Biber 7

Sophisticated technology – high-performance and smooth runningThe high centrifugal mass of the Eschlböck chipping drum, with its 8 knives offset in pairs, guarantees smooth running and a relatively low power requirement. The electronic feed control that comes as standard enables you to work continuously, even with a small towing vehicle, and increases throughput. The powerful hydraulic system (on the Biber 7 plus extra power comes as standard) and the robust V-belt transmission make for a powerful in-feed system. In addition to the sturdy knife arrangement, there are also other quick-change blades available for chopping soft wood and shrub clippings.

Anti-foreign body shear pin safety device

Foreign bodies that have been forgotten in the stored timber, such as tools, can easily be overlooked when loading by crane, and can finish up in the wood chipper. Thanks to the new patented anti-foreign body shear pin safety device on the knife mounting, minor damage can often be avoided or at least reduced and the cost of repairs cut.

Big feed opening and chain belt in-feed

The chain belt in-feed makes it easy to load anything from whole trees to short logs and bark. The new and conveniently large feed hopper is fitted with state-of-the-art safety devices.

Biber 7 plus – safety devices for loading by hand or crane

Without having to dismantle anything, the manual gearshift is protected simply by putting the crane extension hopper in position. When loading by crane, all functions can be conveniently controlled by wired remote control from the towing vehicle. Biber 7 plus offers the convenience of the big machines.

With interchangeable screens for accurate chip sizes

Having interchangeable screens means that different chip sizes can be accurately produced in accordance with Austrian standard 7133 and EN 14961. The two feed screws and the powerful blower give the wood chips a greater discharge range.
