Modulift CMOD 34 User manual
User Instructions
The CMOD Spreader Frame is modular in span and every frame consists of 4 Corner Units,
with intermediate Struts that can be bolted into the assembly to achieve dierent spans.
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 - 2013’.
Never exceed stated SWL – Adhere to SWL in Table 2 for particular sling angle used.
The top sling length is critical to the safe use of the spreader – Ensure you refer to the correct table.

WARNING!
Assembly Procedure
Check the ID plates on each Modulift component to ensure the
correct size is used.
Lay out the Struts 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 bottom Shackles through the eyes of the drop slings and
connect to the bottom of the Corner Unit with the Shackle pin.
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.
Do’s & Don’ts
Do ensure that the frame is only loaded at the Corner Units
and they are all equally loaded.
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 undertake a lift without the correct use of
appropriate top slings.
Do not hang any loads from the Strut tube or anges.
Do not exceed the stated SWL for your span.
Do not rig the lower slings more than 6° from vertical.
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 allowed in assembly: 5 per side
Assemble longer Struts in the centre of the conguration
Sling angle is crucial to safe use of frame.
The top sling must be positioned centrally in the Shackle
pin to ensure even loading. Contact your Modulift supplier
for supply of loose spacers where required.
First pick the span required for your frame (e.g.
10ft x 16ft) and the Sling Angle (we recommend 60°
BSA where possible), then check the SWL 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 SWL 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
SWL (to ensure no overloads are applied). Please
contact Modulift for conrmation on your SWL if
required. SWL given in Metric Tons (Tonnes).
