Rullo stradale vibrante a doppio tamburo da 3 tonnellate

3 Ton Double Drum Vibratory Road Roller Overview

The HT-JS1200 3 Ton Double Drum Vibratory Road Roller is a full-hydraulic compaction machine designed for wide application, reliable performance, convenient operation, and long service life. With a 3140 kg operating weight, front and rear steel drums, hydraulic dual-wheel drive, and dual-wheel vibration, the machine provides stable travel and consistent compaction performance.

Il Rullo stradale vibrante a doppio tamburo da 3 tonnellate has a travel speed range of 0–12 km/h and uses stepless speed control, allowing the operator to adjust the travel speed according to different working requirements. Its 3500 mm turning radius, 30% gradeability, and articulated frame structure support flexible movement and operation on the jobsite.

Full-Hydraulic Travel and Working System

The HT-JS1200 is equipped with a hydraulic dual-wheel drive system. An international-brand Hansa-TMP variable piston pump with a displacement of 28 forms the core of the hydraulic system, supporting stable power transmission and stepless speed adjustment.

French Poclain cycloidal hydraulic motors provide dual-wheel drive travel. The combination of the variable piston pump and hydraulic motors helps the 3 Ton Double Drum Vibratory Road Roller maintain stable operation during travel and compaction.

NSK high-precision mounted radial ball bearings are also used to support the overall operating performance of the machine. These established hydraulic and bearing components contribute to the dependable working characteristics and long service life of the roller.

Dual-Drum Vibration and Compaction Performance

The compaction system of the 3 Ton Double Drum Vibratory Road Roller uses hydraulic vibration on both the front and rear drums. The machine provides a nominal amplitude of 0.5 mm, a vibration frequency of 75 Hz, and an exciting force of 35 kN × 2.

The static linear load is 125 N/cm at the front and 87 N/cm at the rear. Front and rear hydraulic wheel vibration provides stable excitation and quick vibration startup, helping the machine deliver consistent compaction during operation.

Front and rear dual-wheel vibration is supplied as standard. A front-wheel single-vibration configuration is available as a custom option. This vibration system allows the 3 Ton Double Drum Vibratory Road Roller to meet different operating requirements while maintaining straightforward control.

Changchai Diesel Engine

Power for the HT-JS1200 3 Ton Double Drum Vibratory Road Roller is supplied by a Changchai ZN390B diesel engine. The engine is a vertical, three-cylinder, water-cooled electronic-injection model that meets China Stage III emission standards.

With a rated power of 39 HP at 2600 rpm, the engine provides strong power and easy starting. The fuel tank has a capacity of 36 L, while the specified fuel consumption is 240 g/kW·h. The engine and hydraulic system work together to support travel, steering, vibration, and other machine functions.

Articulated Hydraulic Steering

The front and rear frames of the 3 Ton Double Drum Vibratory Road Roller are connected through an articulated structure. Hydraulic power steering makes directional control convenient and supports smooth maneuvering during compaction work.

With an overall length of 2700 mm, an overall width of 1320 mm, and a turning radius of 3500 mm, the roller combines a compact machine structure with practical steering performance. Its overall height without the anti-collision beam is 1900 mm.

Electric-Control Water Spraying System

The HT-JS1200 uses an electric-control pressure water spraying system. The pressure water pump produces atomized spraying and distributes water evenly across the drum surfaces.

Convenient electric switching simplifies water spraying control during operation. The atomized design also improves water saving while maintaining even coverage. This system supports the continuous operation of the 3 Ton Double Drum Vibratory Road Roller by helping keep the front and rear drums properly sprayed.

Front and Rear Steel Drums

Both the front and rear drums have a width of 1200 mm and a diameter of 710 mm. The matching drum dimensions complement the dual-wheel vibration system and provide a consistent working width during compaction.

The front and rear hydraulic vibration design allows both drums to participate in the compaction process. Combined with the specified vibration frequency, amplitude, exciting force, and static linear load, the 3 Ton Double Drum Vibratory Road Roller provides stable and efficient operation.

LED Lighting for Night Construction

High-efficiency LED lights are installed at both the front and rear of the machine. These lights provide illumination for construction and compaction work carried out at night.

The front and rear lighting arrangement improves visibility around the working area. Together with hydraulic steering, stepless travel speed control, and convenient electric water spraying, the lighting system supports practical operation under different working conditions.
