CT37B4 Mini Excavator Introduction:
CT37B4 Mini Excavator: This 3.75-ton powerhouse provides heavy-duty performance in cramped areas and was designed for demanding contractors. Its updated YANMAR 3TNV88 engine (20.2 kW, 82.6 N·m torque) offers 10% more power for faster lifting and digging. Operations are smooth and accurate when combined with high-efficiency hydraulics (88 L/min @ 24.5 MPa).
With a maximum dig height of 4.86 meters, a digging depth of 3.11 meters, and a horizontal reach of 5.47 meters, you may do a variety of chores with remarkable reach. Its incredibly small size (1.72 m wide, 860 mm tail swing) allows it to maneuver through confined urban areas with ease, and its low ground pressure (32.0 kPa) protects sensitive 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.
