The CONSTMACH MOBILE 120 represents a practical solution for construction projects requiring flexibility without compromising output capacity. This mobile concrete batching plant delivers 120 cubic meters per hour through a two-trailer configuration that separates functional components for optimal transport efficiency. One trailer houses the aggregate hopper and weighing system, while the second carries the transfer conveyor and mixing group. This division allows the plant to meet international road transport regulations with dimensions of 14.9 x 3 x 4 meters for the first chassis and 14 x 3 x 3.9 meters for the second, making jobsite relocation straightforward.
What sets the MOBILE 120 apart from conventional mobile plants is its approach to cement storage. Rather than incorporating internal silos that limit capacity and increase transport weight, this model works with external cement silos ranging from 75 to 500 tonnes. This design choice provides genuine scalability for projects with varying cement demands. For operations using bagged cement, the integrated big bag opening and silo charging systems eliminate manual handling bottlenecks, allowing continuous feeding without workflow interruptions.
The mixing heart of the MOBILE 120 is a twin-shaft mixer with 3 cubic meters wet concrete volume. Twin-shaft technology ensures thorough material blending and consistent batch quality, which becomes critical when producing specific concrete grades for infrastructure projects. The mixer's forced mixing action handles even low-slump concrete mixes effectively, something that becomes essential when working with specialized aggregates or additives.
Site preparation requirements have been minimized to a flat surface capable of supporting 58,000 kilograms total weight. There's no need for extensive foundation work or complex installation procedures. This quick setup capability matters when project timelines are tight or when working in remote locations where heavy civil work isn't feasible. The plant requires 500 square meters of operating space and a 300 kVA electric generator to power its 205 kW total motor capacity.
The aggregate handling system uses four hoppers with 25 cubic meters capacity each, feeding into a 4 cubic meter weighing hopper. Material moves through a 1,000 x 14,000 mm weighing conveyor before transferring to the mixer via a 1,000 x 15,000 mm conveyor. For sites where loader access is restricted or ramps aren't practical, aggregate pre-feeding systems can be integrated. These systems eliminate the need for elevated loading ramps, reducing both setup time and site footprint requirements.
Weighing precision directly affects concrete quality, and the MOBILE 120 addresses this with dedicated systems for each material component. Cement weighing operates through an 1,800 kilogram capacity hopper, while water measurement uses a 1,000 liter hopper. Additive dosing is handled by a separate 50 liter hopper, allowing accurate incorporation of plasticizers, accelerators, or other chemical admixtures without cross-contamination risks.
The control system builds on SIEMENS and SCHNEIDER components with PLC-based automation that manages the entire batching sequence. The software interface provides real-time monitoring of material levels, batch cycles, and production statistics. Operators can adjust mix designs, track inventory consumption, and troubleshoot system issues through the control panel without needing external support. Full automatic operation mode reduces operator intervention requirements while maintaining consistent output quality across shifts.
Air system operation runs through a 500 liter compressor with 7.5 kW power, supplying pneumatic controls and cleaning systems. Proper air pressure maintenance ensures valve response times stay consistent and material flow remains uninterrupted during high-volume production periods.
The MOBILE 120 suits contractors working on multiple sites throughout a season, ready-mix producers expanding into new markets, and projects in areas where permanent plants aren't economically justified. Its combination of highway-legal transport dimensions, rapid deployment capability, and genuine production capacity addresses the gap between small portable mixers and stationary batching plants. When project demands shift or contracts complete, the plant moves to the next location without the sunk costs associated with fixed installations.
