CT37BH Mini Excavator Introduction:
CT37B4 Mini Excavator: Designed for demanding contractors, this 3.75-ton powerhouse offers heavy-duty performance in confined spaces. For quicker lifting and excavation, the upgraded YANMAR 3TNV88 engine (20.2 kW, 82.6 N·m torque) provides 10% more power. When paired with high-efficiency hydraulics (88 L/min at 24.5 MPa), operations are precise and seamless.
You may do a range of tasks with exceptional reach thanks to its maximum dig height of 4.86 meters, digging depth of 3.11 meters, and horizontal reach of 5.47 meters. It can easily go through tight urban spaces thanks to its minuscule size (1.72 m width, 860 mm tail swing), and its low ground pressure (32.0 kPa) shields delicate surfaces.Dual-speed travel (2.2/4.2 km/h), a sturdy undercarriage (58% gradeability), and an integrated dozer blade (300 mm height) all contribute to increased versatility. The CT37B4 is the perfect combination of raw power, accuracy, and space efficiency, and it shines in construction, utilities, and landscaping.
