Cat CD44B Combo Compactor Specifications
Compaction Specs
The Cat CD44B Combo Compactor is a highly versatile 7.3-tonne class asphalt roller designed to deliver exceptional compaction performance on Australian roading, commercial, and civil construction projects. Featuring a steel vibratory drum at the front and four pneumatic tyres at the rear, this combination compactor provides the dual benefit of a smooth, dense finish from the drum and the kneading action of the tyres to seal the asphalt surface.
Engineered for high-efficiency operation, the CD44B Combo excels in medium-sized jobs such as highways, urban streets, and car parks. Its advanced steering system, offset drum capabilities, and intuitive operator controls ensure precise handling around kerbs and obstacles, making it a preferred choice for hire fleets and civil contractors across Australia.
