Reference excerpt

Sakari Pinomäki (1933–2011) was a Finnish systems engineer and an inventor, who pioneered the mechanized forestry industry. He was the founder of PIKA Forest Machines which produced the first purpose-built forest machine in 1964 in Ylöjärvi , Finland. His inventions had over 50 patents.

History Sakari Pinomäki's first company, PIKA Forest Machines, is credited with designing the first self-propelled tree length timber processor, the PIKA Model 60, in 1968, and the first fully mobile timber "harvester", the PIKA Model 75, in 1974. These machines differed significantly from other "retro-fitted" forestry machines in that they were designed from inception to be timber harvesting and processing equipment, and were not conventional farming or earth moving equipment with additional apparatus welded onto them to allow timber processing work to be possible. Pinomäki coined the term "harvester" to describe his Model 75 machine, which differs from a tree length processor in that a harvester grips, fells, de-limbs and sections the tree on site, while a processor simply de-limbs a tree that has been felled by chain saws and dragged to the delimbing equipment. His designs and innovations have been subsequently copied by at least five other major manufacturers of heavy timber equipment, including Timberjack, Valmet and Ponsse, and were instrumental in developing the "Scandinavian" system of timber harvesting, which is far more sustainable and nature conserving than the methods employed up till the mid-20th century. The two machine harvester-forwarder system consequently became the worldwide standard for sustainable forestry. One of the most significant of PIKA's inventions has been the Paralcon Hydraulic valve system that can be used on any twin boom extending-retracting crane. This valve uses return oil flow pressure to power the extension piston, and flow oil pressure to power the retraction movement of the crane, as opposed to standard configurations that use additional pumps to power these crane movements. The result is that far less motor torque is necessary to operate the crane, which consumes far less fuel; this in turn saves operators money and reduces CO2 emissions for the machinery in use. Additionally, S. Pinomäki Ky PIKA was first to market in the early 21st century with the world's first production "Combination" machine, a single machine that can function in both harvester and forwarder roles. This 50 percent reduction in machinery to perform the same harvesting work means far less environmental pollution from CO2 emissions and terrain damage from machinery operation, and has again be co-opted by every major manufacturer of heavy timber processing equipment. Sakari died on July 29, 2011, after a battle with pancreatic cancer. He is survived by his two daughters and three grandchildren.

Worked examples

Example 1 — a first encounter with Sakari Pinomäki

Start with the simplest possible case. Write down what Sakari Pinomäki claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In engineering, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Sakari Pinomäki before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Sakari Pinomäki ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Sakari Pinomäki

In research: Sakari Pinomäki appears in engineering research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Sakari Pinomäki in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Sakari Pinomäki is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1933 births, 2011 deaths, 20th-century Finnish engineers, so understanding it makes those chapters shorter.
In everyday life: Look for Sakari Pinomäki outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
