• Branches can be fed as well

Ergonomic safety circuit according to EN with circumferential safety bar

All directional functions of the feed rollers can be controlled directly via the operator handle: Feed, stop, and reverse can be adjusted easily from any operator position. Without additional operating elements, such as buttons.

Large aggressive feed rollers

JBM wood chippers are powerful and voracious. Whether knotty material, large amounts of shrubs, thick trunk diameters, fir branches or even wet material: A JBM draws in everything. Evenly and safely.

Your benefits:

• High hourly throughput
• Ergonomic feeding
• Fault-free working
• High occupational safety

Encapsulated feed system

The encapsulated feed system of JBM wood chippers avoids material discharge from the feed area. This avoids contamination of the wood chipper interior or of the street.

Roller wrapping protection

Wood chipping – without problems would be the best! The roller wrapping protection prevents shrubs from wrapping around the feed rollers. Your guarantee for continuously aggressive, fault-free feeding.

Horizontal feed rollers

Every JBM features horizontal, parallel-guided, hydraulically driven feed rollers. For a good reason:

• Tight grip of the fed material
• No uncontrolled knocking or side movements of the material
• A plus for your occupational safety
• Sustainably even and aggressive feed

Hydraulically driven conveyor belt

Welded gripping feed rollers

Some chipper dump trailer combos can also be equipped with gripping feed rollers. We will be happy to advise you.

Hydraulic cutting length adjustment with hydraulic turning system

JBM wood chippers are equipped with a hydraulic, continuously adjustable cutting length adjustment by default. They produce wood chips in the length range of 0 - 25 mm. and can ideally use the available chipping capacity.

Continuously adjustable cutting speed

Thanks to the continuously adjustable material feed speed, the required cutting capacity can be adjusted to the material to be processed. This creates even more flexibility.

Material flow-optimized hopper design

Fault-free, efficient operation is a must during chipping. JBM wood chippers offer an optimum material flow across the entire cutting process. All components have proven themselves over many years and are matched to one another:

• Optimum hopper loading height
• Hopper size
• Hopper shape
• Feed quality (aggressive, even, fault-free)
• Optimum cutting process without risk of clogging in the area of the chipper disks
• Optimum powerful discharge

Optimum loading height

All chipper dump trailer combos offer an optimum loading height. You can feed the materials to the feed rollers without problems. Upon request, we can customize the loading height to your specifications.

Stable blade mounting system and massive chipper disk with reinforced blade insert

The cutting area is one of the core components of every wood chipper. JBM machines offer a stable blade mounting system and a massive, generously dimensioned chipper disk with reinforced blade insert.

Generously dimensioned chipper disk

JBM attaches particular importance to a generous dimensioning of the chipper disk in all model series. The large chipper disk diameters allow a large discharge range of the chipped material. The higher disk thickness ensures high inertia and high stability of the chipper disk at the same time. This way, temporary load peaks are compensated in the case of limited engine power.

Chipper disk reinforcement

Thanks to additional reinforcements in the blade area, breaking of the chipper disk can be prevented even under extreme loads.

Chipper disk dynamically balanced

To ensure smooth, low-vibration operation of JBM machines in all speed ranges, JBM chipper disks are dynamically balanced.

Powerful discharge with large discharge range

Particularly generously dimensioned discharge for fault-free working.
In connection with an optimum chipper disk speed, a large chipper disk, and generously dimensions discharge blades, you benefit additionally from large discharge ranges of the chipped material.

Quality blades made of specially heat-treated steel

High service life due to the selection of special alloy steels in connection with special heat treatment. We only install quality blades in our machines. Your advantage:

• Avoids blade breakage, for high service life and short maintenance times
• Outstanding quality of the JBM blade system thanks to optimized raw material selection in connection with a hardening process optimized for the application case
• Extremely long service life and thus, low maintenance and blade costs per chipper hour
• Low, specific fuel consumption
• Blade costs reduced to a minimum

Continuously adjustable cutting system

Blades can be sharpened several times resulting in wood chipping with minimum blade costs.

Counter blades can be used 4 times

Reusable counter blades reduce blade costs.

Vertical counter blade on the inside

The side walls are subjected to particular wear due to the cutting process in their proximity. The side wall protection protects against wear and significantly contributes to value retention of a JBM wood chipper.

Over-dimensioned main bearing

Stable mounting system generously dimensioned. To ensure that unexpected additional loads do not leave permanent impairments.

Additional wrapping protection for main bearing

Additional wrapping protection acting as sealing system at the same time. The wrapping protection protects the rear main bearing from foreign objects penetrating, such as plastic ropes.

Discharge chute can be swiveled according to GS standard

If needed, the discharge can be swiveled as well so that the wood chips can be purposefully placed. This means simpler material disposal and additional occupational safety.

