What Is a Crane?
A crane is a machine that is used to lift and move heavy loads, machines, materials, and goods for a variety of purposes. They are used in all different sectors of industry, from construction to manufacturing to shipbuilding and material loading. Cranes are common along skylines as they are necessary to build the skyscrapers we so often see in our cities today.
The Basic Components of the Crane
While there are many different types of cranes, there are a few basic components worth mentioning. The main parts that can be found on a crane are the:
- Rotex Gear
- Reinforced-steel cable
The boom is the most recognizable part of a crane. The boom is a long arm that can either be telescopic or fixed. They take on a variety of roles depending on the type of crane and how it is built. They are able to work without jibs and are sometimes the main component on a crane.
The primary purpose of the boom is to lift, move and position material. They bear the majority of the load and are responsible for determining the reach of the crane.
Popular Types of Cranes
While there are so many different weight capacities, types, and functions for cranes, there are a few common ones seen in the construction industry.
The name speaks for itself! Mobile cranes are one of the most basic types to see in construction. Fitted with a steel truss or telescopic boom mounted to a platform, this type of crane can be moved to, from and around a site as needed. The platform in question could be wheeled, on a rail, or even fitted to a truck if needed.
Mobile cranes are often used for general construction and roofing. They are powerful enough to move materials and equipment while being less permanent than a tower crane.
A Tower Crane
When most people think of cranes this is what they think of. A form of balance crane, tower cranes are fitted into the ground and used to move and carry heavy materials for longer distances. They are most often used when constructing tall buildings.
A Lifting Machine
Cranes have been working alongside humans for over 2,500 years to build cities and neighborhoods. The ability to lift heavy materials and equipment has allowed us to build buildings that reach the skies.
The next time you see a crane or work alongside one, take a moment to appreciate the history behind it and the unique connection that this machine gives us to builders of the past.
Mobile cranes are mounted on crawlers or tires and offer greater mobility than standard cranes. Some mobile cranes are even able to be driven on the highway. Their ability to navigate around job sites and carry large amounts of weight makes mobile cranes a very popular addition to many projects.
Types of Mobile Cranes
Mobile cranes consist of an outstretched boom—often referred to as a lattice or telescopic boom—mounted to a truck or other mobile structure that travels via treads or tires. The boom can rotate up to 360 degrees and extend to varying lengths depending on the type and size of the crane. These types of cranes are not restricted to a fixed path and can move throughout a construction site and/or between sites.
A mobile crane is a very simple cable-controlled machine with a telescopic boom attached to its platform. It comes in different shapes and sizes and can be classified into different types. There are more than a dozen types of these cranes. Some of them are listed below:
- All Terrain
- Telescopic Handler
There are many lifting operations, where using a tower crane is not practical. The operations such as statue lifting or indoor lifts, can’t be executed by the static tower cranes. Therefore, the best solution to such a construction problem is, Mobile Crane.
Mobile cranes are faster to set up. The biggest advantage of a mobile crane is the flexibility and ability to access in areas where static crane can’t reach. Mobile Crane doesn’t require a lot of space. Mobile crane is a cheaper option of the types of major types of crane, so it is a cost-efficient option.
A crane mounted on a Truck provides the mobility for these types of crane. It is basically a self-propelled loading and unloading machine which consists of rotating cantilever boom. It uses the same engine for the undercarriage and the crane.
Advantages of Truck-Mounted Crane
Following are the advantages of Truck-mounted Crane:
- It can travel on highways itself.
- Its features make it easy to move and less expensive.
- They can be rotated up to 180 degrees, sometimes the expensive ones can even rotate 360 degrees!
- They can be used for multiple purposes.
- It can be used for loading and unloading of motor Truck rolling stock.
- It is highly flexible.
- Truck-Mounted Cranes travel nearly at 65 km/h.
Disadvantages of Truck-Mounted Crane
The disadvantages are:
- It moves at a low-speed around sites but is needed to be transported on the sites.
- They are not usually used for longer hire periods.
Depending on the type of mobile crane, the crane may or may not be road legal. Some sources define a mobile crane as this, while others define any crane mounted to a mobile vehicle powered by an engine as a mobile crane. For the purposes of this article, the latter explanation is considered a mobile crane.
The terms truck crane, boom truck, and truck mounted crane (TMC), are used interchangeably. Truck cranes are a type of mobile crane made of a boom mounted to a truck bed and are, therefore, road legal. Truck cranes are smaller, less versatile, and used for lifting lighter loads (load capacity limit of about 45 tons).

If you are wondering about what type of crane to be used for your upcoming project, here, we present the pros and cons of the different types of cranes. Let’s discuss the advantages and disadvantages of the top 10 most commonly used types of cranes.
