Dragline

Definition

A bucket attachment for a crane, commonly used in marsh or marine areas, that digs soft materials from a distance and draws the bucket towards the crane using a cable.

Purpose

Draglines are used for excavation in environments where conventional digging methods are impractical. They allow for the removal of materials from a distance, making them ideal for working in wetlands, riverbanks, and other challenging terrains.

Examples of Use

1. Wetland Excavation: Removing soil and debris in marshy areas for construction or environmental management.
2. River Dredging: Clearing sediments and debris from riverbeds to maintain navigation channels.
3. Mining Operations: Used in surface mining to remove overburden and expose mineral deposits.

Related Terms

• Excavator: A machine used for digging and moving large amounts of earth.
• Crane: A machine used for lifting and moving heavy objects.
• Bucket: An attachment for heavy machinery used for digging and moving materials.

Notes

• Draglines are typically used for large-scale excavation projects due to their size and reach.
• Proper operation requires skilled personnel to ensure safety and efficiency.
