With a feeding roller 75 cm in size!
The optimised feeding system and a large and aggressive feeding roller allow convenient introduction of material within easy reach of the chipping knives.
Increased flow capacity, higher quality of wood chips
Its split and large screen element accelerates the material drainage after the chipping process, also increasing the flow capacity of wood chips. The minor friction also reduces the content of small particles leading to a higher quality of wood chips.
The large, low-wear blowers with a diameter of 1.55 m allow gentle ejection of wood chips to a wide range.
Accurate stream of chips
Ejection at a level of 5.2 m is ideal for feeding high-levelled trailers and containers. It is hydraulically adjustable in level from 2.6 to 5.2 m. By using the optional flap above the stream, the chip spout can be diverted upwards or downwards to use the space of the applied storage area to full capacity.
Fine or coarse chipping
The new multi-purpose chipping rotor is smooth-running and energy-saving by construction. The robust chipping knives or the optional blade system produce as well precise and fine as coarse chips for industrial furnaces – depending on applied knives or screen size. If you consider retooling, you can switch also belatedly between robust chipping knives and the fast-adjustable blade system.
Knives safeguarded against foreign objects
The patented knife fixing prevents or at least considerably reduces damages to the mechanism caused by foreign objects.
The standard hydraulic locking of the feeding hopper is being handled conveniently from the operator’s remote controlling unit. Reverse automatic and easy adjustment of feeding aggressiveness prevents the unit from overcharging.
Flexible Z / ZK variant
The adjustable chassis for a simple composition with or without crane and simple switching between suspending and coupling distinguish the Z / ZK variant as a flexible device.
