In modern automated manufacturing, the Tsubaki KabelSchlepp Robotrax addresses the heavy mechanical loads that cables, fiber optics, and pneumatic lines face on six-axis robotic arms. As articulated robots twist and accelerate, lines are exposed to torsion, rapid acceleration, and contact with surrounding structures. According to the company, this system is designed to mitigate premature conductor fatigue, insulation wear, and unexpected production stoppages.
Tsubaki KabelSchlepp Robotrax central steel load path
The Robotrax cable carrier is engineered to decouple tensile forces from internal lines. A central steel cable runs through the core of each link to absorb primary tensile loads during fast directional changes and accelerations that can reach up to 10 g. By isolating electrical and fluid lines from pulling forces, the design aims to preserve conductor integrity and extend service life.
Technicians can set and adjust cable tension using an integrated clamping element to maintain consistent support through long duty cycles. In related efforts to expand engineering capabilities, researchers have explored how AI unlocks lower-cost GRCop-42 3D printing on common machines for aerospace-grade components.
Spherical links and modular routing options
The system uses open, single-piece plastic links with spherical snap connections on both sides, allowing smooth three-axis movement. Depending on size, the carrier supports radial rotation of up to ±450 degrees per meter. Internally, links can be configured with as many as three chambers to separate power, data, and fluid lines.
For standard sizes, identified as R040 through R100, cables can be pressed into place without tools to speed installation and maintenance. Larger models, such as the R140X, add swiveling crossbars with snap locks and vertical or horizontal dividers for custom partitions.
Active retraction and impact safeguards
To prevent loose carrier loops from striking the robot during large sweeps at speed, Tsubaki KabelSchlepp integrates a Pull Back Unit, or PBU. The PBU keeps constant tension on the carrier, reducing slack and minimizing collision risks along complex paths.
The retraction element is described as maintenance free, and mounting options are available for major industrial robot brands including KUKA, ABB, and FANUC. External protectors can also be added to specific links to enforce a minimum bend radius and shield against abrasion.
If wear occurs, the modular protector can be replaced without changing the full carrier assembly.
Configured for harsh industrial settings
The Robotrax lineup can be equipped with accessories for demanding environments, including:
- Heat shields: Aluminum-coated textile covers to resist radiant heat, weld spatter, and sparks.
- Protective covers: Coated polyester sleeves to protect against cutting fluids, hydraulic oils, paint overspray, and abrasive dust.
- LineFix strain relief: Multi-layer clamping to secure cables at both ends and limit axial movement during intense motion.
By combining central load absorption, multi-axis flexibility, and active retraction, the Tsubaki KabelSchlepp Robotrax is positioned as a way for plant engineers and integrators to increase robot uptime and curb total maintenance costs.
