Junkkari HJ320
Junkkari HJ320 is a powerful and compact tractor mounted chipper for contractors. Its extremely sturdy frame is equipped with a flange, to which a crane can easily be mounted. The chipper is available with a conventional infeed chute or a infeed conveyor.
Optimal feed angle for high output
The heavy-duty disc of the HJ320 chipper is equipped with four knives which makes it a highly powerful machine in its size category for contractors. The feeding angle of 60 degrees to the disc reduces the power demand and enables high production. The blades are steplessly adjustable for different chip sizes. Under optimal conditions, the HJ320 chipper can chop up to 80m3 per hour.
Crane-mounted contractor chipper
The HJ320 model with crane infeed chute has two horizontal feed rollers. Alternatively you can choose a carpet conveyor to replace the lower feed roller. The length of the in-feed conveyor is 150 cm. For both versions, the wood must always be fed by a crane loader.
Infeed chute
Optimal infeed chute for the loader
The infeed chute is wide and sturdy. A no-stress rotation guard as standard ensures smooth operation. If the tractor rpm drops, the feed stops, the rollers retract the wood away from the blades and automatically resume feeding when the rpm rises back to the working level.
The model with the infeed conveyor has a longer chute. The length of the conveyor is 150 cm. The HJ320 chipper must always be fed with a crane loader.
Blade disc
Uniform quality wood chips
The chipper’s disc is equipped with four steplessly adjustable blades, allowing you to precisely determine the size of the chips. From the blades, the chips are transferred to the peripheral blower blades of the disc, where they are crushed, and the blades blow the chips through the chute to the desired location. Optional brush blades are available for the disc. Additionally, the chipper can be converted to a two-blade setup with optional cover plates.
Control unit
Wizard C+
Chipper functions are controlled by the Wizard C+ controller and the foot pedals that are included. The controller display shows, among other things, the rotation speed of the disc. Functions such as horn and feed are controlled by the controller with easy to use switches. If the operator’s hands are on the crane controls, the chipper feed and top roller can be controlled by foot pedals.
Accessories
Adjustability with blade options
The HJ320 chipper is available with an optional brushwood chipper kit, which ensures a high quality chip production even from smaller wood material.
The optional cover plates allow the blade to be converted to a two-blade model, which is ideal for use with a less powerful tractor.
