What's The Difference Spreader Beams vs Lifting Beams?
Spreader beams and
Lifting beams are some of the most common types of lifting devices; however the
difference is often misunderstood.
What is a Spreader Beam?
Spreader beams are a long beam that holds the legs of the lifting slings apart. They have two attachment points at both ends of the top side of the bar. These lugs attach to a lifting sling which can be made from chain, wire rope, round or web slings to evenly “spread” the weight of the load and connect to a crane, hoist, or other lifting machine. The underside of a spreader beam usually has two or more attachment points from which the load is lifted.
Pros for Spreader Beam:
- Convert
lifting loads into compressive forces into the bar and tensile forces in
the lifting slings
- Highly
effective in their use of material making them smaller and lighter (and
less expensive) than a similar lifting beam
- The load is
evenly distributed across the top 2 lifting points which reduces stress on
a single lifting point
- Ideal for
lifting wide, long loads
- Can help
control load tipping, sliding or bending
- Control the
sling angles reducing the chance of damaging the load
Cons for Spreader Beam:
- Require a lot
of headroom to accommodate the lifting slings above the beam
- Long or uneven
loads may require a tag line to control the load and reduce spinning
- Not ideal if
the load needs to be supported by multiple lifting points underneath the
beam
What is a Lifting Beam?
Lifting beams have a single centred lifting point on the top side of the
beam to connect to a crane, hoist or other lifting mechanism. There will be two
or more lifting points on the underside of the beam to attach the load to be
lifted. They can also be fabricated with adjustable bottom lifting points, at
fixed or variable increments. The addition of adjustable lifting points means
the beam can lift a wider range of sized loads. The heavy duty and rigid design
of a lifting beam makes them ideal to lift and support flexible loads.
Pros for Lifting Beams:
- They don’t
require much headroom
- Beams are
rigid and have a heavy design which is ideal for loads that are weak or
flexible and need support
- Lifting beams
can provide multiple lifting points underneath the beam and can be
designed with movable or fixed lifting points. This can make the beam
suitable for many different applications like off-centre loads, to control
inward crushing forces or utilise special load securement attachments.
Cons for Lifting Beams:
- More rigid and
use more material to make (which costs more $$)
- Heavier than
an equivalent spreader beam to counteract bending forces applied to the
beam
- May need a
tagline to control load movement
Our lifting specialist can
discuss your lifting application with you and help to determine the best type
of rigging equipment for the job. All Lifting custom manufactures all of our
lifting devices. All fabrication work is done in Australia, and all items are
supplied fully certified to Australian Standards with testing certification.
All Lifting can also organise regular inspections and testing and maintenance
of your lifting equipment, including load testing and re-certifying old
spreader bars or lifting beams.
