MVC-88GH, MVC-88GHW specifications

The Multiquip MVC-88GHW and MVC-88GH are robust and versatile gasoline-powered walk-behind vibratory plate compactors, designed to meet the demands of various construction and landscaping applications. These machines excel in compacting granular soils, crushed aggregate, and asphalt, making them ideal for both commercial and residential projects.

One of the standout features of the MVC-88GHW and MVC-88GH is their powerful 4-stroke Honda GX160 engine. This engine provides reliable performance and outstanding fuel efficiency, significantly reducing downtime and operating costs. With an output of 5.5 horsepower, it delivers ample power to ensure effective soil compaction, enabling users to achieve optimal results on any job site.

Both models boast a rugged, cast iron base plate that offers exceptional stability and durability during operation. The base plates are designed in varying widths, offering versatility to suit different project needs. The MVC-88GHW features a working width of 20 inches, while the MVC-88GH has a slightly narrower width, catering to more confined spaces.

In terms of technology, the MVC-88GHW and MVC-88GH utilize a well-engineered vibratory system that enhances compaction efficiency. The high-frequency vibration, generating up to 5,000 vibrations per minute, ensures deep penetration into the soil, providing maximum compaction in fewer passes. This efficiency not only speeds up the compaction process but also minimizes wear and tear on the machine over time.

Another important characteristic is the operator comfort and safety features included in these models. They are equipped with ergonomic, padded handlebars that reduce operator fatigue, enabling longer working hours without discomfort. Additionally, the machines feature a dead-man throttle for enhanced safety, allowing operators to quickly stop the engine in emergencies.

The MVC-88GHW and MVC-88GH are designed with portability in mind. They are equipped with a transport wheel, making it easy to move them from one job site to another. This feature, coupled with their lightweight design, enhances their usability for contractors and landscapers alike.

In summary, Multiquip's MVC-88GHW and MVC-88GH walk-behind vibratory compactors deliver a perfect blend of power, efficiency, and user convenience, making them essential tools for anyone looking to achieve high-quality compaction results in diverse applications.
