Pneumatic Traction Device for Fiber Optic Outdoor Cable Sheathing Line

The Pneumatic Traction Device is a key auxiliary machine designed for fiber optic and power cable production lines, specifically used in outdoor cable sheathing, insulation extrusion, armoring, and cable forming processes. It provides stable and precise traction to ensure consistent cable quality during continuous production.

This traction unit adopts a flat belt traction structure with pneumatic clamping, delivering uniform pressure and reliable gripping force without damaging the cable surface. With a well-engineered mechanical structure and flexible drive options, it is an ideal solution for modern cable manufacturing plants.

Product Structure & Design

The traction device features a robust frame fabricated from high-quality steel plates through precision bending and welding. Its compact and modern design ensures long-term stability and durability under continuous operation.

The transmission system consists of a motor-driven reduction gearbox with hardened helical gears, providing smooth power transfer, high load capacity, and low maintenance requirements. Both DC motor speed regulation and variable frequency (VFD) control are available to meet different production demands.

Pneumatic cylinders apply adjustable clamping force to the traction belts, ensuring secure cable pulling while minimizing deformation or abrasion, especially after extrusion and cooling.
