Gradall Forklift Parts

Throughout the time when WWII created a shortage of workers, the legendary Gradall excavator was founded in the 1940s as the brainchild of two brothers Ray and Koop Ferwerda. Partners in a Cleveland, Ohio construction business called Ferwerda-Werba-Ferwerda, the brothers faced a huge dilemma when lots of men left the labor force and joined the military, depleting existing laborers for the delicate grading and finishing work on highway projects. The Ferwerda brothers decided to make a machine which would save their company by making the slope grading task easier, more efficient and less manual.

Their very first design model was a device with two beams set on a rotating platform which was attached on top of a used truck. A telescopic cylinder moved the beams back and forth which allowed the fixed blade at the end of the beams to pull or push dirt. Soon enhancing the very first design, the brothers built a triangular boom to add more strength. What's more, they added a tilt cylinder that let the boom rotate 45 degrees in either direction. A cylinder was positioned at the rear of the boom, powering a long push rod to enable the machine to be equipped with either a blade or a bucket attachment.

Gradall launched in the year 1992, with the introduction of the new XL Series hydraulics, the most innovative adjustment in their machinery ever since their creation. This new system of top-of-the-line hydraulics allowed the Gradall excavator to deliver comparable power and high productivity to the more conventional excavators. The XL Series ended the first Gradall equipment power drawn from low pressure hydraulics and gear pumps. These traditional systems efficiently handled finishing work and grading but had a hard time competing for high productivity tasks.

The new XL Series Gradall excavators proved a significant increase in their lifting and digging ability. These models were made along with a piston pump, high-pressure hydraulics system which showed great improvements in boom and bucket breakout forces. The XL Series hydraulics system was also developed with a load-sensing capability. Traditional excavators use an operator to be able to choose a working-mode; where the Gradall system can automatically adjust the hydraulic power for the work at hand. This makes the operator's general job easier and also saves fuel simultaneously.

Once their XL Series hydraulics came onto the market, Gradall was basically thrust into the highly competitive market of machinery meant to tackle pavement removal, excavation, demolition as well as different industrial tasks. Marketability was further enhanced with their telescoping boom because of its exclusive ability to work in low overhead areas and to better position attachments.

Alternators

A device utilized in order to transform mechanical energy into electrical energy is known as an alternator. It could carry out this function in the form of an electric current. An AC electrical generator can in essence also be termed an alternator. Nevertheless, the word is usually used to refer to a rotating, small device driven by internal combustion engines....

Brakes

A brake drum is in which the friction is supplied by the brake shoes or brake pads. The pads or shoes press up against the rotating brake drum. There are a few various brake drums types with certain specific differences. A "break drum" will normally refer to if either pads or shoes press onto the interior outside of the drum....

Carriage Rollers

Carriage rollers are particularly designed bearings that are used on lift masts in order to help them perform within difficult environmental conditions. Lift masts are often subjected to shocks, oscillations, high dynamic and vibrations and static loads. This apparatus is often exposed to environmental influences such as dust, cold, heat, aggressive ambient air, moisture and contamination. Hence, the lift masts'...

Carriages and Carriage Parts

There are actually 4 sizes of hook type tine carriages rated by the fork carriage hoisting capacity. Hook type blade carriages have been the same. The carriage bar spacing used for Class 1 is about 13 inches and the Class 1 carriage is rated to hold cargo as much as 2000lbs. The Class 2 carriage is rated to hold cargo...

Control Valves

The first automatic control systems were being utilized over two thousand years ago. In Alexandria Egypt, the ancient Ktesibios water clock constructed in the third century is thought to be the first feedback control tool on record. This clock kept time by means of regulating the water level inside a vessel and the water flow from the vessel. A popular...

Controllers

Forklifts are accessible in various load capacities and several units. Most lift trucks in a typical warehouse setting have load capacities between 1-5 tons. Larger scale models are used for heavier loads, like for instance loading shipping containers, may have up to 50 tons lift capacity. The operator can utilize a control so as to lower and raise the blades,...

Differentials

A mechanical machine capable of transmitting torque and rotation through three shafts is referred to as a differential. Every so often but not at all times the differential would utilize gears and would operate in two ways: in vehicles, it receives one input and provides two outputs. The other way a differential works is to combine two inputs to produce...

Drive Axles

The piece of equipment that is elastically affixed to the frame of the vehicle with a lift mast is the lift truck drive axle. The lift mast attaches to the drive axle and could be inclined, by at the very least one tilting cylinder, round the drive axle's axial centerline. Forward bearing components combined with back bearing elements of a...
