Combining the power of the heavy duty HL unit with the straightening performance of 11 work rolls (6 upper and 5 lower), the HL unit gives material a high degree of flatness to materials up to 6.0mm thick.

The work rolls on the HL can be opened to a maximum of 20 degree, making roll cleaning much easier. The machine was designed to allow easy access to the inside structure for improved maintenance.

■Side Gear System
The feed roll is equipped with gears that drive each roll, making the lower work rolls run.

■All Rolls Driven with Universal Joint System
This system makes all rolls through universal joints which connect each roll by a motor-driven parallel gear box. This system is especially recommended for both high tension materials and easy-to-slip materials.

A wide variety of information needed for planning, operation, maintenance, etc., is uniformly controlled under the base mode of “Settings, Planning, Operation, and Maintenance”. Equipped with various new operations, it is a complete operation system that responds to diversification and sophistication of merchandise and reduction of work time.

All rolls drive system (HLU model) * and frame rigidity improvement (four times higher than the conventional equipment) have enabled straightening of high-tensile steel plate.
