4 Ton Mini Excavator
CARTER CT37B - the ideal choice for small and medium-sized engineering scenarios
The 4-ton mini excavator, specially designed for the needs of small and medium-sized projects worldwide, integrates environmental protection and energy conservation, intelligent operation, flexibility and durability. It is widely used in multiple fields such as construction, agricultural development and municipal maintenance. With leading technical configuration and a global service network, it has become a highly trusted engineering partner in the international market.
Golden Power Combination: A perfect balance of strong power and low energy consumption
Equipped with the YANMAR 3TNV88F engine , and adopting electronic fuel injection control technology, the fuel consumption is reduced by 7% compared with similar products, meeting the strict global emission regulations (EU Stage V/US EPA Tier 4 Final).
Intelligent hydraulic system: The AMCA main pump and valve are precisely matched, reducing hydraulic energy loss by 15% and increasing excavation efficiency by 12%, achieving the dual advantages of "strong power and low consumption".
Intelligent constant temperature cabin: Comfortable operation, efficiency doubled
CARTER CT37B compact excavator is equipped with a standard intelligent inverter air conditioning system, supporting temperature adjustment. The cooling and heating modes can quickly reach the set temperature.
Combining the suspended shock-absorbing seat with the ergonomic control console, CT37B excavator is not easy to get tired after long-term operation, allowing every job to be focused and efficient, and providing operators with a comfortable experience like being at home.
Precise application scenarios
Urban and rural municipal engineering: Ideal choice for road maintenance, pipeline laying, ditch excavation and green belt construction.
Small-scale construction and real estate development: Main equipment for villa foundation excavation, community pipeline construction, and site leveling.
Farm and water conservancy construction: Medium-sized ditch excavation, pond dredging, land leveling, and ranch maintenance.
Leasing and contracting services: The "star" model of equipment leasing companies, highly favored for its wide applicability and reliable return rate.
Garden and landscape engineering: Large-scale earthwork modeling and large tree transplanting operations that require certain strength and depth.
