Gradall Forklift Parts - During the time when WWII created a shortage of workers, the well-known Gradall excavator was born in the 1940s as the creation of two brothers Ray and Koop Ferwerda. Partners in a Cleveland, Ohio construction business called Ferwerda-Werba-Ferwerda, the brothers faced a huge predicament when a lot of men left the labor force and signed up in the military, depleting existing laborers for the delicate grading and finishing work on highway projects. The Ferwerda brothers opted to make an equipment which would save their company by making the slope grading job more efficient, less manual and easier.
The first excavator prototype consisted of a device with two industrial beams on a rotating platform fixed to a used truck. There was a telescopic cylinder that was utilized to move the beams backward and forward. This allowed the fixed blade at the far end of the beams to push or pull the dirt. Before long enhancing the very first design, the brothers made a triangular boom in order to add more strength. What's more, 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 machine 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 innovative adjustment in their machines since their invention. This new system of top-of-the-line hydraulics allowed the Gradall excavator to provide comparable power and high productivity to the more conventional excavators. The XL Series put an end to the first 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 jobs.
The new XL Series Gradall excavators proved a significant increase in their digging and lifting ability. These versions were manufactured together with a piston pump, high-pressure hydraulics system which showed great improvements in boom and bucket breakout forces. The XL Series hydraulics system was even developed together with a load-sensing capability. Conventional excavators make use of an operator so as to select a working-mode; where the Gradall system can automatically adjust the hydraulic power for the work at hand. This makes the operator's overall work easier and even saves fuel simultaneously.
As soon as their XL Series hydraulics came onto the market, Gradall was essentially thrust into the highly competitive market of machinery designed to tackle demolition, pavement removal, excavating and several industrial work. Marketability was further improved with their telescoping boom because of its exclusive ability to better position attachments and to work in low overhead areas.
