Derived from
the trade of carpentry, a millwright
originally was a specialized carpenter who
was trained as a carpenter and as well had
working knowledge of gear ratios, driveshaft
speeds, and other equations. The "mill" in
millwright refers to the genesis of the
trade in building flour mills and other
watermills and windmills.
A
millwright today is someone who
maintains or constructs industrial machinery
such as that which would be related to
assembly lines, also pumps, valves, printing
presses, etc. Their job requires a thorough
knowledge of the load bearing capabilities
of the equipment they use as well as an
understanding of blueprints and technical
instructions.

A pile
driver or piledriver is a
mechanical device used to drive piles into
soil to provide foundation support for
buildings or other structures. The term is
also used in reference to members of the
construction crew that work with
pile-driving rigs.
Piledriver operators
use large machines, mounted on skids,
barges, or cranes to hammer piles into the
ground. Piles are long heavy beams of wood
or steel driven into the ground to support
retaining walls, bulkheads, bridges, piers,
or building foundations. Some piledriver
operators work on offshore oil rigs.
Piledrivers work with a variety of hand and
portable power tools, and frequently cut,
join and fasten metal construction materials
using welding equipment and torches. |
