Gradall Telehandlers San Diego

The famous Gradall excavator traces its roots back to the beginning of the 1940s. During this time, World War II had caused a shortage of laborers as most of the young men went away to fight the war. This decrease in the work force brought a huge need for the delicate work of grading and finishing highway projects.



A Cleveland, Ohio construction company referred to as Ferwerda-Werba-Ferwerda experienced this particular problem 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 one of the major highway contractors in the state of Ohio. The Ferwerdas' set out to build a machinery which will save both their company and their livelihoods by making a model that would do what had before been manual slope work. This invention was to offset the gap left in the worksite when so many men had joined the army.



The brothers initially invented a device that had 2 beams set on a rotating platform, that was attached on top of a second-hand truck. They used a telescopic cylinder 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 made a triangular boom to produce more strength. Next, they added a tilt cylinder that enabled the boom to rotate 45 degrees in either direction. This new model can be equipped with either a bucket or a blade 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 completed.



Many digging buckets became available on the market not long later. These buckets in sizes varying from 15 inch, 24 inch, 36 inch and 60 inch buckets. There was also a 47 inch heavy-duty pavement removal bucket that was available too.
