Main Components Hydraulic Excavator
Exavator consist of various major components and have different fittings socan work well. The main components of the excavator made with durability andhigh strength so that it can withstand the severe operating conditions in the longlong time. The main components of the excavator consists of:
a. Track Rolller Frame Track roller frame is the main frame that is used to install components undercarriage
b. Main Frame Main frame is the main frame to install the track roller frame and holder for all major components of excavators.
c. Operator compartment / cabin The cabin is an operator space and the control equipment and monitors. This room made as comfortable as possible to reduce operator fatigue with equipped with air conditioner.
d. Counterweight Counter is a ballast weight mounted to the rear excavator maintain balance while lifting weights excavators
e. Boom Boom is an arm that is connected to the mainframe to support the stick and bucket.
f. Stick Stick a bucket arm mounting and other work equipment driven by hydraulic cylinders.
g. Undercarriage Undercarriage is a series of components that enable mobile excavator with the track links, track rollers, final drives and travel motors.
h. Powerlink Powerlink is the equipment used to connect between the sticks and bucket or other work equipment.
Excavator Hydraulic System on
Excavator Hydraulic System on works by converting mechanical energy from engineinto electric energy by the hydraulic fluid pump and forwarded to the control valve toset the cylinder and hydraulic motor. Subsequently forwarded to the implement hydraulic flowand hydraulic motors to turn back the fluid energy into mechanical energy.

Based on the function, the hydraulic system on the excavator can be grouped into three,namely:a. Hydraulic Cylinder Hydraulic cylinder that drives the work tool to do work which consists of three types, namely:
1. Boom Cylinder
2. Stick Cylinder
3. Bucket Cylinder
1. Boom Cylinder
2. Stick Cylinder
3. Bucket Cylinder
b. Swing Motor and Drive Hydraulic oil which is controlled by control valve allows the swing drive and
motor cooperate rotate 360 degree excavator.c. Travel Motor and Final Drive Hydraulic oil which is
controlled by control valve and swivel joint enables the motor travel and final drive excavators move
forward and backward.
Bucket & Work Tools
Buckets and work tools that can be mounted on Exavator consists of various types in accordancewith the
application of each excavator. A common work tools mounted on Excavatorare:
1. Excavation (X) Excavation work to dig and bucket load of material such as soil soft and medium and
clay. Consists of an adapter tip, wear resistant alloy steel cutting edge (tip), wear plate and high grade
steel side bar.

2. Extreme Excavation (EX) Extreem Excavation work to dig and bucket load of solid material and
abrasive such as a mixture of rock and soil, a mixture of sand and clay, mixed sand and stone, coal, lime
and metal ore (ore). Having more Ground Engaging tools large, steel alloy wear resistant cutting edge,
wear plate and side bar.
3. Special Application Bucket Special bucket application consists of various types such as ditch cleaning
bucket (tiltable), skeleton bucket (heavy duty) and trapezoidal bucket. Each of the buckets have
superior performance in specific applications.
4. Quick Coupler Caterpillar quick coupler allows the operator to easily replace-change work tools so
that the hydraulic excavator can have multiple purposes.5. Work Tools Various worktool can be
mounted on excavators such as hammers, crushers, PULVERIZER, shear, multiprocessor and grapple.
