Dragline excavator is a heavy equipment that is often operated in construction activities, mining, and infrastructure development. Has a long pole component (boom) with bucket, dragline excavator used for the work of digging and transporting materials in various fields.
This heavy equipment is needed in construction work for the excavation of trenches and holes, the installation of a spiking pole, until the demolition of the structure. Use dragline excavator also plays an important role in the mining industry to explore the material, to load the material to the truck or conveyor.
Dragline very reliable in large projects because it offers advantages to be able to transport large amounts, Digging thick material, and others. Considering its use is very crucial, Let's recognize what functions dragline excavator, the types, as well as the way he works.
What's that Dragline Excavator?
Dragline excavator is a heavy equipment used for the excavation and transfer of materials in large -scale construction projects and mining activities. Different from type excavator general, This tool has a frame component boom the long as well as hoist and drag cable to direct bucket.
Dragline excavator designed with the ability to work efficiently in areas that are difficult to reach. This tool is able to explore material in large quantities at a certain depth or a large area. Dragline has a longer range than shovel, so that it can operate without having to enter the excavation area.
Usage dragline can accelerate and increase the efficiency of excavation tasks and move material to the transportation, like a truck or to the point of hoarding. Besides that, there are several types dragline with special functions that can be tailored to work needs.
Function Dragline Excavator
Main function dragline excavator is to explore and move material efficiently. But besides that, This heavy equipment also has other uses in supporting activities in construction and mining projects.
Here are some functions or uses dragline excavator that you need to know:
- Perform land excavation
- Move the material to the transport truck or conveyor
- Installing piles in construction projects
- Digging under water, like in the lake, pool, channel
- Dig a ditch, tunnel, and hole
- Dismantle the building or the old structure
- Helping land reclamation to restore degraded areas
Types Dragline Excavator
This heavy equipment consists of several types by working and different specific functions. Use of type dragline can be adjusted to the work needs, be it from the type of material, dug power or transport, until the location of the field of work.
Here are some types dragline excavator that you need to know their own uses:
1. Hydraulic Dragline Excavator
Type dragline This uses a hydraulic motorbike as a driving machine. Drive component it is installed on boom and operated by the operator through the control lever. This technology is ideal for the work of exploring materials with a lighter burden.
2. Electric Dragline Excavator
Dragline This type uses more efficient electric -based technology compared to hydraulic motors. Electric dragline excavator does not require liquid for operation, but rather utilizes electricity that provides a strong appeal.
However dragline This type requires a stable and reliable power source to operate optimally. If you want energy efficiency and performance, dragline Electricity is suitable for you to use.
3. Crawler Mounted Dragline
Dragline This is designed to be used on soil or surface with low carrying capacity, so it tends to have a level floating its tall. But compared to other types, This tool has a relatively slow operating speed and requires additional transport vehicles to move them to the work location.
4. Wheel Mounted Dragline
Wheel mounted is the type dragline which offers optimal performance in almost all excavation locations. This tool is often used in areas with moist soil conditions but not flooded, Thanks to the tire compound which allows fast movements.
Besides that, dragline It has a fairly high mobility capability with speeds up to 30 mph. This makes it easier for this heavy equipment to extract material in various fields.
How Dragline Excavator works
Dragline operation starts from managing its position in accordance with the targeted task. The operator will regulate and move its components to do work safely and optimally. To better understand it, The following is how the Dragline Excavator works:
- Posisi Dragline
Dragline excavator generally positioned in a higher area or parallel to the material to be excavated. This placement is possible bucket move efficiently to dig, transport, and moving materials.
The excavation process begins by swinging the empty bucket to the excavation point. At the same time, drag cable and hoist cable must be loosened, so that bucket will fall in a perpendicular position downward.
- Excavation process
The excavation process begins by lowering the bucket using a cable dragline towards the material to be explored. After that, bucket pulled with the main cable to drag the material, which allows the material to enter inside bucket.
By attracting drag cable and move hoist cable, bucket can be tailored to follow the surface of the cliff to be dug. The eradicated material or layer will accumulate and enter bucket.
During excavation, hoist cable usually will be locked. When the cable is pulled back, Bucket starts moving to form a circle, with the center of the circle at the end of the boom at the top.
- Material removal
After bucket fully charged, The lift cable is used to lift bucket from the excavation area. Then bucket transferred to the destination location, such as transport trucks or storage areas, by turning boom dragline towards that location.
- Material Transportation
Material transfer is done by opening the bottom bucket Using the release mechanism. Material inside bucket will fall to the destination because of gravity, so the process becomes faster and more efficient. After that, dragline back to its original position to start the next excavation.

The advantages and disadvantages Dragline Excavator
Although offering a number of advantages to handling project work, dragline also has some deficiencies. Here are the advantages and disadvantages of heavy tools dragline excavator that you need to know:
Advantage
- Efficiency for excavation and transportation in large quantities
- Can be operated in various difficult conditions or terrain
- Able to extend land and materials with extra thickness
- Has a distance range with a light and long boom
- The ability to work in areas that are difficult to reach
- Has flexibility for the use of various projects
Deficit
- Fairly high operational costs
- Have limitations for jobs on certain types of soil
- Need equipment and other tools to move
- Need a wide work area
- Requires a skilled operator to operate it
- Mobility is not as fast as the type of hydraulic excavator
The importance of using Dragline Excavator which is right for construction and mining projects
Usage dragline excavator plays an important role in efficiency to excavate, transportation, as well as other tasks in large scale and mining construction projects. Type operation dragline must be adapted to the needs of the job. Also make sure to choose dragline the quality and the condition is prime.
