Do not loop the top sling through the crane hook. The slings at any
one end of the spreader must match each other in length.
● Max. combined sling diameter on one side: 6.5 inches.
● Main pin dia. 7.4 inches. Please check bending radius (D/d)
● Rated at 400 tonnes up to 36ft (60° BSA).
See load table for SWL at longer spans.
● BSA (Base to Sling) angle α, 45° or more.
● End Units are rated at 200 tonnes WLL each
(400 tonnes combined capacity)
● Bolt torque: 184 Pound-foot. Spanner size 36mm.
● Recommended additional equipment: Torque Wrench,
Podger Spanner and a Ring Spanner
● Minimum BSA Angle of the bottom slings is 45°
● The maximum in plane angle of the bottom slings is 6˚ STV. If this
needs to be exceeded please contact Modulift prior to the lift.
● When specifying slings, use an additional factor of 1.2 to
allow for uneven sling lengths. Refer to Modulift if in doubt.

Table 1 – Component List
The Modulift Trunnion Spreader is modular in length. Every Trunnion spreader consists of two End Units and
intermediate struts that can be bolted into the assembly to achieve dierent spans. The Trunnion End Unit is
also compatible with existing Modulift struts. The TRUN MOD 250/400 has an assembled span ranging from
6 ft to 68 ft in 1 ft increments.

Do’s & Don’ts
● Do ensure to load the spreader through the main trunnion
pin only. i.e. adhere to Fig. 1.
● Do keep the loaded spreader clear of obstacles
– any contact could cause beam failure.
● Do ensure correct use of appropriate top slings, do not twist
any slings unnecessarily.
● Do not hang any load from the spreader tube or anges.
● Do not exceed stated SWL for that particular span
– adhere to Table 2.
● Do not rig the lower slings less than 45 degrees BSA.
● When moving or positioning long struts or assemblies use
tag lines to control movement.
● Individual components can be heavy and extreme care must
be taken if manual handling.
Recommended top sling types:
Textile slings, cable laid wire rope slings or grommets.
Slings must have soft eyes. Always ensure clearance between
the sling and end unit.
Note: Lengthening the slings can give greater clearance.
Refer to Modulift supplier if in doubt.
Assembly Procedure
Please refer to separate assembly and setup
procedure for more information.
WARNING!
TRUN MOD 250/400 US SEP 2015
● The rigger must ensure that there is a clearance between
the sling end tting and the end unit as shown above.
● Max number of struts allowed in spreader assembly: 6.
● Assemble longer struts in the centre of the spreader
conguration.
● Sling angle is crucial to safe use of spreader.

1. Firstly lay out the 4 top slings and connect them
all to the crane hook.
3. Ensure that the sling eyes for the top slings are
pushed in tight to the side cheeks of the beam, this
will leave room for the bottom sling eyes.
5. The bottom slings which are furthest away
from the spreader will need to be pulled across
the other pair of slings to help the eyes line up
with the trunnion.
7. When disassembling the beam, the lower slings
should be pulled inwards parallel to the spreader,
this will ensure that the eyes can be removed easily.
2. Then slew to one end of the beam and connect
a pair of slings, before repeating the process at the
other end.
4. Lay out the bottom slings and then lift the
spreader and put it down in the middle with a pair
of slings each side.
6. Do not forget to connect the safety chains on
both end units before lifting the beam out of reach.
8. Ensure that the Do’s and Don’ts of the user
instructions are followed to ensure a safe lift.
