What Is a Spreader Beam?
Design, Uses and Key Differences
A technical guide to spreader beams, including how they work, when to use them, and how they compare to lifting beams.
A spreader beam is a below-the-hook lifting device used to distribute load across multiple lifting points. The beam is loaded primarily in compression, with top slings transferring force into the beam and bottom slings supporting the load. This improves load stability and reduces stress on both the load and lifting equipment.
Why Use a Spreader Beam?
Spreader beams are used where loads require multiple lifting points or where stability is critical during lifting operations.
They are particularly suited to long, flexible or structurally sensitive loads, where uneven lifting forces could cause distortion or instability.
By distributing the load across the beam, lifting forces are controlled and balanced, improving stability and overall lift safety.
Types of Spreader Beams
Fixed Spreader Beams
Used for lifting operations with a consistent span and load requirement. Simple, stable and suited to repetitive lifts.
Adjustable Spreader Beams
Allow the span to be altered to suit different load sizes. Useful where lifting requirements vary between operations.
Modular Spreader Beams
Designed for heavy and complex lifts. Modular systems can be configured to suit a wide range of spans and capacities.
Multisec modular spreader beams are engineered to:
- DNV-ST-0378
- BS EN 13155
- Eurocode 3
How a Spreader Beam Works
A spreader beam converts a single crane hook connection into a two-point or multi-point lift.
Top slings transfer the load into the beam, placing it in compression. Bottom slings connect the beam to the load, distributing the weight across multiple lifting points.
Sling angle is a key factor in performance. As sling angles increase, sling tension increases and the allowable working load is reduced
Spreader Beam Vs Lifting Beam
Spreader Beam
- Typically loaded in compression
- Uses top slings
- Suitable for longer spans
- Provides improved load distribution
Lifting Beam
- Primarily loaded in bending
- Single central lifting point
- Suitable for restricted headroom
- Simpler configuration
Selection depends on available headroom, load geometry and lifting requirements.
Key Benefits of Spreader Beams
Design Standards and Compliance
Spreader beams used in lifting operations must be designed, manufactured and verified to recognised industry standards. These standards define how lifting equipment is engineered, tested and certified to ensure safe operation.
Typical standards applied include:
DNV-ST-0378
Offshore and platform lifting appliances
BS EN 13155
Non-fixed load lifting attachments
Eurocode 3
Structural design of steel components
Proof load testing is carried out to verify structural integrity and confirm the beam performs as intended before being put into service.
Typical Applications
Spreader beams are widely used across heavy industries where load stability, control and safe force distribution are critical to lifting operations.
Offshore Wind
Used for lifting and positioning large components such as wind turbine sections, monopiles and offshore structures, where stability and load control are critical.
Ports & Shipping
Supporting the handling of containers, heavy cargo and marine equipment, ensuring loads are lifted evenly and safely during loading and unloading operations.
Construction
Supporting the handling of containers, heavy cargo and marine equipment, ensuring loads are lifted evenly and safely during loading and unloading operations.
Heavy Engineering
Applied in the handling and installation of large machinery and fabricated components, particularly where loads are complex or sensitive to uneven lifting forces.

Spreader Beam FAQs
A spreader beam is used to lift loads using multiple lifting points, improving stability and controlling how lifting forces are applied to the load.
A spreader beam is typically loaded in compression and uses top slings, while a lifting beam is primarily loaded in bending and uses a single lifting point.
See our Spreader Beams Vs Lifting Beams for more information.
Sling angles should be kept as low as possible. As sling angles increase, tension in the slings increases and the allowable working load is reduced.
Yes, when designed to standards such as DNV-ST-0378, spreader beams are suitable for offshore and heavy-duty lifting operations.
