Sumitomo’s larger paver

2714 Sumitomo has developed a larger, high performance paver to meet the needs for productive highway class machines in export markets. The new HA90C-2 is based on the earlier HA90C paver, which was only sold in China and also shares a common design and layout with the existing and well-proven HA60C/W. However the new HA90C-2 offers increased production and performance and has two new screeds allowing more paving options.

The firm has recognised that markets outside of Japan favour larger pavers and has developed the new machine from the HA90C to meet this demand, while retaining features such as the innovative overlapping screed system.

The new J-2875 screed on the HA90C-2 is a development of the earlier J-3075 screed fitted to the HA90C, but has a wider range of widths available. The new design offers hydraulically adjustable paving widths from 2.8-7.5m, compared to 3-7.5m for the earlier design. This narrower minimum width is of importance as it means the machine is easier to transport. Meanwhile electric heating is offered as an option, in addition to the LPG heating system available for the earlier screed design. Maximum paving width for the HA90C-2 is 9m when the machine is fitted with bolt-on extensions.

For the Chinese market, the HA90C-2 has a 200mm longer hopper with its front lowered to 550mm, to suit the larger trucks used by contractors. In addition, the paver can also be fitted with the J-2360 screed, with hydraulically extendable paving widths from 2.3-6m and is also offered with electric or LPG heating.
