Construction Equipment refers to heavy-duty vehicles, specially designed for executing construction tasks, most often ones involving earthwork operations.

Type of Construction Equipment

The following is a list of different heavy construction equipments,

1. Power Shovel

Types of Construction Equipment
Power Shovel
  • There are three types of power shovel, crawler-mounted, truck-mounted, wheel mounted.
  • It is used to excavate earth of all classes except rock and load it into the wagon.
  • It major parts mounting, cab, boom dipper stick and hoist line.
  • It is useful to excavate the soil at or above the operating level of the ground.

2. Drag Line

Types of Construction Equipment
Drag Line
  • Dragline type of excavator is used for digging at or below the operating level.
  • They are used to excavate soft earth.
  • The basic part of the dragline is the mounting, cab, boom, hoist cable, dump cable, bucket, drag cable, etc.

Dragline is useful under the following conditions:

 1. The bottom conditions are wet. i. e. dredging in river beds.

2. The ground to be excavated is soft medium-hard.

3. The digging is to be done well below the ground level.

4. The stuff is to be dumped as far from the unit as possible.


3. Clam Shell

Types of Construction Equipment
Clam Shell
  • It is used to excavate soft materials and loose materials at or below the existing ground surface.
  • It consists of a bucket of two halves which are hinged together at the top. The bucket is allowed to reach on the top of the loose material to be dug. As the bucket is lifted, the two halves close entrapping the material into the bucket.
  • It is also used for stockpiling.

4. Trenching Machine

Types of Construction Equipment
Trenching Machine
  • These machines excavate trenches of constant width with accuracy and speed. Width of trenches ranged from 250 to 450 mm, while depth up to 4m.
  • Trenches for mains, gas lines, oil pipes lines, telephone cables, drain ditches, sewers, etc. are dug with the help of a trenching machine.
  • These machines are generally crawler mounted. These machines can either wheel type or ladder types

5. Hoe

 Hoe - Construction Equipment
Hoe
  • It is used to excavate below the natural surface to keep precise control depth of excavation at close range work.
  • It can exert high tooth pressures and hence can excavate stiff material when normally cannot be excavated by dragline or power shovel.
  • A hoe is used to dig at moderate depths and the outputs of hoe decrease with an increase in depth.

6. Tractor

Types of Construction Equipment
Tractor
  • It is an important piece of equipment for the earth’s movement.
  • They are either: Crawler mounted or wheel types.
  • Crawler mounted tractor is used for uneven and rough ground. When tractor operates best on smooth roads.
  • Tractors are used to pull or push other equipment. Hence they are provided with various attachments such as dozer, scraper, narrow, plow, etc.

7. Bull Dozer

  • A bulldozer is one type of the tractor, fitted with a blade at the front.
  • It is used to move, compress, or tear the material.
  • It is used for the following purposes:
Types of Construction Equipment
Bull Dozer

i) To clear the site of work.

ii) To make the land level.

iii) to prepare pilot roads through mountains.

iv) it is used to excavate the material and haul for a distance of about 100m.


8. Graders

Types of Construction Equipment
Graders
  • The main function of the grader is leveling and finishing of earthwork.
  • It is used for the maintenance of earth roads.
  • A blade can be attached to the grader.

9. Scrapers

  • The equipment consists of a large bucket called the scraper and is attached to a tractor. Its capacity varies from 3 to 9 m3.
  • The scraper has a cutting edge or blade at the bottom and it is possible to dig earth to a depth of about 25 cm.
  • The scraper ‘combines three operations, namely, digging, conveying and dumping.

10. Rippers

  • It is used to break up the ground and to pull up the roots.
  • The loosened material can then be removed by the scraper.
  • It is sometimes, attached to a tractor. It can be used to level the bed of rock mine.

11. Trucks

  • Used for transporting earth, sand, aggregates, bricks, cement bags.
  • It is used for long-distance transportation.

12. Wagons

  • These are suitable for laying materials in layers.
  • Suitable for the construction of earthen darns, embankments, highways, etc.

13. Dumpers

  • Used for transporting sand, gravel, aggregates, earth, etc.
  • It is suitable for transporting material for short distances on rough roads.

14. Cableways

  • It is suitable to transport material in a narrow gorge.
  • In this method, a carrier (bucket) moves on one or two cables.

15. Aerial Tramway

  • In this method, a bucket is suspended from wires supported on towers at the ends.
  • It is suitable for long-distance transportation.

16. Belt Conveyors

  • It is used to transport sand, aggregate, concrete, soil, etc. from one place to another, continuously at a constant rate.
  • It is suitable for uneven ground.

17. Buckets

Types of Construction Equipment
Buckets

  • Suitable for transportation of liquid or semi-liquid matters.

18. Concrete Chutes

  • Used for transportation from a higher level to the lower level.

19. Buggies

  • It is used for transporting concrete.
  • Its capacity is 4 to 9 cu. ft.
  • It works on the smooth and hard road surface.

20. Mobile Crane

  • They are used in big construction projects for lifting heavy loads.
  • It is used for loading and unloading of materials in coal mines.
  • Loading and unloading of ships
  • Also, they are used to the load from ground level and place it into the trucks.

21. Tower Cranes

  • These are cranes of swing jib type and are mounted on high steel towers.
  • The height of the tower maybe 25 to 30 m and these cranes are found to be suitable in the construction of the tall buildings in congested areas.
  • The ground is required for such cranes are very small.

23. Winch Machine

  • A winch is a mechanism in the shapes of a cylinder or drum, over which rope or chain is wound.
  • Sometimes it is used only for raising and lowering. It is sometimes referred to as a host.

Types of crusher are:

  • Jaw crusher
  • Roll Crusher
  • Cone Crusher
  • Impact Crusher etc.

26. Ball Mills:

  • In a ball mill, metal rods are fixed in a metal cylinder.
  • Stone pieces are fed into the cylinder and fine aggregates are obtained at the outlet.
  • Sometimes, instead of steel rods, steel balls are fed into the cylinder, then it is called ‘ball.
