Types, usage, and concepts of the dragline excavator

The dragline is a type of heavy machinery. The dragline excavator is used in civil engineering and surface mining projects. The dragline is the world’s largest piece of machinery ever manufactured. It has the potential to dig quite deep into the ground. The term “drag” is used because it can drag material from a long distance away from the machine. Draglines are made up of a drag rope, a big bucket, a boom, a hoist rope, and drive motors.

A dragline boom is linked to a huge bucket (it is a truss-like structure). A multitude of ropes and chains are used to control the bucket. A bucket is tied to two different function ropes.

These are;

1. Hoist rope
2. Drag rope

An electric motor controls the hoist rope, which supports the hoist-coupler system and the bucket from the boom. The drag rope, on the other hand, is used to pull the bucket horizontally towards the machine

USES OF DRAGLINE

Dragline is used for;

1. excavation of a road
2. Driving piles deep into the ground
3. Ports, harbors, and other structures are being built.
4. Mining on the surface
5. Excavation to the depths
6. excavation of the subsurface

TYPES OF DRAGLINE

There are three types of dragline;

1. Wheel-mounted dragline
2. Crawler type dragline
3. Truck-mounted dragline/portable dragline.

Dragline places the bucket on top of the source and drags it horizontally. As it got near to the machine, the bucket began to tilt.
