Bruks-Siwertell
Decades of experience, combined with customer-driven technological developments, mean that Bruks Siwertell offers the most comprehensive portfolio of market-leading mobile chippers. These powerful, high-capacity machines can be used off road, at the roadside or in terminals for the production of quality biofuel wood chips from forestry residues.
Bruks mobile chippers have been developed and optimized for the cost-effective production of biofuel chips, and have revolutionized the energy harvest. They offer very high capacities and reliability, and ensure consistent chip quality and the efficient production of renewable energy.
Bruks mobile chippers and chipping systems produce biofuel chips with consistent qualities, densities and high energy and low moisture contents. Our mobile chippers offer the ability to turn full-length trees, logs, existing slash piles, tops, branches, and forest residuals into biofuel chips, or micro-chips for wood pellet production, generating renewable energy from forest materials that would typically have been left to decompose.
Our mobile chippers are a time-tested concept combined with the continuous development of new innovative solutions. All Bruks mobile chipper models are tailormade and designed to offer flexible operations. They can be specified with their own engines, or are truck or tractor-driven units. Bruks chippers deliver impressive wood-processing capabilities in the field, with the largest of our units processing timber up to a diameter of 60cm.
Bruks mobile drum chippers are well known for their robust design, reliability and long service lives. They can be maintained and serviced easily and safely. Innovative technology means the chips flow smoothly through the chipper, minimizing dust, wear and energy consumption, while maintaining extremely high chip quality.
Effective mobile chipping requires power sources to be compact, robust, and capable of providing the high-torque properties that chipping requires. We are specialists at delivering this. Self-powered Bruks chippers benefit from low weights and compact designs. These chippers are particularly suitable for installation on a variety of carriers such as trucks, trailers or hook-lift frames, and can be equipped with a number of accessories to fit different installations.
All Bruks mobile chippers have hydraulically driven feed units with high retraction forces and closed drums. Along with the latest Bruks chip accelerator technology, our machines deliver impressive chipping drum efficiency, chip quality and chip discharge rates.
Bruks on-truck chippers can easily relocate to different chipping sites, delivering high levels of operational flexibility and efficiency. They are also well-known for their reliability and long service lives. Our on-truck systems have been combined with state-of-the-art truck technology and all electrical and hydraulic systems are interconnected. On the truck, there is a mounting frame and foundations for the chipper, chip bin and crane.
Bruks drum chippers feature cutting-edge innovations. They are designed to have a powerful, high-capacity infeed and a closed drum for best chip quality. Chip output is maximized by a chip accelerator. Different chippers can be specified for various applications and a number of accessories can be supplied to ensure our market-leading mobile chippers perfectly suit your needs.
Mobile chippers can be trailer-mounted. For these units, trailers are equipped with a transmission system for the chipper, a common control system for the crane and chipper, and hydraulics with a distribution gearbox powered from the tractor’s power take-off shaft (PTO). This system allows the hydraulics to be used without the chipper rotating.
Our control systems ensure complete electrical control and effective monitoring for our chipper units. Different chippers have various control arrangements, with the latest units employing our innovative intelligent mobile chipping (IMC) control system. If fitted with an engine, control systems monitor engine oil and water temperatures and levels, and oil pressure. Indicators are installed to identify filter clogging in the hydraulic oil system. Monitoring systems are also included for chipper safety functions such as the position of the anvil holder and electronic infeed load control.
Intelligent mobile chipping (IMC) is an advanced control system for optimizing power management, fuel efficiency and the throughput of wood chips for customers using our latest on-road, off-road and terminal Bruks mobile chippers.
Drawing on decades of experience, IMC takes advantage of major digital advances. It integrates all sensor inputs: in addition to controlling the chipper itself, IMC controls the power source, regardless of whether it is an industrial diesel engine or a truck engine; lighting; heating; reversing cameras; and most importantly, fuel economy. As a ‘plug and play’ system, it is straightforward to add and integrate additional components, including crane control, when required.
Through a CAN bus control system, IMC gives users the ability to optimize its operating profile for individual chipping tasks. A RiFuce circuit breaker unit replaces traditional fuses and relays, and a built-in logic function controls electric motors, such as fans, in a more intelligent way. Cable harnesses are designed in accordance with the most stringent industry standards, and the entire system meets with current requirements for fire and machine protection.
Inside the operator cabin there is a 10-inch color touchscreen, with easy access to settings and diagnostics. Controls are located next to the crane joysticks. Alternatively, with integrated crane control, all controls are included with a specially designed lever box. Outside, in the chipper unit, is the robust Parker IQAN, offering toughness and reliability.
IQANrun or IQANgo applications offer remote support and troubleshooting via GSM, enabling ever-greater redundancy.
