A Brief History of Cranes

For thousands of years mankind has sought new ways to lift heavy things. There is evidence of the world’s first ever crane-like device being used to raise building stones in Greece around 500 BC. Cranes first appeared in literature in the writings of Aristotle about 200 years later.



The Romans expanded the Greek concept of a combined pulley and jib, and continued to modify it from a 3-pulley to a multi-pulley design to lift heavier loads.



Power for these early cranes was sheer human strength. The largest early cranes, with multiple work crews and complex rope-and-pulley arrangements, were capable of lifting architectural features, like cap stones weighing over 55 tons.

The Middle Ages And Renaissance

The next great advance in crane technology came during the Middle Ages when treadwheel cranes were used to make vertical lifts in industrial settings like mines and harbors, as well as in the construction of the great cathedrals.



As the name implies, the “treadwheel” was powered by an individual or several workers walking within a large wheel, much the way a hamster’s exercise wheel works. The treadwheel crane is mentioned in literature as early as 1225 AD, and the use of flywheels to ensure a smooth lift and eliminate “dead spots” was documented as early as 1123 AD. Most early cranes were designed primarily for vertical movement, with only limited lateral movement provided by guide ropes.



While Renaissance era cranes became more complex, requiring increased coordination and discipline among work crews, they continued to be plagued by the mechanical limitations of their predecessors: limited lateral control, uneven application of force, and extreme stresses on ropes.

The Industrial Era

The introduction of iron and steel to the industrial environment did much to help bring crane technology into the modern age. Equally important was the replacement of human power, first with steam, and then later with diesel, electrical motors, and modern hydraulics. Railroads harnessed the power of steam to power cranes on “wreck trains”, used to lift derailed locomotives and rolling stock back onto the rails.



Steam powered gantry cranes were used in the construction of locomotives as early as the 1870s, moving heavy boilers, fireboxes, and other components above the manufacturing floor and lowering them into place.

Anatomy of a CAT Forklift

CAT Forklifts have many moving parts and pieces that allow the forklift to operate properly. Understanding the terminology of the lift truck parts and anatomy of a forklift is important for effective communication with others while on the job.

CAT Forklift Mast

The forklift mast is the raised vertical support that allows loads to be raised and lowered. For most forklifts, the mast is designed toward the front of a forklift and directly in the forklift operator’s line of vision.



Forklift masts come with various sections that elevate or lower the fork carriage along with the forks. These include:

• Duplex: Two mast stages
• Triplex: Three mast stages
• Quad: Four mast sections

When selecting a forklift, it is important to familiarize yourself with the different features and terminology of a forklift mast: the mast’s lift height, the free lift height and the extended height and the lowered height. This will allow you to select a forklift that is designed to fulfill the specific needs of your applications.

For more information on forklift masts, read our article Forklift Mast Types.

CAT Forklift Hydraulic Lift Cylinder

The forklift lift cylinder powers the vertical movement of the mast, or the raising or lowering of the forklift carriage and the forks. The lift cylinder is generally hydraulically powered and is a single-acting hydraulic cylinder, meaning it pushes in one direction.

CAT Forklift Tilt Cylinder

Similar to the lift cylinder, the tilt cylinder controls movement for operation purposes. The key difference is that the tilt cylinder controls the tilt movement of the carriage and the angle of the forks relative to the ground.

CAT Forklift Carriage

The carriage is a platform located in front of the forklift mast that is used to mount objects to be controlled by the mast. This includes the forks of the forklift, the load backrest and other features of a forklift truck that come in direct contact with the loads.

CAT Forklift Forks

Also known as the tynes, the forks on a forklift are used to make direct contact with a load for transport. They are attached to the forklift carriage and are designed to carry a load from the bottom. Forklift forks come in all shapes and sizes.



There is a wide variety of fork types available for various applications. Standard ITA forks are the most common type of forklift forks, but they too come in various widths, lengths and shapes.

Is the Catalytic Converter Important? How Catalytic Converters Work

If you’re interested in vehicles as well as keeping our Earth safe, you may be interested in learning more about catalytic converters and how these important devices help to combat against pollution. These devices are a great way to help keep the air around us clean. While this is a hot topic, many people have questions about the use of catalytic converters. Take a look at the following information to learn more about catalytic converters.

What is a catalytic converter?

A catalytic converter is a device that helps to turn toxic byproducts found in an engine into less toxic substances through the use of chemical reactions.



As a car runs, the catalytic converter turns pollutants into less harmful substances before they leave a vehicle through the exhaust pipe. This can help to clean up the air significantly!

Are catalytic converters only found in standard automobiles?

No! While they are found in standard automobiles, they are also in many other machines. This includes buses, trucks, motorcycles, and forklifts, just to name a few. Think of all the vehicles that exist and how much pollution they cause. To combat the pollution, many machines utilize catalytic converters.

Catalytic converter fail?

