Installation
•
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.
For the transport of OLGA actuators with hydraulic manual hand-pump, when it was
necessary put in horizontal position the tank of MHP, to avoid leakage on oil level stick,
substitute these with a blind-plug during the transport (a specific warning label for
transport in horizontal position is attached on the MHP body); remove the blind plug
and restore the dipstick before operate the actuator with MHP. Biffi hydraulic manual
hand-pump must be maintained with tank in upper position to operate the actuator with
MHP correctly.
