The mobile chipper model 806.2 STC is a wood chipper to be used off road or at roadside for the production of fuel chips from forest residues. The chipper has a capacity to process full-length trees and logs up to a diameter of 50 cm (Max. 40 cm for hardwood) as well as brushwood.
Drum Chipper The drum chipper 806.2 is our latest developed chipper in the 800 series of mobile drum chipper. A chipper with aggressive infeed, closed drum for best chip quality, chip output by a chip accelerator and chip tube.
Mounting Frame
A mounting frame section with integrated mounting brackets for chipper and engine installation. Spring-loaded brackets for the carrier vehicle chassis allow certain independent movement of the chipping unit and carrier frame. A fold-down service platform is available for knife exchange and maintenance. A cage with a roof and hatches protects the diesel engine.
Chip Bin
To enable full volume during operation and at the same time enable low transport height, the chip bin is equipped with hydraulically foldable side panels. There is a rubber
containment curtain at the rear, that is elevated by the side panels. There are also notches for parking the crane into, or through the bin.
Dimensions: volume 21 m3, outer width 2.8 m.
High Lifting Dumping Yokes
High lifting and side dumping dumping yokes with 80 cm lifting height gives a displacement of the chip bin laterally to facilitate dumping into another vehicle or container. When tipping onto the ground it facilitates dumping the chips away from the machine. The dumping yokes are equipped with pre-routed lubrication points.
Diesel-engine Scania DC13 385A
A powerful stage IV engine with low fuel consumption. The engine is certified according to EU Stage IV. Complete installation includes side mounted ”side by side” radiator, transmission, starter batteries, fuel tank 350 L, AdBlue tank and exhaust system.
Power 368 kW, 500 hp.
Hydraulic System
The hydraulic system is a load sensing type and is powered by a variable displacement pump. The infeed, lifting and dumping of the chip bin is controlled by proportional valves to enable exact operation. The chip accelerator is powered by a hydrostatic pump which enables the accelerator to run at a constant speed regardless of the engine rpm. The cooler fans are hydraulically powered with the possibility to reverse for cleaning the cooler. There is an electrical pump be used when operating hydraulic functions with the engine switched off, for example when changing knives during maintenance.
Electrical System
Complete electrical control and monitoring system for the chipper unit. The chipper and engine functions are operated from the cabin from where the operator can monitor engine water temperature, water level, oil pressure, hydraulic oil level, oil temperature and hydraulic filter clogging indication.
There are also monitoring equipment and automatics for chipper safety functions such as anvil holder´s position and electronic infeed load control.
The system is monitored and controlled by a windows computer with color touch screen, control levers and sets of push-buttons for operating the chipper functions.
Emergency stop buttons are located and accessed from inside the cabin and on both sides of the chipping unit.
The 806.2 STC, our most successful mobile chipper concept, consists of a highly efficient chipper with its own engine, and chip bin. The chipping unit sits on a frame to be installed on an off-road vehicle such as a forwarder with crane.
To ensure the most efficient chipping operation the chipping unit is electronically and hydraulically controlled, powered by its own diesel engine.
The 806.2 STC enables cost-efficient production of high-quality fuel chips from forest residue with just one operator and one machine.
The 806.2 STC solution gives the contractor ”SIMPLY THE BEST” when it comes to productivity, chip quality, reliability, performance, maintenance, friendliness and overall chipping economy.
