It has been believed that the predecessor of contemporary man, homo erectus, initially used wood for fire. It was around 750,000 years ago and approximately 700,000 years later, he began to use wood for constructing simple dwellings. Presently, almost three quarters of a million years later, man has been using wood for similar purposes. However, in most cases, the manner in which timber has been harvested now is entirely different to the methods used in the long distant past.
A lesson in history
It would not be wrong to state that chopping of wood gradually evolved from moderately crude stone implements. However, more specific tools were casted from metals, such as bronze and iron, before rushing to the apex of mechanical creativity that has been born from the fires of industrial revolution. It has been carried out right through to the current era.
For a considerable time, the only mode to cut wood in small quantities was with a hand axe. Foremost, it was with blades made from shaped stone and consequently, from different metals. Anyone who has ever had the experience of cutting wood with a modern axe would be able to tell you that this form of wood cutting is a laborious task. Not to forget, anyone trying it with one fashioned from stone. The task would take ages.
The inception of modern tools
Both the Egyptian and the Roman civilisations have recorded the introduction along with the usage of first cross-cut saws that when used along with the traditional hand axe would greatly reduce the time taken to cut wood. Simultaneously, it would increase the output largely. However, it was not until recently that cross-cut saws were used in the actual felling of trees. Until then, they were primarily used to cut up already felled timber.
Fascinatingly, saws were used by the ancient Egyptians. They were designed to cut only on the pull stroke. On the other hand, Western saws have been designed to cut on the push stroke. Once the wood was cut or the trees fell, the lying timber was required to be moved. The easiest method to move large wooden logs was on water. The logs would simply float downstream or on a boat. Where this was not made possible, large animals were being used to haul the heavy loads through road.
However, modern times led to modern techniques. As a result, the introduction of chainsaw sped things up considerably, while taking more of backbreaking labour out of the task. The invention of, initially steam and then the combustion engine meant that moving of heavy goods in every industry was made simple and highly cost effective.
Presently, there have been a number of machines suitable to every industry. It would range from machines that could gather and cut several trees simultaneously before felling them, to the ones which fell, cut and de-limb trees to length.
Once they reach the road, waterway or rail through forwarders and skidders, which are machines that carry and drag logs respectively, timber, would be loaded onto the long distance transport. Amongst the different types of loaders used for this purpose, one versatile and safe medium has been the side loader. For comprehensive knowledge on loaders, you could log on to payeur.com.
