Mini Excavator

Mini excavators are compact machines that are easy to operate and maneuver. These machines are suitable for projects that require a machine with a small footprint.

The center ground clearance of a mini excavator ranges from 1 to 2 feet, while the ground clearance is about 6 inches. The height over the cab can range from 7 to 8 feet, while the track length ranges from 6 to 8 feet.

The counterweight clearance can be up to 2 feet, and the length of the machine can be up to 12 feet. The swing radius can range from 6 to 8 feet, and the track shoe width is typically 12 inches.

Dimensions of Excavator Buckets

General Purpose Bucket Dimensions

General purpose buckets are designed for digging and material handling. These buckets have a flat bottom and a curved surface that helps to scoop up materials easily.

The width of a general purpose bucket ranges from 12 to 48 inches, while the depth ranges from 12 to 36 inches. The height of a general purpose bucket can range from 20 to 48 inches.

Grading Buckets Dimensions

Grading buckets are designed for smoothing and leveling surfaces. They have a flat bottom and a wide opening that makes it easy to level surfaces.

The width of a grading bucket ranges from 60 to 96 inches, while the depth ranges from 36 to 48 inches. The height of a grading bucket can range from 18 to 24 inches.

Tilting Bucket Dimensions

Tilting buckets are designed for digging slopes or ditches. They are equipped with a mechanism that allows the bucket to tilt while digging, which makes it easier to create sloping walls.

The width of a tilting bucket ranges from 24 to 72 inches, while the depth ranges from 24 to 36 inches. The height of a tilting bucket can range from 24 to 36 inches.

Conclusion

Excavators are versatile machines that are designed to carry out a range of tasks. From general-purpose excavation to leveling and grading, there are excavators for various projects.

Understanding the dimensions of different excavators and their buckets is crucial for choosing the right machine for a given project. We hope this article has given readers a clear idea of the dimensions of excavators and their buckets, which will help them make informed decisions when selecting machinery for their projects.

Dimensions of Excavator Boom

Excavator booms are the long arms of the machine that are used for digging and moving materials. The dimensions of the boom can make a significant difference in the performance and versatility of the excavator.

There are different types of excavator booms, each with specific dimensions that are suited to various projects.

Standard or Mono Boom

The standard or mono boom is the most common type of excavator boom. It consists of one long arm that is attached to the excavator’s cab.

The length of the boom can range from 10 to 40 feet, depending on the size of the excavator. The stick, also known as the dipper, is attached to the end of the boom and can vary in length from 4 to 10 feet.

The combination of the boom and the stick determines the digging depth and reach of the excavator.

Two-Piece Boom

The two-piece boom is a more specialized type of excavator boom that is used in projects that require greater reach and digging depth. The two-piece boom consists of two arms that are connected by a hinge.

The length of the boom can range from 40 to 100 feet, depending on the size of the excavator. The hinge allows the operator to adjust the angle of the boom, which makes it easier to dig holes at different angles.

Long-Reach Boom

The long-reach boom is a specialized type of boom that is used in projects that require a machine with an extended digging capability. The long-reach boom has a longer reach than the standard boom, which makes it ideal for projects that require excavation around waterways or bridges.

The length of the long-reach boom can range from 40 to 100 feet, depending on the size of the excavator.
