Industrial robots equipped with six-axis articulated mechanisms execute high-speed, multi-directional movements in modern manufacturing. These cables, fiber optics, and pneumatic hoses subjected to severe mechanical stress during the robot's swiveling, rotating, and extending motions. The Tsubaki KabelSchlepp Robotrax System offers a specialized three-dimensional cable carrier designed to handle these complex robotic motions.
The Robotrax System employs a central steel cable running through the core of each chain link to absorb the primary tensile loads, preserving conductor integrity and extending cable service life. During rapid directional shifts and accelerations up to 10 g, this internal steel cable mitigates the primary tensile loads. A clamping piece allows easy calibration and adjustment of system tension, ensuring consistent mechanical support during long operational cycles.
The system's spherical link design and modular cable routing enable smooth flexing across three axes with radial rotation up to ±450 degrees per meter. The open, single-piece plastic links with snap-on connections prevent signal interference and mechanical abrasion between power lines, data channels, and fluid hoses. Installation and maintenance are simplified for standard models (R040 through R100), while larger configurations like R140X offer customized interior partitioning.
Tsubaki KabelSchlepp's Pull Back Unit (PBU) maintains optimal tension on the cable carrier and prevents destructive collisions caused by loose cable carrier loops swinging and striking the robot body. This active retraction mechanism requires no maintenance on its retraction element and offers standard mounting configurations for leading industrial robot platforms.
External impact shields limit the minimum bending radius and shield the chain body from severe external abrasion. If wear occurs, technicians can simply replace modular protectors rather than the entire cable carrier assembly. The Robotrax system accommodates demanding industrial environments with heat shields, protective covers, and LineFix strain relief devices, maximizing robot uptime and reducing total operational costs.
