The German manufacturer of biomass heating systems and woodchippers Heizomat, has presented an entirely new product, the ‘Heizotruck ‘, which among other things is designed to move and power large mobile wood chippers. The Heizotruck is based on the twin-axle all-wheel drive chassis of the Mercedes-Benz Arocs 2051 4x4. It is powered by a 510 HP engine. The forestry version of the Heizotruck has the same modified user-friendly cab, with separate swivel seat and clear view rear window as the conventional Chippertruck from Heizomat. All necessary controls for the operation of a wood chipper are already integrated into the cab. The agricultural version of Heizotruck, however, is equipped with a large panoramic view rear window in the cab. In both versions, the rear PTO is driven by the NMV-drive (direct full engine power drive from the main gearbox). Due to the especially developed PTO drive there is a maximum torque of 3,800 Nm available on the mechanical PTO shaft. At an engine speed of 1,550 rpm a PTO speed of 1,000 rpm can be achieved at the rear PTO. This means that large power output can be obtained from the truck with low fuel consumption. The Load Sensing hydraulic system has a pump with an output of up to 250 litres/minute. The hydraulic outlet connections are mounted behind the driver’s cab as well as at the rear of the Heizotruck. In addition, there are five double-acting (DA) outlets at the rear, three DA outlets behind the driver’s cab as well as three DA outlets at the front mounting plate. The optional fifth wheel enables connection of standard fifth-wheel trailers. As a result this tractor unit has many uses, e.g. for the transportation of wood chips, for the maize harvest, etc. The Heizotruck and the high- speed tandem axle wood chipper Heizohack HM 14-860 KTL fit perfectly together. This is a large 26 in, 650mm diameter capacity chipper which fits perfectly behind the Heizotruck having excellent power and torque for efficient chipping. Depending on the set up of the chipper, the wood chips produced are suitable for all heating systems of private customers as well as for large commercial installations through to power generating stations. Due to the high output capacity of the LS hydraulic pump of the Heizotruck, the timber crane M80 F101 from Epsilon can also be used with maximum efficiency. The crane is still mounted on the wood chipper, as with previous versions. The operator’s distance from the truck cab to the in-feed hopper of the chipper slightly increases compared with a chipper driven by a tractor or a chipper which is firmly mounted on a truck. However, this gives a greater working range for the crane, which in turn means less moving along a stack of timber. For the crane-feed, a telescopic extension chute is available. The end piece of the chute can be extended hydraulically by 700 mm. This leads to better and more precise filling of trailers, containers and skips. With the special flap, which can mounted to the end flap of the chute, it is now possible to blow woodchips horizontally into lower buildings and chip stores etc. The chipper HM 14-860 KTL is one of the larger drum wood chippers with an infeed width of 1,215 mm and a maximum opening height of the upper infeed roller of 800 mm. End pieces to a maximum of 800 mm can be processed. Larger diameters can be split previously. Therefore a cone splitter with three motors can be fixed to the draw bar if required. The rotor diameter is 690 mm. Whole tree trunks with a diameter of up to 650 mm can be chipped easily. With the innovative multiple blade holder system, either quick change wear blades or chipper knives can be attached. For hard wood from a diameter of 400 mm, Heizomat recommends the use of chipper knives for this rotor type. The diameter of the upper in-feed roller is 800 mm. This large diameter and heavy weight in-feed roller makes easy work when feeding all types of new and waste timber into the chipper. Due to the arrangement of the 14 blades placed on rotor (or alternatively also the chipper knives), which spread over the entire feed width, Heizomat ensures a reduction of the power Energy in Balance with Nature Development and production of Heizohack-wood chippers since 1989 Quality made in Bavaria Heizomat GmbH Maicha 21 91710 Gunzenhausen / Germany Fon +49 (0) 98 36 / 97 97 - 0 Mail: [email protected] HM 6-300 VM Heizotruck + HM 14-800 KTL HM 14-860 KTL HM 14-860 KL International Forest Industries | APRIL / MAY 2017 57
