Valmet 911 Harvester Sisu Valmet has announced the new 911 harvester, built at its plant at Gladstone, Michigan. The machine is built for high-production felling, yet is nimble enough for thinning operations, says the company. The machine supersedes the Valmet 901.

The 911 is powered by a Cummins 6BTA turbo diesel rated at 169 hp at 2,100 rpm. A Valmet 960 Series II harvesting head has a 23.6''-diameter capacity. The head features cam-curve feed rollers; low-fric-tion feed, measuring and cutting functions are controlled by the Valmet VMM 100. Volumetric measurement is optional.

The 911 is equipped with the new Sisu Cranab 1400 telescoping boom that pro-vides a 30' reach.

New Blount Feller Bunchers Blount has upgraded its Hydro-Ax drive through rubber-tired feller bunchers to the Series EX 4. The four models are the 140-hp 411EX, the 185-hp 511EX, the 205-hp 611EX, and the 215-hp 711EX. Optional power plants range from 173 hp to 225 hp. Design changes in addition to added power include the use of a new triple-pump drive that provides live power for three separate hydraulic systems: attachment, lift and tilt, and steering. Pumps serving the lift and tilt and attachment functions are pressure-compensated.

These pumps use engine hp only when needed. Benefits include high-efficiency ratings through their operating life, lower operating costs through reduced fuel consumpti on, improved pump reliability and up to 50 per cent more tilt cylinder power, says the company. Overall length and wheelbase has been increased on all four models. The load cen-tre has been reduced for greater load-car-rying capacity and added stability; this change does not increase ground pressure. Other features include “Quick Steer” systems that provide a full turn left or right with just a quarter turn of the wheel. The standard inboard planetary axle (optional on the 411EX) has front and rear differential locks that can be engaged on the fly. Available attachments range from 16'' and 20'' shears and saws and a 22'' saw on the largest model, the 711EX.

Wood-Mizer's new LT40/30 Super portable sawmill can cut logs up to a rate of 54' per minute, depending on the species; this is up to 50 per cent faster than the LT40HD, says the company. Power options are 40-hp turbo diesel, 35-hp gas, or 20-hp electric. The machine handles logs up to 36'' in diameter and 21' long.

3-D Small Log Scanner Cutler-Hammer Opcon announces a new laser-based 3-D log scanner, the Model 450 Li ne Scanner. The scanner head wa s designed specifically for high-speed, small-log, 3-D scanning. Its scan rate of 100 scans per second nearly doubles that of other line scan scanners, says the company. A 500mm laser sees dark areas on the log sur-face and virtually eliminates sensitivity to ambient light.

The unit utilizes Cutler- Hammer / Opcon’s independent scan head feature, introduced on the Opcon 400. This gives the systems integrator the flexibility to cus-tomize scanner frame designs to individual installations. Complete 3-D profiles around the log are taken every 0.6'' along its length while trav-elling at 300' per minute.

Modular design permits one to eight heads to be configured together. The only interface needed to the scan heads is a high-speed fibre optic link back to a plug-in card in the host computer. A typical four-head scanning system will produce more than 1,000 data points from around the circ u m fe rence of the log on every scan. The 450 eliminates the necessity for field calibration; one-time factory calibration is all that is required. Startups are quick and easy, says the manufacturer.

Fabtek Feedback We were very pleased to read Tony Kryzanowski’s LSJ field report “A Bottom-Line Winner” highlighting Gary Raine and his Fabtek processor. [LSJ Feb/Mar, 1996] The article outlined our company’s marketing philosophy very well. The Fabtek processor operation was very well described with two exceptions. The wood processed was 10'' to 12'' jack -pine 70' tall. The bolts were being cut to 16'. Also, the average production rate was five cords per hour, not five cords per day. — Mike Berger Fabtek Incorporated
