The boiler body can be moved with a
fork lift by placing the forks under the
boiler supporting framework.

For lifting using a rigging crane, use only
the lifting provisions supplied near the
front and rear of the boiler.

When lifting the boiler using chains, make
sure that at least two chains are load-bearing.
Lift up very carefully.

Maintain less than a 45 degree angle with
the vertical when lifting the boiler with chains
or cables.

The rigging crane must be operated by trained personnel.

Make sure to secure the boiler body to the truck floor using straps.
