WS205HD-3 single drum roller compactor is primarily suitable for compacting base layers, sub-base layers, and fills of various materials. It is an ideal compaction equipment for high-grade highways, airports, ports, dams, and industrial construction sites.
Main Technical Performance Characteristics
01. Powerful Engine
The WS205HD-3 single drum road vibratory roller is equipped with a Weichai Stage III engine with a power of 147 kW. It starts quickly, has easy electric shutdown, is durable, and is fuel-efficient, meeting stringent emission standards.
02. Efficient Compaction Technology
The WS205HD-3 single drum heavy duty road roller utilizes a closed-loop hydraulic system, consisting of an imported variable displacement pump and fixed displacement motor. This system achieves dual-frequency, dual-amplitude vibration. A scientifically optimized configuration of static linear load and excitation force ensures effective compaction of various material types and pavement thicknesses.
03. Advanced Drive System
To ensure excellent driving performance and gradeability, the WS205HD-3 road vibratory roller utilizes a closed hydraulic drive system consisting of a single pump with dual motors, an electronically controlled proportional pump, a motor, and a long-life reducer, providing full front and rear wheel drive. The WS205HD-3 comes standard with an automatic idle function to reduce energy consumption. Continuously variable speeds within a set speed range ensure optimal operation under varying operating conditions. (An optional automatic anti-slip mode is also available to minimize slip.)
01. Easy Operation
Single-lever operation enhances safety and reduces labor intensity.
02. Durable Design
The WS205HD-3 road vibratory roller vibratory wheel utilizes a four-point supported inner-cylinder vibratory chamber structure, offering simple construction, high strength, and excellent rigidity. It features dual-frequency, dual-vibration capabilities, high static pressure and excitation force, and high operating efficiency. Specialized vibratory bearings with integrated lubrication and cooling technology ensure long life and high reliability.
03. 25°(45%) Climbing Capability
The WS205HD-3 single-drum roller compactor features an advanced hydraulic system. This closed-loop hydraulic system, consisting of an imported variable displacement pump and variable displacement motor, ensures excellent driving performance and high gradeability. A two-speed continuously variable transmission ensures optimal speed operation under varying operating conditions.
04. Safe Brake System
The hydrostatic braking system, comprised of a hydraulic travel pump and a hydraulic drive axle, provides driving, parking, and emergency functions, ensuring safe and reliable operation.
05. Comfortable Operating Environment
The cab of this single drum roller compactor road heavy equipment features a well-sealed cabin, air conditioning, a suspended seat, and a spacious interior with extensive glass for an excellent field of vision, providing a safe and comfortable operating environment for the operator.
01. Maintenance Reminder
The audible and visual alarms on the road roller dashboard provide immediate maintenance and repair information, preventing equipment from operating while faulty and reducing the risk of damage.
02. Convenient Maintenance
The WS205HD-3 engine vibrating single drum roller cover at a wide angle for easy maintenance and servicing. This design allows operators to quickly access the engine components, streamlining routine checks and repairs. As a result, maintenance tasks can be completed efficiently, minimizing downtime and ensuring the roller remains in optimal working condition.
