Compact Excavator Showdown IHI Komatsu Yanmar Compared

As urban construction and landscaping projects increasingly demand equipment that can operate in confined areas, manufacturers are developing compact excavators with multifunctional capabilities. The latest generation of 0.12-cubic-meter backhoe-loader hybrids combines space-efficient designs with robust performance, offering innovative solutions for municipal infrastructure and green space development. This analysis compares three representative models from IHI, Komatsu (KOBELCO), and Yanmar, examining their dimensional specifications, operational parameters, and unique features to assist potential buyers in making informed decisions.

The evaluated machines include IHI's 30VX, Komatsu's SK30SR, and Yanmar's VIO30—all belonging to the 0.12-cubic-meter class of enhanced-lift backhoe excavators. While maintaining nearly identical transport-friendly dimensions suitable for urban environments, each model presents subtle variations in configuration:

• IHI 30VX: Length 4370mm, width 1550mm, height 2470mm, operating weight 2300kg
• Komatsu SK30SR: Length 4470mm, width 1550mm, height 2570mm, operating weight 2450kg
• Yanmar VIO30: Length 4450mm, width 1550mm, height 2510mm, operating weight 2340kg

A detailed comparison reveals specialized strengths in digging parameters:

The IHI model leads in working height and reach, Komatsu offers superior floor-level excavation radius (4930mm), while Yanmar demonstrates exceptional depth capabilities—particularly in vertical digging scenarios.

The dual-purpose nature of these machines makes lifting specifications particularly crucial:

• IHI 30VX: 0.6-ton max capacity (0.6t×2400mm to 0.22t×4200mm working range)
• Komatsu SK30SR: 0.71-ton max capacity (0.71t×1800mm to 0.18t×4200mm working range)
• Yanmar VIO30: 0.9-ton max capacity (0.9t×1900mm to 0.2t×4200mm working range)

All three models utilize Yanmar diesel engines with varying configurations:

• IHI 30VX: 3TNV84 (24.2HP @2200rpm)
• Komatsu SK30SR: EDM-3TNV88 (21.2HP @2400rpm)
• Yanmar VIO30: 3TNV82A-NBV2 (24.6HP @2500rpm)

Each powerplant delivers fuel efficiency and low emissions while meeting current environmental regulations.

Manufacturer-specific enhancements include:

• IHI: Optimized hydraulic system for smoother operation
• Komatsu: Enhanced cabin comfort reducing operator fatigue
• Yanmar: Zero-tail-swing design for confined space safety

Standard equipment across all models includes dozer blades and rubber tracks for improved stability and surface protection.

For projects prioritizing reach and height clearance, the IHI 30VX proves most capable. The Komatsu SK30SR excels in extended floor-level operations, while Yanmar's VIO30 dominates in deep excavation and heavy lifting scenarios. This comparative analysis provides objective benchmarks to inform equipment acquisition decisions.
