3. BUCKET CAPACITY
Bucket capacity is a measure of the
maximum volume of the material that
can be accommodated inside the bucket
of the backhoe excavator.

4. FRONT END LOADER
A front end loader is a type of tractor,
usually wheeled, sometimes on
tracks, that has a front-mounted wide
bucket connected to the end of two
booms (arms) to scoop up loose
material from the ground, such as
dirt, sand or gravel, and move it from
one place to another without pushing
the material across the ground.

5. 90 TON DUMPER
A 90 ton dumper truck
is primarily used to
transport materials to
and from a
construction site. It
has a capacity of 90
tons.

6. EXCAVATOR
Excavators are heavy
construction equipment
consisting of a boom,
dipper, bucket and cab on a
rotating platform known as
the "house". The house sits
atop an undercarriage with
tracks or wheels.

7. ELECTRIC SHOVEL
A power shovel is a
bucket-equipped
machine, usually
electrically powered,
used for digging and
loading earth or
fragmented rock and for
mineral extraction.

8. DIFFERENCE BETWEEN LONG TON AND SHORT TON
LONG TON:
1. IS A BRITISH TON
2. IT HAS A CAPACITY OF 2240Ib
SHORT TON:
1. US TON
2. CAPACITY OF 2000Ib

9. TONNAGE FACTOR
The tonnage factor provides the mechanism for the
conversion from volume of ore to weight of ore. In
the English system, the tonnage factor is normally
expressed as cubic feet per ton of ore. In the metric
system, the tonnage factor is the specific gravity of
the ore.

10. Why do we study mine machinery?
To allow us understand the principles of mechanical
engineering and electrical engineering for analysis,
design, manufacturing and maintenance of mining
equipment
