Construction Equipment
Classification:
• Earth moving equipment.
• Hauling equipment.
• Hoisting equipment.
• Conveying equipment.
• Tunneling and rock drilling equipment.
• Pumping and dewatering equipment.
• Pile driving equipment.
• Aggregate and concrete production equipment.
Excavation and Earth moving equipment:
Power Shovel:
• Excavate the earth and to load the trucks.
• Capable of excavating all types of earth {Exception- hard rock}.
• Size = 0.375m3 to 5m3. शोवेल ची एका टाइम ची capacity आहे .
• Size of power shovel is indicated by the size of dipper/Bucket.
• generally expressed in m3
Application:
• Suitable for close range of work.
• Can remove big size boulders.
• Used in digging in gravel banks, clay pits, digging cuts in road works etc.
Factors Affecting output of power shovel:
• Class of material
• Depth of cutting
• Angle of swing
• Job condition
• Management condition
• size of building units
• skill of the operator
• physical condition of the shovel
,Back Hoe:
• Also known as HOE, back shovel and pull shovel.
• It is used to excavate below the natural surface on which it rests.
• Generally, used to excavate trenches, pits for basements and also for works,
which requires precise control of depths.
Drag Line:
• The drag line is so name because of its prominent operation of dragging the
bucket against the material to be dug.
• Unlike the shovel, it has a long light crane boom and the bucket is loosely
attached to the boom through cables.
• Because of this construction, a dragline can dig and dump over larger
distances than a shovel can do.
• Drag lines are useful for digging below its track level and handling softer
materials.
, Application:
• It is the most suitable machine for dragging softer material and below its
track level.
• It has long reached.
• It is mostly used in the excavation for canals and depositing on the
embankment without hauling units.
Calm Shell:
• This is so named due to resemblance of its bucket to a clam which is like a
shell-fish with hinged double shell.
• The front end is essentially a crane boom with a specially designed bucket
loosely attached at the end through cables as in a drag line.
• The capacity of a clam shell bucket ls usually given in cubic meters.
Application:
• Used for handling loose material such as crushed stone, sand, gravel, coal
etc.
• Main feature is vertical lifting of material from one location to another.
• Mainly used for removing material from coffer dam, sewer main holes, well
foundations, etc.
