Product Details
The SY75C excavator is engineered as a 7.5-ton versatile compact digging platform designed for high-density excavation, urban utility installation, and quarry auxiliary operations. Built around a stress-tested X-frame chassis and a reinforced boom assembly, this machine delivers a fast total cycle time under 9.0 seconds during continuous trenching loops. Powered by a fuel-efficient 43 kW powertrain coupled with a load-sensing hydraulic main pump, the system dynamically matches pressure and flow based on workload requirements, reducing overall fuel consumption during partial-load operations.

FAQ
Q1: How does the SY75C auxiliary hydraulic line match high-flow attachments like hydraulic breakers or tilting couplers?
A: The SY75C features an integrated proportional dual-way auxiliary line controlled via joystick switches. Main line hydraulic flow delivers up to 149 L/min at 27.5 MPa working pressure. Relief valve pressures can be adjusted to match hydraulic hammer, auger, or shear flow limits without causing system backpressure spike or oil overheating.
Q2: What sea freight packaging and containerization methods are used for bulk SY75C exports?
A: For standard ocean freight, the SY75C fits inside a 40ft High Cube (40HC) container by removing the bucket and adjusting the boom stance. Machine frames are secured via heavy-duty ratchet straps attached to chassis tie-down points. Underbody metal and cylinder rods receive factory-applied anti-corrosion wax spray to protect against saltwater mist during transit.
Q3: How does the engine cooling package perform under 50°C high-ambient desert environments?
A: The SY75C utilizes a heavy-duty side-by-side radiator and hydraulic oil cooler module designed for extreme thermal loads. High-capacity suction fans combined with widened radiator fin spacing prevent dust accumulation while maintaining hydraulic oil working temperatures below 85°C during continuous heavy digging in high-temperature ambient conditions.
