0370250134 - ESAB SD-15 Powered Turning Roll Drive Unit 7.5 Ton

Industrial Welding Automation with the ESAB SD-15 Roller Bed

The ESAB SD-15 Drive Roller Bed is a robust solution designed to enhance productivity and safety in heavy industrial welding applications. Engineered for the fabrication of cylindrical vessels, pipes, and tanks, this 7.5-ton capacity drive unit provides the powered rotation necessary to achieve consistent, high-quality circumferential welds. By automating the rotation of the workpiece, the SD-15 allows welders to maintain a steady torch position, significantly improving weld bead uniformity and penetration, particularly in processes like Submerged Arc Welding (SAW), MIG, and TIG.

Heavy-Duty Construction and Capacity

Built to withstand the rigors of a busy fabrication shop, the SD-15 features a sturdy chassis and durable wheel components capable of handling loads up to 7.5 tons. This drive unit is the powerhouse of your turning roll setup, equipped with a motor and gear system designed to deliver smooth, jerk-free rotation even at low speeds. This stability is critical when welding large diameter pipes or heavy-wall vessels where any fluctuation in speed can lead to weld defects. The unit is typically paired with a matching idler unit (sold separately) to support the full length of the workpiece.

Versatility and Adjustment

One of the key features of the ESAB SD-15 is its adjustability. The wheel center distances can be easily modified to accommodate a wide range of workpiece diameters. Whether you are working on smaller process piping or larger storage tanks, the roller bed can be configured to provide optimal stability and traction. The wheels themselves are designed to provide excellent grip without damaging the surface of the workpiece, ensuring that the rotation is translated effectively from the drive motor to the cylinder.

Operational Efficiency

Integrating a roller bed into your welding workflow drastically reduces the non-arc time associated with manual repositioning. Instead of stopping to rotate a pipe with a crane or manual bar, the operator can control the rotation continuously. This not only speeds up the welding process but also reduces the physical strain on the welder and minimizes the risk of accidents associated with handling heavy loads. The ESAB SD-15 is an investment in both throughput and workplace safety, making it an essential asset for any shop serious about large-scale fabrication.
