LINAK LINEAR ACTUATORS - IN NEW HOLLAND COMBINE HARVESTER

New Holland uses electric actuators in combine harvesters. Alongside ease of integration, there are in particular the multiple options for control that favour an electric actuator. Adjusting, positioning, moving - electric actuators perform a range of tasks in a combine harvester. And, this will certainly increase in the future. Michaël Carpentier, Product Development Manager at New Holland in Zedelgem, Belgium, is convinced of this fact. He and his team investigate the best ways to make a combine harvester even more efficient, environmentally sound and comfortable for the operator. The use of electric actuators is important in this regard. Precise setting of the machinery is especially important for achieving the best possible yields, and precise positioning plays a key role here. LINAK electric actuators LA36 can provide precise positioning. This task is performed considerably better than hydraulic systems in which feedback and positioning require considerable technical complexity. Since feedback on position can be provided as either an analogue or a digital signal, integration into the bus controls can be performed without difficulty. A major application for an electric actuator in a combine harvester involves, for example, a straw distribution system. On request, New Holland combines offer the Opti-Spread straw spreader, which is attached behind the straw chopper. The farmer is able to control the width and direction of straw ejection. Two powerful spreader discs are set with the aid of LINAK actuators LA36.
