Support for
Other Transportation
As various eras of transportation
gained prominence, the lifting industry and its machines provided support
systems. Water was the first medium of transport whether small craft on
the rivers of the Middle and Far East, or ships upon the Mediterranean
and Indian Seas. Naturally, the hoisting of sails made travelling long distances
easier and oars were the levers of motion. Where no waterways existed, they
had to be introduced in the way of canals. Lifting machines dug the canals,
but once water flowed within, craft could not be moved uphill! Solving
the elevation of barges and other canal craft brought some of the industry's
most innovative lifting -- the shiplifts -- and, not to be forgotten -- drydocks
that lifted ships completely out of the water! As luxury ships housed
hundreds, even thousands of passengers, they became mini-cities requiring
transportation between levels. Rail and train travel competed on land,
century after century, through all power eras. However, even the heaviest
rail cars had to be lifted for maintenance by hydraulic power. Automobiles
were also raised for maintenance, but by far the greatest problem associated
with cars was their overabundance in urban centers. Storage schemes proliferated
to alleviate serious congestion problems. As will be seen in other galleries, --
Escalators and Moving Sidewalks -- during the era of air travel, as aircraft
became larger, they had to be dispersed in more widely separated areas
for embarkation. This necessitated the continuous movement of people between
planes and land transport. Escalators, moving sidewalks and shuttles
helped alleviate this problem.
