The Sany SY375H is a 37-ton hydraulic excavator introduced in 2020, widely recognized for its reliability in heavy-duty construction projects. Produced by Sany Heavy Industry, a leading Chinese construction equipment manufacturer established in 1989, the SY375H has contributed to Sany’s global growth, which includes over 200,000 units sold worldwide. Its robust design combines traditional power systems with advanced hydraulic technology, ensuring both efficiency and durability.
Engine and Power System
The SY375H is powered by the GH-6HK1XKSC engine, a 6-cylinder, 4-stroke, water-cooled diesel engine with direct injection and turbocharged intercooling. It delivers 212 kW at 2000 rpm, with a maximum torque of 1080 N·m at 1500 rpm. The 7.79-liter displacement ensures high efficiency for large-scale earthmoving, while the turbocharged and intercooler system enhances fuel economy under heavy loads.
Performance Specifications
The excavator offers a bucket digging force of 235 kN and an arm digging force of 210 kN, making it suitable for both hard and soft soil operations. It has a slope capability of 70%, a travel speed of 5.5/3.5 km/h, and a ground pressure of 68.8 kPa. Its 8.8 rpm swing speed ensures smooth rotation for precise positioning, critical for trenching and foundation work.
Hydraulic System and Capacities
The SY375H uses a conventional hydraulic system, providing reliable operation for heavy-duty tasks. The fuel tank holds 540 liters, and engine oil replacement requires 36 liters. Hydraulic oil is optimized for both lifting and digging functions, with the cylinders sized to provide stability and high efficiency.

The SY375H excels in large construction, mining, and infrastructure projects due to its high bucket capacity and strong digging force. Operators benefit from its balanced stability and powerful hydraulic system. Companies often report reduced cycle times and increased productivity when using this model for foundation excavation, road construction, and heavy trenching. Its fuel efficiency and engine durability also minimize long-term operational costs.
Maintenance and Recommendations
Regular inspection of hydraulic hoses, track tension, and engine oil levels is crucial for maximizing service life. Using recommended Sany hydraulic fluids and keeping the cooling system clean ensures consistent performance in high-temperature environments. Operators should schedule 500-hour maintenance checks, including filter replacement, lubrication, and torque checks on all pins and joints.
