Durable Compactor Road Roller Diesel Type

Product Details

This introduction showcases two 4000kg single-drum vibratory rollers developed on the same platform: one with power-shift mechanical drive and the other with full hydraulic drive. While sharing a core architecture, they differ in their drive mechanisms and key performance characteristics to meet diverse construction needs.

I. Common Core Specifications

Both machines share an identical basic platform:

The overall operating weight is 4000 kg.

The vibratory drum dimensions are uniform: 1300 mm wide and 1000 mm in diameter, providing a consistent compaction width.

Similar mobility: Both have a wheelbase of 2285 mm and a minimum turning radius of 4980 mm, offering comparable maneuverability.

Both are powered by a Yunnel YN27PAF4 Euro IV emission standard engine with a rated power of 36.8 kW, ensuring reliable power.

The vibration amplitude is 0.52 mm for both.

The overall length and width are identical: 4040 mm and 1430 mm, respectively.

II. Main Performance Differences and Features

1. Power-Shift Mechanically Driven Single-Drum Vibratory Roller

Drive and Speed: Employs a mechanical power-shift gearbox, providing four fixed speeds: 2.5, 4.5, 7.5, and 13.2 km/h. Its high-speed gears enhance its efficiency for moving between work sites.

Compaction Performance: Features stronger static linear pressure (132 N/cm) and greater excitation force (72 kN), with a vibration frequency of 55 Hz. This makes it excellent for compacting deep soils, rockfill, and other conditions requiring high impact energy.

Grading Ability: 30%.

Summary of Features: This model boasts powerful compaction capabilities, high operating efficiency, and economy, making it a reliable choice for traditional large-scale earthwork compaction tasks.

2. Fully Hydraulically Driven Single-Drum Vibratory Roller

Drive and Speed: Utilizes an advanced hydrostatic drive system, enabling continuously variable speeds from 0 to 7.5 km/h. The operation is extremely smooth, enabling precise micro-motion control and completely eliminating shift shock.

Compaction Performance: Its static linear pressure (125 N/cm) and excitation force (65 KN) are slightly lower than the mechanical model, with a vibration frequency of 52 Hz, but the hydraulic system provides more stable and continuous vibration output.

Climbing Ability: Improved by 35%, the hydraulic transmission offers better traction distribution and performance when working on slopes.

Overall Height: Slightly lower, at 2470 mm.

Features Summary: This model's core highlights are superior operating comfort, stepless speed regulation for precise control, and enhanced climbing performance. It is particularly suitable for asphalt pavement compaction, bridge abutment backfilling, narrow areas, and complex conditions requiring high flatness with significant slope variations.

III. Purchase Recommendations: If your construction focus is on large-scale earthwork projects such as roadbeds and dams, pursuing the highest compaction efficiency and single-pass compaction effect, and your budget is relatively limited, the mechanical drive model is the classic choice. If you prioritize ease of operation, flexibility in adapting to complex and changing working conditions, and the ability to perform fine surface compaction, the fully hydraulically driven model will offer significant improvements in construction quality and efficiency.

In conclusion, both models represent mature and reliable technologies, allowing users to make the most suitable choice based on specific project requirements, working conditions, and expected return on investment.
