Caterpillar D Series

The CAT (Caterpillar) 420D and 430D backhoe loaders
are the high performance machines in the D series
lineup.  The 420D boasts 85 HP and a backhoe digging
depth of 14 feet when equipped with a standard
stick.

The 430D offers 94 HP and a backhoe digging depth
of 15 feet when it is equipped with a standard
stick.  By using an extendible stick, you can
push the digging depth of the 420D to 18 feet and
the depth of the 430D to 19 feet, which is very
impressive to say the least.

Both D series machines are available in IT
(Integrated Toolcarrier) configurations for
applications that benefit from a parallel lift
loader linkage and the versatility of quick work
tool changes through the use of a versatile
hydraulic quick coupler.  Applications include the
use of pallet forks, material handling arms,
brooms, and even buckets.

The new and improved pilot operated hydraulic backhoe
and IT loader controls will help to ensure smooth,
precise operation with reduced effort on behalf of
the operator.  These backhoes use excavator type
joystick controls, and an optional pattern change
valve which allows you to select the patern of
control.

The 205 degree rotation that is offered by the
backhoe bucket linkage will make it easier to dig
vertical walls and clamp material when loading
trucks.  The rotation with the D series is 40
degrees more than with the C series.  Now, the
backhoe buckets feature a single pin position,
with the bucket link featuring an integrated
lifting eye as well.

The optional quick coupler you can get for the
backhoe will allow fast changes of working tools
for increased versatility and flexibility in
almost all applications.

Both of the D series backhoe loaders use the
turbocharged, direct injection, four cylinder diesel
engine, with a displacement of 4.0 liters.  This
engine offers superior lug performance which is
mostly due to the responsive fuel injection
system.

The standard power shuttle transmission provides
four forward speeds and four speeds in reverse
as well.  Fully synchromesh in all gears will
permit on the go shifting, while the forward and
reverse electric power shuttle will provide
instant direction changes through powered
clutches.

The auto shifting feature will automatically
shift between second gear and the highest gear
selected for ease of operation.  The auto shift
feature has five forward and three reverse gears,
with a transmission kick switch on the lever of
the loader control.

With D series loaders, you'll also have the choice
of standard two wheel drive or all wheel drive,
which you can engage easily on the go, under
heavy load, by pressing a switch that is located
on the front console.

The D series loaders from CAT are very fast and
versatile as well, as they will move faster than
most types of backhoes on the market.  The
diesel engines are very fast, while the machine
has enough traction and control to keep you
moving even in wet or muddy conditions.

The variable load sensing hydraulic system will
adjust the flow and pressure of the machine to
meet the demands of work with an increased
pressure of 3,300 PSI.  The hydraulic system is
tuned to work efficiently with the engine, and
it provides full hydraulic force to the working
tool on hand at any engine speed you desire.

Unlike other backhoe loaders, the D series will
reduce demands on the operator, cut fuel consumption
in half, reduce wear on the engine, and allow
for quieter operation.  To make a long story
short - the D series from CAT are among the best
backhoe loaders that money can buy - bar none.

Bulldozer

The bulldozer is a very powerful crawler that is
equipped with a blade.  The term bulldozer is often
used to mean any type of heavy machinery, although
the term actually refers to a tractor that is fitted
with a dozer blade.

Often times, bulldozers are large and extremely
powerful tracked vehicles.  The tracks give them
amazing ground mobility and hold through very rough
terrain.  Wide tracks on the other hand, help to
distribute the weight of the dozer over large areas,
therefore preventing it from sinking into sandy or
muddy ground.

Bulldozers have great ground hold and a torque
divider that's designed to convert the power of the
engine into dragging ability, which allows it to
use its own weight to push heavy objects and even
remove things from the ground.  Take the Caterpillar
D9 for example, it can easily tow tanks that weight
more than 70 tons.  Due to these attributes,
bulldozers are used to clear obstacles, shrubbery,
and remains of structures and buildings.

The blade
The blade on a bulldozer is the heavy piece of
metal plate that is installed on the front.  The
blade pushes things around.  Normally, the blade
comes in 3 varieties:
1.  A straight blade that is short and has
no lateral curve, no side wings, and can be used
only for fine grading.
2.  A universal blade, or U blade, which is
tall and very curved, and features large side wings
to carry more material around.
3.  A combination blade that is shorter,
offers less curvature, and smaller side wings.

Modifications
Over time, bulldozers have been modified to evolve
into new machines that are capable of things the
original bulldozers weren't.  A good example is
that loader tractors were created by removing the
blade and substituting a large volume bucket
and hydraulic arms which will raise and lower the
bucket, therefore making it useful for scooping
up the earth and loading it into trucks.

