The new MOBIBELT stackers are available in three sizes. MOBIBELT MBT 20 has a crawler chassis and a belt length of 20 metres. With the MBT 24, Kleemann also offers a further mobile stacker with a crawler chassis and a 24-metre belt length. With a conveyor belt length of 15 metres, the MBW 15 is the smallest in the Wirtgen Group brand’s portfolio and can be moved with a tractor to any work site.
With the new MOBIBELT stackers, Kleemann says quarry and construction site operation logistics can now be organised flexibly and adapted to specific situations. The firm has highlighted three scenarios which are said to demonstrate an optimised logistics process using MOBIBELT stackers.
Application case 1: Operation with wheeled loaders and a mobile stacker
In this example, the material is loaded by a wheeled loader and then cleared away by a mobile stacker. This constellation is often used in different natural stone applications with homogeneous feed material, but it is also suitable for the processing of demolished or cut asphalt.
If work is carried out with a wheeled loader and mobile stacker, only one operator is required, and lorries do not need to be loaded directly after the crushing and screening process. This makes a very lean construction-site process possible.
Application case 2: Operation with an excavator and mobile stacker
In this concrete case, the material is loaded by a backhoe excavator and then cleared away by a mobile stacker. This process can achieve very high daily outputs in recycling and natural stone applications because clearing of the stockpiles is not required.
Provided that no prescreened material has to be discharged and that no lorries are to be loaded directly downstream of the crushing and screening process, this is the most cost-effective variant.
Application case 3: Operation with an excavator, wheeled loader and stacker
In the final application example, a backhoe excavator loads the material, mobile stackers clear it, and a wheeled loader loads the processed product.
This is one of the most popular constellations in recycling and natural stone applications because, in comparison to the other variants, it makes the highest daily output possible. This process is recommended by Kleemann if lorries directly downstream of the crushing and screening process are to be loaded.
