SHUTTLE CARBY : IQRA SHAFIQREG NO : 2014-MIN-4

SHUTTLE CAR• INTRODUCTION• DESIGN• LIMITATIONS• WORKING IN MINES

Introduction • A small profile car.• Underground mines.• Longwall mining and room and pillar mining.• Excavated ore from face to the outside of mine.• Electrically powered car equipped with variable frequency

drive.

OPERATOR COMPARTMENT It is a sitting area for the operator in the shuttle car. The operator changes hic position according to the direction of the

movement of shuttle car.

CABLE REEL COMPARTMENT A cable reel is a round, drum shaped object such as a spool used to carry various

types of electrical wires.  Cable reel which can also be termed as drums have been used for many years to

transport electric cables, fiber optic cables and wire products.

CONTROLLER• The controller takes power from the batteries and delivers it to the motor. • The accelerator pedal hooks to a pair of potentiometers (variable resistors), and

these potentiometers provide the signal that tells the controller how much power it is supposed to deliver.

• The controller can deliver zero power (when the car is stopped), full power (when the driver floors the accelerator pedal), or any power level in between.

TRACTION MOTOR• A traction motor is an electric motor used for propulsion of a vehicle, such

as an electric locomotive or electric roadway vehicle.

LIMITATIONS On board battery supplying to a dc motor.

Trailing cables to supply dc current.

Ac motors.

A combination of ac and dc power system.

WORKING IN MINES• A heavy duty unit designed to carry maximum load at

high speed.• Works with the help of electricity in association with

trailing cable.• Collects ore from continuous miner and supplies it to

feeder cable.