Other modifications to the original bulldozer
include making it smaller to where it can operate
in small working areas where movement is very
limited, such as mining caves and tunnels.  Very
small bulldozers are known as calfdozers.

History
The first types of bulldozers were adapted from
farm tractors that were used to plough fields. In
order to dig canals, raise earth dams, and partake
in earthmoving jobs, the tractors were equipped
with a thick metal plate in the front.  Later
on, this thick metal plate earned the name blade.

The blade of the bulldozer peels layers of soil
and pushes it forward as the tractor advances.
The blade is the heart and soul of the bulldozer,
as it was the first accessory to make full use
for excavation type jobs.

As the years went by, when engineers needed
equipment to complete larger jobs, companies such
as CAT, Komatsu, John Deere, Case, and JCB started
to manufacture large tracked earthmoving equipment.
They were very loud, very large, and very powerful
and therefore earned the nickname "bulldozer".

Over the years, the bulldozers got bigger, more
powerful, and even more sophisticated.  The
important improvements include better engines,
more reliable drive trains, better tracks, and
even hydraulic arms that will enable more precise
manipulation of the blade and automated controls.
As an added option, bulldozers can come equipped
with a rear ripping claw to break up pavement or
loosen rocky soil.

The best known manufacturer of bulldozer is CAT,
which has earned a vast reputation for making
tough and durable, yet reliable machines.  Even
though the bulldozer started off a modified farm
tractor, it rapidly became one of the most useful
pieces of equipment with excavating and construction.

HABITS THAT SHOW IMPROPER UPBRINGING OF CHILDREN

Dear Parents,
HABITS THAT SHOW IMPROPER UPBRINGING OF CHILDREN
Please, carefully look at the list below and identify where you may want to make amends on yourself or on the young ones you are bringing up.
Children, if not properly groomed may never get to the top in life, even if both parents are at the top of their careers.
Manners take you to where your education can't irrespective of your status, wealth or your reach or influence.
1) Going to your child's school indecently dressed. Think again.
2) Speaking rashly to your child's teacher.
3) Cursing, using foul language or swear words in front of your children.
4) Using makeup on children.
5) Dressing your little children up indecently (they loose their sense of Princesshood).
6) Putting earrings on your son's ears.
7) Your child hold the cup or glassware by the brim and you don't correct.
8) Your children don't greet and you just feel they will come around one day because they have a mood swing. ( You will be blamed for it)
9) Your children eat with their mouth opened and you feel they will grow up some day.
10) Your children bring home something you did not buy for them and you say nothing. (that is the beginning of stealing)
11) They talk back at you and you conclude it's okay since you are a 21st century Mummy. (You will hate yourself if they do that outside and they are disciplined )
12) They interrupt when you are speaking with another adult and you think they are bold and clever. (Its really bad manners)
13) They exercise authority over the nanny and domestic staff and you let them be. (that is bad parenting)
14) They say things like "my driver is on his way..."
I do not advocate that children should call your domestic staff aunty or brother, calling them by name when they are not young people is not poise either. The use of Miss, Mr or Mrs will look good on them.
15) Your children don't say a 'thank you' when they have been helped or served something and you are cool with that. (Bad parenting)
16) When your children cannot stand children who are less privileged.
18) When they pick their nose with their hands.
19) When they don't wash their hands after visiting the washroom or after returning from school or outside visits.
20) When your children take something from the fridge without taking permission. (Bad parenting)
21) When your children don't knock on closed doors and wait for a response before opening the door.
22) When your children don't collect from your hands items you brought in as you walk into your home.
23) When your children request for a bribe to carry out their home chores or extra task. (That is disgraceful )
24) When your children act like their grand parents irritate them.
25) When your children have not learnt to get up from the chair for the elderly or visitors to sit.
26) When your child tells a lot of lies. (You will both cry in the future)
27) When your child asks "who is that?" at a knock on your door instead of "please, who is there."
28) When your child is always seated by your visitors when being served drinks etc.
29) When your children still point their fingers at other people.
30) When your children play and jump around when prayers are going on.(age 4 above). Don't be a 21st Century parent who can't correct a child. Train your child in the way of the Lord so that when he grows up he will not depart from it. IT IS BETTER TO LET YOUR CHILDREN CRY AT AN EARLY AGE WHEN YOU CORRECT THEM, IF NOT YOU WILL BOTH CRY AT NIGHT WHEN THEY BRING DISGRACE TO THE FAMILY WITH BAD AND TERRIBLE BEHAVIOURS (PROVERBS 23:13).
Please circulate to all parents and grandparents that are on your contact list to assure us all a better future. God bless you.