Yes! There can be a variety of issues with a catalytic converter. For example, a converter can become clogged. A bad exhaust valve on the engine can also cause the converter to work incorrectly. When it fails, the converter won’t be working correctly to combat toxins. If you feel your catalytic converter has failed, it’s important to take your vehicle to a mechanic in order to get it checked out. This is a part that needs to be replaced, if broken.

What would happen if these devices didn’t exist?

Even more harmful pollution would enter our air, making the air clean and unhealthy for us to breathe. Catalytic converters are just one way to keep the air cleaner. Many other products and devices will continue to be researched and developed in the future in order to make even more changes for the Earth.

Under federal law, catalytic converters may not be removed and replaced with "converter replacement pipes" by any person!

Catalytic converters are devices that are found in a vehicle’s engine and help to turn toxic substances into less harmful pollutants. This can help to keep the air cleaner so that we are breathing in safe air when going about our everyday lives. In order for these devices to work correctly and safety, there are important catalytic converters laws. Take a look at the following information to learn more about the use of these devices.

Catalytic converter guidelines have been in place since 1987. These laws were officially outlined by the U.S. Environmental Protection Agency. These laws put in place outline how the converters must be designed, tested and manufactured.

Military Construction Equipment

While reporters in the field seek to give TV viewers at home a clearer picture of the events that lead to victory or defeat in a wartime setting., those reporters seldom cover the path taken by military construction equipment. Sometimes, though, the enemy forces do make note of that path. Sometimes the enemy forces do use their weapons against military construction or convoy equipment.



Sometimes that enemy force proves to be a deadly force. Then the enemy forces remind the TV viewers about the “behind-the-scenes” acts of courage that can play an important part in any planned military operation.The makers of military construction equipment have joined forces with the U.S. Department of Agriculture. Together, those two groups plan to discover and evaluate new fluids, fluids that can expand the number of conditions in which military construction equipment functions efficiently.

At the present time, the joint investigation has chosen to focus on bio-based hydraulic fluids. Such fluids are made from vegetable oils. Farmers who grow rapeseeds, sunflowers, corn, soybeans, canola plants, or coconuts applaud any acceptance of bio-based hydraulic fluids. Meanwhile, the makers of military construction equipment evaluate the lubrication abilities possessed by those same fluids.



The makers of military construction equipment appreciate the range of conditions in which their equipment needs to perform. By the same token, members of the military demand optimal performance from all manner of purchased construction equipment. The success of one military operation could well depend on the efficient operation of bulldozers, scapers, graders, loaders and cranes.

Each of those various pieces of equipment must be tested in a field setting. Evaluation of the test results should aid assessment of the important characteristics displayed by bio-based hydraulic fluids. Evaluation of the tested military construction equipment should yield measurements for three top-priority features, three of the features most-desired by users of construction equipment.



What are those features? One is coating thickness, the amount of lubricant that sticks to the moving parts on the construction equipment. A second feature is viscosity, the degree to which the lubricant resists changes to its form. The third feature is specific gravity, a measurement that is really a comparison. The specific density of a hydraulic fluid indicates how its density compares to the density of water.

Why does the military need to carry-out field tests when measuring the coating thickness, viscosity or specific gravity of bio-based hydraulic fluids? Can’t the appropriate personnel evaluate the performance of military construction equipment in a laboratory setting? No, the combination of conditions in the laboratory can not duplicate properly the combination of conditions that a fighting force might find in the field.



There, the temperatures might rise or fall precipitously. There, moisture of other elements in the air might act to diminish the performance of a less-than-perfect hydraulic fluid.

That is why the military needs to schedule field tests on any military construction equipment, when the lubrication of that equipment depends, for the first time, on bio-based hydraulic fluids. The military can not deny the apparent economic benefits associated with bio-based hydraulic fluids. Yet military leaders in the U.S. want some assurance that unforeseen problems will not eat-up any money saved by a switch from petroleum-based to bio-based hydraulic fluids. Many American farmers hope that leaders in the U.S. military will gain that assurance by examining the results from planned field tests.

What type of Heavy Equipment FAQ are mainly based on?

The Heavy equipment FAQ are mostly based on the worth, how the quality of the heavy equipment would be and most probably the best price that could be paid on that heavy equipment. Most of the construction business oriented people try to get clarified on their doubts about the heavy equipments they purchase or most probably they may be clearing out with the problems they face with their equipments. They may need to move their heavy equipments from one country to another, so they may be in need of many questions like say the import and export duty they have to pay on, the maximum shipping charge and so on.



The term heavy equipment refers to large construction equipment such as back hoes, excavators, loaders, bulldozers, graders and much more. The People who have doubts on the usage, or any other clarification about the heavy equipments may be the part of the FAQ to the general experts on heavy equipments. One such FAQ on heavy equipment is as, why there is a need for used heavy equipment appraisals.
