CMOD 6: 6-Point Frame Specication
Rated at a maximum of 8 tonnes WLL.
Please see Table 2 for WLL at specic spans.
‘Base to sling’ angle, α, 45 degrees or more.
Corner Units and T-Pieces rated at 2 tonnes
WLL each (8 tonnes combined capacity).
Bolt tightening torque: 44 Pound Foot.
Spanner size required: 17mm.

WARNING!
Personnel using this system should be
suitably trained, competent and have a clear
understanding of Safe Slinging procedures.
The use of Modulift equipment must be in
accordance with the procedures laid down in
ASME B30.20 - 2018.
Never exceed stated WLL – Adhere to WLL in
Table 2 for particular sling angle used.
The top sling length is critical to the safe use
of the frame – ensure you refer to the correct
table.
Do not under any circumstances hang load(s)
from the tube or anges – the Spreader Frame is
designed for compression – not bending.
Ensure that the top Shackle contacts the bow of
the corner plate‘bow-to-bow’.
The components in the frame will be marked as
ASME ‘Category B’, however the frame is modular
and some arrangements may be‘Category A’
due to this please contact Modulift prior to any
‘Category B’ application (e.g. Oshore).
Max number of Struts: 5 per side on the span
without T-Piece, 8 per side on span with
T-Piece.
All Corner Units and T-Pieces must be
connected to crane hook using top slings,
and to the load using bottom slings.
All slings must be correctly loaded i.e. no
sling (top or bottom) to be slack at any point
during lift.
Sling angle is crucial to the safe use of
the frame.
The top sling/turnbuckle must be positioned
centrally in the Shackle pin to ensure even
loading. Contact your Modulift supplier for
supply of loose spacers where required.
T-Pieces must be located opposite each other
and must connect to struts.
Table 2 – Load v Span
First pick the span required for your frame (e.g.
34” x82”) and the Sling Angle (we recommend 60°
BSA where possible), then check the WLL via the
appropriate table. Read the table by locating the
lower span on the y axis of the chart and the larger
on the x. The cell which you are referred to, will
indicate the WLL for your chosen span. If your exact
span is not noted in the table, then please round up
or down to the values that will give you the lowest
WLL (to ensure no overloads are applied). Please
contact Modulift for conrmation on your WLL if
required. WLL given in metric tons (tonnes).

Do’s & Don’ts
Do ensure enough clearance between frame and
the load to prevent the load hitting the frame.
Any collision could cause failure of the frame.
Do not exceed the individual WLL of any Corner
Unit or T-Piece taking into account CoG osets.
The frame is designed to lift a single solid item
using 6 points of the frame.
To ensure no slings are slack, use turnbuckles on
the central top slings, use matching top slings
for the corners, and matching bottom slings
all round. For oset CoGs, or where loads have
dierent spans to the frame, more turnbuckles
will be required for the top and/or bottom slings.
Turnbuckles must be adjusted until all slings
are in tension. Contact Modulift for advice if
in doubt.
Ensure that Fig.2 is checked and followed.
When connecting Corner Units directly to
T Pieces i.e. no struts between these
components, assembly may be dicult due to
fabrication tolerances. Please contact Modulift
for advice.
Do not hang any loads from the Strut tube
or anges.
Do not exceed the stated WLL for your span.
Do not rig the lower slings more than 6°
from vertical.
Assembly Procedure
Check the ID plates on each Modulift
component to ensure the correct size is used.
Lay out the Struts, T-Pieces and Corner Units in
the correct conguration.
Check all anges are clear from debris, sand etc.
before connection.
Bolt the components together* using bolts, nuts
& washers provided. Tighten the bolts to torque
as shown overleaf.
Loop the top Shackles through the bows of the
Corner Units so they contact ‘bow-to-bow’. The
eye of the top slings can then be passed through
the jaws of the Shackles and the pins replaced.
Loop the top Shackles through the remaining
top slings and connect Shackles to the top of
the T-Pieces.
Loop the bottom Shackles through the eyes of
the drop slings and connect to the bottom of the
Corner Units and T-Pieces with the Shackle pins.
Attach the lower slings to the load to be lifted.
The assembled Spreader Frame and lifting rig
must be thoroughly checked by a competent
person prior to lifting.
*The use of a Podger Spanner will aid in
assembly by helping to align the bolt holes by
forcing it through.
