1. What is the overall function of your Application of Engineering?

114202285391 — 2024-01-11 12:34:29 UTC

Diggers are used for digging trenches and breaking holes to lifting away waste and excavating mines.

2. Who was the inventor / developer of this application of engineering?

114202285391 — 2024-01-11 12:35:56 UTC

The very first excavation machine was built in 1882, by. Sir W. G. Armstrong's company in England and it was. used for digging the plot for the docks in Hull

3. What are it's main parts and features?

114202285391 — 2024-01-11 12:37:24 UTC

The main parts are,bucket,boom,engine,arm,tracks,cab and swing drive.

4. What features make the application of engineering safe for it's operators and the people around it?

114202285391 — 2024-01-11 12:38:29 UTC

Size, Weight and Tail Swing. First and foremost, you'll need to consider what size and weight you need in a mini excavator. ...
Safety Seatbelts. Seatbelts are critical when operating any heavy machinery. ...
Cab Comfort. ...
Travel Alarms. ...
Camera and Monitor Systems.

5. How is your application of engineering structured?What geometric shapes are involved?

114202285391 — 2024-01-11 12:39:44 UTC

Whatever you choose to call them, there are three key sections to an excavator. Some call this the undercarriage, house and boom and others use terms like attachment, base frame and undercarriage or boom, upper structure and lower structure.

6. Think about the forces acting upon your application of engineering. Are there different types of strengths?

114202285391 — 2024-01-11 12:40:52 UTC

7. What materials are used for it's main parts? Why have these materials been selected? Define the properties of the materials used

114202285391 — 2024-01-11 12:41:49 UTC

The booms and arms of backhoes and excavators, since they need considerable tensile strength, are often made of low-alloy steels that have been heat-treated to get the needed tensile strength—50,000-100,000 psi—and toughness levels

8. What are the different types of movement? What is a mechanism?

114202285391 — 2024-01-11 12:43:08 UTC

There are a few different mechanisms that are used in an excavator . The three most common are an impact hammer, a rotating impact hammer, and a hydraulic cylinder. Impact hammers are commonly used for non-metallic (soft) materials. They are typically much less expensive than a hydraulic cylinder

9. What type of movement or motion does the engineering application take? Do these movements have to be accurate and precise? How does it achieve the required motion?

114202285391 — 2024-01-11 12:48:20 UTC

Excavators typically use hydraulic systems to operate. These hydraulic systems consist of a hydraulic pump, control valves, hydraulic cylinders, and hydraulic motors

10. What manufacturing processes are involved in the making of the engineering application? Describe one of these processes in detail

114202285391 — 2024-01-11 12:48:45 UTC

This detailed description of the invention adopts following manufacturing process: 1, select structural alloy steel, different size bucket tooth is selected different size steel, band sawing machine fracture; 2, intermediate frequency heating to 1100 DEG C; 3, steel head reserves 30MM, T-shaped by 400KG pneumatic

11. How are the main components joined together? Can they be disassembled easily?

114202285391 — 2024-01-11 12:49:12 UTC

There are typically three types of cylinders on an excavator: boom, arm and bucket. The cylinders connect between each section and are responsible for articulating each. For example, the bucket cylinder connects between the arm and the bucket, and helps move the bucket back and forth.

12. Does your application of engineering involve an electronic circuit? What basic electronic components are in place? What is the function of each component you listed?

114202285391 — 2024-01-11 12:51:22 UTC

The controller has a backup system for operator dry operation. When there is a problem with the electronic control system, the operator can activate the backup system to control the size of the main spring and the engine throttle. The backup system consists of a backup device for the governor that controls the engine speed and a backup device for the main pump. When there is a problem with the electronic control system that controls the governor, the operator can activate the governor backup device, and when there is a problem with the electronic control system that controls the main pump, the operator can activate the main pump backup device.

13. How is your engineering application maintained? Could it fail, deteriorate or corrode? What keeps it's parts running smoothly?

114202285391 — 2024-01-11 12:51:54 UTC

Maintain and clean your undercarriage. Working in dirty, muddy terrains can cause undercarriage buildup. ...
Check your tracks. Check to see that your tracks have the right tension. ...
Change out your air and fuel filters. ...
Monitor fluid levels. ...
Drain water separator.

14. How does your application of engineering impact the environment? Has there been any improvements made to help reduce it's environmental impact in recent years?

114202285391 — 2024-01-11 12:52:15 UTC

The act of digging and moving soil releases dust particles and machine emissions into the air. Not only does this reduce air quality, but prolonged exposure can have health implications

15. Can you describe a local, national or global company that produces your chosen application of engineering? What would the cost be?

114202285391 — 2024-01-11 12:52:36 UTC

Hitachi is my favourite company,they are 1hr drive away from my home.They are one of the most popular digger brands.They cost between £200,000 to £600,000.
