Excavatorsare heavy construction equipmentconsisting of a boom, stick,

bucketand cab on a rotating platform known as the "house".[1]The house

sits atop an undercarriage with tracks or wheels. cable!operated

ecavator uses winches and steel ropes to accomplish the movements. [#]

They are a natural progression from the steam shovelsand often calledpower shovels. ll movement and functions of a hydraulic ecavator are

accomplished through the use of hydraulic fluid, with hydraulic cylinders

and hydraulic motors.[$]%ue to the linear actuation of hydraulic cylinders,

their mode of operation is fundamentally different from cable!operated

ecavators.

crane is a type of machine, generally equipped with a hoist, wire ropes

or chains, and sheaves, that can be used both to lift and lower materials

and to move them hori&ontally. 't is mainly used for lifting heavy things

and transporting them to other places. 't uses one or more

simple machinesto create mechanical advantageand thus move loads

beyond the normal capability of a human. (ranes are commonly

employed in the transportindustry for the loading and unloading of

freight, in the constructionindustry for the movement of materials and in

the manufacturing industry for the assembling of heavy equipment.

+auling quipments like dump truck)or, -, dumper/ tipper truck* is a truck

used for transporting loose material )such as sand, gravel, or dirt* for

construction. typical dump truck is equipped with an open!bo bed, which is

hinged at the rear and equipped with hydraulic pistonsto lift the front, allowing

the material in the bed to be deposited )"dumped"* on the ground behind the

truck at the site of delivery.

compactor is a machineor mechanism used to reduce the si&e of

wastematerial or soil through compaction. trash compactor is often

used by a home or business to reduce the volume of trash.

0ormally powered by hydraulics, compactors take many shapes andsi&es. 'n landfillsites for eample, a large bulldo&erwith spiked wheels

called alandfillcompactoris used to drive over waste deposited by

waste collection vehicles )(2s*.

(2s themselves incorporate a compacting mechanism which is used

to increase the payloadof the vehicle and reduce the number of times it

has to empty. This usually takes the form of hydraulically powered sliding

plates which sweep out the collection hopperand compress the material

into what has already been loaded.

paver)paver finisher, asphalt finisher, paving machine* is a piece

of construction equipmentused to lay asphalton roads, bridges, parking

lots and other such places. 't lays the asphalt flat and provides minor

compaction before it is compacted by a roller.
