Heavy-Duty Plastic Cable Carriers


If you have larger applications that require a more robust cable carrier, you might want to step up to the heavy-duty plastic cable carrier. While made of the same material as the light/medium duty carriers, the four-piece construction of the heavy-duty carrier makes it a sturdy platform for larger applications. 

  • Durable Construction: Boasting plastic sidebands, the PKK system offers a wide variety of frame stays that offer robustness and longevity
  • Versatile Frame Stay Options: Choose from plastic bars or lids, round aluminum bars with plastic rollers, or wide aluminum bars or lids for enhanced strength, wear resistance, and added protection
  • Streamlined Installation: Each link comes with integrated mounting holes, often eliminating the need for additional mounting brackets, saving you time and effort
  • Enhanced Stability: Our locking link-to-link connection design increases strength and enables unsupported spans, ensuring reliable performance even in demanding applications
  • Easy Assembly/Disassembly: The fast stay assembly and disassembly design simplifies maintenance and adjustments, minimizing downtime
  • Exceptional Rigidity and Wear Resistance: Extremely rigid and wear resistant, ensuring reliable cable protection and reducing the risk of damage
  • Quick Length Adjustment: Enjoy quick and easy length adjustment to accommodate varying cable lengths and configurations, providing flexibility for your setup
  • Smooth Motion: Smooth motion right from the start, eliminating the need for break-in time
  • Travel Distance: The maximum distance of travel is determined by the arrangement and additional weight of the lines, but normal arrangement provides a maximum travel of double the free carrying length; travel distances up to 100 meters are possible
  • Travel Speed and Acceleration: There are no limits to travel speed or accelerations in general, but application-specific influences may limit this such as line weight (support rollers or similar constructive steps can increase this value)
  • Wide Temperature Range: Long term temperature limits are between -20°C and 100°C (-4°F and 212°F).

All of our systems are equipped with an integrated plastic connector. Additional components for attaching the energy chain are not required.

  • bending radii: 40 - 500 mm (1.57" - 19.69")
  • inner height: 16 - 80 mm (0.63" - 3.15")
  • inner width: 30 - 400 mm (1.18" - 15.75")
  • weight: 0.6 - 3.4 kg/m (0.40 - 2.28 lb/ft)


Long term temperature limits are between -20°C and 100°C (-4ºF - 212ºF).


The maximum range of travel is determined by the arrangement and the additional weight (line weight). At normal arrangement the maximum travel is double free carrying length. Support rollers or similar constructive steps can increase this value. Travel distances up to 100 meters are possible.


There are no limits for the travel speed in general, but with gliding arrangements application-specific influences have to be taken into account.


There are no limits for the accelerations, in general. Limits may occur through the tensile stresses at high line weights.


  • ELTOLA: silent running
  • ALLROUND: all movements
  • ATEX: EX-protection
  • ESD: antistatic
  • V-0: self-extinguishing



"The Hennig cable carrier is the easiest to integrate, easiest to use, easiest to open, easiest to reassemble, and is a long-lasting cable carrier....It has redefined our assembly process and made adding tools to a Star Lab enjoyable for our customers. I would highly recommend Hennig’s cable carrier to anyone who wants a quality, easy-to-use cable carrier."
