Wolff Cranes Salem

The Evolution into Hydraulics

The Second World War forced much of society to improve overall resourcefulness. During this specific period in time, the design and development of cranes evolved significantly. These industrial machines changed the face of the construction business.



The very first hydraulic crane was built in 1946 by crane company F. Taylor & Sons. This very first unit was not able to slew or luff and was just used by the company. When it joined with Coles in the year 1959, this model opened up the doors for a 50 and 42 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 that were lifted and lowered by a hydraulic pump. When the business was unable to utilize army vehicles as chassis for the machinery, they started production for designing their own mobile hydraulic cranes.



The 1950s offered cranes that were heralded as incredible equipments that were capable of rebuilding what bombs dropped in the war had destroyed. The cranes were responsible for helping put together cities, countries and individual homes. Hydraulic systems became designed more and more complicated. The pumps and gear systems can be powered while the trucks remained immobile. Businesses like for example Hydrauliska Instustri AB made the very first truck loader crane appearance on the market.



In 1952, the A2 crane was introduced. This particular unit was a crane mounted on the back of Chevrolet truck. It was complete with hydraulic lifting cylinders and a hooked winch. This particular loader crane started a huge trend in the business. A company situated within Bremen, referred to as Atlas Weyhausen began manufacturing similar versions of this equipment.



Cranes immediately after the war were becoming more advanced. Various companies and manufacturers making the winches developed accurate telescopic booms, and the hydraulic pumps were improved and using different materials in order to change the way the crane was developed.
