Global heavy engineering projects-from open-pit mining and large quarries to bulk construction waste recycling and major infrastructure-are calling for screening attachments that can keep up with high-intensity, high-volume work. For operators using 45–60 ton excavators, finding a reliable, high-capacity screening solution has long been a priority. That's why Motek, a trusted manufacturer of heavy-duty excavator attachments with over a decade of experience, has launched the MTS430-H heavy-duty screening bucket-built specifically to handle the tough demands of large-scale industrial and construction sites worldwide.
Unlike smaller screening buckets made for light-duty tasks, the MTS430-H is engineered from the ground up for heavy loads and continuous operation. It's fully compatible with 45–60 ton excavators-the workhorses of mining, quarrying, and large infrastructure projects-and fits most major global heavy excavator brands. We've kept installation simple with standardized connection dimensions, so operators can mount it on-site quickly without complex modifications. Whether it's dusty open-pit mines, exposed quarry sites, or busy waste recycling yards, the MTS430-H holds up under harsh conditions, maintaining steady performance even during long hours of non-stop work.

At the core of the MTS430-H's performance is its 3 m³ bucket capacity-large enough to handle significant volumes of material per cycle, cutting down on repetitive work and boosting overall project efficiency. Weighing in at 3950 kg, it features a thickened, integrated steel frame that balances structural strength with operational stability-critical for heavy loads, but still flexible enough to maneuver in large work areas. The hydraulic system is industrial-grade, supporting a flow range of 250–450 L/min to deliver the power needed to screen even tough materials: hard quarry rock, mine tailings, river sand and stone mixtures, large construction debris, and industrial slag.
With dimensions of 3150mm × 1502mm × 1695mm, the MTS430-H offers an expanded screening area that improves both throughput and grading accuracy. It sorts materials into consistent, standard sizes-perfect for producing construction-grade aggregates or preparing materials for recycling. Here's where it shines in real-world applications:
Quarries and mining: Grades raw rock into high-quality construction aggregates, reducing the need for additional processing.
Construction waste recycling: Sorts large volumes of demolition debris on-site, turning waste into reusable materials and cutting disposal costs.
Water conservancy projects: Sieves sand and stone from dredged river materials, ideal for reclamation, bank reinforcement, and channel renovation.
Industrial waste treatment: Classifies bulk slag and mine waste for eco-friendly disposal and resource reuse.

Major infrastructure: Screens large quantities of roadbed fillers for highways, bridges, and large municipal projects.
The MTS430-H isn't just built for power-it's built to last. Motek has spent over 10 years refining heavy-duty attachment design, focusing on structural reinforcement, hydraulic matching, and wear-resistant materials. Our core goal is simple: create attachments that are durable, efficient, and easy to maintain, so our global customers can keep their projects on track without frequent downtime.
In production, we stick to strict international heavy machinery standards and the ISO 9001 quality management system. Key parts-including the screening components and stressed areas-are made from high-strength NM400/NM500 wear-resistant steel. Every step, from raw material inspection to precision welding and final testing, is closely monitored to ensure consistency and reliability. We've also integrated mature heavy-load hydraulic technology to reduce blockages and extend the bucket's service life, lowering long-term operating and maintenance costs for our clients.
Motek's standardized production lines and global supply chain mean we can deliver consistent quality on time-critical for large-scale overseas projects where delays can be costly. We've built long-term partnerships with dozens of mining and engineering companies around the world, earning trust through reliable products and responsive after-sales service. The MTS430-H expands our heavy-duty product line, reinforcing our commitment to meeting the needs of the global heavy engineering market.
