Gradall Forklift Parts - Throughout the time when WWII created a scarcity of workers, the legendary Gradall excavator was founded in the 1940s as the creation of two brothers Ray and Koop Ferwerda. Partners in a Cleveland, Ohio construction business known as Ferwerda-Werba-Ferwerda, the brothers faced a huge dilemma when numerous men left the workforce and signed up in the military, depleting existing workers for the delicate finishing work and grading on highway projects. The Ferwerda brothers decided to make an equipment which would save their business by making the slope grading work more efficient, less manual and easier.
The very first excavator prototype consisted of a machine with two industrial beams on a rotating platform fixed to a second-hand truck. There was a telescopic cylinder which was utilized to move the beams backward and forward. This allowed the fixed blade at the far end of the beams to pull or push the dirt. Soon improving the initial design, the brothers made a triangular boom so as to add more strength. Also, they added a tilt cylinder which 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 machinery to be outfitted with either a bucket or a blade attachment.
The year 1992 marked a significant year for Gradall with their launch of XL Series hydraulics, the most remarkable 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 put an end to the first Gradall equipment power drawn from gear pumps and low pressure hydraulics. These traditional systems efficiently handled finishing work and grading but had a hard time competing for high productivity work.
The new XL Series Gradall excavators proved a significant increase in their digging and lifting ability. These versions were manufactured with a piston pump, high-pressure hydraulics system that showed huge improvements in boom and bucket breakout forces. The XL Series hydraulics system was likewise developed along with a load-sensing capability. Conventional excavators utilize an operator so as to choose 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 task easier and likewise saves fuel at the same time.
As soon as their XL Series hydraulics came onto the market, Gradall was essentially thrust into the highly competitive market of equipment meant to tackle demolition, pavement removal, excavating as well as different industrial tasks. Marketability was further improved with their telescoping boom due to its exclusive ability to work in low overhead areas and to better position attachments.
