Gradall Telehandlers Tucson

The famous Gradall excavator traces its roots back to the beginning of the 1940s. During this time, WWII had caused a scarcity of laborers because most of the young men went away to war. This decrease in the labor force brought a huge demand for the delicate work of grading and finishing highway projects.



A Cleveland, Ohio construction company referred to as Ferwerda-Werba-Ferwerda faced this particular dilemma first hand. Two brothers, Ray and Koop Ferwerda had moved to the United States from the Netherlands. They were partners in the firm that had become among the leading highway contractors in the state of Ohio. The Ferwerdas' started to build a machinery that would save both their livelihoods and their company by making a unit that would do what had before been physical slope work. This invention was to offset the gap left in the workplace when so many men had joined the military.



The brothers first created an apparatus which had 2 beams set on a rotating platform, that was fixed on top of a second-hand truck. They utilized a telescopic cylinder in order to move the beams out and in. This enabled the fixed blade at the end of the beams to push or pull dirt.



After a short time, the Ferwerda brothers improved on their initial design. They created a triangular boom to produce more strength. After that, they added a tilt cylinder which enabled the boom to turn 45 degrees in either direction. This new model can be equipped with either a blade or a bucket and the attachment movement was made possible by placing a cylinder at the rear of the boom. This design powered a long push rod and allowed a lot of work to be finished.



Many digging buckets were introduced to the market not long later. These buckets in sizes ranging from 15 inch, 24 inch, 36 inch and 60 inch buckets. There was also a 47 inch heavy-duty pavement removal bucket which was also offered.
