Abstract: A device for protection and handling of electric feed cables (20-20?) for mobile use, especially for a mobile device (26-26?) for lifting and moving loads such as cranes, bridge cranes and the like installed along harbour docks. The device includes a mobile frame (10-10?), made of metal or other suitable material, provided with a central tower (30-30?) connected to said mobile device and with opposite arms (32-32?), arranged in alignment on a part of a trench duct or raceway (12-12?) buried in the ground with an open top substantially aligned with the surface level (14-14?) and screened by a flexible tape (16-16?). At least one of the opposite arms (32-32?) is provided with structure for lifting the flexible tape (16-16?), arranged at the top and/or at the bottom of the tape, and structure for guiding and centering the frame (10-10?) in cross direction relative to the raceway (12-12?).
