Gradall Forklift Parts - All through the period when World War II caused a shortage of laborers, the famous Gradall excavator was founded in the 1940s as the brainchild of two brothers Koop and Ray Ferwerda. Partners in a Cleveland, Ohio construction company called Ferwerda-Werba-Ferwerda, the brothers faced a huge predicament when lots of men left the workforce and signed up in the military, depleting existing workers for the delicate grading and finishing work on highway projects. The Ferwerda brothers decided to build a machine which will save their business by making the slope grading task easier, more efficient and less manual.
Their first design prototype was a machine with two beams set on a rotating platform which was attached over a second-hand truck. A telescopic cylinder moved the beams back and forth that enabled the fixed blade at the end of the beams to pull or push dirt. Shortly enhancing the first design, the brothers built a triangular boom to be able to add more strength. As well, they added a tilt cylinder which let the boom rotate 45 degrees in either direction. A cylinder was positioned at the back of the boom, powering a long push rod to enable the machinery to be outfitted with either a blade or a bucket attachment.
Gradall launched in the year 1992, with the introduction of the new XL Series hydraulics, the most ground-breaking adjustment in their machinery since their creation. This new system of top-of-the-line hydraulics enabled the Gradall excavator to provide high productivity and comparable power to the more traditional excavators. The XL Series put an end to the first Gradall equipment power drawn from gear pumps and low pressure hydraulics. These traditional systems efficiently handled grading and finishing work but had a hard time competing for high productivity jobs.
The new XL Series Gradall excavators proved a significant increase in their lifting and digging ability. These models were manufactured along with a piston pump, high-pressure hydraulics system which showed immense improvements in boom and bucket breakout forces. The XL Series hydraulics system was also developed together with a load-sensing capability. Conventional excavators use an operator so as to pick a working-mode; where the Gradall system can automatically adjust the hydraulic power intended for the work at hand. This makes the operator's general job easier and also saves fuel simultaneously.
Once the new XL Series hydraulics became available in the market, Gradall was thrust into the extremely competitive industrial machine market that are meant to tackle demolition, pavement removal, excavating as well as several industrial tasks. The introduction of the new telescoping boom helped to further improve the excavator's marketability. The telescoping boom gives the excavator the ability to better position attachments and to work in low overhead areas.
