgraded user interface of its SiteWatch telematics portal. The portal has been redesigned using HTML5 and the latest web development technologies. This de- velopment means easier and faster navi- gation. The navigation approach has been revised; the simpler structure and use of drop-down menus enables the user to find and access the desired information more easily and faster. Fleet management has also been made easier. A full-screen map shows the location of all deployed machines. To visualise the information about a specific unit, the fleet manager just needs to click on the machine and a pop-up box will appear with all the de- tails. In addition, a floating panel on the map shows the set geofences, making it easy to update them as needed. SiteWatch also now offers a maintenance forecasting functionality – said to be a first in the market. “This new feature calculates the date when the next service is due based on the daily usage of the vehicle, rather than just indicate how many hours of work are left before the maintenance interval ends. This makes it even easier to plan for each unit’s maintenance and optimise the deployment of the fleet,” says Strati. Digging Korean efficiency HPE Africa, the exclusive distributor for Hyundai earthmoving equipment in South

Africa, has launched the new Hyundai Robex R180LC-9S excavator to the local market, said to offer greater fuel efficiency. “This high power machine has been engineered for optimum performance, precision control and enhanced operator safety. This model boasts greater fuel efficiency in the 20 t class – an increasingly important feature as fuel prices continue to rise,” says Alex Ackron, managing director of HPE Africa, part of the Capital Equipment Group (CEG) of Invicta Holdings Limited. “The R180 series, which is fitted with a specially manufactured bucket for the local market, has an operating weight of 19,1 t. The Hyundai Robex R180LC-9S excavator is partic- ularly suited for plant hire, civil engineering, construction and agriculture,” adds Ackron. A computer aided power optimisation (CAPO) system ensures the optimum level of engine power and hydraulic flow. The CAPO system also provides complete diagnostic features and digital gauges for critical infor- mation such as fuel levels, hydraulic oil and water temperatures. The machine comes with three variable operating modes. These are: P – Power Max, which maximises machine speed and power; S–Standard mode, said to provide a reduced, fixed rpm for maximum fuel savings and im- proved control; and E – Economy mode which provides precise flow and power based on load demand. The machine has ground-line access to all critical service and grease points. The com- pact size of the engine allows for easy main- tenance and the low engine height, with a side-mounted, gear-drive camshaft, ensures easy access.
