Mobile Chipper 806.3 ST

Mobile Chipper 806.3 ST

The 806.3 ST mobile chipper model is equally adapted to working off-road and at the roadside, producing fuel wood chips from forest residues. It has the capacity to process full-length trees and logs up to a diameter of 50cm for softwood and up to a maximum diameter of 40cm for hardwood, as well as brushwood.

The 806.3 ST consists of a highly efficient chipper, equipped with its own engine, delivering a compact powerhouse. The chipping unit’s low weight and small footprint makes this design suitable for installation on a variety of carriers such as trucks, trailers or hook-lift frames.

To ensure the most efficient chipping operation, the chipping unit is electronically controlled by our latest intelligent mobile chipping (IMC) control system.

The 806.3 ST is a very flexible machine and can be equipped with a number of accessories to suit different installations. For example, hydraulic pumps can be specified to operate the crane.

It simple, robust design, combined with our customized configurations, provides users with a flexible chipper that can meet a variety of demands, delivering smooth operations at minimal costs.

Drum chipper

The 806.3 ST chipper uses a robust drum chipper with a powerful infeed and closed drum for best chip quality; chip output is via a chip accelerator and chip tube. This combination provides the most energy-efficient chipping process and a consistently high chip quality.

Mounting frame

The chipper unit stands on a mounting frame with integrated brackets for the chipper and engine installation. Spring-loaded brackets for the carrier vehicle chassis allow for a degree of independent movement by the chipping unit and carrier frame. A fold-down service platform is available for knife exchange and maintenance, and a roofed cage with hatches protects the diesel engine.

Diesel-engine

The 806.3 ST mobile chipper features a powerful Scania DC13 313A European Union (EU) Stage V certified engine. Its brake-specific fuel consumption of 189g/KWh puts the unit among the highest-efficiency engines of its type in the world. It has a power output of 368 kW (500hp) and a torque of 2,500Nm. The complete installation includes a side-mounted radiator, transmission, starter batteries, a 350-liter fuel tank, AdBlue tank and exhaust system. Bruks Siwertell has updated the chipper installation to support the maintenance and service of this engine.

Hydraulic system

This chipper has a load-sensing-type hydraulic system and is powered by a variable displacement pump. The chip accelerator is powered by a hydrostatic pump, which enables the accelerator to run at a constant speed regardless of the engine’s revolutions. The cooler fans are hydraulically powered and can be reversed for cleaning the cooler. A standby electrical pump can be used when operating the hydraulic functions when the engine is switched off, for example, when changing the knives during maintenance.

Electrical and control system (IMC)

Our advanced control system is built on a well-proven platform of hardware and our own in-house software, intelligent mobile chipping (IMC). Together, these provide a complete electrical control and monitoring system for the chipper unit. The chipper and engine functions are operated from the cabin where the operator can monitor all the engine’s parameters as well as the hydraulic system.

There is also monitoring equipment and automatic controls for chipper safety functions, such as the anvil holder’s position and electronic infeed load control.

Chipper controls are mounted beside the crane levers and the large touchscreen is positioned at an ideal viewing angle for the operator. The color screen can also be connected to external cameras. It is designed to be an intuitive communication link between the operator and monitoring and setting the chipper functions.

The chipper also features a remote connection via a GSM mobile phone to deliver easy online troubleshooting from Bruks Siwertell’s support centre.