How Much It Costs To Rent a Crane
Cranes are the most effective way to move heavy loads in a variety of situations. Renting is the easiest way to get access to many different types of cranes on a daily, weekly or monthly basis without having to actually purchase one.
When renting a crane, it is possible to use a national online rental network or a local crane service. In some cases, an online network actually helps you find equipment with a local partner, which provides you both the convenience of searching online and also the ease of working with a nearby company.
Before renting a crane, read on to learn about the following:
- Prices for average crane rentals
- Factors that affect the rental cost
- Advantages of renting a crane instead of buying one
Crane Rental Prices
Crane rental costs vary based on many factors, so the only way to get an accurate price is to request a quote from a quality vendor. Because there are thousands of models of cranes with different features and specifications, there is no simple answer about how much it costs to rent a crane. Nonetheless, it helps to have some idea of rental costs. Generally speaking, small mobile cranes cost around AED 200 per day to rent and large operated cranes cost closer to AED 1,000 per day, while large tower cranes can cost around AED 15,000 to rent for a month.
Besides the rental cost, make sure you consider additional costs that may be involved:
- Delivery and assembly: Many cranes must be delivered to the job site, like crawler cranes, or even assembled, like tower cranes.
- Permits: Often, cranes require permits to operate, so check with your local jurisdiction to understand the costs and paperwork involved.
- Qualified personnel: All cranes require qualified operators, riggers and signal persons, which are necessary for safe lifting.
- Other fees: Disconnecting utility lines, preparing a lift plan, paying for overtime and other costs come along with renting a crane.
These fees, though, are only a part of the factors that go into determining a crane’s rental cost.
Factors That Affect Rental Cost
A number of factors go into the final rental cost for a crane, and understanding them will help you make a good decision for your particular needs.
These are the most important factors in determining the cost to rent a crane:
- Type of crane: Depending on the type of crane you rent, costs will range from hundreds to tens of thousands of dollars. Small carry-deck cranes will be inexpensive, whereas operated cranes or tower cranes will cost much more.
- Lifting capacity: The more that a crane can lift, the more expensive it will be. Some of the largest mobile cranes can lift more than 1,000 tons.
- Location: Depending on the country or state you’re renting in, prices can vary dramatically.
- Duration of rental: While it is always more expensive to rent a crane for a longer period of time, the cost per day drops dramatically when you rent a crane on a weekly or monthly basis.
- Current demand: During construction booms, cranes are in high demand, and costs can rise significantly.
Considering all of these factors will help you better understand what you’re looking at when you request a quote for a crane rental.
You may also want to consider whether it makes more sense to rent a crane or purchase one depending on your particular situation.
Advantages of Renting a Crane
Though purchasing a crane can be a good long-term investment for some companies, most people are better off renting a crane for a number of reasons.
and knuckle boom cranes, that decision can be even more difficult due to the similar work applications and capabilities of both. While there are many reasons to choose either type of crane, it often comes down to a customer’s personal preference and intended work applications. Both boom truck and knuckle boom cranes offer distinct advantages based on their intended use.
Which Type of Crane is Right for Me?
The first step in determining which type of crane to purchase is to consider where and how you intend to use it. These truck mounted cranes can be used for multiple work applications, such as electric line maintenance and construction for both transmission and distribution infrastructure, tree trimming and removal, material delivery, and general day-trade construction use. Additionally, it’s important to understand the basic structural differences of each type of crane.
To better help you choose which crane you need, we’ll cover work applications and basic features that apply to both pieces of equipment.
Knuckle Boom Cranes
A knuckle boom crane (also known as an articulating crane) is a piece of heavy equipment designed to lift loads, handle and deliver material and conduct work at the boom tip through a variety of attachments. These cranes are created to be lightweight and highly maneuverable for maximum payload while working in tight spaces.
Telescopic Boom Trucks
A boom truck crane, or a telescoping crane, uses high-boom angles and a hoist to lift loads. These cranes are designed for strength and stability and are typically used to lift heavy loads vertically.
Load placement, the weight of your load and your ability to transport it are all essential factors to consider when deciding which type of crane will best fit your daily work needs.
When it comes to load placement, a knuckle boom crane can be a good choice for moving loads point to point, whereas a boom truck crane is sometimes better at moving a load vertically or up and over obstacles such as structures or trees.
If you’re considering the size and weight of a load, heavier items that need to be moved farther away are best lifted by a boom truck crane. Larger loads that need to be moved to a jobsite are best carried by a knuckle boom crane because it doesn’t have the limitation of having a boom stow over the bed.
