What is a wagon

tippler?

For what purpose

it is used ?


3/19

WAGON TIPPLERIt is a deep underground structure which is subjected to direct load from

loaded wagon/loco due to the rake movement over it, in addition to load

due to coal filled hopper and lateral earth pressure. The earth pressure to

be considered here for design shall be due to earth pressure at rest (K0).

For calculation of coal load on moving conveyor, a multiplication factor 1.6

shall be used to take care of inertia force, casual overburden and impact

factor etc.

Thus, coal load per unit length of each moving conveyor

= 1.6*(Cr/Vcb )*(1100/800).

Where, Cr = rated capacity of conveyor system,

Vcb = conveyor belt speed.

Unit weight of coal shall be assumed as 1100 Kg/m3 instead of 800 Kg/

OPERATION PHILOSOPHY


14/19

Step1-Loco should have to brought

fully loaded 58 numbers wagons (BoxN type), nearer to rail table i.e. with in

the reach of Side Arm Charger

(SAC).

Step2- Engine have to removed

through loop line, by- passing railtable (consisting load cells for

weighing).


15/19

Step3- Side arm charger arm will

automatically (hydraulic operated) clamp

with wagon rakes, and will drag full racknearer to rail table. Long travel of SAC took

by Hydraulic driven rack-pinion system.

Step4- One number wagon will be manually

de-clamped from rake and side arm charger

will slowly placed the loaded rake on-to therail table and the 04 i.e. two pair photo cell

will verify the perfect positioning of wagon

on the rail table.


16/19

Step5-As soon as photo cell permits, the four number

hydraulic operated clamps , moves down and hold the

entire wagon along with rail table from bottom, in meantime side arm charger de-clamped from the wagon.

Step6- The wagon tippler drive start the tippling

operation and on the end-arm by side type tippling

system, whole rail table along with loaded wagon tilting

started. As soon as the tippling angle reaches up-to

110 degree, after getting clearance with rail table, the

horizontal arm of side arm charger lifted up (i.e. 90 O).The side arm charger will start to move back towards

rack, and the tippler will continue the tippling activity for

up-to 150 degree.


17/19

Step7- The tippler will complete the tippling of wagon

i.e. unloading of coal into WT hopper (Capacity -02

fully loaded wagon), in the same time frame the side

arm charger , reaches nearer to the loaded wagon

rakes.

Step8- Side arm charger again started the same

sequences of Step1 to step-7, by holding the entirerakes, dragging nearer to rail table, manual de-

clamping of one wagon and then placing of wagon

up-on rail table. In the same time frame the rail table

will return back to its original position , clamps will beremoved from empty wagon.


18/19

Step9- While placing loaded wagon from IN-

HAUL track on to rail table, the side arm charger

(SAC) slowly push empty wagon ahead in OUT-

HAUL track, and at last SAC, will imparts a quit

higher force on empty rack , in order to moving

farther from rail table or automatically clampingwith any existing wagon.

Step10- From the hopper ,through apron feeder,

coal cutting will took place and by conveyingsystem , coal will be feed in to crusher house.
