- Kubota V2607: Used by the China excavator SDLG E675F and XCMG XE75DA.
User Feedback & Power: According to user reports, Yanmar engines tend to be slightly noisier. In terms of rated power, the Liugong 9075E leads at 46.3 kW.
3. Excavator Cab Configuration Comparison
The operator’s cab is a critical factor for comfort and productivity. Here’s a comparison of the cab features across the seven models:
1) Space & Size：
Officially, the Liugong CLG9075E, Doosan DX75-9C, and Kobelco SK75-8 are categorized as medium-to-large sized cabs, making them excellent choices for users who prioritize spaciousness.
2) Visibility：
The Sany SY75C and SDLG E675F feature curved glass, which significantly improves rearward visibility for the operator.
3) Interior Features & Ergonomics:
The interior of the Hyundai R75BVS is noted for its simplicity, with relatively fewer user-centric design elements. In contrast, models from Sany, Liugong, Kobelco, XCMG, and SDLG perform better in terms of ergonomic and humanized design.
4) Display：
The Liugong 9075E stands out with a more high-end feel, equipped with a large-sized high-definition display screen.
4. Excavator Comparison by User Reputation & Evaluation
1) Sany 7.5 ton Excavator – SY75C
Pros: Light and effortless controls, very fast cycling speed (both single and combined movements), strong travel power. Isuzu engine is quiet and sounds smooth.
Cons: Cab space is relatively compact. The fuel inlet line lacks a shut-off valve, requiring extra caution during fuel filter changes to manage fuel level.
2) Liugong 7.5 ton Excavator – CLG9075E
Pros: Spacious cab with a luxurious suspension seat and an automatic climate system featuring multiple air vents (including overhead). Energy-efficient with P (High-power) and E (Economy) dual working modes. Ground-level, centralized service points for easy maintenance.
Cons: Cab overhang (6 cm beyond tracks) complicates loading onto trailers and reduces ground clearance.
3) Doosan 7.5 ton Excavator – DX75-9C
Pros: Exceptionally roomy cab. Comfortable suspension seat. Excellent radio reception, even in remote areas.
Cons: Blind spot for the left-side track. Poorly positioned grease fittings make lubrication difficult. Control levers are too thick for comfort. Bucket hinge pin diameter (4.5 cm) is smaller than the common 5 cm standard, raising durability concerns.
4) SDLG 7.5 ton Excavator – E675F
Pros: Good cab space. Fuel consumption is comparable to peers. Kubota engine is quieter than the common Yanmar engines. Operability and power are satisfactory.
Cons: Maintenance costs are reportedly high, exceeding those of some major brands.
5) XCMG 7.5 ton Excavator – XE75DA
Pros: Easy maintenance access (side-mounted pump, large engine bay). Highly comfortable cab (Cat-inspired design, digital display, excellent seat suspension). Powerful A/C cooling.
Cons: A/C is not automatic climate control.
6) Hyundai 7.5 ton Excavator – R75BVS
Pros: Good travel speed. Adequate power when new.
Cons: Poor coordination between travel and implement functions, lacking power for combined movements. Cab feels dated (e.g., mechanical hour meter). Design appears to be a mix of older model components.
7) Kobelco 7.5 ton Excavator – SK75-8
Pros: Highly fuel-efficient Isuzu engine. Large 0.4 m³ bucket offers superior loading and grading efficiency. Well-arranged filters for easy self-service maintenance. Spacious cab with excellent A/C.
Cons: Large bucket can slow down boom lifting, especially when old or in hot conditions. Weak travel power. Lacks track guards and a toolbox. Throttle motor is prone to failure.