Silent discharge chute

Silent discharge chute with integrated noise protection: another contribution to reduced noise emission of our wood chippers.

Perfectly shredded wood chips for covering plots or heating systems

Ergonomic safety circuit according to EN with circumferential safety bar

All directional functions of the feed rollers can be controlled directly via the operator handle: Feed, stop, and reverse can be adjusted easily from any operator position. Without additional operating elements, such as buttons.
This way, you can operate your JBM easily, safely and ergonomically. The feed rollers are reliably and durably controlled as well.

Electrical control via sensor button

Upon request, we configure our machines also with an electrical button control.

Safety-related requirements according to GS and EN standards

JBM chipper dump trailer combos offer maximum personal protection during operation as well as maintenance. Our machines are designed according to the high requirements of the GS standards and relevant regulations of the employers' liability insurance associations.

Hydraulic feed control with cutting length adjustment

JBM wood chippers are equipped with a hydraulically adjustable cutting length adjustment by default. This way, you can adjust the desired length of the chipped material continuously.

Anti-locking system for automatic roller control

The anti-locking system continuously monitors the cutter disk speed. If overloading of the wood chipper is imminent, the material feed is stopped automatically by the feed rollers and automatically restarted. This enables an automatically controlled material feed. The machine cannot be overloaded or clogged. The work sequence is optimized and the operator relieved.

Hydraulic roller opening for easy feeding of large trunk diameters

Using this function, the wood chipper can be easily fed with short, large-diameter pieces of wood.
For this purpose, the opening area of the feed rollers is increased to more than 100 mm. This is another contribution to ergonomic loading while increasing occupational safety.

Combination hydraulic control block for anti-locking system and integrated roller opening

The compact control block combines the standard hydraulic actuation of the feed direction with continuous feed speed control with the hydraulic roller opening and integrated anti-locking system.

Designs according to the GS standard

JBM wood chippers offer maximum personal protection during operation as well as maintenance. For this purpose, our chipper dump trailer combos are designed according to the high requirements of the GS standards and relevant regulations of the employers' liability insurance associations.

Pressurized hydraulic hoses with burst protection

Enjoy additional safety: All pressurized hydraulic hoses of a JBM are additionally wrapped in a strong burst protection fabric.
Hydraulic fluid suddenly escaping due to bursting hoses represents an extremely high risk to human health. We here at JBM understand our responsibility as manufacturer. We are more than happy to offer this protection, which should be standard everywhere.

Double-walled steel housing for chipper disk tunnel

What happens, when stones or metal parts are fed to a wood chipper by mistake? And at the high speeds typical for wood chippers?
Tremendous load would be applied to materials installed in the turning circle of the chipper disk. The cutting system might be damaged or even destroyed. In the worst case, material could exit uncontrollably from the chipper disk housing.
To ensure that such a danger potential does not exist in the JBM wood chippers, we do not only comply with the legally prescribed material thickness, our upper and lower chipper disk tunnels are designed with double walls.

Safety operator handle and feed hopper dimensions according to EN 294 and EN 13525

Compliance with the safety clearances and installation of the safety operator handle according to the current safety standards enables easy and safe operation.
The circumferential safety bar is the most effective protection against the operator being caught unintentionally by the feed rollers: If reaching into the hopper area too far, the operator moves the operating handle with his legs or arms into the stop or reverse position.
All functions, such as feed, stop, and reverse, can be easily operated from any operator position.

Gas pressure spring for upper tunnel

The massive upper tunnel can be easily opened with the help of a gas pressure spring. This allows quick, easy, and safe access to the cutting system.

Silent package

JBM chipper dump trailer combos feature low-noise designs. Respective structure-borne sound emissions are reduced through additional coating systems specifically developed for our application case. A pleasing contribution to noise reduction.

Silent discharge chute

The integrated hard rubber strip in the silent discharge chute significantly reduces the sound emissions occurring in the area of the discharge chute. Another contribution to noise reduction during wood chipping.

Transparent safety curtain

The transparent safety curtain prevents uncontrolled ejection of fed material from the hopper.

Quality blades

Special blade steels in conjunction with a special hardening process ensure high service life. Blade breakage is avoided at the same time.

Good access to the cutting system for adjustments and replacements

Adjustments and replacements on the cutting systems are easy and quick thanks to the wide-opening upper tunnel.

Gas pressure absorbers

The massive upper tunnel can be easily opened with the help of a gas pressure spring. This allows quick, easy, and safe access to the cutting system.

Duo lubrication system

Using the Duo lubrication system, you can grease difficult to access lubrication points quickly and easily. For example, the rear main bearing or the mounting points of the lower rollers.
