Hiyo HY125C Medium Crawler Excavator

If you need a balanced medium excavator for mixed earthmoving and trenching jobs, Hiyo HY125C will be your most cost-effective choice. Different from light 6-ton diggers, this 12.5t model owns bigger bucket, stronger traction and heavy-duty digging power, ideal for large foundation, long drainage ditch and urban pipeline laying works.

Cummins power unit perfectly matches self-developed positive flow hydraulic circuit, lifting working efficiency without excessive fuel waste. Reinforced robot-welded boom and arm extend service life greatly. The centralized side maintenance cover allows filter & oil replacement within 20 minutes to save maintenance labor. Moderate 41.6kPa ground pressure protects city roads and green belts. Compatible with breaker and grab attachments, it covers most medium construction scenarios, bringing stable profit for construction business owners.

Key Highlight Features
