Albach Diamant

With travel speeds of 45 mph, the Albach Diamant 2000 can be driven on local and state highways from job to job, even hundreds of miles apart. At the tree stand, its full-time, four-wheel drive allows it to navigate even rough terrain. Upon arrival, the operator pushes one button and the Diamant 2000 converts from transportation mode to chipping mode automatically in 20 seconds and with its aggressive infeed can immediately be put to work handling and processing timber. The Diamant 2000 allows a tight control on the chip sizing, from microchips all the way to 2.5”. This way, the chips can be used for multiple applications.

Customizable overall to meet an arborist’s particular geographical or application needs, the crane-equipped Albach Diamant 2000 can churn out up to 500 cu. yds. of chips per hour.

Once the Albach chipper is driven to the job site, its computerized cabin is transformed from a highway-mode transport pod into an elevated work station providing the operator with an eye-level view of timber handling, chip production and delivery. The spacious, high-tech, air-conditioned cab is comparable to that of the world’s most modern agricultural and construction equipment.

For the accurate placement of chips, the unit’s extended-angle chute can be swiveled up to 270 degrees and adjusted up and down by up to 10 ft. This allows chips to be loaded directly into trucks parked in nearly any position nearby. www.sennebogen-na.com


albachBandit Industries

Model 2460XP effectively grinds chunk wood, brush and whole trees. It is equipped with a 60” wide by 30” diameter cuttermill, a 60” wide by 24” mill opening. This machine uses a 30-tooth cuttermill running Bandit’s patented saw-tooth style cutterbodies that regulate the size of the tooth’s bite. Most of the material is sized in the initial cut, so material exits the large screening area quicker. This leads to a more uniform end product, and less wear and tear on the grinding mill. The track-type infeed conveyor efficiently feeds material to the 60” wide by 30” diameter feed wheel yoke, the same size as the 3680XP.

The mill turns down against a fixed anvil. The infeed conveyor butts closely to the anvil to limit wedging of material between the conveyor and anvil. The down-turning mill and feed system ensure a smooth, controlled flow of material to the mill, maximizing production while adding to the uniformity of the finished product.

Like the larger 3680XP, the 2460XP has a unique waste gate that makes it easy to remove any contaminants from the mill and screening area, limiting damage to the mill and wear parts.

The Model 2460XP is maintenance-friendly with easy access to wear items, and simple hydraulic and electrical systems. Screens are simple to change using the standard screen changing arm, and ladders, steps and handrails help operators feel secure while climbing and working on the machine. There is easy access to the mill for changing teeth and cutterbodies. www.banditchippers.com


barkoBarko

Driven by a 520 hp engine, Barko’s CH6025 whole tree chipper is ruggedly built with an 8-inch reinforced tube frame to handle trees up to 22 inches in diameter. The machine offers enhanced hydraulic control features and patented ConeHead.

The unique ConeHead drum offers a 35-inch throat opening that makes fast work of big jobs. The drum’s knife design includes 8 steel in-pocket knives with two usable edges per knife. Instead of chopping, the ConeHead drum utilizes a more efficient slicing motion that delivers more chip loads per gallon of fuel. The slicing action also produces higher quality and impeccably consistent wood chips for biomass fuel systems.

The CH6025 features an infeed table with replaceable floor. One horizontal and two vertical hydraulic feed rollers consume mounds of limbs and tops quickly, and large carbon steel fan blades on the drum ends throw chips forcefully into collection trucks to pack in more material. Electrohydraulic system comes with wireless remote for safe, effective operation.

Dual air-brake axles are each rated to 22,500 pounds. www.barko.com


BruksBruks Rockwood

The Bruks Mobile Chipper has been a leader in biomass processing for over 60 years in Scandinavia, which means it was born in an environment where hard and softwood biomass has less than a 30 percent moisture content.

The Bruks Drum Chipper has either 2 or 3 full length knives, depending on the application, (i.e. for the production of energy or microchips). There is no introduction of dirt, which is inherent in other chipping systems utilizing skidders.

This one machine system has a low operation cost per hour and provides more flexibility since only one machine has to be moved from site-to-site versus 3 to 4 machines.

The Bruks Mobile Chipper is available for forwarder and truck configurations. www.bruks.com

diamond z manufacturingDiamond Z Manufacturing

The Diamond Z grinder is one of the premier grinders in the heavy industrial waste reduction equipment industry. These grinders have the ability to process large stumps and logs, while still producing a fine consistent finished product at fast production rates. Diamond Z horizontals are designed for processing brush, yard waste, clearing debris, storm debris, C&D waste, other mixed woody feedstocks, and asphalt shingles into salable products.

The grinders allow operators to more efficiently achieve small particle sizes required for boiler fuel, landscape mulch, animal bedding, and other finished products. As a rule, horizontal grinders better process longer, pre-organized material typically found in land-clearing operations. This is because of the long infeed opening which reduces the need to shorten material significantly before grinding. Machines range from 30,000 to over 160,000 pounds, with horse powers ranging to well beyond 2,000.  Diamond Z grinders are transportable and move conveniently and are cost effective even for the smaller jobs. 

All Diamond Z grinders are offered with Tier 4 Final emission rated engines as well as track, wheel and stationary mounted either diesel or electric powered. www.diamondz.com
