FLEXIBLE & MOVING APPLICATIONS

Cables for drag chains, torsion and continuous movement.

Dynamically loaded applications place special demands on cable construction, materials and service life. GermanSTS supports the selection and sourcing of suitable cables for drag chains, robot axes and frequently moved routing.

APPLICATION-ORIENTED SELECTION

In moving applications, cable type alone is not enough.

For dynamic use, movement profile, bending radius, torsion, speed, stroke length, chemical/media exposure, temperature and expected service life determine the right construction.

This page follows an application-oriented approach: understand the load first, then align suitable cable constructions and sourcing paths — not only catalogue designations.

  1. Movement profile

    Drag chain, torsion, bending cycles, speed and acceleration.

  2. Construction & materials

    Stranding, sheath, shielding, conductor design and minimum bend radius.

  3. Operation & service life

    Environment, media, temperature and expected duty cycles.

SELECTION CRITERIA

Technical criteria for dynamically loaded cables.

A robust specification connects mechanical, electrical, environmental and project/installation requirements.

  • Mechanical

    • Bending radius and guidance
    • Torsion and rotation angle
    • Speed, travel and cycles
    • Abrasion, tension and support

  • Electrical

    • Voltage, current and cross-section
    • Signal and data transmission
    • Shielding and EMC
    • Conductor structure and stranding

  • Environmental

    • Oil, chemicals and media
    • Temperature and humidity
    • Dust, particles and abrasion
    • Indoor or outdoor conditions

  • Project / Installation

    • Routing system and energy chain
    • Approvals and standards
    • Documentation and datasheets
    • Availability and delivery

APPLICATION ENVIRONMENTS

Typical use contexts for moving cables.

Each moving application has its own load profile — the right cable follows from guidance, cycles and environment.

  • Drag chains

    Continuous movement in energy chains with defined bend radius, abrasion and cycle load.

  • Robotics / robot axes

    Repeated torsional and bending load on axes, end effectors and rotary tables.

  • Handling systems

    Flexible cables for grippers, transfer units and positioning equipment.

  • Automated machinery

    Moved routing in production cells with repeated stroke and travel motion.

  • Packaging & assembly

    Compact guidance, high cycle rates and often tightly constrained bend radii.

  • Continuous motion routing

    Continuously moving cable paths with service-life and maintainability requirements.

WHY SELECTION MATTERS

Common risks of unsuitable cable selection.

A cable that fits electrically can still fail mechanically or environmentally — with direct impact on uptime and maintenance.

  • Premature wear

    Excessive cycle load or unsuitable stranding shortens usable life.

  • Sheath cracking

    Wrong sheath material or too-tight bend radius causes cracks and exposure.

  • Conductor failure

    Repeated bending or torsion can damage conductors and cores early.

  • EMC issues

    Insufficient shielding — or shielding stressed by motion — disturbs signals.

  • Insufficient service life

    Construction and movement profile do not match the planned service period.

  • Routing / installation mismatch

    Cable and guidance system are not aligned to each other.

SELECTION & SOURCING

From movement profile to a suitable cable.

We structure selection and sourcing around the real application — not only around product names.

  1. 01

    Assess movement profile

    Capture drag chain, torsion, cycles, speed, stroke and guidance.

  2. 02

    Define cable requirements

    Set mechanical, electrical, environmental, standards and documentation needs.

  3. 03

    Match suitable constructions

    Review fitting cable families and constructions against the duty profile.

  4. 04

    Confirm availability & sourcing

    Align supply options, alternatives and project-focused procurement.
