MC-92P, MC-92S specifications

The Multiquip MC-92S and MC-92P are high-performance concrete mixers designed for professional use in construction and masonry applications. These models offer a blend of power, durability, and user-friendly features, catering to the demands of contractors and construction workers who require reliable equipment for mixing concrete, mortar, and other materials.

The MC-92S is equipped with a robust 9.0 horsepower Honda gasoline engine that provides ample power for even the most demanding mixing tasks. This model features a 9 cubic feet capacity drum, allowing for larger batches of mixed material. The MC-92S is designed with a heavy-duty steel frame that enhances its durability and stability during operation. The drum is constructed with abrasion-resistant steel, ensuring longevity and minimizing wear over time.

In contrast, the MC-92P utilizes a powerful 9.0-horsepower propane engine, making it an excellent choice for users who prefer cleaner fuel options. This model retains many of the same design features as the MC-92S, including the enhanced drum capacity and rugged frame. The propane engine not only provides a quieter operation but also reduces emissions, making it a more environmentally friendly option without compromising performance.

One of the standout technologies in both models is the innovative mixing mechanism. The unique design of the mixing blades ensures efficient and consistent blending of materials, reducing the time required for mixing and enhancing the quality of the final product. Additionally, the MC-92 series features a manual dump system, which allows operators to easily and accurately discharge mixed material from the drum.

Safety is a primary concern in construction, and Multiquip has incorporated several safety features into these mixers. The control panel is designed for easy access and includes safety switches that prevent accidental start-up. The sturdy base and low center of gravity provide stability during operation, reducing the risk of tipping.

In summary, the Multiquip MC-92S and MC-92P concrete mixers are exceptional tools for professionals needing reliable, efficient, and versatile mixing equipment. With their powerful engines, capacity, durability, and innovative mixing technologies, they stand out in the competitive market of concrete mixers, ensuring that construction projects run smoothly and efficiently.
