Truck Fest 2013: Smokey Big Rigs Burnouts & Drag Racing Revealed
( http://www.TFLtruck.com ) When you think of a Big Rig Semi...you probably
don't immediately think of drag racing...or do you? This weekend at
Bandimere Speedway just outside of Denver, Colorado hundreds of Big Rig
Semi trucks lined up on the drag strip to see which one is the kind of the
mile high drag strip and which one is the fastest mile high pickup
dragster. Can a big rig run a sub 20 second quarter mile? You bet. Can a
big rig run a sub 15 mile....no problem. Can a Big Rig run a sub 10 second
time? You'll have to watch the video to find out. In another fun and
informative TFLtruck video we see what happens when the Big Rig Semi Trucks
line up behind the Christmas Tree.

Auto Assembly Line: American Harvest (Revised) 1955 Chevrolet Division GM; Narrator: John Forsythe

Survey of raw materials going into cars leads to fine color assembly line
footage. "This institutional film was designed to promote Chevrolet's
corporate citizenship rather than any specific model of automobile. While
it forcefully demonstrates how central automobile manufacturing is to the
American economy, it even more strikingly shows the effects of the
automobile upon our landscape. Bombastic narration is accompanied by
excellent images of automobile manufacturing, the extraction and processing
of raw materials from the earth, and mid-1950s consumerism... Narrator:
John Forsythe. Revised from the original 1951 version."
Public domain film from the Prelinger Archives, slightly cropped to remove
uneven edges, with the aspect ratio corrected, and mild video noise
The soundtrack was also processed with volume normalization, noise
reduction, clipping reduction, and/or equalization (the resulting sound,
though not perfect, is far less noisy than the original).
An assembly line is a manufacturing process (most of the time called a
progressive assembly) in which parts (usually interchangeable parts) are
added as the semi-finished assembly moves from work station to work station
where the parts are added in sequence until the final assembly is produced.
By mechanically moving the parts to the assembly work and moving the
semi-finished assembly from work station to work station, a finished
product can be assembled faster
and with less labor than by having workers carry parts to a stationary
piece for assembly.
Assembly lines are the common method of assembling complex items such as
automobiles and other transportation equipment, household appliances and
Assembly lines are designed for the sequential organization of workers,
tools or machines, and parts. The motion of workers is minimized to the
extent possible. All parts or assemblies are handled either by conveyors or
motorized vehicles such as fork lifts, or gravity, with no manual trucking.
Heavy lifting is done by machines such as overhead cranes or fork lifts.
Each worker typically performs one simple operation...
Consider the assembly of a car: assume that certain steps in the assembly
line are to install the engine, install the hood, and install the wheels
(in that order, with arbitrary interstitial steps); only one of these steps
can be done at a time. In traditional production, only one car would be
assembled at a time. If engine installation takes 20 minutes, hood
installation takes five minutes, and wheels installation takes 10 minutes,
then a car can be produced every 35 minutes.
In an assembly line, car assembly is split between several stations, all
working simultaneously. When one station is finished with a car, it passes
it on to the next. By having three stations, a total of three different
cars can be operated on at the same time, each one at a different stage of
After finishing its work on the first car, the engine installation crew can
begin working on the second car. While the engine installation crew works
on the second car, the first car can be moved to the hood station and
fitted with a hood, then to the wheels station and be fitted with wheels.
After the engine has been installed on the second car, the second car moves
to the hood assembly. At the same time, the third car moves to the engine
assembly. When the third car’s engine has been mounted, it then can be
moved to the hood station; meanwhile, subsequent cars (if any) can be moved
to the engine installation station.
Assuming no loss of time when moving a car from one station to another, the
longest stage on the assembly line determines the throughput (20 minutes
for the engine installation) so a car can be produced every 20 minutes,
once the first car taking 35 minutes has been produced...
The assembly line developed for the Ford Model T began operation on
December 1, 1913. It had immense influence on the world. Despite
oversimplistic attempts to attribute it to one man or another, it was in
fact a composite development based on logic that took 7 years and plenty of
intelligent men. The principal leaders are discussed below.
The basic kernel of an assembly line concept was introduced to Ford Motor
Company by William "Pa" Klann upon his return from visiting Swift &
Company's slaughterhouse in Chicago and viewing what was referred to as the
"disassembly line", where carcasses were butchered as they moved along a
conveyor... The process was an evolution by trial and error of a team
consisting primarily of Peter E. Martin, the factory superintendent;
Charles E. Sorensen, Martin's assistant; C. Harold Wills, draftsman and
toolmaker; Clarence W. Avery; Charles Ebender; and József Galamb...
