Product Introductio
Robust Compact Excavator for Heavy-Duty Applications
The NTB45U-C is a powerful mini excavator designed for demanding construction, landscaping, and utility projects requiring substantial digging capability. Weighing 2,600 kg with a 0.06 m³ bucket capacity, this robust machine delivers impressive performance including a maximum digging depth of 2,570 mm, lifting height of 3,453 mm, and unloading height of 2,366 mm. Its extensive 4,250 mm digging radius enables efficient work cycles across large areas. With 30% gradeability and controlled travel speed up to 0.2 km/h, the NTB45U-C maintains stable, precise movement on challenging slopes and confined job sites where accuracy matters most.
Dual Engine Options for Maximum Reliability
Powering the NTB45U-C is a choice of premium Perkins or Yanmar diesel engines, both delivering 18.4 kW maximum output with advanced water-cooling technology for superior thermal management. These renowned powertrains run on standard diesel, providing contractors flexibility and proven reliability. The 16-liter fuel tank pairs with a 20-liter hydraulic oil tank, ensuring balanced fluid capacity for extended operation. This efficient combination minimizes downtime while delivering consistent, responsive power for continuous professional use in construction, agriculture, and municipal maintenance applications worldwide.
Versatile Design with Standard Side Swing
The NTB45U-C features standard 30° side swing functionality, enabling flexible boom positioning for working flush against walls and obstacles without machine repositioning. Compact dimensions—4,181 mm length, 1,500 mm width, and 2,450 mm height—facilitate transport while accommodating a spacious operator station. The 1,500 mm by 200 mm bulldozer blade provides effective grading and backfilling capability. Weighing under 3 tons with optional undercarriage configurations, this excavator bridges the gap between compact maneuverability and serious working power, making the NTB45U-C an ideal solution for contractors seeking versatile, dependable performance.

Applications
Landscaping & Green-space Refurbishment
Slip through 1.2 m gates and edge around prized rose beds without bruising a single blade.
Dig tree pits to exact root-ball depth.
Carve shallow swales and French-drain channels for rain-garden projects.
Peel away tired turf for instant lawn replacement.
Utility & Irrigation Installation
Lay water, gas, fibre or drip lines faster than a pedestrian trencher.
2.4 m dig depth clears the frost line in most regions.
400 mm bucket delivers consistent width for rapid back-fill and compaction.
Side-swing boom runs the trench flush against existing pavement
Indoor & Low-clearance Operations
Rolls through a standard doorway on rubber tracks that leave tile unmarked.
Lower basement floors to gain extra headroom.
Shatter and lift interior slabs with the hydraulic breaker.
Squeezes into 2.3 m parking structures for car-pool lane repairs.
Roadside & Municipal Maintenance
Swap sidewalk panels, grade potholes, bore sign-post holes—done before the signal changes.
Zero tail-swing keeps the machine inside lane cones.
Dual-speed travel (0–4 km/h) paces alongside walking crews.
Canal, Ditch & Environmental Work
Swap in a 600 mm ditching blade or hydraulic rake.
Clear silt from irrigation channels while water flows.
Position rip-rap to check erosion.
Break thin concrete weirs and load spoil direct into a standing truck.
Packaging & Shipping
Our mini excavators ship in professional, export-grade packaging designed for maximum protection and safe global delivery.
Secure Crating
Each unit is bolted to a rugged steel skid and vacuum-sealed in protective film, shielding critical components from dust, moisture and transit impacts—so the machine arrives line-fresh after long-haul journeys.
Container Handling
Fork pockets and integrated ramps let a single operator drive the excavator straight into a 20GP or 40HQ container. Four-corner lashing chains and ISO-rated tensioners lock the undercarriage to the floor, eliminating sway on rough seas or rail hauls.
