Construction Crane – In fact, you will often find these objects or equipment in construction areas. You should know that a crane is one of the heavy equipment that is generally used to help lift something heavy. Well, for more details, let’s take a look at the crane reviews ranging from understanding to types.
What is a crane?
The crane is one of the lifting and moving materials. Generally, this heavy equipment is used to move an item in large quantities.
This equipment has a long shape and the ability to lift is very strong. Capable of rotating up to 360 degrees with a range of up to tens of meters. Usually this equipment is often used in projects, workshops, industry, ports, warehousing and many others.
Pulleys or cranes are machines that generally operate with oil or hydraulic systems and of course with the help of pneumatic or air systems.
This equipment lifts the load vertically and horizontally to lower the load to a place that has been determined by the mechanism. Therefore, there are several types of cranes to suit your working methods.
1. Tower crane
Tower Crane is a type of crane that is commonly used in building construction projects. In the construction of a high-rise building, this heavy equipment is necessary to facilitate the development process.
The height of the tower crane is 70-80 meters and it is equipped with a heavy material lifting capacity of up to more than 20 tons.
Having a large shape, installing a tower crane is time consuming. The setup for using a tower crane is to stay where the crane is plugged in.
The base of this tower is made of concrete and large, high-quality bolts are used for the fixing process.
2. Truck crane
For the next type, i.e. truck crane or mobile crane. This type is on top of a truck and has the flexibility to move towards the merchandise to be transported. Of course, it is different from the tower crane which is just plugged in.
The crane truck can be brought directly to the construction project site without the use of a transport vehicle. Despite being on top of a truck, this crane can function like any other type and can rotate 360 degrees.
3. Hydraulic crane
Hydraulic crane is a type of crane that can only be used on a workshop or warehouse scale. For this type, it has a fairly simple structure but is not flexible to move from one point to another. In terms of its reach itself it is also limited, hydraulic cranes do not have a great reach and can only rotate up to 180 degrees.
4. Crawler crane
In addition, there is a crawler crane, this equipment is included in one of the construction equipment that is capable of carrying heavy goods and has a transport range.
The crawler crane is a type of crane widely used in construction projects with a not so long reach. The wheels are equipped with chains that allow the crane to move when used on various terrains.
5. Lifting crane
In fact, a crane is a machine that does not always work on land, but can be mounted on a roof like this lifting crane. This equipment is often used in workshops and warehouses. This crane hoist has special components on the right and left. The existing rails are useful as a path for the hoist to move back and forth horizontally.
6. Railway cranes
This type of crane is often used to transport materials for the construction or repair of railway lines. In addition, this railway crane is equipped with special tires that can make it work on the train tracks. These tires usually have a name which is wheel flanges. In fact, this type of crane is very rare, right?
7. Floating crane
In general, a crane is a machine that can not only be used on the ground or installed on the ceiling. However, this equipment can also operate over the ocean. It is used to assist in bridge or port construction projects. This type of crane has an advantage, namely, it has a large transport capacity of up to more than 9000 tons. This crane can even lift a sunken ship under the sea.
8. Telescopic handler crane
Telescopic cranes are often used for projects on coal, to install steel frames on top, and many other functions. This type of crane has a part made of forklift at the tip of the pump. In addition, it also has an outcast at the base. Of course, this crane can rotate up to 360 degrees.
9. Port crane
The next type is the port crane. By the name, of course, you can already think that this equipment should be used as equipment in the port. Yes, that’s right, generally this equipment is used to load and unload ships that have just arrived at the port.
10. Air crane
Hearing just the name must have made you imagine that this type of crane is moving through the air. The idea is certainly true, this equipment has a name, namely an overhead crane. It has a shape similar to a helicopter and is generally used to hit targets that are difficult to reach. Equipped with a cable, this is the one used to hang the load you are carrying.
11. Luffing crane level
The leveling crane is a type of crane that is generally found in the port area. This crane has a hinged bracket that will move up and down. This up and down movement causes the crane arm to move in and out. It is often used to place containers or unload cargo on ships.
12. Floating crane
Floating cranes are necessary equipment for the construction of bridges or ports. Not only that, this equipment is also used for loading and unloading ships. With a large capacity of up to 9000 tons, this equipment can also be used to lift boats submerged in water.
Criteria for choosing a crane
In terms of selection, a crane is a device to move or divert material based on a field site that is not wide. Having several types of cranes means that you have to consider in advance what the project conditions are, the format of the building structure, and the operating facilities both during installation and during dismantling.
While the selection of crane capacity can be seen in several things, including:
- Mounting the device in the project environment
- equipment lift
- The weight of the equipment components supported by the base frame.
- The space in the equipment
- The area of the location that the equipment should reach
- Device speed for diverting material
That’s a look at the crane starting from a brief explanation, the types and their functions and the latest criteria in the selection of cranes. It is not interesting if we know, it turns out that there are many types of cranes that operate according to your needs in the transport of heavy goods.
Hopefully the discussion about what a crane is, its types and functions can contribute to its understanding.
