Prestressed Tensioning Machine

🌍 Product Overview

The Prestressed Tensioning Machine is essential equipment in precast concrete slab production lines, designed to stretch steel strands or rebars before concrete casting.

By applying controlled tension, the machine ensures the prestressed force is accurately transferred into the concrete, producing strong, crack-resistant, and long-span slabs.

It is widely used in the production of hollow core slabs, precast beams, lintels, and other prestressed concrete components.
