When filling the roller with mixed ballast, begin with the available pieces of steel and then
add the required amount of sand and water.
Distribute the ballast evenly.
Sand should be moistened with water when being filled. This will contribute to distributing
the sand evenly.
BALLAST COMPARTMENT
Fig. 26 Covers on the ballast compartment
1. Upper cover
2. Side cover
3. Plug
Fill the compartment from above.
Remove the upper cover (1).
Allow the side cover (2) to remain in place so that sand and water does not run out.
Remove the side cover when filling with pieces of steel.
Do not remove the plug (3), otherwise water will run out when the ballast is complemented with
water.
Complement the ballast compartment as required with crushed rock, sand and steel.
Water can be added to the sand when being filled. This will even out the sand and fill spaces
between the steel pieces.
