HARVESTING & PROCESSING HEADS
In the short time Woodsman Pro series processing heads have been on the market, they have rapidly gained a reputation for productivity, reliability, low operating cost, and great backup service.
Felling and processing at the stump, on a landing, or under a yarder, the Woodsman Pro offers superior output and reduced reject rates associated with out of spec lengths, diameters, and fibre damage, as well as the obvious advantages of operator safety and comfort over traditional crosscutting and log making.
The five delimbing knife design ensures best-in-class felling, clean single pass delimbing, and precise log making (measuring and topping saw supplied as standard). All hydraulic and electric lines to the head are fed through a unique central rotating joint enabling the head to be rotated continuously in either direction. This simplifies operation of the head and eliminates expensive, vulnerable, failure-prone hosing common to other harvesting heads. www.acmecarriages.com
Caterpillar Forest Products
Caterpillar Forest Products is introducing a full line of processing heads designed and manufactured by SATCO, a New Zealand company. Caterpillar, the exclusive distributor in North America, offers the line and provides parts and support through select CatÒ dealers. The line includes seven processing heads that range from a weight of 2,618 lb. with a maximum cutting diameter of 25 in. to 8,500 lb. with a cutting diameter of 32 in. The heads are designed to be matched with Cat Forestry Machines (FMs), track feller bunchers, and the Cat 501HD harvester.
SATCO heads were built to handle the rugged logging conditions in New Zealand and have the durability needed by loggers in the Northwest. The beefy heads are constructed using high-grade materials. Hoses from the carrier to the head are routed through the linkage and are not exposed. This protects the hoses from damage and prevents them from over–bending causing premature failure. Main valves are rated at 6100 PSI (420 bar) and can easily handle carrier pressures.
The two-roller SAT223 and SAT325 and three-roller 3 Series head are especially well suited for processing big wood in the Northwest. They feature 3+ in. roller arm pins and heavy duty 3/4 in. main saw systems with 45 cc saw motors and large diameter bearings for smooth cross cutting and felling of large diameter trees. Stem capacity is 2.5-26 in. for the SAT223, 3-28 in. for the SAT325, and 3-22 in. for the SATCO 3 Series head. www.cat.com
Hahn Machinery Inc. continues to offer the HSG140 and HSG160 single-grip harvester heads. These simple and compact heads are intended to fell, delimb, and buck small timber and have been used extensively in thinning operations. Since 2006, Hahn has offered a high-performance version of its HSG series harvester heads. The successful “B” models feature digitally controlled, proportional, hydraulic valves with high pressure/high flow capability. The new hydraulic system enables the HSG “B” series to take full advantage of most modern excavator hydraulic systems and dramatically improves felling, delimbing, and bucking performance. www.hahnmachinery.com
Arbro harvesting heads are particularly designed for thinning and reforestation projects allowing the use of lighter and less expensive carriers such as small excavators. They are reasonably priced and provide a good return for a logger of small to medium size timber.
Arbro harvesting heads’ capability to fell, delimb, and cut-to-length makes them time and cost-effective tools for small timber operations. The Arbro 400 handles trees up to 14” and the Arbro 1000 up to 18”. The harvesters have an automatic stroke with a length of 29.5” instead of 26”. A tree can be delimbed by pressing a single button. Eight different preselected lengths may be programmed in. Any length can be chosen at any time. The delimbing and grip knives will open separately. A free DVD is available upon request. www.hakmetusa.com
Komatsu’s newest processing head, the 398, is designed to handle a wide range of applications with timber diameters in excess of 23”. Weighing in at 6,140 lbs., the 398 is a great match for track harvesters like the Komatsu XT machines and excavators in the 190-300 HP range.
The 398’s “carry style” feed system with 8,990 lbf rated feed force has three driven rollers and four motors. Two cylinders and an equalizer bar control the feed rollers. The main feed rollers cradle stems while pulling them into the head for a firm grip while the powered center roller reduces friction. The result is a secure grip with constant measuring wheel contact for accurate measuring. Four delimbing knives with an additional bottom mounted delimbing knife option assure high quality logs. Cutting is handled by a 31-inch capacity ¾ inch pitch bottom saw and an 18-inch integral topping saw.
Installations of the 398 on Komatsu PC290 and 300 excavators have been performing beyond expectation and have been well accepted in the inter mountain region.
Komatsu has also announced an update to the 25.6” cut, 2,646-pound 365 head with new cast measuring wheel arm and delimbing knives.
All Komatsu heads use the MaxiXplorer Head 3.0 platform, which combines the power of a PC, a 12-inch color monitor, Microsoft Windows®, and Komatsu’s MaxiXplorer for easy-to-use, intuitive control of all head functions. Komatsu’s unique EcoOiler provides programmable control of the amount of saw bar lubrication for the bottom and top saws. www.komatsuforest.us
