Gradall Forklift Part - The Gradall excavator was the creation of two brothers Koop and ray Ferwerda. The excavator was created In the 1940's all through WWII, when there was a shortage of workers. The brothers faced the problems of a depleted workforce due to the war. As partners in their Cleveland, Ohio construction company called Ferwerda-Werba-Ferwerda they lacked the existing laborers so as to do the delicate job of finishing and grading on their freeway projects. The Ferwerda brothers opted to make a machine that will save their company by making the slope grading task more efficient, less manual and easier.
Their very first design prototype was a machine with two beams set on a rotating platform that was attached over a used truck. A telescopic cylinder moved the beams back and forth which allowed the fixed blade at the end of the beams to push or pull dirt. Before long improving the initial design, the brothers built a triangular boom in order to add more strength. As well, they added a tilt cylinder that let the boom turn 45 degrees in either direction. A cylinder was placed at the rear 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 1992, with the introduction of the new XL Series hydraulics, the most innovative adjustment in their machinery ever since their invention. This new system of top-of-the-line hydraulics enabled the Gradall excavator to provide comparable power and high productivity to the more conventional excavators. The XL Series ended the initial Gradall equipment power drawn from gear pumps and low pressure hydraulics. These traditional systems successfully handled finishing work and grading but had a difficult time competing for high productivity work.
The new XL Series Gradall excavators proved a significant increase in their digging and lifting ability. These models were made along with a piston pump, high-pressure hydraulics system that showed immense improvements in boom and bucket breakout forces. The XL Series hydraulics system was also developed with a load-sensing capability. Traditional excavators utilize an operator so as to pick a working-mode; where the Gradall system could automatically adjust the hydraulic power intended for the task at hand. This makes the operator's overall work easier and likewise saves fuel simultaneously.
When their XL Series hydraulics came onto the market, Gradall was basically thrust into the highly competitive market of machines meant to deal with demolition, pavement removal, excavating as well as different industrial tasks. Marketability was further enhanced with their telescoping boom due to its exclusive ability to work in low overhead areas and to better position attachments.
