As the construction equipment industry heads to Paris for Intermat 2009, ABE reports on the latest new quarry machines that will be launched at the show
Prospects of economic stimulus packages from governments around Europe mean that while general construction is in a slowdown, there are plans for major infrastructure investment. With this will come the demand for aggregates and the need for the latest technology in order to match this demand with large volumes of high quality material.
News of the latest machine launches planned for this year's

Load and haul
Higher productivity and performance are claimed for the new 70 and 80tonne class excavators from
Multimode controls are fitted with a setting that allows speed priority when required and fast cycle times are claimed, along with high digging forces. The CX700B has an operating weight of 68.9tonnes while the CX800B weighs around 80.4tonnes, depending on specification.

According to Keestrack, the system contributes to higher productivity because, through use of presettings, it ensures the machines will automatically start in the correct positions. The company also said that the visualisation of the process by remote wireless technology allows for better checking of onsite processes and quick resolution of problems.
Crushing equipment specialist
The MR100Z can be used in a wide array of applications, including primary crushing of limestone, demolition waste and concrete from demolition projects. The machine has a high crushing capacity while the equipment has a low weight, allowing it to be versatile and easily transportable from site to site. The MR130Z features adjustable rotor speed, while the impact hammer adjustment is said to be easier than on many competing machines. According to the firm, the machine can deliver a high quality product even when processing an irregularly sized feed.
Italian maker
According to KH Mineral CEO Xavier Steiner, although the company's name has changed, the range of static crushers are all still available but the company can now draw from other brands in the Thyssen group to offer complete crushing and screening plants, as well as some semi-mobile units.
Components
According to Michelin, a vehicle equipped with a 23.5 R 25-size tyre, for example, can travel at a speed of 26km/h, which is 18% faster than the model it is replacing. The company have also said that the tyre offers a 10% increase in traction, a new self-cleaning tread with improved longitudinal and transversal grip. The tread is thicker, deeper and more robust than on previous generations of the tyre, which Michelin claims reduces the need for tyre maintenance and offers 10% more service life.
RDS Technology will be displaying a range of cost effective on-board weighing systems. These include the Loadlog 500, designed for small wheeled loaders and skid steers. Easy to use and with improved software for more accurate weighing, the system provides an entry-level to load weighing.
The firm's Loadmaster i range of scales for larger loaders also benefits from improvements in accuracy and consistency. The Loadmaster 8000i now has an integral SD card port for the fast transfer of data between the loader and the office, enabling pre-registered customer data to be uploaded into the weighing system.
Testing
Italian testing equipment manufacturer Controls will show a wide range of equipment at Intermat including its 2000kN Automax 5 50-C4652 compression tester for concrete testing, as well as its range for asphalt testing. The Automax 5 automatic EN models (tested for stability) represent the more sophisticated and advanced evolution of the usual compression testers, according to Controls. The system features the complete automatic test cycle with closed loop digital feedback, and once the specimen parameters have been introduced, it is sufficient to press the 'start' button to complete the test.
Concrete plants
France-based
In a break from Couvrot's use of planetary mixers in mobile units, the new plant features a horizontal mixer - a BHS Sonthofen Twin-shaft mixer. Jeannet said that it is the mixer that gives the unit its 3m3 batching capacity. The 4500 TW has a modular design that allows it to be containerised for transport from site to site with the mixer supplied pre-fitted and cabled to fast track the set up process.
Liebherr will be demonstrating its latest concrete mixing technology at Intermat with the display of the Mobilmix 2.25 R. According to Liebherr, mobile concrete mixing plant is now standard equipment on many major construction projects and the quick setup of its Mobilmix range makes it ideal for this application.
The Mobilmix 2.25 R can be set up in less than two days and has a built-in Liebherr DW 2.25 double-shaft mixer to deliver up to 100m3 of concrete per hour.
Up to 140m3 of aggregates can be stored in the four or six compartments of the inline silo. The compartments are 3.5m wide to make them easier to fill with a wheel loader. The design also features four cement silos, each with a capacity of up to 100tonnes.
Asphalt plants
The Switzerland-based
The plant has a modular construction design based on standardised container dimensions and its transportation is therefore cost-effective.
Higher mobility in high output asphalt production can be achieved with
The plant has been specially designed for the production of new materials with low energy consumption. It features an injector pipe for new binders including foam bitumen, controlled removal of low-temperature gases, anti-condensation system and a retrobatch-type retention system equipped with an electric heater. In addition, the RF400 can also be combined with a TSR high-rate recycling plant for the production of recycled hot mixes at a recycling rate of 70%. RSS
