ROBOTRAX® System | System components
PBU pull back unit (for types R040, R056, R075, R085 and R100)
PBU: With fast movement sequences and large work envelopes, the relatively long carriers knock against the robot arm. The repeated impact significantly reduces the service life of the cable carrier and the cables within, and the entire system can fail. Downtimes cause high costs and problems in the manufacturing process – so they have to be avoided. » Compact design: fewer interfering contours and lower risk of collision » Maximum flexibility for cable carrier routing » No maintenance on the retraction element required » Standard mounting for KUKA, ABB and FANUC PBU is available for new robots, regardless of size, manufacturer, type or application, as well as retrofits and upgrades for existing workcells. It can be mounted vertically, horizontally or upside down. The extension length of the LSH 3 is 350 mm.

Protector The service life of the cable carriers and cables is significantly reduced by impact during fast movement sequences and in large work envelopes. The Protector protects the cable carrier against hard impacts, excessive abrasion and premature wear, while also acting as a limitation for the smallest bending radius. Downtimes are minimized. Not the entire cable carrier has to be replaced, but only the Protector in some cases.
