Everything you should know about cranes

All types of cranes are different from each other in many aspects. On the most basic level, there is no external power or machinery required for cranes to function properly. You learn more about this by contacting rigging companies near you also.

On the other hand, other machinery such as the tractor, excavator, and bulldozers require power to operate. This could either come from oil and/or gas.

And in the 1900s, the construction industry used many different equipment. However, cranes were invented later down the line.

What are cranes?

Cranes are machines that are used for heavy load lifting and moving. This could be done for a big number of purposes. For instance, cranes are used in many different industries that include material loading, ship building, manufacturing, and construction.

Nowadays, you can note that cranes are very commonly found along the skylines. This is because they are very necessary for building skyscrapers that we find in our cities.

What are the basic components of cranes?

There are many different types of cranes. However, there are several components that we believe you should know about. The parts that you can mainly find in a crane include the following:

The crane boom

This may be the most obvious part of the crane. A boom is a lengthy arm that can either be fixed or telescopic in nature.

These carry out a wide range of tasks depending on what the purpose of the crane is. Furthermore, booms are considered to be a main/major component of cranes.

Typically, booms are used for lifting, moving, and positioning purposes. Since they life most of the load, they are made of a very sturdy material and can also determine the crane’s reach.


The Jibs are a crystal like lattice structure that you can see at the end of each boom. This type of build helps in the reduction of weight in the front of the boom.

The jobs have are typically fixed in spot. This means that you can neither retract them nor extend them further. Though, some mobile versions tend to have a jib at the end of the boom also for lifting and moving materials.

The main purpose of the jib is to keep the material away from the main support so that it does not hit it while moving.

While Jibs are not always important, they are extra pieces that can further improve the efficiency and working of a crane greatly.

Rotex gear

This refers to the mechanism of gears that are included below the crane cab. These gears help the crane in rotating right and left. While this movement is a simple one, it is very important for the correct working of a crane.

The hook

Lastly, we have the hook. This is the material that attaches itself to the objects that are required to be moved. For instance, hooks would often be attached with containers in shipyards and docks, where they have to be transported around.

Hooks are typically made of either wrought iron or steel. Furthermore, when it comes to heavy duty cranes, these hooks are often forged and treated with heat for strength and durability.


We hope that the above-mentioned information has enriched your knowledge of cranes. Now, if you want to hire or rent a crane service for heavy load moving, start looking for contractors around you today.

Before getting crane truck rentals DC, make sure that the company is fully certified and that the operator has enough experienced. Never hire an unlicensed company because it is against the law to operate cranes without having a proper license or certification.

All about overhead ranes

A number of operations that involve metal fabricating involve the use of overhead cranes. However, a big number of companies do not use them simply because they are unaware of their exact capabilities. So, whenever they get a crane for rent, they end up choosing the wrong crane due to a lack of knowledge. In a big number of instances, overhead cranes are extremely useful and can actually get the work done much quicker.

What is overhead crane?

The overhead bridge crane is the most common type that is used in manufacturing plants and such industries. This is primarily because overhead bridge cranes offer a hook motion along three different axes. For instance, they can not only move up and down, but they also move back and forth, along with side to side motion. As a result of this, these cranes are extremely useful.

Now that we are talking about overhead bridge cranes, let us also briefly discuss gantry cranes. Gantry cranes tend to work in a similar way with one big difference. Gantry cranes are supported on floor unlike overhead cranes.

Where are gantry cranes used?

Gantry cranes are primarily used in industries where transportation of loads is required from one building to another. Furthermore, they are also used when a manufacturer does not have intentions to stay in a single spot for long.

How are cranes classified in the USA?

Well the classification of cranes in the United States may be a little complex for a layman to understand. Basically, the cranes are classified by the Crane Manufacturers Association of America (CMAA). This entity classifies crane into five different categories that include Class A, Class B, Class C, Class D, Class E, and Class F.

In general, Class A covers all the maintenance and installation cranes which require movement of equipment at considerably low speeds. In comparison, Class F, which lies on the other end of the spectrum covers gantry type cranes. These class of cranes handle loads that are significantly heavier.

All the other classes of crane tend to lie in between these major classes.

The safety precautions with overhead cranes

With overhead cranes, there is one biggest safety precaution which says that never ever dare to bring a load on top of anybody’s head. This golden rule is a big concern due to the fact that many companies do not really train their crane operators properly. Usually, crane operators happen to be the lowest paid of the lot.

If at such a site, you will ask any crane operator about the crane’s rated capacity, they will have no answer. This is because they are usually not trained properly. Hence the biggest safety precaution is to let the cranes be operated by trained individuals only.

With that, another safety precaution is for everybody on the site to be wearing helmets along with other personal protective gear. This also applies to the operator of the crane himself, and everybody else.


When it comes to overhead cranes, they are quite complex. Hence, they need a certified operator for their proper operation. Yet a big number of companies do not hire trained operators in order to save their costs. This may even be illegal to some extent. So, security and safety of everybody on the site should be the first priority. In case you are looking to rent a crane for your business/work, reach out to small crane rentals DC near you. However, before you rent the crane, it is very important to do all your homework. Essentially, you should know exactly what your requirements are and what you need the crane for.
