Excavators

Excavators play different roles in industries ranging from construction to mining to forestry to demolition and then some. Originally designed as diggers, excavators can now lift heavy weights as well as demolish structures. As a result, what you want an excavator to do plays a crucial role in the model you should select.

Work Conditions

No matter what kind of heavy machinery you buy, the first thing you need consider is the space you’re working with. For instance, while some excavators are ideal for broad landscapes, they might not serve the purpose in narrow urban spaces. How deep you’ll need the excavator to dig is another aspect that needs your attention. Establish if you’ll need to move the excavator between locations and if it’ll need to travel through weight-limited roads and bridges. Don’t forget about its storage when not in use.

Size Matters

An excavator’s digging power and depth mainly depends on its size. Micro and compact excavators weight up to 6 metric tons. Mini excavators typically weigh in between 6 and 25 metric tons. Standard sized models weigh from 25 to 40 metric tons and large models can weigh up to 90 metric tons.

Attachments

Other than the standard excavator bucket, you might need different attachments such as augers, thumbs, rakes, rippers, and hydraulic hammers. You may also need specialised buckets depending on the task at hand. For example, you’ll find special buckets for removal of pavements and heavy-duty buckets work best when lifting rocks. If the job involves separating rock and fine debris, a sorting bucket is what you’ll need.

Other Specifications

Bucket capacity is usually expressed in cubic centimetres (cu cm) and tells you how much volume the bucket can hold. Examine the excavator’s coupler options as this plays an important role in the attachments you can use with the machine. Altitude capability requires your attention if you plan to use the excavator at high altitudes. While most excavators come with steel tracks propelled by rollers, some come with wheels. The former offer greater stability and the latter provide increased mobility.
