VOLVO DD38HF STATIC SMOOTH DRUM ROLLER

Technical Description

The Volvo DD38HF is a static smooth drum roller designed for efficient and precise compaction of asphalt and granular materials in road construction and maintenance. This tandem drum roller features a compact design with an overall width of approximately 4.8 ft and a drum width of 54.1 in (1,375 mm), making it well-suited for working in confined areas and on narrow pavements. The machine is equipped with a reliable Kubota diesel engine delivering 44 hp of net power, providing sufficient performance for consistent compaction work. It operates at a vibration frequency of 70 Hz (4,200 vpm) with a medium nominal amplitude of 0.1 in and a centrifugal force of 8,093.2 lb, ensuring effective density and smooth finish on various surfaces. The hydrostatic propulsion system powers both drums, enabling excellent traction, a short inside turning radius of 12.8 ft, and strong gradeability. The DD38HF has an operating weight of 8,400 lb (3,810 kg), distributed as 3,925 lb on the front drum and 4,473 lb on the rear drum, contributing to balanced compaction performance. Additional specifications include a fuel capacity of 18 gal, a hydraulic system fluid capacity of 22.4 gal, and a maximum travel speed of 6.3 mph. The machine is equipped with a 12 V electrical system and a 40 A alternator, supporting standard onboard systems and accessories.
