Case story

AVR means efficient and comfortable harvesting

Belgian company AVR has been developing potato harvesting machines since the second half of the 20th century.

In the past, potato harvesting required a great deal of manual labour. Currently, the four-rowed self-propelled Puma 3 harvester from AVR carries out the complete potato harvest with impressive efficiency.

Puma 3 makes use of actuators from LINAK for many different tasks.

"Electric actuators are becoming ever more important," says Stefan Top, Managing Director of AVR. "They are simple to apply and easy to integrate."

He especially values the functional reliability of LINAK actuators.

"The actuators have become increasingly more robust in recent years, and this is very important to us."

Larger often means more complex
Machinery is becoming larger, more complex and more efficient. The tasks and demands placed on actuators are becoming ever more stringent. Electronics and communication with various BUS systems are playing a progressively more important role.

In 2001, AVR introduced the first potato harvester outfitted with a CAN bus system.

"With the help of numerous technical innovations, such as the introduction of the CAN bus system, we have succeeded in optimising the potato harvest and making it more efficient," says Stefan Top.

The integrated electronics and the multiple options for position feedback make it possible to integrate electric actuators simply and inexpensively in the machine's BUS systems.

"The components must communicate perfectly with each other," Top insists.

For example, use is made of the LINAK actuator LA35. Hall sensors in the actuator relay the position of the spindle to the entire system.

The driver can configure and position the rollers and cleaning devices of the harvester perfectly from the driver's cab.

The are several reasons for using electric adjustment
Besides the precise configuration of machine components, such as the deactivation of individual rows in a planter or the repositioning of cleaning rollers in a harvester, the improvement in operating procedures is also an important factor.

It is now crucial that the farmer concentrates on important things. More and more parameters must be taken into account when planting, fertilising and harvesting.

Electric actuators are implementing more and more adjustments and settings for individual components.

The operation of machinery is growing in complexity from generation to generation.

Stefan Top expects electric actuators to take over other tasks involving AVR products in the future. AVR already uses a wide variety of LINAK actuators. Besides the LA35, use is made of LA30, LA23 and LA12 actuators.
