Hulett Ore Unloader History, Technology and Modeling

Hulett Unloaders:

Most Hulett unloaders, starting with the 15-ton machines at Ashtabula, followed the same basic concept, through each installation, at nearly every different dock or location, was unique. The Hulett/Wellman design evolved over time through four 'generations':

1st generation Huletts - 10-ton units (11) built from 1899 to 1903:
The first Huletts were the 4 original steam/hydraulic units at Conneaut, rated at 10-tons capacity per "bite". Around 1902-1903 these machines were retro-fitted with an early type of larry car system; these were commonly called "bucket cars", which held a 10-ton load but had no scales or weighing equipment. Buffalo had 2 similar steam units (BR&P) and 5 electric/hydraulic units (Lackawanna), which followed the original Conneaut design quite closely, except that they were equipped with bucket cars as originally built.

2nd generation Huletts - 10-ton open-truss units (17) built from 1905 to 1909:
Starting in 1905, the Wellman Company engineers, and George Hulett, substantially improved the basic Hulett design to take advantage of complete electrical power and control. The bucket leg was increased in height and the auxiliary arm, or stabilizer, was now placed below the main walking beam, so that they could dig deeper into the holds of ever larger ore boats. The main walking beam was now a partial open-truss construction (forward of the trolley pivot posts) and gave these Huletts the appearance of a dragonfly. The "bucket car" feature was equipped with a separate scale or weighing hopper on some of these open-truss units, where the ore was weighed by an operator who stood in a separate machinery house built on the rear sills of the main girders. The original 5 open-truss Huletts at Gary Indiana in 1907 were the first Huletts that were originally installed with weighing hoppers.

3rd generation Huletts - 15-ton and 17-ton units (44) built from 1909 to 1950:
By 1908, bigger boats and ever increasing demand for ore necessitated another updating of the Hulett design. The new design returned to the original, heavier, girder constructed walking beam as with the original Huletts, because it provided more strength to carry larger capacity 15-ton and later 17-ton buckets. The main base and girders were now much longer than in the open-truss units. Perhaps the most significant improvement, was the refined "larry car" and its new features. First, a separate receiving hopper was now positioned above the larry car traveling rails, holding each "bite" of ore from the bucket. The larry car's capacity was increased to 30 tons or more, and the operators rode right inside the car itself to more quickly and accurately weigh the unloaded ore with scales built as part of the car unit. The operators were also now able to load railroad cars just by stopping above them, being able to see the entire line of cars and tracks located under each unloader. These third generation electric machines, starting with the Ashtabula units, became the "standard" Hulett unloader design for almost all subsequent Hulett installations.

4th generation Huletts - 20-ton units (9) built from 1944 to 1960:
A 20-ton Hulett design was speculated as far back as 1913, but was not seriously considered until the early 1940s, when WW II pushed ore demand to its highest levels ever. The 20-ton units featured a flatter receiving hopper, positioned lower than those on a standard 17-ton Hulett, in order to reduce the time needed to raise the bucket up over the main girders after coming up with a "grab" from a vessel's hold. Apart from this the 20-ton Hulett was nothing more than a "beefed-up" version of a 17-ton machine. These units were heavier, more bulky, and less graceful in their appearance. Seven of the nine 20-ton Huletts were built for U.S. Steel's Gary and Lorain plants, as replacements for their ageing 10-ton open-truss Huletts.
