Top Crane Uses That You Probably Never Knew About

Top Crane Uses That You Probably Never Knew About

When you think of a crane, you might picture a construction crane. This type of machine isn’t limited to construction cranes. There’s a wide range of industries that use a crane.

Cranes are an integral part of activities that involve lifting. Cranes can lift a heavy load from a truck bed onto a flat platform, or vice-versa. Cranes are great for moving materials throughout a warehouse.

Do you want to learn about the different crane uses? Read on to learn about the top crane uses in this crane guide.

Overhead Cranes

An overhead crane enables users to lower, lift or move loads with ease. This type of crane has high lifting capabilities for load movement.

An operator can control an overhead crane manually or through wireless controls. It can also be controlled via a wired pendant station. The station guides the crane’s travel.

What are the benefits of using an overhead crane? It offers increased safety. An overhead crane doesn’t carry the risk that forklifts come with.

Forklifts can drop a load due to imprecise stacking. This can increase the risk of an accident. Overhead crane operators can promote safety by following safety tips.

Mobile Cranes

Mobile cranes allow for the easy transportation of loads to a site. These cranes are mounted on a mobile platform. Most are mounted on a wheeled truck.

Mobile cranes often operate a boom. The boom has a hook that’s suspended by sheaves and wire rope. An engine operates the wire ropes.

Their power allows them to lift heavy objects. These cranes can access sites that other cranes might not be able to access. These are some of the crane benefits that mobile cranes offer.

Telescopic Cranes

A telescopic crane is a type of heavy crane that’s perfect for transporting and moving objects from one place to another. This crane is equipped with height adjustments. This helps to solve any issues related to height.

It uses a hydraulic mechanism to elongate and refract the motion of the boom. The boom consists of several tubes. These tubes are fitted next to each other.

The tubes help to increase the crane’s gross hauling height. They also help to raise and drop objects.

Grapple Cranes

Grapple cranes are the ones you often see harvesting trees in the forest. These are cranes that you might also see at junkyards or landfills. The average American generates 4.9 pounds of garbage per day, so grapple cranes are built to last.

Grapple cranes are versatile and offer precise control. They also improve efficiency. These are some of the crane advantages it offers.

These Are Some of the Most Common Crane Uses

A crane is an indispensable machine. As you read, crane uses vary across different industries. Cranes are the perfect tools for the heavy lifting and moving of objects.

How to Build a Crane

How to Build a Crane

Forecasts show that the global crane and hoist market could reach $4.87 billion by 2028.

Building a crane is not the most complicated process, but it is essential that there are no mistakes. Any oversights in the construction of a crane could result in it collapsing, causing huge amounts of damage.

If you’re interested in the basics of how to build a crane, keep reading.

1. Establish the Location

Making sure the crane is in the most suitable spot is essential. It needs to be in an open space with plenty of room to move, and you should take wind patterns into consideration.

There are also strict placement rules that you must follow. For example, the crane cannot be within 10 feet of power lines.

2. Create the Foundation

Before the crane building can begin a strong foundation is needed to ensure the crane stays stable. The size of the foundation will vary depending on the dimensions of the crane. A rough general size would require a five-foot-deep hole and measure about 30 x 30 feet.

After laying the foundation you should give it a few days to settle before continuing. You’ll want to check the base regularly to be sure it hasn’t sunk at all or settled incorrectly.

If there are any issues the whole foundation may need to be redone. It’s better to make sure it is right from the start to avoid finding out later if the crane collapses.

3. Construct the Initial Tower

The first step of building a crane involves attaching the first mast to the base, usually with anchor bolts that stick out from the substructure. Once secure, you can stack more masts to reach the height needed for the first stage of construction.

Throughout this, and while the crane is in use, the base should be monitored to make sure the load isn’t too heavy and that the elevation is correct.

4. Construct the Slewing Assembly

The slewing assembly consists of a number of components that enable the crane to move in different directions:

• Horizontal jib
• Counter jib
• Cab
• Slewing ring
• Tower top

You can assemble this piece by piece, or if desired it can all be assembled as one part and then lifted onto the initial mast when ready.

