Explain the uses of the following mechanical equipment on site, back actor, face shovel, skimmer,concrete pump, tilting drum and bull dozer ?

1. Back actor: A back actor, also known as a backhoe, is a piece of excavation equipment that is commonly used on construction sites. It consists of a digging bucket on the end of a hydraulic arm, which is attached to the back of a tractor or other vehicle. Back actors are used for digging trenches, foundations, and holes, as well as for loading and moving materials.

2. Face shovel: A face shovel is a large excavating machine that is used for digging and loading materials. It has a bucket attached to the end of a hydraulic arm, which is mounted on a rotating platform. Face shovels are commonly used in mining, quarrying, and earthmoving operations.

3. Skimmer: A skimmer is a type of construction equipment that is used for removing excess material from the surface of a site, such as soil, gravel, or debris. Skimmers are often used in road construction, landscaping, and site preparation.

4. Concrete pump: A concrete pump is a machine that is used to transfer liquid concrete from a mixer truck to the desired location on a construction site. Concrete pumps are commonly used in large construction projects, such as high-rise buildings, bridges, and dams, where the concrete needs to be pumped to a high or hard-to-reach location.

5. Tilting drum: A tilting drum is a type of concrete mixer that has a drum that can be tilted to pour out the mixed concrete. Tilting drums are commonly used on construction sites for mixing and pouring concrete for various applications, such as foundations, slabs, and walls.

6. Bull dozer: A bulldozer is a heavy-duty construction machine that is used for pushing, digging, and moving large quantities of earth, soil, or other materials. Bulldozers are commonly used in earthmoving, road construction, and land clearing projects. They have a large blade at the front that is used to push and move materials, as well as a ripper at the back for breaking up hard ground.

1. Back Actor:

- Used for excavating trenches, footings, and foundations.
- Features a hydraulic arm with a bucket mounted on the back of the machine.
- Can reach and dig below ground level.

2. Face Shovel:

- Used for excavating large volumes of soil or rock.
- Features a large dipper bucket that is attached to an arm and boom.
- Can load material into dump trucks or other equipment.

3. Skimmer:

- Used for removing shallow layers of soil or debris.
- Features a wide, flat blade that scrapes along the ground surface.
- Typically used for leveling, removing topsoil, or clearing areas.

4. Concrete Pump:

- Used to pump freshly mixed concrete to high elevations or hard-to-reach areas.
- Consists of a hopper, pump, and flexible hose.
- Can convey concrete long distances and deliver it at a controlled rate.

5. Tilting Drum:

- Used for mixing and transporting concrete.
- Features a rotating drum that is tilted to discharge the concrete.
- Can provide continuous mixing and efficient delivery to the worksite.

6. Bull Dozer:

- Used for earthmoving, grading, and clearing land.
- Features a large, blade-like structure mounted on the front of the machine.
- Can push, pile, and level soil, rock, and other materials.
