BUNK LOAD SYSTEM FOR A FORESTRY WORKING VEHICLE

It is disclosed a bunk load system (10) comprising a load bunk (20) with support arms (30), the support arm (30) having a horizontal (31) and vertical section (32), the sections being adjustable by hydraulic actuation, sensors (40), detecting the position of each section of the load arm, a load height detection system (50), comprising a crane (60) adapted for loading and unloading the load bunk (20), adapted to detect a vertical position of its crane tip (70) in relation to a bottom surface (80) of the load bunk (20), adapted to detect a loading and unloading operation, a controller (90), adapted to receive input from the sensors (40) of the load bunk (20) and receiving the input from the vertical position of the crane tip (70), comparing the input values, and in case the crane (60) is detecting a loading operation and the loading height is at a limit of the load bunk (20), sending as an output a signal to the hydraulic actuation adjusting the height of the vertical section (32) or the length of the horizontal section (31) of the load bunk (20).
