A finger car is one of the main components of a concrete block plant, because it transports the production pallets with the fresh products into the drying chamber and feeds production pallets with the hardened products to the lowerator and is thus a central interface in the production plant. The malfunction or failure of a finger car automatically leads to loss of production. In most cases a finger car has an independent controller, whereby old controllers are often equipped with a technology whose availability is no longer guaranteed. The drive concept in this case is almost always based on dc motors or oil motors.
