Cable Reel Cart mounted on truck or trailers, with capacity of 350 meters. The cart has a diesel power unit, which feeds the rolling system, giving it absolute autonomy (only needs to be moved by another equipment). It has a guiding wire pen up the cable to the railing, a reeling system where the spool is rotated by a motor to deliver or collect the wire, a system for loading and unloading of the spool, and a host cable system to orderly lay the cable. This equipment, unlike previous ones, tend cable on the way and then returns to the reel by the cable-guide pen. All these tasks are performed by remote control.
