SUMITOMO has introduced its new asphalt paver, the HA90C-2, a model fully restyled for global markets based on the HA90C, which was built mainly for the Chinese market.
“The newly launched HA90C-2 has been developed based on the study of the paving operations in repair projects and tuned to the requirements of new road building projects, achieving more usability than ever. We are sure this machine will contributed to construction projects worldwide with its labour, cost and time-saving characteristics,” says a spokesman for the company.
The model was first displayed in Bauma China 2014, a leading trade fair for construction machinery, building material machines, and construction vehicles and equipment, held in Shanghai last November (25 to 28).
The HA90C-2 is equipped with a new screed, the J Paver2875. This new screed was developed by reinforcing the rigidity of the existing J Paver3075 (built for the HA90C) that has so far achieved commendable pavement precision and usability, he says.
Additionally, its transportation width has been improved to a minimum of 2.8 m, meeting the transportation width target of less than 3 m.
This screed has an infinitely variable extension system from 2.8 m to 7.5 m and can be further extended up to 9 m by adding two 0.75-m extension screeds at each end, he says.
Furthermore, the HA90C-2’s mould board operation is now hydraulic-driven resulting in easier operation and further improvement of pavement precision. As for the heating method, an electric heating system is available in addition to LPG (liquefied petroleum gas) heating system.
The hopper length has been extended by 200 mm to accommodate the larger dumptrucks. Also, the height of hopper front has been lowered to 550 mm while the dial-style steering system is also available.
Combined with lever operation, the system enables fine tuning in the pavement of curved or narrow roads.
Also, the operator’s cabin and both sides of the screed have colour monitors to display more information than ever including machine status and maintenance intervals.
