As large-area river dredging, highway subgrade reinforcement and industrial-site contaminated soil remediation projects grow year by year, global contractors are in urgent need of medium-to-heavy mixing attachments with deeper penetration and higher processing capacity. To fill the market gap between mid-size light mixers and oversized heavy-duty mixing equipment, MOTEK Construction Machinery has officially unveiled its brand-new MT250 hydraulic soil power mixer, optimized exclusively for 24–30 ton excavators. Balancing extended working depth, boosted mixing throughput and flexible cross-site mobility, the new model also comes with a full localized spare parts supply scheme to cut downtime during peak construction seasons.
Developed to match mid-heavy excavator fleets widely adopted by civil and environmental contractors, the MT250 features an integrated compact frame with fixed outer dimensions of 5700mm × 1500mm × 1000mm and a self-weight of 2,150kg. Its streamlined frame design removes redundant protruding components, enabling straightforward full-container loading for long-distance transit between large river dredging zones, industrial remediation plots and suburban road construction sites. Fitted with a universal quick hitch interface, the attachment requires no structural refitting on compatible excavators after fast connection, retaining the host machine's maneuverability even on uneven rural construction grounds and wide municipal foundation trenches. The unit supports a maximum mixing depth of 5 meters, easily covering deep-layer soft ground solidification, deep river silt stabilization and thick backfill treatment work. It effectively avoids the shallow working limitation of smaller mixing heads and eliminates excessive fuel consumption brought by oversize heavy-duty mixers on medium-scale projects.
Superior hydraulic matching and flexible speed adjustment form the core competitive advantage of the MT250 series. All hydraulic parameters are precisely calibrated to fit the oil delivery performance of 24–30 ton excavators, supporting a hydraulic flow range of 180–250 L/min with a maximum working pressure of 34.5MPa. Its adjustable rotation speed covers 50–100 r/min, allowing operators to switch working modes freely based on on-site material conditions. The low-speed high-torque mode handles dense silt mixed with gravel and hard clay layers, while the high-speed uniform stirring mode delivers consistent blending for bulk loose soil mixed with curing agents. Equipped with an upgraded widened double spiral mixing drum and thickened alloy stirring blades, the mixer eliminates dead mixing zones completely and achieves steady hourly output of 40–60 cubic meters. This higher continuous efficiency shortens construction cycles drastically for large batches of foundation reinforcement and river dredging treatment projects, solving the common industry headache of low productivity caused by mismatched hydraulic power between mixing heads and mid-heavy excavators.
All load-bearing structural parts and core stirring components of the MT250 adopt one-piece forging plus surface quenching treatment with high-chromium wear-resistant alloy steel, drastically lifting resistance against abrasion and heavy impact when processing high-moisture sludge, sticky clay and mixed construction residual soil. Compared with ultra-heavy large mixing attachments that bring extra load to excavator arms and raise daily fuel costs, the 2,150kg moderate self-weight reduces unnecessary arm load and lowers long-term operation expenditure for contractors. In terms of environmental compliance, the sealed dustproof outer shell and low-noise integrated hydraulic valve block suppress construction dust and running noise effectively, fully satisfying emission limits for residential surrounding areas, ecological river corridors and farmland restoration zones. All treated silt and soft subsoil can be reused as on-site backfill material, slashing waste transportation volumes and supporting low-carbon circular construction workflows.
The MT250 integrates an intelligent adaptive hydraulic matching system, which automatically distributes hydraulic flow and pressure in real time according to underground soil hardness. This design guarantees even fusion of raw soil, curing agents and auxiliary admixtures without secondary manual re-stirring after mixing. The standard universal quick coupler is compatible with all mainstream 24–30 ton excavator brands globally, supporting seamless switching between deep river dredging, large-area foundation reinforcement, farmland soil improvement and municipal pipeline backfilling tasks. For engineering firms undertaking multiple scattered medium-to-large projects simultaneously, the MT250 removes the necessity to rent multiple dedicated ground improvement machines, cutting overall expenses on equipment procurement, cross-site transportation and storage at a single stroke.
MOTEK has built a complete product matrix covering light, medium and medium-heavy soil mixing attachments to meet differentiated project scale demands worldwide. The rollout of MT250 completes the brand's medium-heavy mixing equipment lineup, specially targeting contractors focusing on large river dredging, suburban highway infrastructure and extensive industrial contaminated site remediation. Moving forward, MOTEK will keep optimizing segmented hydraulic attachment solutions based on real-site construction feedback from global partners, upgrading high-output, deep-working lightweight product lines and expanding regional spare parts stock and on-site rapid maintenance services. The brand aims to help global construction operators achieve higher return on investment with energy-saving, multi-scenario deep ground improvement attachments.