5. Adjust the Height

A hydraulic jack along with the top climbing unit makes it possible to lift the slewing assembly while adding new masts. This allows you to increase the overall height of the crane whenever needed.

What to Do After You Build a Crane

Before the crane is used for construction you should carry out a complete inspection and load test. Observing structural elements throughout a load test and re-inspecting after will reveal any issues such as cracks or leaning. It is important to address these immediately.

A licensed technician must also carry out an inspection on any switches, cables, and brakes before use.

These tests may vary for different types of cranes.

Other Crane Building Tips

Cranes are varied, complicated machines, with a lot of different capabilities depending on the type of crane in question.

Now that you know the basics of how to build a crane you might be thinking about investing in one. If that is the case, you’ll want to check out our article about the top factors to consider when buying a crane.

How Do Construction Cranes Work?

How Do Construction Cranes Work?

Have you ever gazed upward at a tall building and wondered how all that heavy material was lifted into its final position? Cranes are a true feat of engineering. Construction cranes can lift upwards of 40,000 pounds at once!

If you have ever wondered how a construction crane works, read on to explore our construction cranes guide.

How Construction Cranes Work

Whether you are curious about knuckle-boom cranes or tower cranes, any crane basically works the same way. Below, we’ll explore some of the basic components that allow cranes to do the important work they do. Any construction cranes buying guide would include cranes with these features.

The Mast

The mast is easily the most recognizable part of any crane. Put simply, it’s the tall part of the crane assembly that sticks straight up into the air. Sometimes, it even resembles the mast of a ship.

Rather than lifting a sail, though, a crane mast raises heavy building materials. Supporting tower cranes are heavy bases that stabilize the cranes. The base for tower cranes can weigh 400,000 pounds.

Not all cranes are supported by a base. Forestry cranes must be mobile in order to be useful for moving lumber.

Gear and Motor

Near or at the top of the mast is the gear and motor assembly. This allows the crane to rotate. Some assemblies are powered by electricity while others are driven by a gas motor.

The lifting ability of a crane isn’t its only asset. A crane must be able to lift and rotate so cargo reaches specific points of a construction project. Other important parts of a construction crane that are often found near the gear and motor are the working arm and operator cab.

The Jib

If you are looking for construction cranes near me, you may want to be on the lookout for a crane job. Beyond the mast, the jib is easily one of the more recognizable parts of a crane. The working arm is horizontal and long.

Attached to the jib is a trolly that helps carry the load. The machinery arm fits inside the jib and is always shorter. Within the jib are motors.

On the side of the jib opposite of the load are counterweights. The large concrete slabs help balance the load.

The Crane Operator

The laws of physics do not allow tower cranes to extend their heavy loads to the far end of the jib. Crane operators must keep a careful watch over the process to ensure that loads are moved carefully and safely.

The operators manage several factors at once from within the operator box that is usually located near the base of any crane. They have learned construction crane tips, and they use specialized hand signals to communicate with other members of the construction crew.

How Do Tower Cranes Work?

How Do Tower Cranes Work?

Modern urban landscapes would not be possible without the invention of the tower crane. Since 1949, when Hans Liebherr created the first tower crane, cities across the world have relied on the heavy lifting crane to make worksite projects quick, safe, and efficient.

In this tower cranes guide, we will explore the basics of how these important devices work. We’ll even answer a popular question: Why don’t the cranes fall down or tip over?

How Do Tower Cranes Work?

Tower cranes soar up to 265 feet into the air and can lift up to 20 tons. Regardless of their stature, tower cranes basically have the same three parts.

Keeping each tower crane from tipping over is a base that crews bold to the concrete below. Crews then connect the base to a mast or tower.

The slewing unit attaches to the base. The unit has a motor and ring gear. The gear allows the crane to rotate.

The working arm (jib) carries the load. A trolly runs along the long arm and moves the load. The operator uses counterweights to lift heavy loads up to where they need to be lifted.

