Introduction.
In the forestry industry, various processes are carried out from felling to accumulation of timber. Of these, the process of clearing branches from felled trees and cutting them into specified lengths is particularly important. Processors are the machines that make this work more efficient. Processors not only improve the productivity of forestry operations, but also serve to reduce labor and improve operational safety. This article details the basic functions of processors, the benefits of their introduction, examples of their use, and their future prospects.
What is a processor?
Processors are heavy machinery used in the forestry industry for processing timber, and automatically perform tasks such as pruning and cutting down trees to a predetermined length. Also commonly referred to as “logging and lumbering machines” or “logging processors,” processors contribute greatly to improving work efficiency and safety.
Processors are used especially in areas where forestry is thriving and at large logging sites, where they can process large volumes of wood in a much shorter time than workers can do manually. By automating the entire process from felling to limbing and cutting, these processors reduce labor costs and time, and also improve the accuracy of the work.
- Delimbing: This is the process of brushing off the branches of the felled timber. This process, which is conventionally done manually, can be performed by a processor, dramatically increasing the speed of the operation. The processor is equipped with an arm that cuts branches while holding the wood, enabling efficient branch removal.
- Cross-cutting: Cutting lumber to specified lengths after pruning. The processor automatically measures the dimensions of the lumber and performs precise cross cutting. This function ensures that the quality of the wood as a product is consistent and prevents unnecessary losses.
Processor Structure and Function
The processor consists of three main parts. Each works in conjunction with the other to efficiently process wood.
1. Cutter Head
The cutter head is located at the end of the processor and functions to cut off branches from felled trees and cut the wood to the required length. This head is fitted with a chainsaw and sharp blades to clear away branches in a short time.
2. Grapple
The processor is equipped with a grapple to firmly grip the tree. This part of the machine stabilizes the wood while it is being processed, thus ensuring safe and efficient processing. The grapple is driven by a hydraulic system that provides a stable grip even on heavy timbers.
3. operation system
The processor is operated primarily hydraulically and can be operated remotely from the cabin of the vehicle. This allows the operator to manage the operation from a safe location while still on the heavy equipment. Some models are also equipped with digital display systems and cameras to further enhance work efficiency.
Processor Advantages
The benefits of implementing a processor are manifold. Below are some of the main benefits.
- Significantly improved efficiency: Processors significantly reduce work time compared to manual labor. This increases the amount of wood that can be processed in the same amount of time and improves overall forestry productivity.
- Reduced labor: Because the processor automatically performs both branch trimming and ball cutting, it does not require as many workers as in the past. As a result, labor costs are reduced and management becomes more efficient.
- Increased Safety: Forestry sites are not only hard work, but also a hazardous environment. The use of processors greatly improves safety by allowing workers to avoid working in hazardous areas.
- Improved quality: Processors cut lumber to exact dimensions, ensuring consistent quality of the lumber as a product. This will increase the reputation of the product in the marketplace and improve the selling price.
Processor Application Examples
Processors are being used around the world and have proven to be effective. Some specific examples are presented below.
- Finland’s Advanced Forestry: Finland is known for its efficient management of its forest resources, with processors playing a central role. Finnish forestry uses processors to process large volumes of wood quickly and accurately to ensure sustainable forest management.
- Large-scale logging in the United States: Processors are also widely used in the United States. In particular, processors are making a significant contribution to productivity in large-scale logging in large forested areas. This reduces labor and improves safety at the same time.
- Applications in Japan’s Mountainous Areas: Processors are also being introduced in Japan’s mountainous areas. Because much of the forestry work in Japan is done in mountainous areas, the mobility and efficiency of processors are of particular importance. This allows them to work efficiently even in harsh environments, thereby increasing forestry productivity.
Differences between processors and other forestry machinery
In addition to processors, a variety of other heavy equipment is utilized in the forestry industry. For example, there are heavy machines such as “feller-bunchers” and “forwarders,” each with a different role.
- Ferrabancha
Feller Bancha is a heavy equipment specialized for felling trees. It is responsible for felling and accumulating trees from their roots. Processors are often used in combination with feller bunchers to handle the post-felling process. - forwarder
Forwarders are heavy equipment used to haul away the timber that has been cut and processed. The forwarder is responsible for transporting the wood processed by the processor to the collection point or truck.
Differences between processors and other forestry machinery
A “harvester” is a forestry machine similar to a processor, but there are some differences between the two. Let’s take a closer look at the differences between the roles and functions of processors and harvesters and the situations in which they are used.
1.Differences in work processes
- Harvesters
Harvesters are heavy machinery that can perform a series of operations in a single machine: felling, branch clearing, and lumber preparation (cutting into specified lengths). Like a feller buncher, it has the ability to cut down a tree from the base, immediately remove branches, and cut the tree to the specified length for on-the-spot lumber preparation. The forestry work process can be completed in a single machine, allowing for more efficient operations. - Processors
Processors, on the other hand, do not perform the felling operation itself, but are machines that process trees that have already been felled. It receives the wood that has been cut by other heavy machinery, such as a feller buncher, and performs the limbing and cutting. For this reason, processors are often used in conjunction with other dedicated logging machines.
2. Differences in usage situations
- Harvesters
Harvesters are particularly suited for work in flat or large logging areas because they can handle the entire process from felling to lumbering. They are useful in a wide range of logging operations because they can move around a lot in the felling area and process trees quickly and one after another. - Processors
Processors are machines used to efficiently process timber that has been harvested, and are therefore suited for operations after the trees have already been cut and accumulated. They are especially used in situations where trees felled on steep slopes or in difficult-to-access areas are to be processed together, and are often installed in combination with other logging machinery for more efficient operations.
3. Differences in work efficiency and applications
- Harvester Efficiency
Harvesters can complete a series of tasks with a single unit, enabling efficient logging operations over a wide area. However, their use may be limited to certain terrain, as they may not perform adequately on steep slopes or in areas with severe terrain. - Processor Efficiency
Processors specialize in efficiently processing harvested timber and are flexible enough to adapt to terrain and ground conditions. They are especially highly productive in situations where accumulated timber needs to be processed efficiently.Click here for an article describing the Harvester.
