Spiral Bar Bending Machine
Spiral Bar Bending Machine
The Spiral Bar Bending Machine is a specialized solution designed to bend steel bars into precise circular and spiral shapes with ease. Engineered for durability and versatility, it is widely used in the construction of columns, piles, and other reinforced structures requiring circular reinforcements. With its robust body, high-torque motor, and adjustable bending radius, the machine ensures smooth and accurate spiral formation.
Key Features:
Bar Bending Capacity: 6 mm to 28 mm diameter rebars
Operation: Manual or semi-automatic (model dependent)
Motor Type: Copper winding motor for long-lasting performance
Motor Power: 3 KW / 4 HP
Phase: Three-phase connection
Motor Speed: 1440 RPM for controlled and stable bending
