The Vo lvo DD25 small tandem drum roller is an efficient and versatile piece of construction equipment that offers excellent performance and reliability. Here is a detailed introduction:
Basic Specifications
Operating Weight: It has an operating weight of approximately 5,400 lbs (2,450 kg) for the ROPS protection version and 5,725 lbs (2,600 kg) for the cab version, making it easy to transport and operate on various job sites.
Drum Width: The drum width is 39 inches (99 cm) for the ROPS protection version and 47 inches (120 cm) for the cab version, allowing for efficient compaction of different widths of pavements.
Engine: Powered by a Kubota D1803-M three-cylinder diesel engine, it has a rated output of 24.8 kW (33 hp) at 2400 rpm, providing sufficient power to meet the needs of small-scale compaction work.
Performance Characteristics
High-Frequency Compaction: The vibration frequency of the DD25 can be adjusted between 3,300 vpm (55 Hz) and 4,000 vpm (67 Hz), enabling operators to match the frequency to the specific requirements of the job. This high-frequency compaction technology allows for faster travel speeds while maintaining proper impact spacing, resulting in better productivity and a smoother finish.
360° All-Around Visibility: With an ideal seat position and a specially designed engine hood, operators can enjoy a 360° view of the drum edges and the machine's surroundings. This ensures safe and easy operation, whether rolling forward or in reverse, and allows the operator to have a clear view of the work area at all times, improving work efficiency and safety.
Intermittent Water Spray System: The DD25 is equipped with an advanced intermittent water spray system. Operators can precisely control the spraying time of both drums, saving refilling downtime and water usage. The rust-proof, pressurized water system provides a consistent flow of water, preventing asphalt from sticking to the front and rear drum surfaces. The nozzles are equipped with fine filters to maximize spray coverage and minimize the possibility of clogging.
Design and Maintenance
Easy-Access Engine Compartment: The engine compartment of the DD25 is designed for easy access. The hinged engine hood can be tilted forward, allowing operators to easily reach the engine and hydraulic components from the ground for maintenance, inspection, and repair. This design simplifies maintenance work and reduces downtime.
Maintenance-Free Eccentric Bearings: The drums feature maintenance-free eccentric bearings that are sealed and lubricated with lithium grease. These bearings can withstand high operating temperatures and the high rotational speed of the vibration shaft, reducing maintenance costs and improving the reliability of the machine.
Urethane Wipers: The front and rear drums are equipped with long-life urethane wipers, which can effectively remove materials adhered to the drum surface, reducing the frequency of manual cleaning and further improving work efficiency.
Application Areas
The Volvo DD25 small tandem drum roller is ideal for a variety of small-scale compaction projects, including street repairs and patching, parking lots, driveways, and municipal construction. It is suitable for compacting hot mix asphalt, soil sub-base, aggregate base, and other materials, and can complete the work with high quality and efficiency in fewer passes
