It is the constant challenge of using unpaved roads, dangerous trek through the wild countryside, and of course the ever present danger of working with large trees. But despite the risks in line with the job name, the forest still managed to feel confident and secure with the help of all the logging trucks.
Brute force
Before the advent of logging trucks, logging rely primarily on brute force. The trees were cut manually with cross. The newspapers were then attached to a yoke of oxen, horses or mules pulled up in a mill nearby. Other means of transport of logs was shot down by the rivers downstream plants will drift.
Skidder and railway carriages
The brutal methods of capture and transport of logs and finally, after the introduction of mechanical devices to record changes in the form of steam winches and railroad cars. Both sets the trend for timber transport from late 1800 to early 1900. Although traditional air and the cars seemed the ideal equipment for the transport of logs at the time, set up transmission lines for skidders or on miles of track was too expensive to use for small operations forest.
Internal combustion engine
The introduction of cars, powered by an internal combustion engine, the alternative of kindling for log transport. Although trucks are not the same capacity as the cars or the wind, they were better in terms of operating costs because they operate on a road, eliminating the need systems of pulleys costly or complex to detect.
Unlike current standards, were the first vehicles used for flat simple application are not specifically related to the position. They were too weak and lack the security features essential for this unique opportunity. Because of this shortage has been the modification of the truck for the timber industry slowly and that small businesses use for their operation.
After World War I and World War II
The wide use of trucks to connect only started just after the First World War and the Second World War. After the war there were many military surplus vehicles. Military vehicles offer more power and reliability than previous models. Added to low operating costs, was the most appropriate equipment for logging truck.
