4. 
This trackless units operate on roads
and are tyre wheel mounted

5. 

Automobile units used in surface and
underground mines:-
Lhd :- when used as transporting unit, the
hauling distance should not exceed 150m

Shuttle cars :- the limiting distance for these
units are in the range of 1–2km

Low profile trucks and dumpers for their

Belt conveyors
Chain conveyors
Shaker conveyors
Cable belt

Belt conveyor is basically an endless strap
stretched between two drums. The belt carries
the material and transmits the pull. A belt
conveyor system essentially consists of steel
structure all along its length.

8. 
These types of conveyors have been designed
to withstand rigorous mining conditions
particularly at a working face, which is always
advanced ahead. These conveyors can
negotiate gradient of more than 18° i.e. more
than the belt conveyors usually negotiate.

9. 
The Pipe Conveyor is
an enclosed curve
going transportation
system for all kinds of
bulk materials. At the
loading and
discharging points,
the conveyor system
is identical with open
troughed conveyors.
