Cable carriers

Rol-E-Chain cable carriers have built-in wheels to facilitate travel over long distances, such as on a crane.

Features & benefits

  • Wheels are integrated into the cable-carrier's side links and reduce friction, making longer travel, heavier loads, and faster speed applications possible

  • Reduce friction and travel more than 2,600 ft at speeds up to 32.8 fps

  • Drive power is reduced by more than 25%; resistant to harsh conditions, such as thick dirt

High-efficiency motor

The HP Series motor combines ac-induction motor technology with that of brushless permanent-magnet motors for a 50% reduction in frame size and weight, and 80% energy savings.

Features & benefits

  • Lower stator currents generate lower losses that reduce winding and bearing temperatures; low temperature rises eliminate the need for a cooling fan and allow higher running speeds and longer bearing life

  • For continuous-duty applications

  • 0.75 to 2.2 kW single-phase power ratings and three-phase supply versions of 0.75 to 22 kW in both 50 and 60 Hz applications; available with built-in drive or as a standalone unit
