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 (
MAX < 20°).
•
During handling, do not transport the suspended actuator
above staff members in charge of the operation.
DO NOT USE the lifting eyelets on actuator to lift valve +
actuator assembly
