In this series of articles, we will be sharing exclusive coverage from KWF Tagung 2024. 

CONTROL was very much the buzzword on the stand of Dutch/German attachment manufacturer Vosch, which placed its 50 Series grapples front and centre. Featuring a large demonstration area (shared with partner Fuchs, which was showing off its MHL420), both the new RSG 1650 WS and RSG 1650-7T VC were put to the test – and certainly impressed. 

Equipped with the “innovative Vosch Control hydraulic system”, the grapples’ own valve block operates from a CAN bus control link directly from the carrier’s electronic systems, meaning the common problem of adding a third hydraulic circuit to the machine is avoided.

“The main difference is the control system; how you control the grapple,” said CEO Aloys van Osch. “In the old days, we needed three hydraulic lines. Now we only need the hammer line. We run all functions proportionally off the grapple, and more functions on the saw bar. We can cut off a limb, move the saw in and out, all without moving a chain. 

“While we work with the hammer line, we have more oil flow available for our rotation function. We have more speed and more momentum. 

“It’s immense, and no other provider can provide that.” 

While both of the new grapples have been designed for 15- to 21-tonne excavators, the RSG 1650-7T VC weighs a touch more (at 1,150 kg) and boasts a maximum cutting diameter of 80 cm. 

“It has been very positive,” said Aloys of the grapples’ reception. “The last two years we implemented the new 50 series on customers who we know and are experienced. We’ve fine-tuned it during that time; and you can see the results.

“We are for the professional entrepreneur. With this control system, there is no other on the market who has something similar. Even now the new generation working with a tiltrotator, our control system can work with the main tiltrotator systems.

“You don’t need another control system, which can be expensive.”

Working alongside UK dealer Richard Court Forestry Engineering, Aloys is hopeful the new grapples will prove a hit, especially as the forestry market recovers. 

“We are in a growing line, slow and steady,” he said. “That’s important for me. This year, everyone is waiting because of the economics. But mainly people are interested, and have projects going. After the summer, it will be on a normal level again. We had it too good the last four years.”
