Hydraulic Road Roller Single Drum LTS208H With Cummins Engine 75kw Hot Sale
LTS208H Rear Hydraulic Driven Single Drum 8 tons Roller is a highly efficient and multi-functional compaction equipment, which is suitable for compaction work in various engineering fields. Its overall design is compact and its appearance is unique, with high value and practicality.

• Power performance: Adopting Cummins 4BT3.9 supercharged diesel engine with strong power of 75kW, it can operate stably and efficiently in various working environments, and it can operate normally even at a high altitude of more than 4000 meters.
• Compaction performance: the design of vibrating wheel is originated from German technology, with high excitation force and high compaction degree, which can ensure high-quality compaction effect, and the compaction effect is good for non-cohesive materials, such as gravel, crushed stone, sand and gravel mixture, sandy soil and so on.
• Operational performance: full hydraulic stepless speed + one-stick maneuvering design, making forward, reverse, start and stop operations become simple and convenient, hydraulic articulated steering, steering is light, turning radius is small, and it can turn flexibly in narrower environments.

»» Hydraulic System of Single Drum Roller LTS208
LTS208H adopts full hydraulic system, compared with the mechanical transmission system, it has the advantages of high transmission efficiency, smooth operation, low noise, easy operation and easy to realize automatic control. The design of full hydraulic stepless speed change + one-lever operation allows forward, reverse, start-stop and other operations to be completed by one lever, which greatly simplifies the operation process and improves the work efficiency.
Main hydraulic components ⇓

• Hydraulic Pump: The walking system adopts imported piston pump, and the vibration system adopts American Danfoss motor. The piston pump has the advantages of high volumetric efficiency, high output pressure and convenient flow adjustment, which can provide stable power for the traveling and vibration of the road roller.
• Hydraulic Motor:The hydraulic motor of the travel system is matched with the piston pump, which can efficiently convert the hydraulic energy into mechanical energy and drive the rear wheels to realize stepless variable speed travel. The hydraulic motor of the vibration system drives the vibrating wheel to produce high-frequency vibration to achieve good compaction effect.
• Control Valve: including pressure control valve, flow control valve and direction control valve. Pressure control valve is used to regulate the system pressure to ensure that the components work within the safe pressure range; flow control valve can precisely control the flow of hydraulic oil according to the need, so as to regulate the walking speed and vibration frequency, etc.; directional control valve controls the flow direction of the hydraulic oil, realizing the roller's forward, backward, steering and other actions.

Hydraulic system function ⇓

• Traveling function: hydrostatic rear wheel drive mode, through the cooperation of hydraulic pump and hydraulic motor, it realizes the stepless variable speed traveling of the road roller. This kind of drive mode makes the roller flexibly adjust the traveling speed according to the needs under different working conditions, whether it is low-speed and stable traveling during compaction work or high-speed traveling during transferring, it can easily cope with the situation.
• Vibration function: the front wheel vibrates hydraulically, and the hydraulic motor drives the vibrating wheel to generate excitation force. The design of the vibrating wheel of this roller is originated from German technology, with high excitation force and high compaction degree, which can ensure high-quality compaction effect. By adjusting the hydraulic oil flow and pressure of the vibration system, different vibration frequencies and amplitudes can be realized to meet the requirements of different compaction materials and working conditions.
• Steering function: hydraulic articulated steering mode, light steering, small turning radius. The hydraulic system realizes the flexible steering of the roller by controlling the action of the hydraulic cylinder in the articulated part, which can work in a narrow environment and improve the flexibility and efficiency of construction.
