Around 1972, the tree length logging system was introduced and was a major advancement over the chain saw logging system. It uses several major pieces of equipment, needing only one labourer for each machine. One machine is a feller-buncher, which cuts trees at ground level and places them in bunches.
Another machine is a Skidder which drags the bunches to the landing. In most cases, two Skidders were needed to keep up with the feller-buncher. Alternatively, a forwarder machine (photo) could be used. At the landing, a delimber machine removes limbs from the trees. A slasher machine cuts the trees to appropriate lengths and stacks the logs in piles for truck transport.
The tree length system can be very productive, but only if the labourers are there for each machine, each machine was working, and the weather was not severe. If a labourer was missing or a machine down, production was brought to a halt. If the weather was severe, the different machines would cause ruts in the ground making it hard for the machines to move around. This was particularly problematic since the tree length logging system requires a network of roads, skidding trails, and landings.

Today’s logger must consider many different criteria in a harvester. Harsh forestry conditions require equipment with various applications and with high productivity. The Caterpillar Harvester line includes models designed and built to be used in various applications from first thinning to final felling and that are able to handle trees of different diametres.
The Caterpillar Harvester line has been engineered specifically to address operator comfort. All cabs have a roomy interior, easy-to-reach controls and a suspension design that eliminates vibration.
Easy-to-reach controls give the operator full finger tip command. The harvesting head and boom and stick functions, plus the cab rotation are controlled from these levers.
Boom and stick consist of a two-section stick with a box construction design that extends 2,5 meters. Boom incorporates dual hoist cylinders, stick cylinder and extension cylinder. The boom and stick swings with the cab and is mounted along the side of the cab.

The operator may also adjust the pendulum arms to level the machine while harvesting. The pendulum arm suspension technology has revolutionized the industry. With this kind of versatility the operator can access trees in the tightest of thinning areas and toughest of sloping conditions.
Machine movement is controlled by floor peduls to free up the operator’s hands to maneuver the harvesting head with the boom and stick.
Excellent viewing area gives the operator a direct view of the harvesting head and the tree. The boom is mounted beside the cab, rather than directly in front. Windows are made of polycarbonate material to promote maximum protection for the operator.
Directional travelling is controlled by a floor pedul for easy changing of forward and reverse.
Operator ergonomics are improved through an eight-way adjustable seat, with seven-way adjustable armrests.
The computer aided bucking and measuring system is located in direct line-of-sight for easy viewing. A digital monitoring system displays all vital machine information and alerts the operator of potential hazards that could damage the harvester.

The SMV Rapid EGS is a harvester for exacting jobs, with all the attributes characteristic of a powerful single-grip harvester. The machine is equipped with a strong loader and stable chassis, which makes it excellent for handling trees in large-scale final felling. The basic model has 6 wheels, but will naturally gain greater stability as an 8-wheel model. The short, compact wagon chassis with double articulated frame locks forms an ideal base for RK 200 harvester loader, which has a very high lifting capacity.
With a stand-operating harvester, thinning is evenly distributed over the entire thinning area, and the strip road distance can be increased to just over 30 meters without additional manual felling. The Rottne 2004, stand-operating harvester, is narrow, compact, light-footed and flexible and has a unique pendelum-arm system that provides first-class terrain capability. Thanks to the leveling feature it is always possible to retain the machine width even in stony and very hilly terrain.
There is a great need for brush cleaning in young forest stands and that is mostly done manually with a powered brush-saw. There are no machines special built to do the brush cleaning mechanically, but the stand operating harvester Rottne 2004 can easily be changed to a cleaning machine. A cleaning head, a mounting kit and 4 big wheels are what is needed to convert the machine to a very efficient brush cleaner.
The Rottne 5005 is a highly efficient machine for both thinning and final felling. This harvester is compact, flexible and easy to manoeuvre, and also has a strong loader with excellent reach. Rottne 5005 has unique pendulum-arm system, and its advanced leveling function enables the machine to cope with very difficult terrain. This machine is easy to operate.
Rottne H-20 is primarily designed for final felling and large sized trees, but as it is versatile and easy to operate it can very well be used as a strip road operating harvester in later thinning. The powerful loader RK 200 and the unique design of the head EGS 700 with five feed rollers keep the trunks in a firm grip which is a benefit for delimbing and the measurement accuracy.

