Spring Reels
Built to Perform!
Conductix-Wampfler spring reels range from small extension reels to big automatic reels.
- Extension spring reels are equipped with a ratchet so that the user can pull out the cable or hose length he needs and freely use it. After use, a pull on the cable releases the ratchet and the spring rewinds the cable. Extension reels are used to feed handheld tools and small movable appliances or to charge Electric Vehicles (EV).
- Automatic spring reels exert a permanent tension on the cable or hose. The mobile machine pulls on the cable or hose which progressively tensions the springs. When the machine moves back, the springs automatically rewind the cable or hose. Typical applications are foundry transfer cars, handling cranes, grabs, grips and magnets for overhead cranes, attachments and sensors for mobile and telescopic boom cranes.
As quality and reliability starts with the design, we use rules-based design systems to offer you the configured spring reel best adapted to your application within our fully industrialized range, plus a finishing touch from our experts if required.

FAQs
Frequently asked questions
How can I extend the lifespan of the cable in my spring reel system?
Quality matters: make sure you use a solid, proven and tested reeling cable, sized to your reel and application. Conductix-Wampfler tests, recommends, and holds in stock suitable reeling cables.
The tension of the cable must be steady at start and stop of the movement and along the travelling distance.
The anchoring is sometimes neglected: use a cable grip (= sock) to transfer the pull deep into the cable with a spring to absorb shocks. For bigger cables, a bent anchor, or even an anchor drum is recommended. Conductix-Wampfler holds in stock anchors adapted to most cables and applications.
It is very important not to sharply bend the cable on a small roller: only use sheaves or diverters properly sized to the angle and to the minimum bending radius of the cable. We can recommend you the proper diverter if it was not installed up front.
My spring reel is not running smoothly, what can I do?
First of all, check if the application travel length, speed, acceleration and cable match the reel’s datasheet and restore the initial reel setup.
Carefully, slowly and safely release the pre-turns and reinstall the specified number of pre-turns (attention, the springs store high energy and to be safe, this action must be carefully done by trained technicians: when in doubt, ask our representative near you)
If you cannot resolve the problem, or if the reel’s datasheet does not fit the application anymore, call our nearest representative for assistance. In most cases, we can recommend a new setup for a Conductix-Wampfler reel, but sometimes a new reel will be required.
My application now requires more power and longer travel, can I change for a bigger/longer cable?
The reels and their slip rings are sized from initial specification, so the general answer is “bigger or longer cable may not wind properly, and higher intensity may overheat the cable or slipring ”.
However, if you send us a photo of the nameplate on the Conductix-Wampfler reel, or its original datasheet and specifications, plus the updated requirements, in most cases we can retrieve the design file and quickly tell you if higher power and/or longer cable still fits. Sometimes we will need to ask you for more application data.
