Cylindres de puissance Porta creux

High-Performance Hollow Hydraulic Cylinders for Pulling, Tension & Lifting Applications

Notre Cylindres de puissance Porta creux are designed to deliver powerful hydraulic force for demanding pulling, tensioning, levage, pousser, and positioning applications. Featuring a hollow plunger, these hydraulic cylinders allow threaded rods, câbles, and pull bars to pass through the center of the cylinder, making them the ideal solution for applications where conventional solid cylinders cannot be used.

Manufactured from premium alloy steel and engineered for long-term reliability, these hollow hydraulic cylinders are widely used in construction, bridge engineering, entretien d'équipement lourd, exploitation minière, construction navale, railway projects, et fabrication industrielle.

Available in capacities ranging from 13 Tonne à 95 Tonne, our hollow cylinders provide outstanding performance in the most demanding environments.
