Main track & tippler platform rail size : 52 kg/m (156 ht, 67 hd, 136 flg)
No. of apron feeders and capacity : 2 nos. x 770 tph rated (850 tph design)
Atmosphere : Dusty
4. DESIGN RULES
4.1 For Tippler and Charger structural design BS 2573 Part 1:1983 is referred with
Wagon Mass for Cyclic Loading Gross: 92t (to allow for surcharge)
Tare : 25t
Wagon Mass for Non-Cyclic Loading Gross: 110t
Tare : 25t
Tippler structure is designed with classification A8 and fatigue life of 1 x 106 cycles.
4.2 For Tippler and Charger Mechanical design BS 2573 Part 2:1980 with classification
M8 is referred to.
4.3 Wagon Top Clamp mechanism shall be designed for load case combining 110t
wagon (strength case) and three (3) clamps only operating out of four.
5. FOUNDATION DESIGN
a) Metso Drawing: No. 2119 002 - Foundation Profile and Load Data for Wagon
Tippler
b) Metso Drawing: No. 2120 002 - Foundation Profile and Load Data for Side
Arm Charger
c) Metso Drawing: No. 5006 002 - Foundation Profile and Load Data for Apron
Feeder
b) Concrete loading based on live loads x 1.4 to give an equivalent dead load.
c) Buffer loads to be based on charger along with single wagon at 2/3 of rated
travel speed with an impact factor 2.
6. TIPPLER DESIGN
The design of the tippler is Hi-Lift XL Rotaside type with hydraulic drives (3 pinions,
one end only), hydraulic clamp gear (4 clamps) and integral weigh bridge. Hydraulic
power unit is housed in a room adjacent to tippler and supply of hydraulic power to
clamp gear is through festoon arrangement.
3 nos. of locomotives, each with 130t maximum gross weight can pass over tippler
platform at 8 km/hr maximum speed, when tippler is in lowered (grounded) position.
Tip Cycle:
Return Cycle:
7. CHARGER DESIGN
The design is Side Arm Charger type with 3 pinions meshing with a ground mounted
rack. Each pinion is driven by a hydraulic motor. Disc brakes are provided as integral
units with hydraulic motors. Charger consists of a fabricated frame supported by 4
support rollers and guided by 2 pairs of rollers acting on the sides of a ground
mounted spine bar. Arm luffing is achieved by means of a hydraulic cylinder.
Hydraulic power unit is mounted on the charger frame and electric power supply to
the charger is through a festoon arrangement.
At the in haul side a powered clicking stop is provided to prevent undue rolling of
wagon/ rake towards tippler and a runback stop is provided to prevent rolling back of
rake so that it remains within the reach of the charger. Runback stop is also provided
at the out haul to prevent rolling back of ejected wagon towards tippler. Stops can be
manually retracted, if wanted.

The design of Apron Feeder is shaft less tail wheel design and the tail wheels are
sealed for life. The feeder also consists of sealed crawler tractor type chain of drop
forged induction hardened steel links, hardened bushings and pins, heavy duty cast
manganese steel pans and life lubricated rollers. The apron feeder is fixed speed
type and is driven by electro-mechanical drive.
9. ELECTRICAL
Wagon Tippler:
Clamp gear & hydraulic clicking stop: 1 x 37 kW 4P AC for hyd. power unit
Apron Feeder:
Water Pump: 1 x 22 kW 2P AC
1) MCC :-
i. The MCC for wagon tippler, side arm charger and apron feeder drives and auxiliaries
shall be as per single line diagram drg no.2119 901.
ii. The MCC will be housed in the electrical panel room adjacent to the side arm charger
track and the operator’s control room shall be located above this room.
iii. Power supply to the MCC for total load drawn by the equipment will be provided to
Metso’s MCC panel with adequate healthy and stable supply.
iv. All other voltages as required for the system shall be generated by Metso.
2) Tippler and side arm charger is provided with hydraulic drives, as per the hydraulic schemes.
3) A small self-standing PLC panel catering for above drives is provided inside the Operator’s
control room.
4) Main Control Desk shall be in Operator’s control room and also separate control for charger in
Operator’s cab on side arm charger carriage.
5) Various limit switches for safety and interlocks of the wagon tippler, side arm charger and apron
feeder operation.
6) All related power and control cabling for above drives and auxiliaries, along with festooning
cables for side arm charger.
7) Local Push Button Stations are provided for above drives for maintenance purpose.
8) Dust Suppression System control panel , shall be supplied by DS system vendor (or part of
MCC). The incoming supply for the panel will be tapped from wagon tippler MCC.
9) MCC room and operator’s control room are considered to be provided with air conditioning units
of window type.
10) Power socket for welding etc. will be provided at convenient point for maintenance purpose.
11) Adequate lighting will be provided in the MCC room and the operator’s control room.
Control of the tippler will be from the track side control station for normal (automatic)
operations.
A control station will be provided on board the charger to enable positioning of the
rake of wagons ready for automatic operations. This station will also be used for
maintenance and setting up purposes.
A push button station will be provided adjacent to the tippler to provide for
maintenance and setting up purposes.
Emergency stop push buttons will be provided on the control/pushbutton station and
