Koh Kock Leong Enterprise Pte Ltd has one of the largest selections of excavators for rent in Singapore. Excavators are considered one of the essential equipment in construction and earthworks. They are mainly used for digging and moving loose materials. However, they can be used for other purposes such as hammering, grappling, thumbing, pulverizing, drilling, sawing, flail mowing, and ripping with the proper attachment and configurations.
There are various types of excavators, and they can come in different sizes.
Excavators can generally be categorized into five types:
The most common type of excavator and is mainly used for mining, landscape grading, and trench digging. They are called a crawler excavator because it runs on two rotating tracks instead of wheels. Crawler excavators are the ideal type of excavator for steep, rough, and muddy terrains.
As the name suggests, this excavator runs on wheels instead of tracks. Wheeled excavators can be used for digging, demolition work, moving barriers, cleaning ditches, mowing, cutting asphalt, and grinding tress like crawler excavators. Although they are fast, Wheeled excavators are only operable on hard and flat surfaces.
These are crawler excavators with lengthy arms and boom. The arms are extendable from 40 to 100 feet which is ideal for jobs that are only accessible from a distance. They are commonly used for demolition projects over a lake or river.
The drag-line excavator is larger than the standard excavator. It also operates differently. Instead of using hydraulics, it uses a hoist rope system and a dragline to raise or lower the bucket or attachment. Drag-line excavators are commonly used for deep pile driving, harbor construction, surface mining, deep excavation, and underwater operations. They can reach depths of up to 213 feet or more.
When it comes to sizes, excavators can be classified into 4 classes:
These are the smallest of the four classes. Mini excavators generally weigh less than 6 tons and are ideal for small spaces and indoor works. They are commonly used for projects that do not require the size and power of larger machines.
Midi excavators generally weigh between 6 to 10 tons. They offer more power compared to mini excavators in small spaces. Midis can also be used for more standard projects like construction and earthworks. They have excellent maneuverability thanks to its size.
Standard excavators generally weigh between 10 to 45 tons. They are the most popular class of excavators and are commonly used in commercial construction. Standard excavators not only offer more power and reach compared to the mini and midi class, but their hydraulic systems enable them to handle multiple tool attachments.
Large excavators are the largest among the classes and weigh more 45 tons and above. They are necessary for massive construction and demolition works and require oversized trucks to transport them to and from the worksite.
