Cradle Type Welding Positioners for Heavy Cylinders, Pipes, Pressure Vessels, and Large Structural Welding
HALDEN cradle type welding positioners are designed for rotating, positioning, and supporting heavy cylindrical workpieces during welding, cladding, fabrication, assembly, and repair. The cradle-style support structure improves rotational stability for large pipes, pressure vessels, tanks, wind tower sections, and heavy fabricated components while helping reduce manual handling and improve weld accessibility.
Heavy Cylindrical Workpieces Become Difficult and Unsafe to Weld Without Stable Rotation and Positioning.
A cradle type welding positioner helps rotate and support large vessels, pipes, and structures safely while improving welding accessibility and process stability.
What Is a Cradle Type Welding Positioner?
A cradle type welding positioner is a heavy-duty rotating support system designed to hold cylindrical or irregular workpieces during welding and fabrication. The cradle structure supports the workpiece from both sides and rotates it through rollers or driven supports, helping operators maintain proper welding position while reducing manual repositioning.
Stable Heavy-Duty Support
The cradle frame helps distribute workpiece load more evenly during rotation and welding.
Controlled Workpiece Rotation
Variable-speed drive systems help operators control welding speed and rotational positioning.
Improved Welding Accessibility
Rotating the workpiece into optimal welding position helps improve operator ergonomics and welding consistency.
Typical Applications of Cradle Type Welding Positioners
Cradle welding positioners are widely used for large-diameter cylindrical workpieces and heavy fabricated components across multiple industries.
