More flexible organisation of the construction site with mobile stackersPublished 2/12, 2020 at 14:05
Today modern crushing and screening plants regulate material streams to a large extent automatically.
Nevertheless, machine operators still have a strong influence on the final product quality and the daily output as they coordinate the final products by means of building up stockpiles, intermediate storage areas and loading. With the new ‘Mobibelt’ stackers from Kleemann, logistics can now be organised flexibly and adapted to the respective situation.
The Mobibelt stackers are available in three sizes and designs. The MBT 20 has a crawler chassis and a belt length of 20m, whilst the MBT 24 also offers a further stacker with a crawler chassis and a length of 24m. With a conveyor belt length of 15m, the MBW 15 is the smallest in the portfolio and can be moved with a tractor to any work site. Depending on the construction site, the matching stacker can be used and the logistics can thus be optimised on site.
In order show how the Mobibelt stackers optimise construction site logistics, three examples illustrate the advantages. In example one, the material is loaded by a wheel loader and then cleared away by a mobile stacker. This set up is often used in 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 wheel loader and mobile stacker, only one operator is required and trucks do not need to be loaded directly after the crushing and screening process. This makes a very lean construction site process possible.
The second example is found when 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 pre-screened material has to be discharged, and that no trucks are to be loaded directly downstream of the crushing and screening process, this is the most cost effective variant.
In the third application example, a backhoe excavator loads the material, mobile stackers clear it and a wheel loader loads the processed product. This is one of the most popular variants in recycling and natural stone applications because it makes the highest daily output possible. This process is recommended, in particular, if trucks directly downstream of the crushing and screening process are to be loaded.
