🔍 Details of Model:D138HF Tandem roller

Hydraulic system

The closed hydraulic system is composed of Danfoss high-pressure plunger pump and motor, ensuring that the roller has good driving performance and high climbing ability. Hydraulic continuously variable transmission ensures operation at the most suitable speed under different working conditions. Both economically viable and efficient.

Vibration wheel structure

The vibration wheel adopts a four point support inner cylinder vibration chamber structure, with high strength and good rigidity, equipped with impact resistant reinforced imported vibration bearings to ensure bearing performance; The carefully designed bearing seat with lubricating oil passage has good lubrication and heat dissipation performance. Even under strong alternating loads, it can still ensure the excellent performance and long-term reliability of the vibration bearing, ensuring efficient construction efficiency.

Wheel reducer

The braking system consists of multiple wet brakes on the vibrating wheel reducer and static hydraulic brakes on the closed hydraulic system. It has three functions: driving, parking, and emergency,ensuring safe and reliable driving.

Data display system

The sound and light alarm device on the dashboard can provide maintenance and repair information at any time, avoiding equipment operation with "disease" and preventing equipment damage. The ultra large color LCD screen displays various machine information in real-time, making operation simple and convenient.By placing the throttle handle and forward/backward handle to the right, the comfort of operation is improved.

Vibration system

The closed vibration system is composed of Danfoss vibration pump and vibration motor, with dual frequency and dual amplitude,scientifically and reasonably configured static line load and excitation force, ensuring effective compaction of different types of materials and thicknesses of paving layers.

Density tester

Choose a compactness detector to directly observe the compaction quality in the cab

Edge cutter

Optional edge cutter for road edge cutting operations.

Engine

Cummins engine, with a power of 119kW, has strong power, fast starting, durability, and fuel economy

Sprinkler system

Large capacity water tank, ensuring continuous construction of the whole machine, three-stage filtration, electrically controlled pressure spraying water system, with the option to spray water continuously or intermittently.
