Gradall Forklift Parts - During the period when World War II created a scarcity of workers, the legendary Gradall excavator was founded in the 1940s as the brainchild of two brothers Koop and Ray Ferwerda. The brothers faced the problems of a depleted labor force due to the war. As partners in their Cleveland, Hayward construction business known as Ferwerda-Werba-Ferwerda they lacked the existing workers to do the delicate work of finishing and grading on their interstate projects. The Ferwerda brothers opted to make a machine that would 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 affixed over a second-hand truck. A telescopic cylinder moved the beams forward and backward which enabled the fixed blade at the end of the beams to push or pull dirt. Before long enhancing the initial design, the brothers built a triangular boom to add more strength. Moreover, they added a tilt cylinder that let the boom turn 45 degrees in either direction. A cylinder was positioned at the rear of the boom, powering a long push rod to allow the equipment to be outfitted with either a blade or a bucket attachment.
The year 1992 marked a significant year for Gradall with their launch of XL Series hydraulics, the most dramatic change in the company's excavators since their invention. These top-of-the-line hydraulics systems enabled Gradall excavators to provide high productivity and comparable power on a realistic level to traditional excavators. The XL Series ended the initial Gradall equipment power drawn from low pressure hydraulics and gear pumps. These conventional systems successfully handled grading and finishing work but had a difficult time competing for high productivity tasks.
The new XL Series Gradall excavators proved a remarkable increase in their lifting and digging ability. These models were manufactured together with a piston pump, high-pressure hydraulics system that showed immense improvements in boom and bucket breakout forces. The XL Series hydraulics system was even developed with a load-sensing capability. Traditional excavators make use of an operator to select a working-mode; where the Gradall system can automatically adjust the hydraulic power for the job at hand. This makes the operator's overall work easier and even conserves fuel at the same time.
As soon as the new XL Series hydraulics reached the market, Gradall was thrust into the extremely competitive industrial machinery market which are meant to deal with excavating, demolition, pavement removal and different 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 work in low overhead areas and to better position attachments.
