Against the continuous expansion of global environmental governance and urban infrastructure construction, medium-depth foundation reinforcement, river silt solidification and contaminated site remediation projects have seen sustained growth. Many engineering contractors struggle with two common dilemmas: lightweight mixing heads cannot reach enough working depth for mid-scale foundation treatment, while large heavy-duty mixing equipment is overly bulky and brings extra fuel consumption and mobility troubles for 24–30 ton mainstream excavators. To fill this market gap, MOTEK Construction Machinery has officially launched its new MTM250 hydraulic soil power mixer, precisely customized for 24–30 ton excavator hosts, balancing moderate body size, stable hydraulic performance and high continuous construction efficiency.
Tailored exclusively for 24–30 ton excavators widely used in global engineering rental and construction teams, the MTM250 adopts an integrated reinforced frame structure, with fixed overall outer dimensions of 5700mm × 1500mm × 1000mm and a total operating weight of 2150 kilograms. The streamlined integrated layout abandons redundant protruding structures, making the equipment fully compatible with standard container transportation, and enabling quick transfers between scattered construction sites including urban municipal trenches, river dredging sections, suburban road foundation projects and polluted soil remediation yards. Supported by standard quick hitch connectors, the mixing head can finish installation and debugging within minutes without extra refitting to matched excavators, well preserving the host machine's flexibility in narrow and complex construction environments. The equipment supports a maximum stirring depth of 5 meters, which perfectly covers the depth requirement of most medium-depth soft foundation stabilization, pipeline backfilling consolidation and river silt disposal projects, avoiding energy waste caused by excessive configuration of ultra-large mixing equipment while solving the shallow-depth limitation of small-sized mixing heads.
Hydraulic matching and adjustable power output stand as the core competitive advantages of the MTM250 mixing head. After precise hydraulic calibration targeting 24–30 ton excavator oil supply parameters, the equipment bears a maximum working pressure up to 34.5MPa, with an adaptable hydraulic flow range of 180–250 L/min and adjustable rotational speed from 50 r/min to 100 r/min. Construction operators can flexibly switch operating modes according to on-site soil conditions: low-speed high-torque mode is available for dense silt mixed with gravel and hard clay, delivering powerful cutting and uniform stirring force; high-speed rotation mode suits loose soil mixed with curing agents, achieving rapid and even material fusion. The optimized multi-group spiral stirring structure eliminates internal stirring blind spots thoroughly, locking a stable hourly working efficiency between 40 cubic meters and 60 cubic meters. This steady and efficient output greatly shortens the construction cycle of batch foundation treatment projects, fundamentally improving the mismatched power and low-efficiency pain point widely existing in mid-tonnage mixing equipment on the market.
All key load-bearing components and stirring blades of MTM250 are forged integrally and treated with surface quenching high chromium wear-resistant alloy steel, significantly lifting abrasion resistance and impact resistance when coping with high-moisture sludge, sticky clay and mixed construction residue soil. Compared with overweight heavy-duty mixing heads, its moderate 2150kg weight will not bring excessive load to the excavator arm, effectively reducing long-term fuel expenditure for contractors. The equipment is equipped with fully sealed dust-proof shell and low-noise hydraulic valve block, which effectively suppresses construction dust and running noise, fully complying with environmental construction standards in residential areas, ecological river banks and sensitive remediation zones. After on-site stirring and solidification, silt and soft soil can be directly reused as backfill aggregate, cutting waste transportation costs and supporting low-carbon, circular green construction modes.
The built-in adaptive hydraulic regulation system of MTM250 can automatically distribute pressure and flow in real time according to underground soil hardness, ensuring full homogeneous mixing of raw soil, curing agents and additives without secondary manual finishing. Its universal quick coupler matches all mainstream brands of 24–30 ton excavators on the market, allowing a single device to freely switch between foundation reinforcement, river dredging treatment, industrial contaminated soil remediation and municipal backfilling operations. For engineering companies undertaking multi-site scattered orders, MTM250 integrates multiple construction functions into one attachment, cutting comprehensive expenditure on equipment procurement, transportation and storage.
MOTEK has long insisted on differentiated R&D and classified iteration of excavator hydraulic attachments, gradually building a complete product matrix covering light, medium and heavy mixing heads, screening buckets and crusher buckets to satisfy construction demands of different project scales worldwide. The release of MTM250 further improves the brand's medium-tonnage soil treatment equipment layout, focusing on serving regional contractors engaged in municipal infrastructure, environmental dredging and land consolidation projects. In the next stage, MOTEK will keep optimizing product performance based on global on-site construction feedback, continuously iterate high-efficiency, low-consumption attachments, and advance localized spare parts stocking and rapid after-sales maintenance services, helping global engineering customers obtain higher investment returns with reliable, multi-scenario ground improvement equipment.
