Gradall forklift series#
The year 1992 marked a momentous year for Gradall with their launch of XL Series hydraulics, the most dramatic change in the company's excavators ever since their creation. A cylinder was placed at the back of the boom, powering a long push rod to allow the machinery to be equipped with either a blade or a bucket attachment. What's more, they added a tilt cylinder that let the boom turn 45 degrees in both directions. Soon enhancing the very first design, the brothers built a triangular boom so as to add more strength. A telescopic cylinder moved the beams back and forth that enabled the fixed blade at the end of the beams to pull or push dirt. Their initial design prototype was a device with two beams set on a rotating platform which was attached over a used truck.

The Ferwerda brothers chose to build an equipment which will save their business by making the slope grading job more efficient, less manual and easier. Partners in a Cleveland, Ohio construction company referred to as Ferwerda-Werba-Ferwerda, the brothers faced a huge dilemma when numerous men left the workforce and joined the military, depleting available workers for the delicate grading and finishing work on highway projects. The telescoping boom gives the excavator the ability to better position attachments and to work in low overhead areas.Gradall Forklift Parts - Through the period when WWII caused a shortage of workers, the famous Gradall excavator was established in the 1940s as the brainchild of two brothers Ray and Koop Ferwerda.
The introduction of the new telescoping boom helped to further enhance the excavator's marketability. Once the new XL Series hydraulics reached the market, Gradall was thrust into the very competitive industrial machinery market that are designed to deal with demolition, pavement removal, excavating and other industrial jobs. This makes the operator's overall job easier and even saves fuel at the same time. Traditional excavators utilize an operator to select a working-mode where the Gradall system could automatically adjust the hydraulic power intended for the job at hand. The XL Series hydraulics system was even developed along with a load-sensing capability. With this series, the models were made together with a piston pump, high-pressure system of hydraulics that showed marked improvement in boom and bucket breakout forces. Gradall's new XL Series excavators showed more ability to dig and lift materials. These conventional systems efficiently handled finishing work and grading but had a difficult time competing for high productivity jobs. The XL Series ended the first Gradall equipment power drawn from gear pumps and low pressure hydraulics. This new system of top-of-the-line hydraulics allowed the Gradall excavator to provide high productivity and comparable power to the more traditional excavators.
Gradall introduced in 1992, with the introduction of the new XL Series hydraulics, the most ground-breaking adjustment in their equipment ever since their creation. A cylinder was placed at the rear of the boom, powering a long push rod to enable the equipment to be equipped with either a bucket or a blade attachment. Furthermore, they added a tilt cylinder that let the boom rotate 45 degrees in either direction.
Shortly enhancing the first design, the brothers made a triangular boom to add more strength. A telescopic cylinder moved the beams back and forth that allowed the fixed blade at the end of the beams to push or pull dirt. Their initial design prototype was a machine with two beams set on a rotating platform which was attached atop a used truck. The Ferwerda brothers chose to make an equipment which would save their company by making the slope grading job easier, more efficient and less manual. As partners in their Cleveland, Ohio construction company known as Ferwerda-Werba-Ferwerda they lacked the available workers so as to carry out the delicate work of grading and finishing on their freeway projects.
The brothers faced the problems of a depleted workforce due to the war. During the time when WWII caused a scarcity of laborers, the well-known Gradall excavator was established in the 1940s as the idea of two brothers Koop and Ray Ferwerda.
