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.
Wagon Top Clamp Force: 5.66t Normal per clamp
: 7.55t Maximum per clamp with only 3 out of 4 clamps
sharing considered for design
Clamping Angle
: Fully engaged at 700 tipping angle
Cylinders locked at 800 tipping angle for the remainder of
the tip & return cycle until at 800 tip angle on return the
cylinders are unlocked and start retracting for 15 sec to
fully stroke in.

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.
