The CRH450 equipment manufactured by Fma is mounted over a truck with a cable reel system with a capacity of 450 meters. This truck has a work station, with a rotating reel driven by a hydraulic motor, to deliver or collect the cable. At the rear it has a positioning arm for the cable. At the same time, the workstation can rotate in the horizontal plane as it is mounted on a turntable.
This model can have a second reel of 450 meters, located next to the truck cabin, in order to double the capacity of the original cable, becoming a CRH900 model. Between the two reels, there is an articulated crane, which is used to exchange the reels between the two stations or simply to raise and lower the reels onto the truck. The workstation has a cabin for an operator to handle the cable. However, the system has a remote control so that the operator can control the equipment.
