Overview

The Bota Head & Tailstock Series provides the ideal solution for welding long structures such as trailer chassis, railway cars, and excavator booms. Unlike single-column positioners, this dual-support configuration secures the workpiece at both ends, effectively eliminating bending or torque distortion caused by gravity. The Tailstock can be mounted on rails to accommodate variable workpiece lengths, offering maximum flexibility for your production line.

Features

  • The robust double column support system secures the workpiece from both ends to eliminate the risk of sagging common with single column machines.

  • An adjustable rail mounted tailstock allows you to easily change the distance between columns to accommodate various workpiece lengths.

  • The dual support design guarantees distortion free rotation by minimizing torque stress on long frames and chassis during operation.

  • We offer an optional synchronized dual drive configuration that ensures both the headstock and tailstock rotate in perfect unison.

Bota welding positioners offer 360° rotation and multi-angle tilting to keep workpieces in optimal welding position. They support standalone or automated use and are ideal for pressure vessels, machinery, and more.

Eliminate Structural Distortion

When welding long, heavy frameworks—such as truck chassis or architectural beams—on a standard single-column positioner, the “cantilever effect” often causes the workpiece to sag or twist under its own weight. This physical distortion compromises geometric accuracy and leads to misaligned weld seams. Bota solves this by supporting your workpiece from both ends. Our synchronized headstock and tailstock system effectively neutralizes gravity, creating a rigid, stable axis of rotation. This ensures the part remains perfectly straight throughout the 360° welding process, eliminating the need for costly post-weld straightening and guaranteeing consistent structural integrity.

Adapt to Variable Lengths

In heavy fabrication, project requirements change rapidly. A fixed-length setup limits your workshop’s capability. Bota empowers your production with a movable tailstock mounted on precision floor rails. This design allows operators to easily slide and lock the unit to accommodate a vast range of workpiece lengths—from short hoppers to extra-long trailer frames. By transforming a single equipment setup into a versatile welding station, we help you maximize equipment utilization and Return on Investment (ROI), significantly reducing changeover time between different product batches without the need for multiple specialized fixtures.
