What distinguishes the Sumitomo HA60 from other asphalt pavers in its class?
When choosing an asphalt paver, construction companies look not only for productivity but also for low operating costs, reliability, and minimal site preparation time. This is where the Sumitomo HA60 stands out with a number of engineering solutions that reduce costs. dramatically and facilitate operators' work compared to competing machines in the same class.
1. J-Paver screed – working width from 2.3 to 6 meters without additional extensions
One of the most significant advantages of the Sumitomo HA60 is the stepless hydraulic extension of the J-Paver screed with a working range from 2.3 to 6 meters.
Unlike many competing machines that require installation of additional mechanical extensions for greater working width, Sumitomo allows work up to 6 meters without the need for such operations.
In practice, this screed covers the range of two conventional screeds, providing significantly greater site flexibility.
Lower transport costs
When asphalt paving is required with a working width between 5 and 6 meters, competing asphalt pavers require one of the following solutions:
• transport of a machine with a transport width of 3 meters, or
• machine with a transport width of 2.5 meters, equipped with additional mechanical extensions.
With Sumitomo asphalt pavers, this is not necessary. They achieve the required working width without additional mechanical extensions while maintaining compact transport dimensions.
Since the Sumitomo HA60 asphalt paver does not require installation of mechanical extensions when working up to 6 meters wide, the machine maintains its compact transport dimensions. This allows easy transportation by truck and trailer with a width of 2.5 meters, without the need to dismantle and reinstall additional components.
This brings direct economic benefits:
- transportation with a standard 2.5m truck;
- no extra work and equipment needed for extension installation;
- less time for machine preparation.
Less downtime on site
The absence of additional mechanical extensions means:
- shorter setup time;
- less assembly work;
- higher team productivity;
- reducing unproductive time.
2. Three-component compaction system STV
The system STV is one of the distinctive technological solutions of Sumitomo.
It includes:
Strike-Off profile
Strike-Off represents a static profile that pre-shapes and distributes the asphalt mix before final compaction.
Stamp
The stamp provides initial compaction of the material and helps achieve a uniform pavement structure.
Vibration system
Vibrations further increase compaction during paving.
Lower maintenance costs
Thanks to the presence of Strike-Off profile does not require the use of a heater in the stamp.
This eliminates one of the frequently replaced consumables on many asphalt pavers.
Experienced operators know that the stamp heater is usually replaced once a year. With Sumitomo this cost is eliminated, leading to lower maintenance costs and higher reliability.
3. Extendable end gates with hydraulic height adjustment
The screed features extendable end gates with hydraulic height adjustment.
The extendable end gate expands with the screed and steplessly adjusts the material amount hydraulically to avoid buildup in front of the screed.
Automatic locking of the screed
When the automatic locking system is activated, the screed’s lifting cylinders hold it to prevent sinking into the pavement when the machine stops. Upon restarting, the lifting cylinders remain pressurized long enough to “cut” the cooled asphalt in front of the screed, preventing unevenness.
Electric heating of J-Paver the screed
The screed is equipped with an electric heating system that ensures an even temperature across the entire working width.
This improves paving quality and creates optimal working conditions right from the start of the process.
For the machine itself
Powerful and economical YANMAR engine
Sumitomo HA60 is equipped with an engine YANMAR - 4TN107. In combination with the advanced technology of SUMITOMO, asphalt paver SUMITOMO NA60 provides high work efficiency and low fuel consumption. Engine YANMAR - 4TN107 meets the emission standards of Stage V on ES.
Smoother asphalt pavement
Smoother pavement, better evenness, and higher quality of the final result thanks to the undercarriage with bogie arms. The tilting pairs of rollers on the tracked undercarriage absorb surface irregularities, for example when passing over manhole covers.
Mechanical operator panel – proven reliability
Instead of complex electronic panels with touchscreens, Sumitomo uses a reliable mechanical operator panel.
This solution offers:
- easier maintenance;
- lower service costs;
- higher reliability in daily use, especially with oil-stained fingers;
- fewer expensive electronic components.
Independent control of the receiving hopper wings
The wings of the receiving hopper can be controlled independently of each other. This feature is useful for avoiding obstacles near the machine. It also allows more efficient operation depending on the amount of material in the hopper.
Adjustable auger height
The ability to adjust the height of the augers allows optimal distribution of the asphalt mix at different layer thicknesses.
The height of the augers can be hydraulically adjusted according to the thickness of the layer being laid. The adjustment switches are located on the operator's panel and behind the screed. Extensions and augers have their place within the machine itself, so there is no need to transport them separately.
Emergency operation system and process continuity
Sumitomo HAThe 60 is equipped with three interchangeable controllers.
If one controller fails, the others can take over its functions in emergency mode, allowing work to continue and asphalt to be laid without interruption.
Even in the event of a serious failure with 3 non-functioning controllers, an emergency mode is provided, allowing hydraulic pressures to be released manually. This enables the machine to be towed and loaded onto a transport vehicle without additional complications.
Conclusion
Sumitomo HA60 J Paver offers a combination of low transportation costs, quick preparation for work, high-quality asphalt laying, and proven reliability. These advantages make the machine the preferred choice for construction companies seeking maximum efficiency and minimal operating costs.
