Nirman Vibhag.
Engineering Department of government responsible
for all the construction related work like
maintenance and planning of roads, bridges and
Govt. Buildings.

6. EARTH MOVINGMACHINERIES
• Earth-Moving Machinery are the
machines and attachments derived
machinery designed for loosening,
picking-up, moving, transporting
and/or distributing earth, or to
grade earth and rock. Among the
machines included here are tractor-
dozers, loaders, backhoe-loaders,
excavators, dumpers, trenchers,,
cable excavators, and rollers.

7. TPES OF EARTH MOVING MACHINERIES
1. Excavators
2. Backhoe Loaders
3. Bulldozers
4. Skid Steer
Loaders
5. Motor Graders
6. Trenchers

8. BACKHOE LOADER

10. BACKHOE LOADER
• Consists of a tractor unit fitted with a loader-style shovel/bucket on the front
and the back.
• Small size and versatility, backhoe loaders are very common in urban
engineering small construction projects (such as building a small house, fixing
urban roads, etc.)
• Similar to and derived from what is now known as a TLB (Tractor-Loader-
Backhoe), which is to say, an agricultural tractor fitted with a front loader and
rear backhoe attachment.
• The true development of the backhoe actually began in 1947 Wain-Roy
Corporation of Hubbardston, Massachusetts.
• 1947 Wain-Roy Corporation developed and tested the first actual backhoes.

11. USE OF BACKHOE LOADER
• Construction sites
• Small demolitions
• Light transportation of building materials
• powering building equipment,
• Digging holes/excavation
• landscaping breaking asphalt
• Paving roads.
Often backhoe bucket can also be replaced by breaker
Simplified attachment mounting, increasing the machine's utilisation
Front assembly may be a removable attachment or permanently mounted.

12. PARTS OF MACHINE

13.  The Tractor
• Designed to move easily over all kinds of rough terrain.
Powerful, turbocharged diesel engine, large, rugged tires and a cab with basic
steering controls (a steering wheel, brakes, etc.). Backhoe cabs are either
completely enclosed or have an open canopy structure to give the operator
protection.
 The Loader
• The loader is attached in the front
• powerful dustpan or coffee scoop. You usually don't dig with it; use to pick up
and carry large amounts of loose material. It's also used to smooth things over
like a butter knife, or to push dirt like a plow. The operator controls the loader
while driving the tractor.
 The Backhoe
• main tool of the backhoe loader.
• Used to dig up hard, compact material to lift heavy loads as a sewer box

loader.

15.  MAINTENANCE – maintenance
may be defined as all actions which
have the objective of retaining or
restoring an item in or to a state in
which it can perform its required
function. The actions include the
combination of all technical and
corresponding administrative,
managerial, and supervision actions.
MAINTENANCE

16. TYPES OF MAINTENANCE
• BREAKDOWN MAINTENANCE- waits until equipment fails and repair it.
• PREVENTIVE MAINTENANCE – it is a daily maintenance (cleaning,
inspection, oiling and re-tightening), to retain the healthy condition of equipment
and prevent failure
• Periodic maintenance (time based maintenance-TBM)- Periodic inspecting,
servicing and cleaning equipment and replacing parts to prevent sudden failure and
process problems.
• Predictive maintenance predictive maintenance is condition based maintenance
• CORRECTIVE MAINTENANCE –. Equipment with design weakness etc is
corrected

17. NEEDFOR MAINTENANCE
To Ensure machine
provide its desired function
Easy going no sudden failure
Maintain the working effiency of machine

18. MAINTENANCE OF TATA 497TC
 ROUTINE SERVICE – DAILY
• Check engine oil level
• Check fuel level in fuel tank and secure the tank cap.
• Check coolant level in radiator
• Check for leakage of coolant, fuel and lubricating oil and rectify.
• Check all instruments for proper functioning
• Check coolant level in radiator, top-up if necessary and secure radiator cap.
• Lubricate controls to the fuel injection pump by using oil can.
• Check oil level in FIP
• Check the oil level in the sump
• Clean air cleaner.
• Check and tighten if necessary: delivery valve holders, injection pressure lines,
• Check connections of starter motor and alternator and tighten if necessary.
ENGINE FOR BACKHOE LOADERS

19. • Check for leakage of fuel at: fuel lines
• Remove and clean engine breather cap strainer in kerosene oil and by blowing air in
reverse direction and refit.
• Tighten cylinder head nuts (with engine warm) and in the correct sequence. Check valve
clearance and adjust if necessary.
• Check condition of alternator and fan belt and adjust tension, if necessary.
• Start engine and check:
• (watch for any unusual noise).
• Alternator and regulator operation (watch battery charging indicator lamp).
• Oil pressure.
• REGULAR SERVICES TYPE
 SERVICE AT 300-320 HOURS AND REPEATING AT EVERY 300 HOURS
• Change oil in sump, drain off while still hot

20. FORMULA TO BE ADOPTED FOR CONDEMNATION
OF ROAD / BRIDGE CONSTRUCTION MACHINES:
• Recommended life of machine - X
hours/km.(see introduction manual)
• Cumulative life actually achieved by the machine – A hrs/km
• Recommended life of machine in years - Y years(IM)
• Number of years the machine is old ( taking year of purchase
in consideration ) - B years
• A/X + B/Y
• Then life for condemnation = -----------------* 100%
2
• NOTE : If life calculated as per above formula is more than
100% the machine may be considered for condemnation.

21. EXAMPLE - To determine the tyre life with the
following condition of working (IMM)
• Maintenance, average - 1.0
• Speed 45 km ( maximum) - 0.8
• Curves, moderate - 1.0
• Surface, soft earth, some rock- 0.8
• Load, 20% overload- 0.8
• Wheel position, driving bottom dump- 0.7
• Grades, 10% max. firm surface- 0.8
• Misc. condition, none- 1.0
• Tyre life : (6000 hrs. or 100000 km ) *
1.0*0.8*1.0*0.8*0.8*0.7*0.8*1.0= 1720 hrs. or
28672 km.
