Modern automated manufacturing facilities rely heavily on six-axis articulated robots executing high-speed, multidirectional maneuvers under demanding operational cycles. According to technical specifications provided by Tsubaki KabelSchlepp, as these robot arms swivel, rotate, and extend, the internal electrical cables, fiber optics, and pneumatic hoses supplying them endure severe mechanical stress. Torsional twist, rapid acceleration, and repeated contact with machine structures frequently trigger premature conductor fatigue, insulation breakdown, and costly unplanned production halts across automotive welding cells and high-speed machining centers.
Managing High Tensile Forces With Central Steel Technology
To combat multi-axis motion challenges, the Tsubaki KabelSchlepp Robotrax System introduces a specialized three-dimensional cable carrier engineered specifically for complex robotic motion. Conventional cable carriers typically transfer operational movement stress directly onto internal electrical lines and hoses. The Robotrax system alters this dynamic through a central steel cable running through the core of every chain link, as detailed in product documentation. Accelerations reaching up to 10 g combined with sudden changes in direction cause this core steel cable to take on the main pulling forces. Shielding fluid and electrical conduits from stretching forces protects the conductors from damage and significantly prolongs the operational lifespan of the cabling. Technicians can regulate and tune the system’s tension effortlessly via a built-in clamping element, guaranteeing uniform mechanical backing throughout extended working periods.
Spherical Link Design and Modular Cable Routing
The foundation of the Robotrax system relies on open, single-piece plastic links featuring spherical snap-on connections on both sides. This geometry allows the carrier to flex smoothly across three axes, providing radial rotation of up to plus or minus 450 degrees per meter depending on the model size. To optimize internal organization, carrier links contain up to three distinct chambers that prevent signal interference and mechanical abrasion between heavy power lines, sensitive data channels, and fluid hoses. For standard models ranging from R040 through R100, technicians press cables directly into the carrier without tools, which cuts installation and maintenance time. For bigger builds like the R140X, the system features rotating crossbars equipped with snap fasteners, supplemented by horizontal and vertical separation elements for tailored internal layout management.
Active Retraction and Impact Protection for Complex Work Envelopes
Large robot work envelopes and high-speed motion trajectories often cause loose cable carrier loops to swing and strike the robot body. The Pull Back Unit is built into the Tsubaki KabelSchlepp setup to prevent these harmful impacts, acting as a dynamic winding system that keeps the cable carrier under proper tension during every phase of movement. By preventing excess slack and eliminating interfering contours, the Pull Back Unit minimizes collision risks across complex movement paths while requiring zero maintenance on its retraction element for industrial robot platforms including KUKA, ABB, and FANUC. Additionally, external protectors can be retrofitted onto individual chain links to limit the minimum bending radius and shield the chain body from severe external abrasion.
