What is a wagon
tippler?
For what purpose
it is used ?
8/8/2019 WT Mukesh Final
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
8/8/2019 WT Mukesh Final
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).
8/8/2019 WT Mukesh Final
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.
8/8/2019 WT Mukesh Final
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.
8/8/2019 WT Mukesh Final
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.
8/8/2019 WT Mukesh Final
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.
