What Are Forestry Equipment

Meta Description: Forestry equipment, including feller bunchers and log loaders, plays a crucial role in efficiently felling, processing, and transporting trees. Learn about the significance of this heavy machinery in forestry operations.

Forestry operations require specialized heavy machinery to harvest, transport, and process trees efficiently. This article overviews the various equipment used in the forestry and logging industries.

From feller bunchers and harvesters that fell and collected trees to forwarders and log loaders that transport logs to equipment that further processes wood – we will explore the different machinery and their key functions.

Key Takeaways:

• Forestry operations require specialized heavy machinery to harvest efficiently, transport, process, and split trees.
• Equipment like feller bunchers, harvesters, forwarders, and log loaders are used to fall, collect, transport, and load logs.
• Machines such as harvesters, Delimbers, and cut-to-length systems further process logs.
• Stump grinders and log splitters remove stumps and split logs as needed.
• Protective gear, including helmets, glasses, and boots, help ensure operator safety around this machinery.

Common Machinery Used in Forestry Operations

Feller bunchers, harvesters, forwarders, and skidders are some of the most common types of equipment used in forestry operations.

Feller Bunchers

Feller bunchers are highly productive machines that fill trees and bunch them for processing or transport. Fitted with a cutting head equipped with sharp blades or saws, feller bunchers can quickly fall trees via their rotating cutting disks.

Larger feller bunchers may be capable of cutting down trees measuring up to 60 cm in diameter. Many feller bunchers are also wheeled feller bunchers, featuring large wheels for improved mobility over rough terrain.

Harvesters

Harvesters are multi-functional machines that harvest, delimb, and cut trees to length in a single pass. Equipped with a harvesting head containing a saw and rotators, harvesters fell the tree. They processed it into logs of specified lengths.

Some harvesters are wheeled, while others are tracked for improved traction. Harvesters play a key role in modern logging operations by efficiently producing processed logs from the felling site.

Forwarders

Forwarders transport logs from the felling site to a landing area or roadside in forestry operations. Fitted with a cargo space and powered by wheels or tracks, forwarders “forward” logs and wood materials over ground.

Forwarders feature large wheels or tracks for mobility and can transport heavy loads of logs over rough terrain. Their cargo areas can hold 10 to 30 logs or smaller pieces of wood.

Skidders

Skidders are another machine used to transport logs from the felling site. Unlike forwarders carrying logs, skidders drag logs by lifting boom and cables. Powerful skidders are well-suited to dragging heavy logs or loads of logs through challenging conditions. They are commonly used in ground skidding applications.

Equipment for Transporting Logs

Transporting logs efficiently from the harvesting site to sawmills or construction sites requires specialized equipment.

Log Loaders

Log loaders play an essential role in loading logs onto transport trucks. Fitted with grapples or claws, log loaders can lift and load logs onto log trucks. Larger log loaders can lift and handle heavy logs with boom and arm attachments. Some log loaders feature large wheels or tracks for mobility over rough terrain during logging operations.

Log Trucks

Log trucks are heavily built vehicles designed to transport logs over public roads. Equipped with strong frames and suspension, log trucks can carry heavy loads of logs securely while operating on highways. Log trucks feature log bunks, stakes, and chains to secure harvested logs during transportation safely. Their bodies are designed to contain any loose bark or wood chips produced during transport.

Log trucks deliver wood materials from forests to industrial facilities such as sawmills and construction sites.

Transporting harvested logs efficiently requires machinery such as log loaders to place logs onto log trucks. These specialized vehicles then deliver the heavy logs and wood materials to their next destination, playing essential roles within the forestry industry.

Machines for Processing Trees

Once trees are felled, specialized machinery is used to process them further.

Felling Heads

Felling heads, or harvesting heads, are mounted on the front of feller bunchers and harvesters. Equipped with a rotating cutting disk containing sharp blades or saws, felling heads cut down trees with swinging hammers or blades. Felling heads may incorporate features like fixed tooth rotor systems to aid in cutting. They play an essential role in the initial felling and delimbing of trees during logging operations.

Cut-To-Length Systems

Cut-to-length systems allow harvesters and feller bunchers to process felled trees into logs of specified lengths at the stump. Equipped with a felling head to fall the tree and a delimbing knife to remove branches, cut-to-length machines then use their sawing mechanism to cut the trunk into logs of precise lengths.

This efficient system produces appropriately sized logs without further processing at a landing area.

Delimbers

Delimbers are machinery that removes the branches from felled tree trunks. Fitted with rotating knives or saws, Delimbers efficiently strip branches off logs to produce branch-free trunks.

Delimbers may be stand-alone machines or integrated into harvesters and cut-to-length systems. They help produce raw log materials for further processing down the supply chain of the forestry and lumber industries.

Various machines play essential roles in processing harvested trees into standardized log materials. Felling heads, cut-to-length systems, and delimbers help produce properly sized logs efficiently at the harvesting site.

Equipment for Removing Stumps

Once trees are felled, the remaining stumps must be removed to clear the area for new growth. Specialized machinery is used for this task.

Stump Grinders

Stump grinders are powerful machines designed to remove tree stumps to ground level. Equipped with a grinding wheel or cutting disk fitted with sharp teeth or carbide blades, stump grinders efficiently reduce stumps into woodchips.

The rotating cutting disk or grinding wheel is lowered onto the stump and spun at high speeds, shredding the stump material. Teeth on the cutting edge may be replaceable to maintain grinding performance.

Stump grinders play an important environmental role in clearing stump debris from harvested or developed sites. Their grinding function efficiently removes unwanted stumps left after tree felling operations.

Removing unsightly and potentially hazardous tree stumps requires heavy-duty equipment like stump grinders. With their rotating cutting disks and sharp blades, stump grinders efficiently reduce stumps to soil level, clearing the ground for future use. Their grinding capabilities help complete forestry and land development projects.

Machinery for Splitting Wood

Once logs are harvested and processed, some require further splitting into firewood or smaller pieces. Specialized equipment is used for this task.

Log Splitters

Log splitters are powered machinery designed to split felled logs into firewood. Equipped with a splitting wedge or blade, log splitters leverage significant force to break logs down along the grain into pieces suitable for burning in stoves or fireplaces.

Both electric-powered and gas-powered log splitters are commonly used, with gas models offering more power for splitting larger logs. Log splitters safely and efficiently break logs into manageable pieces for firewood.

Protective Gear for Operators

Working with heavy forestry machinery poses risks that require appropriate protective equipment.

Helmets

Sturdy helmets made of strong materials help protect the operator’s head from falling branches, flying debris, or other common overhead hazards in logging environments. Many feature face shields for added face protection.

Safety Glasses

Protective eyewear with reinforced lenses and frames, such as safety glasses, helps safeguard operators’ eyes from flying wood chips or other potentially damaging particles generated during forestry work.

Work Boots

Rugged, steel-toed work boots provide foot protection for forestry workers and operators. Their reinforced toes help protect from falling logs or equipment while working in rough terrain.
