1-, 2- and 3-axle rotary lifting systems for heavy components, vehicle frames, chassis and steel assemblies
An industrial rotary device with a lifting function enables the safe rotating, turning, lifting, and positioning of heavy components in production, assembly, maintenance, and welding. These systems are used wherever workpieces need to be ergonomically accessible, precisely aligned, and machined from multiple sides.
Typical areas of application include vehicle manufacturing, commercial vehicle production, plant engineering, crane construction, steel construction, mechanical engineering, the defense industry, military technology, special vehicle construction, and the production of large steel components . Depending on the application, the system can be configured as a rotary system, rotary and turning system, turning device, welding positioner, welding manipulator, workpiece positioner, or lifting and rotating system .
The rotating device is suitable for components such as vehicle frames, truck frames, chassis, axle components, machine frames, welded assemblies, crane components, special constructions, and heavy industrial components . Controlled rotation and positioning allow welding, assembly, testing, and rework processes to be carried out much more efficiently and safely.
Depending on the task , 1-axis rotary systems , 2-axis rotary lifting systems , or 3-axis positioning systems are available. These allow components not only to be rotated but also lifted to an ergonomic working height and positioned in multiple degrees of freedom. For particularly large or heavy workpieces, heavy-duty rotary devices , heavy-duty tilting devices , and customized solutions are used.
The robust design is engineered for continuous industrial use. Motorized rotary and lifting movements, defined rotational speeds, high torques, and stable mounting points ensure controlled machining of heavy workpieces. As a result, an industrial turning and rotating machine not only improves workplace ergonomics but also process reliability, repeatability, and productivity.

FAQ – Industrial Rotary Device / Turning Device
What is an industrial rotary device?
An industrial rotary device is a technical system for the controlled rotation, turning, and positioning of heavy workpieces. It is used to bring components into an ergonomic and safe working position for assembly, welding, testing, coating, or maintenance.
What is the difference between a rotary device and a reversing device?
A rotary device rotates a component around a defined axis. A turning device is primarily used to safely turn or tilt heavy workpieces. In practice, the two terms often overlap, which is why terms such as rotary and turning system , rotary lifting system , or workpiece positioner are also used.
What is a rotary lifting station?
A rotary lifting system combines a rotation function with a lifting function. This allows the workpiece not only to be rotated, but also raised or lowered to an ergonomic working height. Such systems are frequently used for large frames, chassis, steel assemblies, and heavy industrial components.
For which materials can rotary devices be used?
Rotary devices can be used for steel, stainless steel, aluminum, cast iron, sheet metal assemblies, tubular frames, profile structures, composite materials, engineering plastics, and mixed constructions .
