suspension, spring-loaded, air braked system taken from the testing centre, 560/45 R 22.5 tyres are installed. The drawbar with variably adjustable trailer heights is a fresh addition. The drawbar was specially developed for the HM 8-400 KFL and is now also suitable for other chippers. “The robust, clear and easy-to-maintain Heizohack wood chipper HM 8-500 KFL is the optimal machine for the start of professional wood chip production,” the manufacturer claimed.
Innovations on the Truck Chipper HM 14-860 KL
The engine on the latest model HM 14-860 KL has been upgraded to the more powerful Arocs 3353 AK, 6x6 with an output of 530 hp (390 kW)
For more than 36 years, Heizomat has produced high quality wood chip boilers in Bavaria, Germany. To date, over 35,000 heating systems in the 15kW to 1,000kW power range have been installed worldwide. After the first woodchip heating systems had been sold, Heizomat discovered that the disc chippers currently available in the marketplace did not produce the required uniformity of chips. From this necessity arose the idea of developing a chipper that produces even chips. This was the birth of the Heizohack drum chipper.

Almost 30 years ago, the first Heizohack was launched into the market. In the meantime, the chippers have become the second pillar of Heizomat. Almost a third of the annual turnover is now generated by the extensive Heizohack product range.
HM 8-500 KFL: an ideal entrylevel machine for contractors The Heizohack product range has been expanded to meet multiple customer requests and today Heizomat is pleased to introduce the new HM 8-500 KFL. Based on the proven singleaxle chassis of the HM 8-400 KFL, the HM 8-500 KFL can now also
be equipped with a loading crane on the drawbar. The handling and operation of the loading crane has been significantly simplified compared to the previous machine, where a 6.7 m loading crane was built behind the wood chipper on an A-frame. The Palfinger Epsilon C45F84 with 8.4 m offers considerably more range and is used in combination with the four-finger energy log grab, Heizogreif HG 1000. This grab has been specially developed for the ‘small’ cranefed Heizohack wood chippers, HM 8-400 KFL and HM 8-500 KFL. With an opening width of 1,021 mm, it is ideal for feeding the HM 8-500 KFL.
Wood waste such as slats, edged pieces, pieces of wood, rinds, branches but also whole tree trunks can easily be processed into high-quality wood chips with a feed width of more than 700 mm and a pull-in height of 800 mm. Whole trees can be processed up to a diameter of about 500 mm. Powered by a 10-groove V-belt countershaft, two power bands transmit power to the chipping rotor. The rotor is equipped with eight quick-release blades. Built-in special sieves ensure nearly slitherfree and homogeneous wood chips. Thanks to the large flywheel in the throwing fan, the machine can be operated with little effort, saving
fuel and making it tractor-friendly. The proven control unit HE002 is used as load and intake control. All other machine control units are also simple and like all Heizohack assemblies, are solidly constructed. A smooth but aggressive in-feed is ensured by the large upper feed roller, the powerful intake chain conveyor and the hydraulically driven feed roller, upstream of the infeed chute. An intake chain integrated in the infeed chute is available as an option. The wear plates installed in the machine are available both in a Hardox version and as an armoured version. With the 40km/h
The HM 14-860 KL truck chipper, introduced two years ago, has seen several improvements. The original carrier and drive vehicle Mercedes Benz Arocs, is now being replaced by the more powerful Arocs 3353 AK, 6x6 with an output of 530 hp (390 kW). Of course, this engine also fulfils the Euro 6 emissions standard. The slightly longer wheelbase now allows the installation of a larger (500 litre) diesel tank and can also take the capacity of the hydraulic oil tank, which has been increased to 500 litres. As an innovation, two hydraulic oil pumps are now being installed, which enable separate supply of the assembled loading crane and the oil circuit for the wood chipper via two separate oil circuits. Also new is the installation of
a robust safety glass pane from Kasiglas. The modified glass panel offers the operator the best possible protection and improved all-round visibility. Additional to the four LED headlamps on the driver’s cab, a new completely overrouted lighting package will now be installed on the outside of the truck cab. A light bar with 22,300 lumens on the cab front and a light bar with 3,300 lumens on the side of the cab rear wall ensure excellent illumination of the workplace. Two yellow front strobes integrated in the grille and a yellow warning light on the driver’s cab make it possible to secure the danger spots around the vehicle. The Ringfeder automatic towing hitch now has a 40 mm bolt diameter, and the two doubleacting hydraulic connections at the rear of the vehicle can now be used while driving, if required. As an option, the wood chipper can be equipped with a 700 mm telescopic ejection tower and the fan of the truck engine can also be equipped with reversible fan blades on request. The fan blades are automatically turned and clean the radiators by reversing the air flow. This fan system saves the need to frequently clean the filter pack whilst also reducing fuel consumption, since the truck engine operates at its ideal operating temperature.
