The HAMM HW 90 B 12-MT is a smooth drum roller designed for efficient compaction. It features a drum width of 43.3 inches and an operating width matching this dimension, providing optimal surface coverage for smooth compaction tasks. The roller employs a static 3-wheel vibration system, ensuring even pressure distribution without vibratory action, ideal for specific soil and asphalt applications requiring static compaction. It boasts a tight inside turning radius of 93 inches, enhancing maneuverability on confined job sites. Powered by a reliable Deutz engine, the HW 90 B 12-MT delivers steady performance consistent with the robust demands of construction environments. The machine’s weight is approximately 12.6 metric tons, contributing to its compaction force and operational stability. Its compact transport dimensions of around 4.89 m length, 2.66 m width, and 3.22 m height facilitate ease of transport and setup. The hydraulic hydrostatic drive system offers smooth speed control and responsive handling. Operator comfort is addressed with ergonomic seating and controls. The HW 90 B 12-MT delivers an ideal load distribution between the front and rear drums, enhancing compaction effectiveness. Its design supports a turning radius optimized for urban and restricted-space operation, while the static drum system makes it suitable for layered or sensitive compaction tasks. Overall, the HAMM HW 90 B 12-MT offers a balance of power, precision, and durability tailored for professional compaction in roadway, foundation, and utility construction projects.
