First Jenz chipper truck to Estonia

The Volvo brand is particularly popular in Scandinavia and the Baltic countries. A request for a chipper on a Volvo chassis is therefore not really a surprise. JENZ now followed this customer request and delivered the first chipper truck HEM 583 R to Estonia.

Germany-based chipper manufacturer Jenz GmbH has revealed that it has sold it first truck-mounted chipper to Estonia. According to Jenz, the Volvo Chipper Truck especially fulfils the specific customer needs in the sparsely-populated Scandinavian and Baltic countries.

Sometimes the working sites are a long way apart. The drivers are often on the road with their chipper trucks for a considerably longer period and often have to overnight in them thus the comfort provided by the driver’s cab is much more important in these cases. In addition, the HGV should at least be partially usable on uneven roads, which isn’t necessarily the case for most HGVs with long-distance driver cabs.

Volvo scores points in both cases because the Volvo FH in question is also available with a medium-height chassis as a series production. This is not the case with other manufacturers. The customer ordered the FH 16 with 550 hp and a 4-axle tridem chassis as a chipper base.

With the Volvo chipper truck, we have to take power off at a different location along the drivetrain in comparison with the MAN chipper trucks we used as standard up to now. The Volvo does not have a front wheel drive and only drives the first two rear axles. For this reason a power divider was used in order to route the power flow either to the chipper or to the rear axles. All the drive components are also designed for this purpose as “heavy duty” components, explained Stefan Müller, Research and Development Manager at Jenz.

The wheelbase is slightly longer than the standard chipper truck due to the drivetrain. However, Müller considers this an advantage because both the first and last axle are steered. This means that the HGV is still very manoeuvrable despite its four axles.

With one axle at the front and 3 at the rear we still have sufficient reserves in terms of weight and length. This means that other chipping units, for example the HEM 593 R or the HEM 821 R, could also be built on without requiring special approval, said Müller.

The first customer decided to take a chipping unit with a medium power class, the HEM 583 R. The objective was to build the machine on as simply as possible.

That’s why we decided to orientate ourselves on our power takeoff machines and we also applied the pump distribution transmission we use in our power takeoff machines. That is something which has established itself successfully over many years of practice. Apart from this, the construction ensures that all the hydraulic components in the chipper are as far away from the diesel motor heat source as possible, said Müller.

The alternative concept definitely results in savings of work time and hotel costs under the corresponding deployment conditions, and at the same time, it achieves maximum comfort for the driver.

It is completely different to the previous chipper trucks, and it might result in overhauling the question: crane cab or driver’s cab with mowing window, ended Stefan Müller.
