A log splitter is a piece of machinery or equipment used for splitting firewood from softwood or hardwood logs that have been pre-cut into sections (rounds), usually by chainsaw or on a saw bench. Many log splitters consist of a hydraulic pump or electric motor which then powers a hydraulic or electrical rod and piston assembly.
The output capacity of a firewood processor varies with the size and cost of the machine, from one cord per hour on a $22,000 entry-level machine (2020 prices)., [4] up to five or six cords per hour on a $60,000 industrial machine.
The vehicle may be articulated to provide tight turning capability around obstacles. A diesel engine provides power for both the vehicle and the harvesting mechanism through hydraulic drive. An extensible, articulated boom, similar to that on an excavator, reaches out from the vehicle to carry the harvester head. Some harvesters are adaptations ...
A feller buncher is a type of harvester used in logging.It is a motorized vehicle with an attachment that can rapidly gather and cut a tree before felling it. Feller is a traditional name for someone who cuts down trees, [1] and bunching is the skidding and assembly of two or more trees. [2]
A sawmill (saw mill, saw-mill) or lumber mill is a facility where logs are cut into lumber. Modern sawmills use a motorized saw to cut logs lengthwise to make long pieces, and crosswise to length depending on standard or custom sizes (dimensional lumber). The "portable" sawmill is simple to operate. The log lies flat on a steel bed, and the ...
They are usually driven by hydraulic power supplied from the surface and operated by commercial divers using surface-supplied diving equipment. Underwater chainsaw cutting may also be used by public safety divers. [30] Hydraulic chainsaws can be used to cut wood, concrete, brick and steel if the appropriate chain is used.
A hydraulic debarker is a machine removing bark from wooden logs by the use of water under a pressure of 700 kilopascals (100 pounds per square inch) or greater. [1] Hydraulic debarking can reduce soil and rock content of bark, but may increase the water content.
Some combination machines run all of their functions from a single motor; others may use more than one. Cutter heads are often shared: for example a jointer-thicknesser may use the same cutter head for both functions. The machines rely upon well thought-out designs which allow the user to switch from one function to another easily.
