To facilitate pole hoisting and to improve working safety it is indispensable that
the casings be positioned correctly with respect to the lifting equipment.
Using the appropriate lifting equipment, position the chamber casing so that:
S The centreline of the chambers is perpendicular to the plane of the lifting
equipment,
S The distance between the casing and the lifting equipment is greater than
the total length of the column fitted to the chassis "L" + 2 m.
NOTE: The cradle on the first chamber will be used in the column-
