The Evolution into Hydraulics
The beginning of WWII forced society to become more creative in general. Even if the development and design of cranes has changed significantly, during this specific time these machinery progressed significantly. These industrial machinery changed the face of the construction industry.
The first hydraulic crane was built in 1946 by crane manufacturer F. Taylor & Sons. This first unit was not able to luff or slew and was only used by the company. When it joined together with Coles in 1959, this unit opened up the doors for a 42 and 50 Series. A Morris W.D. chassis is what the mobile hydraulic crane was initially placed on.
The hydraulic crane by Taylor & Sons operated on a boom powered by a hydraulic pump as well as cylinders which were lowered and lifted by a hydraulic pump. When the company was unable to utilize army vehicles as chassis for the machinery, they started production for designing their own mobile hydraulic cranes.
These first equipments gained a lot of praise and were heralded as amazing equipments. They were supposed to be capable of rebuilding all that was damaged by bombs during the war. The cranes were responsible for helping put together cities, countries and individual houses. Hydraulic systems became designed more and more complicated. The gear and pump systems can be powered while the trucks remained immobile. Companies like for instance Hydrauliska Instustri AB made the very first truck loader crane appearance on the market.
The A2 crane was introduced during 1952. This unit was mounted directly to the rear of a Chevy truck. It was complete with a hooked winch and hydraulic lifting cylinders. This loader crane started a huge trend in the industry. A company located within Bremen, known as Atlas Weyhausen started manufacturing similar versions of this particular machine.
Cranes immediately after the war were becoming more sophisticated. Different businesses and manufacturers making the winches developed accurate telescopic booms, and the hydraulic pumps were improved and using various materials so as to change the way the crane was developed.
