Marion 6360

Marion 6360 is a engineering topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Marion 6360 rather than just read about it. In short: Marion 6360, known as "the Captain", was a giant power shovel built by the Marion Power Shovel company. Completed and commissioned on October 15, 1965, it was one of the largest land vehicles ever built, exceeded only by some dragline and bucket-wheel excavators.

Key takeaways

Marion 6360 belongs to engineering; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Marion 6360 to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Marion 6360 from memory before moving on to harder problems.

Reference excerpt

Marion 6360, known as "the Captain", was a giant power shovel built by the Marion Power Shovel company. Completed and commissioned on October 15, 1965, it was one of the largest land vehicles ever built, exceeded only by some dragline and bucket-wheel excavators. The shovel originally started work with Southwestern Illinois Coal Corporation, but the owners were soon bought out by Arch Coal. Everything remained the same at the mine except for the colors which were changed to red, white, and blue. Like most mining vehicles of extreme size, the Marion 6360 required a surprisingly small crew to operate it (a total of four people) consisting of an operator, oiler, welder, and a ground man who looked after the trailing cable. The shovel worked well for Arch Coal until September 9, 1991, when a fire broke out in the lower works of the shovel, caused by a burst hydraulic line that sprayed the hot fluids on an electrical relay panel. This fire caused a great deal of damage to both the lower works and machine house. Afterwards, engineers from both Arch and Marion Power Shovel surveyed the damage and deemed it too great to repair, and the machine was scrapped one year later in the last pit it dug. The only Marion shovel that compared (in size and scope) to "The Captain" was the Marion 5960-M Power Shovel that worked at Peabody Coal Company's (Peabody Energy) River Queen Surface Mine in Central City, Kentucky. It was named the "Big Digger" and carried a 125-cubic-yard (96 m3) bucket on a 215-foot-long (66 m) boom. It was Marion Power Shovel's second largest machine ever built and the third largest shovel in the world. This "sister shovel" was scrapped in early 1990 in Muhlenberg County, Kentucky.

Worked examples

Example 1 — a first encounter with Marion 6360

Start with the simplest possible case. Write down what Marion 6360 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 Marion 6360 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 Marion 6360 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 Marion 6360

In research: Marion 6360 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 Marion 6360 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: Marion 6360 is common in secondary-school and first-year university syllabi. It links to neighbouring topics Engineering vehicles, Marion Power Shovel Company, Mining stubs, so understanding it makes those chapters shorter.
In everyday life: Look for Marion 6360 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.
