Yanmar’s Excavator Legacy and the Rise of the VIO Series
Yanmar, founded in 1912 in Osaka, Japan, has long been a pioneer in compact diesel engines and construction machinery. The VIO series—short for “Zero Tail Swing”—was introduced to meet the growing demand for compact excavators that could operate in tight urban spaces without sacrificing performance. The VIO55, a standout in the 5-ton class, offers a blend of maneuverability, hydraulic precision, and operator comfort, making it a favorite among contractors, landscapers, and utility crews.
With an operating weight of approximately 11,850 pounds and a digging depth of over 12 feet, the VIO55 is designed to handle trenching, grading, and light demolition with ease. Its zero tail swing design allows the upper structure to rotate entirely within the track width, reducing the risk of accidental contact in confined areas.
Core Specifications and Performance Highlights
GPS Integration and Control Panel Features
A notable feature in newer VIO55 models is the presence of a GPS module located beneath the right-hand control panel. While not a full telematics system like those found in larger machines, this GPS unit serves several purposes:
Operator Experience and Ergonomic Design
The VIO55 cab is designed with operator comfort in mind. Features include:
Maintenance and Reliability
Yanmar’s reputation for reliability is upheld in the VIO55 through:
The Yanmar VIO55 excavator offers a compelling mix of compact design, hydraulic power, and smart technology. Its GPS integration under the right command panel is more than a novelty—it’s a gateway to modern fleet management and operational efficiency. For contractors seeking a reliable, tech-savvy machine in the 5-ton class, the VIO55 stands out as a forward-thinking choice that blends tradition with innovation.
