Modulift CMOD 50 User manual
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 different spans. The CMOD 50 has an assembled span ranging from 1m by
1m to 11m by 11m and all spans inbetween.
STRUT
• 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 ‘Lifting Operations and Lifting Equipment
Regulations 1998’ (LOLER)
• 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 ARE REFERRING TO
THE CORRECT TABLE

MODULIFT UK LTD
• 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
First pick the span required for your frame (e.g. 2m x 5m) and the Sling
Angle (we recommend 30° STV 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
conrmationonyourSWLifrequired.SWLgivenintonnes.
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

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
ASSEMBLY PROCEDURE
1. Check the ID plates on each Modulift component to ensure
the correct size is used.
2. Lay out the Struts and Corner Units in the correct
conguration
3. Checkthatallangesareclearfromdebris,sandetc.
before connection
4. Bolt the components together* using bolts, nuts & washers
provided. Tighten the bolts to torque as shown overleaf
5. 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
6. Loop the bottom Shackles through the eyes of the drop
slings and connect to the bottom of the Corner Unit with the
Shackle pin
7. Attach the lower slings to the load to be lifted
8. The assembled Spreader Frame and lifting rig must be
thoroughly checked by a competent person prior to lifting
