MVC-90H specifications

The Multiquip MVC-90H is a powerful, efficient, and versatile compactor that stands out in the construction and landscaping industries. This machine is designed to tackle various soil types, making it an excellent choice for compacting asphalt, gravel, and other materials in a range of applications.

One of the most notable features of the MVC-90H is its robust Honda engine. This reliable engine delivers unmatched performance, ensuring that the compactor operates at optimal levels even in demanding conditions. The combustion engine not only provides abundant power but also ensures low emissions, aligning with contemporary environmental standards.

The MVC-90H utilizes a unique centrifugal clutch cutting mechanism that allows smooth operation and consistent performance. This technology ensures that the vibratory plate remains in constant contact with the ground, maximizing efficiency during the compaction process. The heavy-duty design of the machine contributes to its durability and reliability on job sites, ensuring it can withstand the rigors of everyday use.

Another significant characteristic of the MVC-90H is its user-friendly design. It features adjustable handles that can be set to various heights to accommodate operators of different sizes, providing comfort and reducing operator fatigue. Additionally, the compactor’s compact size and lightweight construction make it easy to transport to and from job sites without the need for heavy-duty equipment.

The machine is also equipped with a high-frequency vibration system that enhances the effectiveness of compaction. This high-frequency technology allows for better penetration of soil, resulting in a denser and more stable ground. It is particularly useful in areas where precision in compaction is critical, such as in trench backfilling or base preparation for paving.

Furthermore, the MVC-90H is designed with an integrated water tank system that helps prevent asphalt from sticking to the plate during operation. This feature increases operational efficiency and reduces downtime, allowing operators to complete their tasks more swiftly.

In summary, the Multiquip MVC-90H is a well-rounded compactor that combines powerful performance with user-friendly features. Its robust Honda engine, advanced compaction technologies, and practical design make it an ideal choice for professionals seeking reliability, efficiency, and ease of use on their projects. Whether for commercial construction or landscaping tasks, the MVC-90H proves to be a valuable asset in any contractor's toolkit.