Last but not least, the operating cab allows a trained professional to maneuver the massive crane in a delicate choreography.

How Are Tower Cranes Constructed?

Putting together a tower crane is hard work. First, construction project managers may need to explore a tower crane buying guide or search “tower cranes near me.”

Tower cranes keep from falling over because they are bolted to a large, concrete slab. This slab may need to be poured weeks before a tower crane can be set up.

A mobile crane helps move the sections. The crane then grows one mast at a time.

The crew attaches a top climber between the slewing unit and the upper end of the mast. A hydraulic ram then lifts the mast 20 feet at a time.

The process is slow work.

While all tower cranes consist of the same basic components, crane operators use specialized designs for certain types of projects. Luffing cranes, for example, can raise loads at an angle to reduce the slewing radius.

Derrick cranes fit on rooftops. They do not require tall masts. Traveling tower cranes move on rails that allow the cranes to move laterally.

Do I Need a Tower Crane?

If you are working on a project that requires lifting materials to very high heights then you will require a Hiab crane to complete your work.

Tower cranes can lift and set steel at every level of your project. They can be used to pour concrete or set panels in place. They also can help with the placement of electrical and mechanical systems.

What Is a Telescopic Crane?

What Is a Telescopic Crane?

Around 11 million containers move through the Port of Los Angeles each year, filled with goods from all over the world.

Moving those containers from ship to shore is the job of 82 cranes up and down the port. They’re a great example of a telescopic crane, one of the most versatile options when you need to move heavy loads around. The maneuverable and tough machine offers a lot of flexibility to cover many needs around a worksite.

So, just what are telescopic cranes? How do they differ from other types? Continue on through this telescopic cranes guide to learn more.

About the Telescopic Crane

What makes a telescopic crane different from other types is the boom made up of many tubes fitted inside each other. This allows the boom to extend and retract using a hydraulic system. This allows for more flexibility in reaching loads and higher lifting capacities.

The flexibility of these cranes extends to height as well. These have the highest reach of any cranes and the height can be adjusted. That allows them to lift higher than other cranes as well.

Versions with a jib on top can also work as a tower crane. Overall, setup is quick, making a telescopic crane ideal for emergency or rescue jobs.

Telescopic Crane Types

Telescopic cranes come in a few different categories. While they’re usually not mobile, some called crawlers can be. The crawler style can cover different and uneven surfaces to allow it to move to where it’s needed.

Other ways these cranes are categorized is through specific equipment or feature setups. These include capacity, number of units, and number of engines.

Smaller capacity telescopic cranes use slewing cylinders, while larger models use slewing rings. A single unit crane can easily be moved from one place to another, while a double unit has two parts — a mast and a jib — that make it more stationary.

A single-engine crane has just one engine powering the undercarriage and superstructure of the crane. A separate-engine version has a larger carrying capacity thanks to having two separate engines, one powering the undercarriage and one powering the superstructure.

Who Uses Telescopic Cranes

These cranes are part of many day-to-day hauling operations. With 80 to 90 percent of the world’s goods moving through ports, they find a lot of use there moving heavy loads around deck or from ship to shore.

Telescopic cranes are also common for building oil platforms offshore and in rescue operations like to raise salvage sunken ships. On worksites, their large carrying capacity makes them perfect for moving materials and equipment around.

Need a Telescopic Crane?

A crane can help you get more done, especially one with the flexibility a telescopic crane offers. You might consider different types of cranes, but if you need one that gives you plenty of height and the ability to handle the heaviest loads, a telescoping version is the one for you. This style is ideal for use in lots of industries, from shipping ports to construction sites.

Mobile Cranes vs. Tower Cranes: What Are the Differences?

Mobile Cranes vs. Tower Cranes: What Are the Differences?

Urbanization and industrialization have led to a boom in the crane industry. Most metropolitan areas sport skylines dotted with construction cranes. These sophisticated machines increase efficiency at any job site.

