01/19/2016 Flexible high performance: the new mobile concrete mixing plant Mobilmix 2.5 by Liebherr
- Production commences April 2016
- Ready for worldwide projects quickly
- Short cleaning times, low wear and quick assembly times, including for covered plants
The new concrete mixing plant Mobilmix 2.5 by Liebherr offers especially flexible operation, as it is easy to transport and can be set up within two days. This is advantageous for operating at sites with limited concrete production times or other challenging projects. Equipped with a state of the art twin shaft mixer, it is comparable to a stationary mixing plant with regard to performance and comfort.
The unveiling to the public of Liebherr's latest mobile mixing plant Mobilmix 2.5 will take place at the Bauma 2016. Compared to its predecessor version the Mobilmix 2.25, the output capacity has been increased by 10m³ to 110m³ per hour. Liebherr has also optimized a few details. Customers can expect even more efficiency shorter cleaning times, lower wear and quick assembly times, including for covered plants. The basic concept upon which the new Mobilmix 2.5 is built has proven itself over the last 18 years in demanding applications on all continents - over 300 plants of the previous generation were delivered worldwide.
One of the new Mobilmix 2.5 features is a lowered mixer platform. The slight slope to the discharge hopper simplifies cleaning significantly as do the improved spatial conditions and accessibility to the mixer system. A new keyless security system on the mixer access hatch eases access for cleaning work. An innovative feed flap on the skip as well as dust filter systems provide maximum dust protection around the mixer platform. The special design of the skip with parallel designed running surfaces and plastic rollers on the skip ensure comfortable operation with minimum wear and tear. Galvanized assemblies and quality components improve durability.
More or less all building projects such as tunnels, motorways or airport construction require a mobile mixing plant these days. Additionally, ready mix concrete companies also require mobile mixing plants to react to changing market demands in a timely manner. The quick assembly and ease of transporting the Mobilmix 2.5 to different sites predestines this plant for such tasks.
Set up in only two days
The Mobilmix 2.5 plant and in-line silo can be assembled and the electric connected in one day. The basic elements of the new Liebherr mixing plant are positioned on a supporting platform which is transported as a whole on a flatbed truck. The container with the control system is also integrated in this module. The base unit with the mixer system, weighing system and skip is lifted with a crane and unfolded and bolted in working position. The control container offers generous spatial conditions and is equipped with the modern Litronic-MPS micro processor controlsystem by Liebherr. Two additional transportation units provide the in-line silo and the support unit with dosing valves and weighing belt. Up to 140m³ aggregates can be stored in four or six chambers in the in-line silo. The chamber width of 3,50m eases feeding with a wheeled loader.
On the second day, the cement silos are set up and electrically connected. A maximum of six cement silos can be set up, each with up to 120 t capacity.
New twin shaft mixer
The new generation of Liebherr twin shaft mixer has been completely reworked. The Mobilmix uses the new DW 2.5. Many innovations have been integrated into the series for higher customer efficiency. All functional assemblies like electric motors, gears, hydraulics, mixer gate, central lubrication or high pressure cleaning system are placed close together for easy overview. For service work on the mixer, only one of the four sides requires access. Hose and cable paths have been shortened significantly and simplified. The reduction of hoses, corners or edges reduces the cleaning effort. The gears are equipped with a directed oil rinse to stressed bearing points and a radiator which additionally force air from the fan blades into the belt pulley. High operating safety is thereby given even in very hot countries. Changing the wear tiles is now also even easier as all screws are now accessible directly from the outside.
