Description
The hand-guided double-drum vibratory roller, RD7, supplies excellent performance in both soil and asphalt compaction – thanks to the optimally integrated frequency and two vibration stages. As a result, the roller is characterized by its ergonomically arranged operator controls, such as, the engine rpm adjuster attached to the drawbar. Even the easy, tool-free access to all service points makes the RD7 a simple and economical solution for every construction site.
- Easy turning as a result of the long drawbar
- Tight side clearance and more curb freedom for clean working on edges, supported by two scraper bars per drum for a cleaner asphalt surface
- Automatic hydraulic parking brake increases safety, especially when on a slope
- Quickly get ready for transport due to the large tie-down points on all sides and a drawbar locking mechanism automatically operable by foot pedal
- Hand-arm vibrations of less than 2.5 m/s² for more working comfort
Ergonomic guide drawbar
- Ergonomically shaped handle and control lever with grip recesses
- Engine speed adjustment directly on the drawbar
- Two vibration levels for working on different surfaces
- Vibration-damped drawbar for comfortable working (HAV < 2.5 m/s²)
Engine and engine protection for every need
- Various engines to choose from: Honda, Hatz, Yanmar
- Full protection: With steel frame and hood
- Partial protection: With steel frame; hood can be retrofitted
- Without engine protection: steel frame and hood can be retrofitted
Convenient water sprinkling system
- A large water tank (60 l) allows long working intervals without refilling
- Water tank opening offset to the transport lifting eye to avoid damage during transport
- Fill level visible from outside
- Water flow quantity adjustable with lever
Quickly ready for transport
- Automatic drawbar lock in transport position and easy release with foot pedal
- Large lifting eyes on all sides
Easy maintenance
- The engine protection hood can be folded without tools and offers generous access to all maintenance points
- The hydraulic oil level can be read at any time from the outside through a viewing window
- Drums and hydraulic lines can be cleaned easily thanks to robust connections
