•
For lifting unbalanced loads, use ropes of different lengths or chains with
adjustable length.
•
Check each time the conditions of all lifting equipment used and discard it if
not in perfect working order.
•
Do not knot or twist the ropes so as not to reduce the lifting capacity or
produce torsional effects on the load being lifted.
•
Use the utmost caution and remain at a safe distance from lifted actuator
unless absolutely necessary; do not stand or pass under suspended loads.
•
Pay attention in putting under tension the ropes to prevent the load shifting
sideways in an uncontrolled manner.
•
Use slings of such length that the angles of the leg from vertical are as narrow
as possible (
α
MAX < 20°).
•
During handling, do not transport the suspended actuator above staff
members in charge of the operation.
!
WARNING
Do not use the lifting eyelets on actuator to lift valve + actuator assembly.
