This document discusses various types of modern construction equipment used in projects. It describes earth moving equipment like bulldozers, trenchers, draglines and their functions. It also covers hoisting equipment like cranes and dredging equipment like backhoe dredgers and cutter suction dredgers. Finally, it discusses concrete equipment like ready mix concrete machines and boom concrete pumps used to efficiently transport concrete on large job sites.

MODERN CONSTRUCTION EQUIPMENTS

2. INTRODUCTION
• EARTH MOVING EQUIPMENT
• EXCAVATING EQUIPMENT
• HOISTING EQUIPMENT
• CONVEYING EQUIPMENT
• TUNELLING EQUIPMENT
• MARINE DREDGING EQUIPMENT
• PUMPING EQUIPMENT

3. BULL DOZERS
A bulldozer is a crawler tracked tractor)
equipped with a substantial metal plate
(known as a blade) used to push large
quantities of soil, sand, rubble, or other such
material during construction or conversion
work and typically equipped at the rear with
a claw-like device (known as a ripper) to
loosen densely-compacted materials.

4. ANGLED BULL DOZERS
 Spreading earth fill .
 Clearing, opening up pilot roads .
 Back filling trenches .
 Clearing construction sites .

6. TRENCHERS
 Trenchers, or ditchers as they are sometimes
called, are similar to excavators in the sense
that they penetrate the earth, breaking soil and
rock, and remove it from the ground.
 They differ from excavators in that the soil is
removed in one continuous movement.
 Trenchers are specifically used for digging
trenches for pipes, but other machines have
been improvised in the past to serve this
purpose.

7. DRAG LINE
o Dragging softer material and below its track level
o It is very useful for excavating trenches when the sides are permitted to establish their angle
of repose without shoring.
o It has long reaches.
o Excavation for canals and depositing on the embankment without hauling units

8. Construction Equipments

9. • 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.

12. SIDE DUMP TRUCK:
 Dumping is through the sides of the truck
 Suitable for hauling wet clay, sand, gravel, quarry rocks.
 Suitable for long chase trucks .

14. TUNNELING EQUIPMENT
TRUCK MOUNTED DRILL:
 Truck mounted
 Easy mobility
 Depth – 15 m
 Holes along angle &
vertically down

15. PILE DRIVING RIGS
• Pile Driving Rigs provide basic operation of lifting the pile, holding the pile in position,
hammering it into the ground or of pulling it out of the ground and guiding the pile in the
desired direction of movements.
• It supports the boom, the winch, mechanism, driving hammer, the guiding leaders and a
platform for mounting the auxiliary equipment such as jet pumps, drilling auger etc.,

 It is mostly used in hilly regions to transfer goods
.

19. BACK HOE DREDGER
 It is usually mounted on a floating platform .
 Production rate - 100 - 400 CU.M/HR
 Bucket size - 1 T0 6 CU.M
 Depth - 18 M
 SUITABLE FOR ROCK MATERIAL, TRENCHES ETC.,

20. BACK HOE DREDGER

21. CUTTER SUCTION DREDGER
 3000 CU.M / Hr Output capacity & 6 km pumping range

22. TRAILOR SUCTION DREDGER
 300 to 11000 CU.M/Hr output capacity & depth –10 to 30 m

23. SPRAYING AND PLASTERING EQUIPMENTS
 Plaster spraying allows a plasterer to
skim a drywall more than five times faster
than using a hand float to apply it.
 Although classic gypsum-based plaster can
be sprayed if it is "spray grade," most
plaster sprayers prefer the organic-based
pre-mixed plaster packaged in a plastic bag
because the plaster spraying machine does
not need to be cleaned out after the job is
finished, providing that plaster is kept
moist.

24. READY MIX CONCRETE
EQUIPMENT
• Increases the efficiency of concrete by mixing in proper proportion.
• Poured in short interval of time .
• Wastage is reduced .
•

26. BOOM CONCRETE EQUIPMENT
• A concrete pump is a machine used for transferring liquid concrete by pumping. There are two types of
concrete pumps.
• The first type of concrete pump is attached to a truck or longer units are on semi-trailers.
• It is known as a boom concrete pump because it uses a remote-controlled articulating robotic arm (called
a boom) to place concrete accurately.
• These are used on large construction to pump concrete in large quantity .

28. EXAMPLE OF PUMP PERFORMANCE
• Vertical reach of boom: 41.9 meters (137 ft).
• Horizontal reach of boom: 38.0 meters (124.7 ft)
• Pumping rate: 140 cubic meters per hour (180 cuyd/h).
• Concrete pressure: 70 bar (7,000 kPa; 1,015 psi).
• Cylinder length: 2,100 mm (82.677 in).
• Cylinder diameter: 210 mm (8.268 in).
• Number of substitutions of strokes per minute: 27.
• Number of outriggers legs: 4.
