Application of H-Beam PTW Welding Machine Duplex Drive Sprocket
Built for Heavy-Duty Power Transmission in Welding Lines:
Used in H-beam PTW (Profile Travel Welding) machines to deliver robust duplex roller chain drive performance. This sprocket ensures reliable torque transfer and synchronized motion across multiple welding axes during structural beam fabrication..
Optimized for High Load, Precision, and Durability:
Engineered with a duplex (double-strand) chain design to handle greater torque and load capacity. The dual-hub construction enhances rigidity, ensuring vibration-free, stable power transmission under demanding welding operations. Made from EN-8 steel with a blackened surface finish for superior wear and corrosion resistance in industrial environments.
Trusted by Leading Welding Equipment Manufacturers:
Used by Mansoori Weldarc Pvt. Ltd., Weldarc Automation, Mitool Equipments, Technocrat Automation, Weldwell Speciality Pvt. Ltd., and Sree Sai Equipments—as well as other heavy fabrication and steel structure machinery producers.
Summary
A high-strength, duplex sprocket designed for H-beam PTW welding machines, ensuring dependable, smooth, and long-lasting power transmission in heavy fabrication setups.
