APPENDIX 2

LIFTING

Lifting eyes are provided around the top flange of the unit for the attachment of suitable strops of equal
length. These should create an angle of no less than 600 to the top of the unit to avoid excessive loads on
the sides of the structure.

WARNING Care should be taken when attaching lifting equipment as the surface of the unit becomes
very slippery when wet.
