Figure 8 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 (αMAX < 20°).
• During handling, do not transport the suspended actuator above staff members in
charge of the operation.
