CT37BH Mini Excavator Introduction:
The CT37BH Mini Excavator redefines heavy-duty efficiency in compact spaces, offering 3.75 tons of robust performance paired with unmatched agility. Powered by the YANMAR 3TNV88F engine (18.2 kW, 82.6 N·m torque), it tackles tough excavation and lifting tasks effortlessly, supported by a high-efficiency hydraulic system (88 L/min flow, 24.5 MPa pressure) for rapid cycle times. With a 4.86 m max digging height, 3.11 m digging depth, and 5.47 m reach, it masters deep trenches, high-reach demolition, and precision landscaping. Its ultra-compact 860 mm tail swing radius and 1.72 m width navigate tight urban job sites with ease, while 32.0 kPa ground pressure minimizes terrain impact. Dual-speed travel (2.2/4.2 km/h), a rugged undercarriage (58% climbing grade), and an integrated dozer blade (300 mm height) ensure stability and versatility across slopes, rough terrain, and confined spaces. Designed for operators, the ROPS/FOPS-certified cab prioritizes comfort and visibility, making the CT37BH the ultimate choice for construction, utilities, and agriculture—where power meets precision in every dig.
