MGF-GN36-r2-04/22-AW
MGF 120 Series Underslung Lifting Beams are available in two lengths of 3.5m and 4.25m,
each beam has a WLL of 2000kg making a pair capable of lifting 4000kg.
One of the intended applications for this product is handling static caravans. A pair of
beams achieve weight category D in accordance with NCC Code of Practice 501.
The 3.5m beam (product ID 2.9135) is suitable for 10ft wide caravans.
The 4.25m beam (product ID 2.9142) is suitable for 12ft wide caravans.
The system is provided as a rigid beam (A) with two 3.25t safety bow shackles (B).
It is recommended that the Underslung Lifting Beams are used in combination with either
MGF F55 Spreader Frames or S80 Spreader Beams above the caravan to prevent any
crushing effects.

120 SERIES UNDERSLUNG LIFTING BEAM
120 SERIES UNDERSLUNG LIFTING BEAM - CARAVAN
HANDLING OVERVIEW
• Each beam has a WLL of 2,000kg
• 12ft caravans should be lifted with the 4.25m beams
• 10ft caravans should be lifted with the 3.50m beams
• Slings must be vertical [β] within 3° or less
• The designated caravan support points MUST be seated within the safe lift zone painted
yellow on the beam
• The caravan centre of gravity must be seated centrally on the beam to ensure a safe and
even lift, ensuring that lift points are not overloaded
• Prior to lifting, perform a test lift slightly above the ground to ensure that the load is
balanced
• Check the ID details on each component to ensure the correct lengths are used
• Connect suitable vertical slings (min. 1t WLL) to the lower shackles on either MGF
S80 Spreader Beams or F55 Spreader Frames, ensure lengths allow for clearance of
guttering etc.
• When using these beams with caravans position the Underslung Lifting Beams under
the caravan support points ensuring that they make contact within the ‘Safe Lift Zone’
• When using these lifting beams in other applications it is essential that the supports of
the item being lifted are within the ‘Safe Lift Zone’
• Connect the vertical slings to the 3.25t safety bow shackles [B] at each end of the lifting
beams

1. The beam has a WLL of 4,000kg when point loads are applied as long as the 1.5m
central span is not loaded.
2. The beam has a WLL of 3,000kg when point loads are concentrated to the 1.5m central
portion of the beam.
3. The beam has a WLL of 3,000kg when load is applied as a UDL (universally distributed
load) over a span from 0 to 1.50m.
4. The beam has a WLL of 3,500kg when load is applied as a UDL (universally distributed
load) over a span from 1.5m to 2.0m.
5. The beam has a WLL of 4,000kg when load is applied as a UDL (universally distributed
load) over a span from 2.0 to 4.86m.

BEAM INTRODUCTION
• Check the ID details on each component to ensure the correct lengths are used
• Connect end attachments [D] to 5.0m S80 strut [E] with 8no. M20 x 65, grade 8.8 HT
bolts, nuts and washers [F] at each end. Tighten all bolts to a minimum torque of
240Nm, 2 threads minimum must be visible beyond the nut. Bolts should be re-
tightened before every lifting operation
• Ensure that the handling points [G] on the S80 strut point sidewards leaving a clear
space on the top face for positioning the load
G
• Connect drop link [B] to end attachment [D] with bow shackle [A]
• Connect suitable vertical slings (min. 2t WLL) to upper shackle [C] and secure onto
drop link [B]
• Ensure that there is adequate clearance between the load being lifted and the vertical
slings to avoid snagging
• It is recommended that S80 spreader beams or F55 spreader frames are used above to
support the underslung lifting beams below
• Vertical slings must be vertical [β] within 3° or less
• The load must be rigid and secured in such a way that the underslung lifting beams
cannot slide apart or together when in use
• The load must be seated in such a way that it cannot cause the S80 to rotate about its
axis
• The centre of gravity must be seated centrally on the beam to ensure a safe and even
lift, ensuring that lift points are not overloaded
• Prior to lifting, perform a test lift slightly above the ground to ensure that the load is
balanced

S80 UNDERSLUNG LIFTING BEAM
It is the hirer’s responsibility to inspect the beams and all fittings prior to any lifting
operations being undertaken. Consult an MGF representative before lifting if there is any
doubt over the quality of the equipment or if you are unsure about any aspect of these rules.
Equipment to be used in accordance with MGF’s terms and conditions of hire.
All operations must be carried out to approved method statements and risk assessments.
PRE-LIFT CHECKS
Before lifting there are several checks which should be done:
Must ensure that the slings are not twisted or tangled
Confirm that correct lifting points are being used
Keep the loaded beams clear of obstacles – any contact could cause unsafe
release of load or beam failure
Ensure that the sling lengths and rating are suitable, and the beam does not tilt
Ensure that the centre of gravity of the caravan is positioned centrally on the
beams to ensure an even lift
Each component needs to be checked prior to each lift
Prior to first use of a new assembly, carry out a trial lift just above ground level to
ensure that straightness is maintained under its own self-weight
Ensure that the lifting beams cannot slip on the support points during the lift.
Clamps may be required
SAFE USE WARNINGS
Before operatives use the equipment, they should read and understand
these warnings:
• Do not exceed stated WLL for all of the components
• Do not rig the vertical slings more than 3 degrees from vertical.
• When moving or positioning use tag lines to control movement.
• Individual components can be heavy and care must be taken if manual handling.
• The equipment must be used in accordance with the procedures from ‘Lifting
Operations and Lifting Equipment Regulations 1998’ (LOLER).
• Operatives using this system should be suitably trained, competent and have a
clear understanding of Safe Slinging procedures.
• Never lift over or near people, ensure an exclusion zone is in place during any
lifting operations.
• Do not use on uneven ground or during high winds.
• All loads being lifted should be rigid and additional safety measures may be
required to prevent the beams from moving or twisting during the lift.
