Earth Movers : That Dig in

Dirt, Helps to Build road and

Many More…

Earth Movers Equipment

What are Earth Movers• Earth movers are devices which are used to dig, push, and

transport earth. Earth movers can be designed to dig into the

earth with scoops, cutting blades, shovels, and sometimes

saw-like attachments which can be used for trenching and

breaking up very hard soil and rock.

• They can also push earth around a work site, as in the case of

bulldozers, and be used to carry earth to other locations, with

excavator buckets being an example of equipment which can

be used for transport.

Different Types of Earth Movers

• Excavators

• Cranes

• Bulldozers

• Tractors

• Backhoes

• Grader

• dumper truck

Excavators• An excavator is a construction vehicle used to dig or move large objects. An

excavator is designed for use on construction sites and is quite expensive to

purchase.

• Many smaller construction companies lease or rent these units to avoid the

expensive overhead costs. The lease and rental rates vary, depending on the

length of the contract, the location, and the volume of business with the

leasing firm.

• The more equipment

that a company leases

or rents from the same

firm, the better the

pricing will be.

Cranes• A crane is a machine that is capable of raising and

lowering heavy objects and moving them horizontally.

• One of the earliest versions of the crane to be developedwas the shaduf, first used to move water in Egypt aboutfour thousand years ago.

•

Bulldozers• A bulldozer is a heavy piece of earthmoving equipment which uses

a front-mounted 'dozer' blade to push soil forward and create a

level surface for construction sites.

• Technically, the word only applies to the front dozer blade, not

the entire machine. Some

sources suggest that the

power and noise of the

chassis suggested a

restrained bull, while others

point to the extreme medical

practice of bull-dosing.

Tractors• A tractor is a piece of heavy machinery that is designed to carry out some

type of work. The type of work this equipment can do depends on its size,

the type of attachments it has or can support, and the type of tasks it is

designed to accomplish.

• There are many enthusiasts who collect and restore antique tractors,

participate in clubs, and hobbyists who collect or build models. Many

people even use

their machines to

participate in

recreational sports

such as tractor

races and tractor

pulling.

Backhoes• A backhoe, also known as a backhoe loader, is a versatile piece of heavy

machinery used primarily for digging trenches and ditches on construction

sites

• Many construction companies consider the backhoe to be the workhorse of

earthmovers. It is often the only piece of heavy equipment brought onto

small to medium landscaping

projects.

Grader• A grader, also commonly referred to as a road grader, a blade, a maintainer,

or a motor grader, is a construction machine with a long blade used to

create a flat surface during the grading process

• Graders can produce inclined surfaces, to give cant (camber) to roads. In

some countries they are used to produce drainage ditches with shallow

V-shaped cross-sections on

either side of highways.

Dumper Truck

• On most construction sites, materials such as gravel, sand and fill dirt must

be brought in, while waste materials such as old bricks and excavated dirt

must be carried out.

• The bulk of this work is performed with specialized vehicles called dump

trucks. Dump trucks can be as small as a standard passenger truck or as

large as an 18-wheeler.

Earth Movers

Uses

• Utilized on construction sites and in mines

• Used for agricultural purposes

• Used in excavation, in manufacturing sites

• Faster way to perform major landscaping or repairs

on underground pipes

• Construction and maintenance of dirt roads and

gravel roads
