The Gradall excavator was the idea of two brothers Ray and Koop Ferwerda. The excavator was established In the 1940's throughout WWII, when there was a scarcity of labourers. Partners in a Cleveland, Ohio construction business known as Ferwerda-Werba-Ferwerda, the brothers faced a huge predicament when numerous men left the labor force and joined the military, depleting existing workers for the delicate grading and finishing work on highway projects. The Ferwerda brothers decided to make an equipment that will save their business by making the slope grading task less manual, easier and more efficient. 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 used to move the beams back and forth. This allowed the fixed blade at the far end of the beams to pull or push the dirt. Before long enhancing the first design, the brothers built a triangular boom so as to add more strength. What's more, they added a tilt cylinder which let the boom turn 45 degrees in both directions. A cylinder was positioned at the rear of the boom, powering a long push rod to enable the equipment to be equipped with either a blade or a bucket attachment. Gradall introduced in the year 1992, with the introduction of the new XL Series hydraulics, the most innovative adjustment in their equipment ever since their invention. This new system of top-of-the-line hydraulics allowed the Gradall excavator to provide high productivity and comparable power to the more conventional excavators. The XL Series put an end to the original Gradall equipment power drawn from low pressure hydraulics and gear pumps. These traditional systems effectively handled finishing work and grading 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 made 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 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 for the task at hand. This makes the operator's whole work easier and likewise saves fuel simultaneously. Once their XL Series hydraulics became available, Gradall was essentially thrust into the highly competitive market of equipment designed to deal with pavement removal, excavation, demolition and various industrial tasks. Marketability was further improved with their telescoping boom due to its exclusive ability to better position attachments and to work in low overhead areas.