CNSIME traditionally attends to creation and perfection of the feller-bunching machines. The machine, which is carrying out the most dangerous and labour-intensive operation on cutting area, is worthy of it. All process of timber cuttings depends on its efficiency and an opportunity to realize the technical parameters.
CNSIME has developed and produced the first pre-production model of this machine. The main parameters are following:
b Capacity, h.p. – 225
b Productivity, trees / hour – 170
b Maximal diameter of the tree cut, sm – 56
b Maximal manipulator’ reach, m – 8…9,4
b Ground clearance under the chassis, mm – 600
b Ground pressure, kg/sm2 – 0,39
Dynamical, manipulating machine with a low ground pressure is focused on the consumers working with the trees of not large diameter. An opportunity to collect in shear-and-grapple device up to five trees of 20 sm in diameter provides the machine’ productivity up to 170 trees/h.
Powerful diesel AMZ-238 with a good resource, blocked with pump group provides good dynamics and propulsion performance characteristics of the machine. The integration of the turntable allows carrying out rotation with the working equipment and cutting trees in a corridor “on clearance” 5 m. The machine is equipped with one of the best in the world proportional electrohydraulic control system produced by “Danfoss”. Softness and accuracy of the positioning do not demand significant efforts of the operator.
The comfortable, well-protected cabin with the increased visibility and without “traditional” lattices reduces fatigue of the operator. The modern supervising and diagnostic equipment blocked in a monoblock with display of the current data to the liquid – crystalline display provides the operator with the necessary information.
The hydrosystem of the machine is produced with application of conduits for ultrahigh pressure.
The modern technologies of mechanical engineering provide good quality of the machine.

Caterpillar machines help maintain and preserve the fragile environment.
The IT28G is designed to provide more performance than ever before in a machine of this size. That means more work done in a day, less fuel consumed and minimal impact on our environment.
The IT28G uses the Cat 3116T low emission engine. This engine is designed to meet the world’s toughest emission regulations. Refinements to the turbocharger, cylinder head and pistons improve fuel combustion so there are less emissions. Plus there is a new system that closely controls fuel-to-air ration to help burn fuel efficiently and cleanly.
The IT28G’snew engine cooling system allows the engine to be fully enclosed so less engine noise escapes. Not only does the operator notice a significant drop in machine sound levels inside the cab, but spectators outside hear less noise too. The cooling fan traditionally a major contributor to noise, is now hydraulically driven. The result is cool, quiet operation with less disturbance to the environment. And IT28G is even quiter with the optional sound suppression package.
To help protect the earth’s ozone layer, the IT28G’s air conditioning unit uses only R-134 refrigerant which does not contain harmful chloro-fluorocarbons (CFC’s).
Engine oil, transmission and hydraulic filters are positioned vertically and are easy to reach so they can be removed without spilling. Lubricant filters and drains are also designed to minimize spills.
The IT28G offers excellent performance in a wide variety of applications such as bucket loading, material handling, utility work and industrial support.
Operator station is designed for total control in a comfortable, spacious environment. All control levers, switches and gauges are positioned to maximize comfort and productivity.

The wheel loader 966G Cat is designed to deliver excellent breakout force, fast load, precise maneuvering and comfort. Its durability is proven by field-testing. Its six-cylinder, direct injection, turbocharged and aftercooled DITA Engine is powerful, reliable, easily maintained and with low emissions. The engine delivers, at the rated speed of 2200 rpm, the flywheel power of 175 kw (235 hp). Four-stroke cycle design delivers long power strokes, efficient fuel combustion with low emissions, and excellent fuel economy. The direct injected fuel system provides a controlled fuel delivery increase as the engine lugs back from rated speed. This results in increased horsepower above rated power. Deep skirt engine block design ensures rigidity and reduces vibration. Cooling system features a hydraulically driven fan for less radiator plugging, lower noise levels and reduced fuel consumption (by 3% to 5% or more).
The 966G cab is a spacious and comfortable work environment that promotes productive operation. The cab includes outstanding viewing area, ease of service, ergonomic design and controls placement, improved ventilation and generous storage areas.
