Gradall Forklift Parts

During the period when WWII caused a scarcity of laborers, the legendary Gradall excavator was born in the 1940s as the idea of two brothers Ray and Koop Ferwerda. The brothers faced the problems of a depleted workforce because of the war. As partners in their Cleveland, Ohio construction company called Ferwerda-Werba-Ferwerda they lacked the available laborers to do the delicate work of finishing and grading on their interstate projects. The Ferwerda brothers chose to build a machine that will save their business by making the slope grading work less manual, easier and more efficient. Their very first design model was a machine with two beams set on a rotating platform which was attached on top of a second-hand truck. A telescopic cylinder moved the beams back and forth which enabled the fixed blade at the end of the beams to pull or push dirt. Soon improving the very first design, the brothers built a triangular boom to be able to add more strength. Furthermore, they added a tilt cylinder that let the boom turn 45 degrees in both directions. A cylinder was positioned at the back of the boom, powering a long push rod to allow the machinery to be equipped with either a bucket or a blade attachment. Gradall introduced in 1992, with the introduction of the new XL Series hydraulics, the most innovative adjustment in their equipment 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 ended the first Gradall equipment power drawn from gear pumps and low pressure hydraulics. These conventional systems successfully handled grading and finishing work but had a difficult time competing for high productivity work. The new XL Series Gradall excavators proved a remarkable increase in their digging and lifting ability. These versions were made along with a piston pump, high-pressure hydraulics system that showed great improvements in boom and bucket breakout forces. The XL Series hydraulics system was also developed together with a load-sensing capability. Conventional excavators make use of an operator to pick a working-mode; where the Gradall system can automatically adjust the hydraulic power intended for the task at hand. This makes the operator's overall task easier and also saves fuel at the same time. When their XL Series hydraulics came onto the market, Gradall was essentially thrust into the highly competitive market of machinery designed to tackle demolition, pavement removal, excavating and other industrial work. Marketability was further improved with their telescoping boom because of its exclusive ability to work in low overhead areas and to better position attachments.

Alternators

An alternator is actually a machine that changes mechanical energy into electric energy. It does this in the form of an electric current. In principal, an AC electric generator could also be called an alternator. The word normally refers to a small, rotating machine driven by automotive and different internal combustion engines. Alternators that are placed in power stations and...

Brakes

A brake wherein the friction is provided by a set of brake pads or brake shoes that press against a rotating drum shaped unit referred to as a brake drum. There are several particular differences between brake drum types. A "brake drum" is usually the explanation provided if shoes press on the inner exterior of the drum. A "clasp brake"...

Carriage Rollers

Carriage rollers are specifically designed bearings that are used on lift masts so as to help them work in tough environmental conditions. Lift masts are normally subjected to oscillations, shocks, high dynamic and vibrations and static loads. This equipment is regularly exposed to environmental influences such as cold, heat, dust, contamination, aggressive ambient air and moisture. Thus, the lift masts'...

Control Valves

Automatic control systems were primarily established over two thousand years ago. The ancient water clock of Ktesibios in Alexandria Egypt dating to the third century B.C. is believed to be the very first feedback control equipment on record. This particular clock kept time by regulating the water level within a vessel and the water flow from the vessel. A common...

Controllers

Forklifts are accessible in several load capacities and different models. Most forklifts in a regular warehouse situation have load capacities between 1-5 tons. Larger scale models are utilized for heavier loads, such as loading shipping containers, may have up to fifty tons lift capacity. The operator can make use of a control to raise and lower the blades, that can...

Differentials

A mechanical machine which can transmit rotation and torque through three shafts is called a differential. Sometimes but not all the time the differential will employ gears and would work in two ways: in cars, it provides two outputs and receives one input. The other way a differential works is to put together two inputs to produce an output that...

Drive Axles

The piece of equipment that is elastically fastened to the frame of the vehicle with a lift mast is known as the lift truck drive axle. The lift mast affixes to the drive axle and could be inclined, by at least one tilting cylinder, round the drive axle's axial centerline. Forward bearing parts together with rear bearing parts of a...
