Hydraulic, Plate Rolling Machine (4 Roll Type)

4 ROLL TYPE / DOUBLE PRE-PINCH TYPE / HYDRAULICALLY DRIVEN ROLLS

4 Rolls, Heavy Duty, Hydraulic Plate Rolling Machines produced by ABL have both the upper and the lower roll powered with hydraulic motor and planetary gear box. Rolls made of forged steel & all movements of rolls are hydraulic powered. The hydraulic motors of the two central rolls are coupled to their epicycloid gear boxes. The gear boxes are mounted directly on the rolls without secondary transmissions; this way there is no loss of power and no need of parts maintenance. Massive torsion bars grant the absolute parallelism. These torsion bars, together with all the hydraulic device, generate a system that gives absolute precision and versatility.

Planetary Gearboxes

Planetary drive eliminates complicated transmission systems which are not energy efficient. Delivers in excess of 98 % of all created energy to roll surface. Also eliminates the need for clutches and complicated synchronization devices

Planetary Guides

By using planetary guides, available on ABL Plate Rolls, we are able to keep approximately 50% more area of the plate under bend pressure during the rolling operation, thereby allowing our Plate Rolls to roll down to 1.1 the upper roll diameter. This allows the Rolls to have a 30% advantage on tight diameters.

Body Structure

The strong structure is designed to fight the flexions due to the working effort, and it allows the top roll balancing, everything for the benefit of the final result accuracy. Also, the design is such that it requires minimum foundation work during installation at site.

Torsion Bar Parallelism

Unlike electronic systems or proportional value systems, which maintain a theoretical balance, ABL Plate Rollers maintains a mechanical finite parallelism through our exclusive torsion bar system which allows the machine to be adjusted to its full conical tilt and back to parallel in only seconds for the life of the machine.
