Question

What of the following machines can be used for the top-soil removal?
1. Jackhammer drill
2. Scraper
3. Shuttle car
4. Shredder

Answer 1

Correct Answer - Option 2 : Scraper

Concept:

Jackhammer drill:

• A Jackhammer drill is a pneumatic or electro-mechanical tool that combines a hammer directly with a chisel.
• Jackhammers are used to demolish old concrete, remove pavement, and demolish many other surfaces in projects.
• The jackhammer itself is heavy, so, only appropriate personnel should handle the tools to reduce the risk of accidents.

Scraper:

• It is a machine for moving earth over short distances (up to about two miles) over relatively smooth areas.
• Either self-propelled or towed, it consists of a wagon with a gate having a bladed bottom.
• The blade scrapes up the earth as the wagon pushes forward and forces the excavated material into the wagon.

Shuttle car:

• A vehicle on rubber tires or continuous treads to transfer raw materials, such as coal and ore, from loading machines in trackless areas of a mine to the main transportation system.

Shredder:

• A shredder is a machine or equipment used for shredding. Shredding systems are used to reduce the size of a given material.
• The shredding process produces raw material to be re-introduced into manufacturing.
