JENZ expands its sucessful Chippertruck range with the development of this new chipper model HEM 540. This new development which will offer increasing number of uses for the machine operators. In comparison to the bigger Chippertruck models, this HEM 540 scores with a lower puchase price and highly efficient running costs.

To stick to the maximum permissable weight of 18,000 kg, a new range of HEM 540 was developed. With an infeed width of 790 mm and a max infeed height of 650 mm this model defines its class anew and sets new benchmark for efficiency. The base of the new Chippertruck HEM 540 R is the MAN 18-360 4x4 which, unlike other tuck based chippers, has only two axles.

The development of the new chipper unit resorted to the tried and trusted components of the known model range HEM 500. The new HEM stands out due to its huge screen area which is an optimum requirement for a high throughput rate. The big screen area open hydraulically and ensures quick and simple maintenance access. The screen basket is changed using only minimal assistance, without tools, very comfortably. This technology has been taken over from the bigger mobile chippers. On top of that, the HEM 540 R-Truck has an optimised infeed table, which is particularly suited for bulky materials, i.e. shrub cuttings, with its funnel-type shape directing input material straight towards the infeed rollers.

The drive has a performance of 360 hp and maximum torque of 1,800 Nm, akin to the level of performance of todays heavy duty tractors and offers the best possible connection between performance, low initial outlay and efficiency (running costs). The new machine´s performance is very convincing: more than 100 loose cubic meters can be processed per hour. Maximum permissable diamter for hardwood is 42 cm and soft wood 56 cm.

The MAN TGS 18.360 4x4 truck is equipped with all-whell drive, differential lock and special tyres for maximum traction - on top of that it meets current Euro 5-Norm. A roomy driver´s cabin with special windows to allow for better working conditions and offer a maximum of comfort whist working.

The advantages of the new Chippertruck HEM 540 R-Truck are obvious during daily use - especially the smalles dimensions and the capability to move easily between places of work stand out. "Our experience shows that over 50% of a working day are spend transporting the chipper from one job to the next. To use the machine to its best advantage, it is imperative to keep those transfer times as short as possible," explains Stefan Müller, construction designer. With a maximum speed of 80 km/h is can use German motorways and is therefore able to go from one job to the next without much effort.

Even smaller jobs in the private or communal sector will become more interesting whereas in the past those would be too expensive due to long journey times. "In the past, when journeys between jobs are between 30 to 40 kms but the jobs only take a couple of hours, contractors had to decline. Running costs are considerably lower with the new Chippertruck so those jobs now become more feasible," explains managing director Uwe Hempen-Hermeier. New jobs opportunities open up such as landscape conservation jobs along roads and motorways. Materials collected there can now be used cost effectively by communes/councils for energy use.

Next to the original JENZ Chippertruck which consists of an MAN chassis and the HEM 582 R, JENZ now offer a bigger version of the successfull machine. The new three axle truck MAN TGS 540 6x6/4 is now available with the bigger chipper unit, HEM 820 R. This chipper unit has a rotor measuring 1,040 mm in diameter and enabling the machine operator to process wood up to a diamter of 800 mm.

Typical advantages of the Chippertruck remain. The drive engine is also used to power the chipper. This design keeps the total weight of the truck (including a crane) low at 27 t. This means increased mobility and fuel efficiency when moving from one workplace to the next. The chippertuck can even travel at 80 km/h (50 m/h) (suitable for driving on German motorways which have a "minimum speed limit" of 80 km/h). A self steering rear axle keeps the turning circle at a 17,6 m. This also means that the Chippertuck manoeuvres easily off road.

The hydraulic infeed table lock and the tool free screen change using hydromechanical system of the screen mean short downtimes and quick tool changes. The cover for the belt can be openend hydraulically by the turn of a switch from the driver´s cab.

The comfortable swivel chair, two ergonomical joysticks and a soundproof cab offer excellent working conditions that meet even the highest demands in comfort, ergonomics and safety. Modern easygreen controls enable optimum machine operation and highest output whilst used continually.

The JENZ Chippertruck is being manufactured in close relation with MAN. In this sector, it is the only authorised conversion of transmission and driver´s cabin with harvest windows in the side and rear that is professionally done at the MAN factory. Most important is the reliability of the drive train during everyday use. It is capable of transmitting 8,000 Nm, the most powerful drive train in its class. Its success is proven by its hight resale value on the second hand market.
