Lifting; Storage - Samson 3275 Mounting And Operating Instructions

− Protect the actuator against moisture and
dirt.
− Observe permissible temperatures (see
section 3.3).
4.2.2

Lifting

To mount a large actuator, use lifting equip-
ment (e.g. crane or forklift) to lift it.
Lifting instructions
− Secure slings against slipping.
− Make sure the slings can be removed
from the actuator once it has been
mounted onto the valve.
− Prevent the actuator from tilting or tip-
ping.
− Do not leave loads suspended when in-
terrupting work for longer periods of
time.
− Make sure that the additional sling be-
tween the lifting eyelet and rigging
equipment (hook, shackle etc.) does not
bear any load when lifting valves. The
sling only protects the control valve from
tilting while being lifted. Before lifting the
control valve, tighten the sling. The slings
attached to the valve body must bear the
entire load (see Fig. 4).
Lifting the actuator (without valve)
NOTICE
!
Risk of actuator damage due to incorrectly
attached slings.
The lifting eyelets on the cover are intended
for mounting and removing the actuator as
well as lifting the actuator without valve. Do
EB 8314 EN
Measures for preparation
not lift the entire control valve assembly us-
ing the lifting eyelets.
1. Attach a sling to the lifting eyelets of the
actuator and to the rigging equipment
(e.g. hook) of the crane or forklift (see
Fig. 4).
2. Carefully lift the actuator. Check whether
the lifting equipment and accessories can
bear the weight.
3. Move the actuator at an even pace to the
mounting site.
4. Mount the actuator to the valve. See sec-
tion 5.1.
5. Remove slings after mounting.
Tip
We recommend using a hook with safety
latch (see Fig. 4). The safety latch prevents
the slings from slipping during lifting and
transporting.

instructions on how to lift a control valve.

4.3 Storage

NOTICE
!
Risk of actuator damage due to improper
storage.
− Observe storage instructions.
− Avoid long storage times.
− Contact SAMSON in case of different stor-
age conditions or long storage periods.
