 Performance Advantages

• Higher digging efficiency: optimized hydraulic pump boosts breaker working efficiency by over 30% for demolition jobs
• Superior trafficability: 58% grade climbing capacity, smooth operation on sloped farmland and uneven construction ground
• Low ground pressure (30kPa), avoids damaging lawn, green plants and brick pavement
• Accurate power matching between engine and main pump, cuts fuel consumption by 12% compared with ordinary mini excavators
• Stable swing performance at 10rpm swing speed, uniform digging depth for pipeline trenching
• Dual travel speed (3/4km/h), fast transfer and slow precise excavation switch freely
• Strong breakout force: bucket digging force 16.6kN, stick force 9.2kN for hard soil and small rock excavation

If you need a versatile mini digger for tight working spaces, Hiyo HY18U zero tail excavator will be your ideal option. Different from ordinary small excavators, HY18U adopts fully retractable track frame, adjusting width between 980mm and 1350mm freely to match different site limits. The 14.6kW Yanmar engine matches Hiyo’s self-developed variable displacement hydraulic pump, raising digging and breaking efficiency without extra fuel waste.

The machine only weighs 1950kg with 30kPa ground pressure, which will not damage lawns, flower beds and paving bricks during landscaping projects. Equipped with suspended adjustable seat and full open maintenance covers, it solves operators’ fatigue and service inconvenience problems. Its zero tail design and offset boom support multi-angle edge excavation, widely applied in municipal pipeline renovation, orchard management, villa courtyard construction and basement finishing. Compared with same-class micro excavators, Hiyo HY18U balances performance, durability and price, becoming a cost-effective work partner for small construction and agricultural users.

Strict Workshop Quality Control for Hiyo Mini Excavators

Every production workshop of Hiyo follows standardized quality management rules for HY18U mini excavators. The welding workshop uses robot welding to form high-strength body frames, avoiding artificial welding defects. Hydraulic assembly workshop carries out pressure test for all hydraulic pipelines to prevent oil leakage during long-time work.

Before leaving the workshop, each HY18U will complete 2-hour full-function trial run, testing digging, swing, traveling and breaking performance comprehensively. Professional inspectors record all data for traceability. Wear-resistant steel plates and imported core components are adopted to extend machine service life. Tight workshop process control reduces failure rate on construction sites, letting end users operate Hiyo HY18U with less maintenance trouble and higher work efficiency.
