<p>Vehicle-assisted nailing and uncoiling devices for installing fence wire or similar, in particular for horizontal and vertical wire installation along one or several lines using tractor-type vehicules. The device comprises a T-support (A) connected to the tractor's elevating arm, a hinged arm (B) and a pantograph (Ac), which provides the nailing and uncoiling device with a mobile pivoting link in space. The axis of the nailing system is held perpendicular to the line to be laid. A jack (26), controlled by the vehicle, grips a hammer (24) by means of a locking device (29), compresses a capacity chamber (25) which produces the nail-driving energy. The cycle movement is provided by a proximity detector (27) located on the support. Nailing is accomplished by unblocking the mass and the jack in rearward translation. The wire is uncoiled under tension and guided. Application: agriculture, public and electrical works.</p> |
