Lifting Points for ALGAS-QA
•
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.
