As regional infrastructure upgrades and soil remediation work keep expanding across Europe, Southeast Asia and other global markets, a large share of ground improvement jobs rely on 20–25 ton excavators - the most popular machine class for rental firms and small-to-mid-sized contractors. Operators are frequently faced with a clear trade-off: compact mixing tools lack sufficient depth for road subgrade and river silt treatment, while larger mixing attachments overload 25-tonne carriers, raising fuel consumption and limiting mobility on tight urban sites. To fill this gap in the mid-light equipment segment, MOTEK Construction Machinery unveils the brand-new MTM200 hydraulic soil mixer, purpose-built for 20–25 ton excavators, balancing compact outer dimensions, stable hydraulic performance and consistent field productivity.
Developed to pair directly with mainstream 20–25 ton excavator models widely used in municipal works and environmental projects, the MTM200 adopts a robust integrated welded frame. Its overall dimension stands at 4200mm × 1500mm × 1000mm, with an operating weight of 1970 kg. The streamlined outline avoids protruding structures, making the attachment easy to load into standard shipping containers for cross-region transport. It suits frequently relocated projects: urban road foundation stabilisation, channel silt solidification, pipeline backfill treatment and small-scale contaminated land remediation. Fitted with a universal quick hitch interface, the mixing head can be mounted and put into operation quickly without major machine modification. The maximum stirring depth reaches 3.5 metres, perfectly covering most shallow-to-medium depth ground improvement tasks. It eliminates two common frustrations for contractors: inadequate working depth from mini mixers, and unnecessary weight and power waste brought by oversized mixing equipment.
Well-calibrated hydraulic configuration forms the core strength of the MTM200 soil mixer. Tuned specifically to match the oil supply characteristics of 20–25 ton excavators, the unit supports a maximum working pressure of 34.5MPa, operating hydraulic flow ranging from 150 L/min to 220 L/min, and adjustable rotation speed between 50–90 r/min. Operators can adjust rotational speed flexibly to adapt to variable ground conditions on site. Low-speed high-torque output works best for stiff clay, silt mixed with gravel, delivering strong cutting and uniform blending capacity. Higher rotation speeds are ideal for mixing loose soil together with curing agents to achieve even solidification. The upgraded multi-spiral stirring assembly minimises dead zones inside the mixing zone, sustaining steady working output of 35–50 cubic metres per hour. This reliable efficiency helps contractors shorten overall project schedules and addresses the widespread issue of mismatched power output seen on many generic mid-light mixing attachments available today.
Critical load-bearing components and stirring blades on the MTM200 are manufactured from surface-quenched high-chromium wear-resistant alloy steel, with integral forging applied to key stressed parts. This design greatly enhances wear and impact resistance when processing sticky sludge, wet clay and mixed construction spoil. Weighing only 1970 kg, the unit imposes a reasonable load on the excavator arm. Compared with heavier mixing alternatives, it reduces long-term fuel costs and lowers fatigue wear on the carrier machine. A fully sealed dustproof housing and optimised low-noise hydraulic manifold are equipped as standard, restricting dust emission and operational noise. This enables construction activities near residential districts, riverside ecological zones and environmentally sensitive remediation sites, complying with strict local environmental control requirements. Treated silt and soft soil after in-situ mixing can be reused as backfill material, cutting haulage fees for waste soil and supporting sustainable, low-carbon construction methods.
The adaptive hydraulic control system fitted on MTM200 dynamically allocates pressure and flow according to real-time soil resistance underground. It guarantees thorough mixing of native soil, curing agents and additives, reducing the need for extra manual levelling after stirring. Thanks to its universal quick coupler design, the mixing head can be fitted on nearly all mainstream 20–25 ton excavator brands. A single attachment can switch freely among foundation reinforcement, river silt treatment, contaminated soil restoration and municipal backfilling assignments. For contractors managing multiple distributed small and medium projects, the MTM200 consolidates multiple construction capabilities within one attachment, lowering combined spending on equipment purchase, logistics and storage.
MOTEK continues to advance differentiated development for excavator hydraulic attachments, building a full-spectrum product lineup that covers light, medium and heavy-duty mixing heads, screening buckets and crusher buckets, to satisfy varied project demands worldwide. The rollout of MTM200 completes the brand's offering for mid-light soil treatment attachments, catering specifically to rental businesses and regional contractors focusing on municipal construction, environmental dredging and land rehabilitation. Going forward, MOTEK will keep refining product performance based on feedback collected from construction sites globally, launching more energy-efficient, durable attachments. The brand will also push forward regional spare parts stocking and responsive after-sales service, helping engineering customers around the world achieve better return on investment with versatile, dependable ground improvement attachments.
