7.1 Lifting Recommendations
•
The lifting device and the sling must be suitably rated
for the actuator weight and dimensions
•
Do not use damaged sling(s)
•
The sling must not be shortened with knots or bolts or
any other makeshift device
•
For lifting purposes, use only suitable lifting tools
•
Do not drill holes, weld eye bolts or add any other type
of lifting device on the actuator external surface
•
Do not lift the actuator and valve combination with the
actuator lifting lugs
•
Every assembly must be estimated separately for a safe
and correct lifting
•
Avoid pulls or abrupt movements during lifting.
Avoid pushing the load
•
During lifting operations, do not handle the slings
and/or the actuator
Do not step underneath suspended load.
7.2 Lifting Instructions
Note: Indication of weight, centre of gravity,
lifting points are reported within specific project
documentation.
For non-horizontal actuator orientation, please consult
project specific documentation before lifting.
•
Prior to lifting the actuator, remove electrical power and
vent all pressure vessels (if present)
•
In case of Single-acting actuator, hook the double chain
slings on the lifting lugs, as shown in Fig 7.1.
•
In case of double-acting actuator, hook a double chain
sling on the lifting lug on the pneumatic cylinder and a
textile sling on the centre body closure flange as shown
in Fig 7.2.
The actuator must remain horizontal; balance the load
.
•
Angle β must be between 0° and 45° as shown below.
