LINAK linear actuators in New Holland combine harvesters

Ease of integration and multiple control options make electric actuators an ideal choice for New Holland combine harvesters.

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.

Michaël and his team investigated the best ways to make a combine harvester even more efficient, environmentally sound and comfortable for the operator. Electric actuators helped achieve this goal.

Precise machinery settings and positioning are important for achieving the best possible yields. LINAK LA36 electric actuators can provide precise operation much better than hydraulic systems in which feedback and positioning require considerable technical complexity.

Integration into the bus controls is easy with feedback on position provided as either an analog or a digital signal.

New Holland combines offer the optional Opti-Spread straw spreader which is attached behind the straw chopper. Electric actuators allow the farmer to control the width and direction of straw ejection. Two powerful spreader discs are set with the aid of LINAK LA36 actuators.

'We use electric actuators very frequently because, in contrast to hydraulic systems, there is no risk of leakage,' notes Michaël Carpentier, CNH.

LINAK LA36 actuators meet the demands for robustness and stroke strength. Its robust aluminum housing and high protection rating (IP66 dynamic, IP69K static) enables it to perform a wide range of tasks in multiple agricultural applications.

Robustness is not merely protection against external factors, such as dirt, dust and water.

Operational reliability is key for surviving impact and vibration. For example, the LA36 adjusts the sieve setting for harvesting on a hillside. Depending on the slope, the actuator induces a side impact of sieves, so that threshing can always take place on even loaded sieves.

'This actuator is constantly exposed to vibration,'states Michaël Carpentier.'It has to continue to operate safely and problem-free despite this vibration.

LINAK spends a great deal of time and effort during development on testing actuators in a variety of operational environments. They must withstand cold, heat, wet chemicals and knocks. Only after passing the tests are they allowed to go into production and finally to the customer.

Depending on the model, up to 13 actuators may be fitted to a combine harvester.
