Agile and powerful, the PTH 1400/820 Allroad by Pezzolato

The new model of the Cuneo brand following a debut at EIMA, is arriving for a tryout in Paris, a new self-propelled drum chipper is built for great maneuverability in the field and heavy duty operations

Pezzolato’s brand new PTH 1400/820 Allroad self-propelled drum chipper, unveiled last November at EIMA International, is now headed for the  Sima Agribusiness Show in Paris. On the runup to the opening of the exhibition, the manufacturer located in Evie, near Cuneo, reported the details of the new compact drum chipper built for work in the field requiring excellent maneuverability. In a technical communique, Pezzolato said, “Compared its direct chipper competitor, the PTH 1400/820 Allroad has various axles up its sleeve so that it can travel on public roads, something a forestry forwarder cannot do, and can work directly in the field which is not accessible for a truck.

Moreover, the change from a road configuration to the field can be done in less than two minutes with a coordinated maneuver sequence performed by the operator by pressing one single button. With a single command the user can manage the opening of the feeding inlet, raise the discharge chute, extend the crane and lower the support legs.”

Pezzolato conducted trials with the PTH 1400/820 Allroad and a chipper of the same power loaded on a 6X6 truck and a two-axle trailer loaded with chips trailed by an agricultural tractor.

The the Allroad very seldom got stuck but on various occasions rescue work was required to get the 6X6 truck out of the mud.

On fuel consumption, it resulted that there was a great advantage using the Allroad fan for discharging the chips with continuously variable speed control. Thanks to this method, the operator can select maximum speed in all conditions when the distance of the discharge of chip is increased, for example with green materials which tend to clog up or a tipper has to be refilled from the bottom up due to a problem of space.

Speed can be adjusted to a minimum to reduce consumption by 15% for chipping especially clean materials. 

The Black Box central processing unit acquires data on the machine parameters and the engine and transmits engine data and monitors the work and operations of the chipper. Another strong point for the PTH 1400/820 Allroad, Pezzolato also reported, is that the chipper can be supplied with a collapsible counter-blade mounted on a running slide and secured with adjusted shear bolts.

Whenever a hard body accidentally enters the chipper, the bolts are sheared and the counter-blade falls down, so that the foreign body exits before causing damage.
