Product Details:
Simply Powerful With a sturdy 3.75 ton frame and 0.12m³ bucket capacity, the CT37B Mini Excavator is ideal for medium sized projects that require both strength and mobility. CT37B Mini Excavator handles even the most difficult to compact materials with ease, thanks to a premium YANMAR 3TNV88F water-cooled diesel engine (18.2 kW) and an extremely efficient hydraulic system (88 L/min flow; 24.5 MPa pressure)—which offer higher cycle times. Boasting dimensions such as a maximum digging height of 4.86 m, depth of 3.11m and reach of 5.47 m, this mini excavator is the capable machine when it comes to deep dig and high reach work requirements. Its 860 mm tail swing radius and 1.72 m width allow easy movement through tight urban areas, while 32.0 kPa of ground pressure protect fragile surfaces.
Features like dual-speed travel (2.2/4.2 km/h), a rugged undercarriage (58% climbing grade), and an integrated dozer blade (300 mm height) make the CT37B ideal for construction, utilities, and landscaping—where power, precision, and space efficiency collide.

CT37B Mini Excavator Feature
1. Compact and Flexible for Confined Spaces
In addition, with an overall width of 1.72 m and tail swing radius of just 860 mm the excavator can be used productively in confined spaces such as urban job sites, basements or indoors. A ground pressure of only 32.0 kPa prevents damage to the working area such as lawns or farmland and enables machine operation on sensitive surfaces with a tiling task in gardens or landscaping. Furthermore, the transport length of 4.92 meters is easy to handle - it can be transported on common flatbed trucks.
2. Efficient Power and Fuel Economy
The 3TNV88F YANMAR engine on the CT37B generates 82.6 N·m of torque at just 1,320 rpm to further maximise fuel economy whether trenching or material loading in heavy duty applications. The engine innovative low-emission structure should meet more stringent emissions requirements (such as China National III/Euro III+) with less pollutants. The hydraulics deliver 24.5 MPa working pressure and an 88 L/min flow rate for fast response time and excellent digging force (30.4 kN bucket force) whether your job is to excavate or crush rock.
3. Versatility Across Challenging Terrains
With a 58% climbing capability and 295 mm ground clearance, this excavator excels on slopes, rocky surfaces, or uneven terrain. Its integrated dozer blade (375 mm lifting height and 370 mm digging depth) enables quick ground leveling, reducing the need for additional equipment. Dual travel speeds (up to 4.2 km/h) further enhance mobility across worksites.
4. Professional-Grade Excavation Performance
The CT37B offers a maximum digging depth of 3.1 meters for pipeline or foundation work and a vertical wall digging depth of 2.7 meters for projects like retaining walls. Its 4.85-meter maximum digging height supports tasks like material dumping or tree trimming. Optional arm lengths (1.4 m or 1.65 m) provide flexibility for power-focused or extended-reach operations.
5. Safety and Operator-Centric Design
The tight tail swing radius (860 mm) reduces collision risks in confined areas. The reinforced cab (2.55 m height) likely includes ROPS certification for operator protection. With a 50-liter fuel tank and 40-liter hydraulic tank, the machine supports extended operation with minimal downtime.
