A very pleasant visit has been shared with my SON RON, GRANDSON BRADEN, AND SHARON, MY # 2, ( MOM and GRANDMA) who treated us Boys to one of her delicious Sunday Dinners.
BRADEN is employed by WAL-MART, SHARON is a Nurse for the past 42 years (I treated her to LPN Nurse's Schooling ... seems like two lifetimes ago ..., and RON is battling back injuries and DIABETES the past many years; all in all, we are OK.
As the City of TACOMA is only 5 miles from RON's home in FEDERAL WAY, Washingto, I have used free hours to visit the Port of TACOMA. From 1964 'til 1970, I was employed as Contracts Manager at STAR IRON and STEEL in TACOMA, a major World Class CRANE Manufacturing Company, .
Major equipment SIS designed and manufactured were CRANES, especially CONTAINER CRANES serving various Sea Ports Loading and Unloading Container SHIPS in the early days of Containerization and the LAND BRIDGE across America.
The PORT of TACOMA has evolved into a SUPER CONTAINER PORT since my absence.
Following Blog update depicts TACOMA's PORT, at this moment, in the throes of modernization and expansion.
Among other achievements at the Port of TACOMA is development of technology of design and manufacture of massive CONCRETE Structural Beams, Girders and Vessels ... also introduced in this Blog Update.
Above is a massive "Gantry Crane working the manufacturing Plant of ...
CONCRETE TECHNOLOGY CORPORATION ...
Concrete Beam Nameplate
Acceptance - APPROVED FOR SHIPMENT - by Washington State Department of Transportation - of a huge CONCRETE BEAM manufactured by CONCRETE TECHNOLOGY CORP.
In manufacturing of massive structural concrete beams, steel rods protruding from the Concrete Beam are known as "RE BARS"
RE BARS = Reinforcing Bars, an integral part of virtually all Structural Concrete creations.
Such construction methods are found in Sky Scraper Buildings, River and Freeway Bridges (SEATTLE's FLOATING BRIDGES are manufactured from CONCRETE), and ...
...during World War Two, many ships and barges were manufactured from CONCRETE !
...example of large structural Concrete Shapes laced with RE BAR Steel Rods.
Gantry Cranes of a design and manufacture by my old employer, Star Iron and Steel.

As an aside ...
Employed by LOCKHEED AIRCRAFT CORPORATION, Crane Division, SEATTLE, Washington - during my years before employment by SIS, we designed, built, and supervised installation of the TRAVELING BRIDGE CRANE for the MISSILE ASSEMBLY BUILDING at CAPE CANAVERAL (KENNEDY SPACE CENTER), Florida.
This CRANE was developed to assemble and load the SATURN ROCKET on the CRAWLER for the many MOON MISSIONS. This Crane Statistics are:
300 TON LIFT CAPACITY - 150 Tonnes on each of two TROLLEYS.
300 FOOT CLEAR SPAN between the two main TRAVEL ASSEMBLIES
300 FOOT HIGH installation in the massive MAB - MISSILE ASSEMBLY BUILDING
... all before and without computer assistance ...
....with an accuracy of 1 / 64 inch at maximum load and reach ; i.e., 300 ton at 3oo feet elevation !

The above image is a good rendering of a CONTAINER PORT Activity.
Center distant sits an ocean going CONTAINER SHIP ... Containers being OFF - LOADED from the Ship by Traveling Horizontal Boom CONTAINER CRANE in the act of carrying a container to the waiting dock transporter parked between the legs of Container Crane.
The Shore side transporter can be a simple Highway Flatbed Trailer, a Mobile Container Transporter _ which is DRIVEN to any spot in the Container Yard, or on a railroad car equipped to receive containers.
Containers loaded on specially designed flatbed railroad cars. Such cars join up to 100 similar flatbed railroad cars for transport from TACOMA, Washington to an East Coast Container port (called the LAND BRIDGE), where the containers are re-loaded on a Container Ship destined for a Container Port across another Ocean.
The LAND BRIDGE Concept saves time (Months) and $$ moving Containers from around the World across the USA by RAIL instead of through the Panama Canal or around Cape Horn.
Mobile Traveling Gantry Crane.
This steerable heavy lift vehicle has found employment in Container Terminals, in Marinas - to lift and transport BOATS - , and even in the CONCRETE BEAM Storage yard (see 6th image from the top above).
Mobile Container Transporter / Stacker.
This vehicle has an over-the-shoulder BOOM mounted "SPREADER". The SPREADER latches on to the top of the CONTAINER which is carried cantilevered in front of the driver.
In addition to good driver visibility, this equipment, rated at 99,000 pound capacity, handles 48 - ton loaded containers.
The above vehicle is a "Fork Lift" design Container Transporter / Stacker.
Intended for light load duty, this machine handles ONLY "Empty" or lightly loaded Containers.
Level-Luffing Slewing (Rotating) Traveling Gantry Cranes:
As the LOAD is LUFFED IN or OUT (moved closer or away) from the Crane, it (the load) remains at the same elevation automatically. A popular concept some 75 years ago.
A Container Trailer.
The CONTAINER Terminal imaged in this Blog Update was "WUT".
TACOMA claims "ownership" of the world -famous Mount RAINIER ... and with good reason.

Do not have an agenda to continuing our Walk ... at the moment.
Must once again dally ... awaiting next month Social Security $$ to catch up.
Previous difficulties reported threw us a major limitation.
We are recovering, but with caution.
