Forestry Machine

Here's a summary of forest equipment history

Forest machinery and tools have gone a long way since people used only axes and picks. In the late 19th century, mechanization was introduced. Dolbeer and Carson Lumber Company invented the steam donkey in 1881. The logging machine was developed by John Dolbeer. The steam donkey became obsolete when the internal combustion engine was introduced. The stage went much later with trucks and heavy cutting machinery. Damp donkeys were however very helpful in moving other machinery like crane, pile driver, slide jammer and cherry picker.

At the beginning, logging tools fell into manual gang saws and logs were transported downstream by sleighs or sea.

The Skids in the first measures have been invented to transfer logs. Basically they were poles on trails that were crossed. This method was simplified by the above-mentioned steam powered winch, the' donkey.' With less cable effort logs have been moved.

By the end of the 19th century, only rotary and gang saw trees were still cut and mills had band sawings. At the beginning of the 1900s, self-propelled vehicles and lorries were slowly being replaced by horse-drawn logging sleighs. Before being sent to the mill, the logs had to be transported to a river or a ship.

The first articulated lorry with a trailer was introduced in the 1920's, but another decade passed until a wooden lorry was planned. In 1939, T.A. established Peterbilt. He later bought Fageol and Waukesha for which he used to design logging trucks that set the industry standards of today. Peterman Peterman

The Forest Harvester

The Mammoth Tree Shears, a US-based company, had initially made a device with tracks capable of shaving trees with trunks up to 30 cm in diameter, but this wasn't very similar to a forest harvesting facility. In the early 1970s a self-propelling device made by Sakari Pinomaki under his company PIKA was launched in the first model which is more or less the same today. The first single grip harvester was demonstrated by SP Maskiner in Sweden in the early 80s. The best solution for forestry plantations were these devices.

Trees near rivers had for a long time been the first to be cut down, but transport needs quickly became a top priority. Domestic animal-drawn sleighs were the answer before the advent of internal combustion. It was time for the logging truck to continue after the steam donkey cycle had passed.

The United States has been one of the first countries to use trucks. After the end of the First World War a large number of military trucks were converted into logging trucks.

Lorries became less and less primitive and their motors improved substantially in the 1930s. The pneumatic tires were a major improvement. In the meantime, the logging industry had just as important trucks as the trains. While designing the truck model, the WWII played another key role.

The Evolution of the Skidder

At first, domestic farm animals also pulled skidders. It continued until the 1920s, when gasoline-fuelled machinery was gradually being implemented to replace animal energy. Such machines have winches that make the logs much easier to raise than before. Also used were small trailers known as' bummers.' The forwarder was later introduced, because it can be carried by a more practical machine

Clearly, there was a steam engine in the first prototype of the mechanical skidders. Some were more powerful than steam donkeys, but some had the same purpose in theory. Clyde Skidder, introduced in the early 1920s, was one of the first fully functional machines of this kind.

The use of these devices was still extremely dangerous given the advancement of forestry equipment. Some companies combined the role of the skidder with a loader and reached the loader cables in specific locations such as New Zealand for as far as five miles.

The Equipment Used Today

Marks such as John Deere, Komatsu, Ponsse and Caterpilar are decades old in forestry equipment manufacturing. Today's technology is far more sophisticated. This incorporates cutting-edge technology and is much safer than the devices used in the early decades of the 20th century. The machines today are also far more powerful.

For example, harvesters are installed on various platforms such as pumps, tracks or wheelbases fitted with modern diesel engines. Most modern machines have a safe and comfortable operator environment–a fully enclosed cabin. Feller bunchers–devices that are used to gather timbers and the above-mented skidders that pull cut logs out of the woods–are among the main forest equipment used today. Next is the loader-they pick up wood and load it onto wooden trucks. Among the other common machines are transmitters, borers, mulchers, and debarkers.
