Crawler excavators
For intensive excavation work on unstable surfaces, crawler excavators are the answer. A crawler excavator is an excavator that remains extremely stable in a variety of conditions thanks to its tracks. This machine has no problem with difficult to reach places, uneven surfaces or swampy environments. Caterpillar excavators not only easily drive over bumps and potholes, but also level the ground at the same time. During excavation work, the machine scoops the soil towards the cab, which provides additional stability and prevents the machine from tipping over.
Specifications of crawler excavators
Weight capacity
Crawler excavators come in all shapes and sizes. They start at a weight capacity of 1 tonne, but can be as heavy as 90 tonnes. The compact 1 or 2.5 tonne models, also known as mini crawler excavators, are functional and accessible for many companies with different purposes.For example, they can be transported with a trailer, which means that the carrier does not need a large driving licence.The large machines are suitable for heavy earthmoving work and must be transported professionally.
Crawler
The tracks, which are also called tracks, come in different widths. For heavy excavation work on unstable ground, a tracked excavator with a large weight capacity and wide tracks is necessary
Accessories
With many tracked excavators, it is possible to connect different attachments to the excavator arm. These attachments are easy to change by means of a quick coupling. This allows different jobs to be carried out with the same excavator. Telescopic excavators also have an extendable arm, which makes them suitable for loading freight.
Demolition excavator
Is the machine used exclusively for demolition? Then we also speak of a demolition excavator. These demolition excavators are fully configured to make demolition work as easy as possible.They have a special cab, straight boom and different attachments to facilitate demolition work at different heights.
Crawler excavator work
Due to its stability, the crawler excavator is particularly suitable for heavy earthmoving work on rough terrain. The machine is often used in road construction, demolition work or in the agricultural sector.Gardening companies also use mini tracked excavators.Finally, loading and unloading of lorries or ships is regularly done with telescopic excavators.
However, the tracks make it difficult for a crawler excavator to drive on ordinary roads. The tracks cause a lot of friction with the road surface, so the machine moves slowly and can also cause damage to the asphalt. Caterpillar excavators are therefore not suitable for travelling longer distances.They are often transported or moved with a trailer.For greater mobility, a wheeled excavator on pneumatic tyres is more suitable.
Unlike a wheel loader, excavators do not have a large load back. Therefore, although they can excavate quickly and effectively, they cannot move large amounts of material at the same time.Due to its limited mobility, the tracked excavator operates most efficiently when working in one place as much as possible, or when travelling short distances.
