Trækmoduler

Trækmoduler is a Danish term used in engineering and manufacturing to denote modular components that provide controlled pulling or traction within a mechanical system. They are designed to be grouped or stacked to form larger actuation solutions and are commonly employed wherever linear motion is required through tensioned elements such as cables, belts, or chains.

A typical trækmodul consists of a housing, a drive mechanism, a moving element, and a control interface. Drive mechanisms may be electric (stepper or servo motors with lead or ball screws), hydraulic, or pneumatic, and the pulling element can be a cable, wire rope, belt, or chain. The modular concept emphasizes standard interfaces, such as mounting patterns and electrical connectors, allowing different modules to be combined to achieve the desired stroke, force, speed, and control precision.

Trækmoduler are used in automation, material handling, robotics, stage machinery, and modular construction. They offer configurability, scalability, and easier maintenance, as modules can be swapped or reconfigured without redesigning the entire system. Limitations include wear of moving parts, backlash in screw or belt drives, and energy efficiency depending on the chosen drive type.

In relation to other terminology, the concept aligns with modular linear actuators or modular drive systems found in English-language engineering. Trækmoduler reflect a broader trend toward plug-and-play components in mechanical engineering. Related topics include linear actuators, modular automation, belt drives, hydraulic actuators, and pneumatic actuators.
