High Efficiency & Specialized Rock Breaking Tech

Hiyo HY300H-S heavy medium excavator stands out among similar 30-ton models for balanced fuel economy and outstanding rock breaking reliability. The optimized large-bore main valve cuts internal pressure loss, while reshaped bucket reduces digging resistance to boost hourly loading output significantly. Independent breaker pipeline and upgraded hydraulic filter system solve common wear issues of hydraulic parts under long-term stone crushing work. The Yuchai power unit provides stable high torque output, matching 217kN bucket digging force to handle thick rock layers and heavy ore piles effortlessly. Users can switch rock and earth buckets freely to adapt different construction tasks without purchasing extra attachments. The 10-inch touch screen and easy-clean air evaporator lower daily machine maintenance workload. With 70% climbing capacity and large digging coverage, HY300H-S is widely used in stone yards, highway roadbeds and large energy construction projects.

Automated Workshop for Hiyo HY300H-S Heavy Excavator

Hiyo builds exclusive standardized workshops for 30-ton heavy excavators with dedicated assembly lines for HY300H-S. The workshop uses robotic thick steel welding and digital hydraulic assembly to strictly control main valve and pipeline assembly precision. Engine and hydraulic core parts are fully inspected before installation to avoid hidden abrasion risks. Each station arranges dedicated QC staff to check welding tightness and hydraulic sealing. After assembly, all machines run 3-hour continuous heavy-load tests to verify digging force and breaking system stability. Clean orderly production lines cut assembly errors, supporting stable mass shipment of HY300H-S to fulfill global highway and energy machinery bulk orders on schedule.