When it comes down to choosing what type of crane is needed, the choice often boils down to either a mobile crane or a fixed tower. According to the Rider Levett Bucknall Crane Index, tower cranes make up 69 percent of the overall number of cranes at residential and mixed-use projects.

There are significant differences between mobile cranes and tower cranes, though. Here’s a look at what separates these machines.

What Are Mobile Cranes?

Mobile cranes are integral to modern construction work. These machines get their name from their ability to move about a job site. This versatility often affords site managers the necessary flexibility to finish their work.

Mobile cranes come in a variety of designs and styles. Most feature either a cable-controlled or hydraulic-powered telescoping boom. They’ll come fitted with outriggers, which are legs that extend out for stability, that increase the crane’s working radius.

A crawler crane comes set on tracks for mobility. A knuckle boom crane provides precise maneuverability, fast loading, and compact storage. And there are many others.

What Are Tower Cranes?

As the name would suggest, they reach high into the sky and remain a common fixture at most construction projects. Tower cranes stand among the most popular fixed crane options in construction. They’re built as a vertical metallic structure, with a horizontal boom capable of rotating.

Tower cranes are particularly useful for moving concrete, large tools, steel, and other building materials at select job sites. These machines are fixed to the ground, which robs them of any mobility but affords greater stability for load-lifting.

Tower cranes come in various sizes and types, with operating attributes dictated by the types of mounting and jib, among other elements. Some of the specific types of tower cranes include articulated jibs, rail-mounted, and self-erecting.

Mobile Cranes vs Tower Cranes

To decide which type of crane you’ll need, you must evaluate the project at hand. Project specifications will dictate the equipment, and budget will play a role as well.

Mobile cranes come with. a fast setup time, allowing the work to commence sooner. Tower cranes must be assembled on-site, which takes time. Mobile cranes also take up far less space than tower cranes.

Mobile cranes feature durability, flexibility, and mobility. They tend to be the more cost-efficient investment for most construction projects. Tower cranes, on the other hand, provide greater height and reach, and come with strong load-lifting capacity.

You’re better able to handle your work when you invest in equipment as useful as bucket cranes. These crane systems are useful in a number of ways.

The tips in this article will help you out when you’re interested in buying a bucket crane.

What Exactly is a Bucket Crane and What Does It Do?

Before you set out to buy a crane, it’s important that you understand what kind of work they can do for you.

These cranes feature jaws-like buckets at the top that grab and scoop materials. The bucket attachment is suspended by a lever that can move in different directions to collect and lift items with precision.

Many companies invest in crane bucket equipment that will help them with several different projects — such as road construction, work in ports, repairing and building bridges, utility line maintenance, and more.

What Are the Benefits of Bucket Cranes?

There are numerous benefits to using bucket cranes.

For one, these projects reduce fuel consumption and CO 2 emissions, which makes for a cleaner project. Expect eco-friendly and sustainable construction to remain a trending part of the industry for the next several years.

A crane truck with bucket will handle a large amount of work that may otherwise involve an entire crew. This cuts down on time expenditures and helps to lower the overall cost of the project.

Cutting time and costs in this manner gives you a better return on investment (ROI) and allows you to hit schedules and objects.

You’ll also reduce the risk of injury with bucket cranes, as they contribute to a safer work environment.

What Types of Bucket Cranes Are Available?

Take the time to study the different types of bucket cranes on the market.

Perhaps you need a clamshell bucket crane or a concrete bucket for crane use. Other types include four rope grab, single and double-rope grab, scissor grab, electric motor grab, and multiple valve grab buckets.

You can buy a man bucket for crane use and employ your own professionals, or outsource the work to a crane operator.

Make certain that any crane operator you use is licensed and trained under Occupational Safety and Health Administration (OSHA) protocols and guidelines. This is critical since there are nearly 300 crane deaths per year on worksites all over the United States.

Invest in a Bucket Crane That Will Serve You

A bucket crane can serve you in a number of ways. When you understand both the benefits and uses, it’s easier for you to take control of your construction projects.
