SAMPO ROSENLEW HR46x

 

SAMPO ROSENLEW HARVESTER HR46x


The HR46x is the number one choice for first thinning. Even more powerful than its predecessor HR46, the harvester has a larger, 140cc pump and an Agco Power 49 AWF engine. These changes improve performance and reduce fuel consumption, which translates to increased profitability of thinning operations for the owner.


Power transmission is now fully hydrostatic to allow for rapid movement from tree to tree without increased engine speed. Gear changes in multi-speed motors are done electronically or even automatically. An operating mode can also be selected from the operation automation menu, which increases the diesel engine RPM to maximum and automatically enables maximum transmission speed.
The cabs of Sampo-Rosenlew harvesters have always been placed on a separate frame from the engine, so users of Sampo-Rosenlew harvesters are accustomed to a comfortable and quiet work environment. Add to this the changes described above, reduced engine speed, the removal of the gearstick from the cab, as well as a number of other modifications in this model - the cab of the HR46x is incredibly quiet.


Chassis
A thinning harvester operates in young sections of forest. They are kept relatively dense in order to maximize the growth rate. High-quality thinning requires that the harvester is rather small and can be manoeuvred in small space. Furthermore, the machine weight must be relatively low. The HR46x meets these requirements. Further modifications have been made resulting in a light but strong chassis. The narrow harvester has a middle joint with a 50-degree turning angle resulting in unique manoeuvrability. The outer turning radius is 402 cm. Tyre width can be chosen between 500 and 650 mm.

Drive transmission
The HR46x harvester is equipped with full hydrostatic drive transmission. In this system there are no vulnerable axles and there is no train of gears. Changing from one gear to the next in the multi-speed radial piston motors is done electrically. The torque in the Sampo Hydraulics drive motors is high as soon as the machine starts to move. Since the wheels are constantly rolling without scratching, no marks are left on the terrain in the forest to be thinned. The turning of the harvester is also harmless to the ground because there is no bogie axle.

Cab
The Sampo Rosenlew factory also manufactures the spacious, silent cab which helps the operator to work efficiently. From the HR46x cab it is easy to see the tree tops, which is a requirement for the correct choosing of trees to be harvested. The cab meets the official safety standards and is specially designed to be used in a dense thinning forest when the remaining trees must be left unharmed. The cab features many details that make it easier for the operator to work and feel more comfortable.

Crane
The HR46x harvester has a 7.1 meter parallel crane with sufficient 55 kNm lifting capacity to ensure swift working. The crane is also very flexible to use even in a dense forest. The side tilt, which can also be switched on to work automatically, helps to pick the very trees that the operator wants to remove. Furthermore, it helps when operating on a slope or on rough terrain. The low construction of the crane improves the sideways stability and visibility towards the trees to be felled. The vertical fastening plate serves the same purpose, bringing the crane foot as close to the operator as possible.

Harvesting head
We only use harvesting heads from well-known manufacturers. The brands are Kesla and Keto. For thinning, the head must be small and designed so that it can be easily moved to the stem to be felled without harming the remaining trees even in a dense forest. The type of head and accessories are selected on the basis of intended use. For example, there are specific applications or equipment for the standard harvesting head designed for producing energy wood.

Engine
Sampo Rosenlew uses engines manufactured by Agco Power with several decades of experience in Linnavuori, Nokia. The power plant of the HR46x is the TIER 4 final phase common rail and SCR technology-equipped Power 49 AWF diesel engine. The low fuel consumption of the low-emission engine, coupled with extended service intervals guarantee minimum operating costs. It has 124 kW of power and the torque is the highest exactly in the RPM range that is used the most in operation. The engines are silent and have been made to last.

Measuring computer
Measuring of the wood volume as well as controlling of the harvesting head is done by the measuring computer. Since there is a variety of customer needs, the Motomit computer that we use can be equipped with software of different levels. If there is need for functions requiring PC level power, the personal computer is coupled side by side with the measuring computer. This way a possible malfunction in the PC does not prevent the use of the harvester. With a Motomit computer the customer has access to all the necessary functions such as:
• Optimizing of crosscutting
• Harvester head steering, control and trouble shooting
• Working hour follow-up
• Wireless transmission of production information.
