Electrical or electronic boards are the brain of the tail lift. This is where the input signals are processed and electrical impulses returned to the output. Each manufacturer has created several types and for the most varied applications, obviously updating them over time according to the development of technologies. In some cases we have simple green boards with tracks and cube relays mounted on top, in other cases real really complex electronic boards. In more recent years, they are often supplied protected by a layer of resin. Being mounted on vehicles and often in positions where they could be affected by atmospheric agents, that type of protection guarantees greater durability and resistance. It is possible to find them inside the control panels, fixed in the rear casing, as well as inside the hydraulic power units. Finally, some manufacturers house them in the tubulars of the main frame that supports the tail lift.
