Terminology Guide
Spreader Beam Vs Spreader Bar
The terms spreader beam and spreader bar are often used for similar lifting devices. This guide explains the terminology and why the actual load path and approved configuration matter more than the label.
By Multisec · Purchasing and engineering guidance
In lifting practice, “spreader beam” and “spreader bar” are often used interchangeably for a device that keeps lifting points apart and transfers load through a spreader member. The name alone does not define capacity or configuration. Always use the manufacturer identification, approved load data and instructions for the specific equipment.
Terminology
The Name Can Change. The Load Path Cannot.
“Spreader beam” is the term commonly used by Multisec for a below-the-hook member suspended by upper slings and used to keep lower lifting points apart. In some markets, project documents and supplier catalogues the same general type of device may be called a spreader bar.
Because terminology varies, engineers should not infer WLL, span or structural behaviour from the name alone. Identification plates, technical data, approved configurations and the manufacturer instructions define how a specific item is intended to be used.
| Term | What it usually describes | What must still be verified |
|---|---|---|
| Spreader beam | A spreader member suspended by upper slings, typically carrying significant compression | WLL, span, sling angle, component configuration and rigging |
| Spreader bar | Often an alternative name for a spreader-type lifting device | The same manufacturer and configuration data as above |
| Lifting beam | A beam commonly carrying significant bending load from a compact upper connection | Upper connection, lower pick points, WLL, span and headroom |
Selection
Use The Approved Configuration, Not A Generic Label
Two devices both described as “50 tonne spreader bars” can have very different allowable spans, top sling angles, end connections or component sets. Modular systems are particularly configuration-dependent because the same family of components can create several approved arrangements.
- Confirm the exact product or beam identification.
- Check WLL for the required span, not only the model headline capacity.
- Confirm the upper sling-angle convention used in the load data.
- Check end units, struts, drop links, shackles and lower rigging against the approved configuration.
- Use the current manufacturer instructions and technical data.
Spreader vs Lifting Beam
Do Not Confuse A Spreader Bar With A Lifting Beam
A spreader-type device usually uses upper slings connected towards the ends of the member, creating compression through the beam and requiring vertical space above it. A lifting beam often uses a more compact upper connection and carries bending through the beam, which can make it useful where headroom is restricted.
The correct route depends on load geometry, pick points, required span and available headroom. Where the terms in a lift plan are unclear, confirm the intended load path before specifying equipment.
Frequently Asked Questions
Common Questions
Is a spreader bar the same as a spreader beam?
The terms are often used interchangeably, especially across different regions and industries. The important point is the engineered configuration, load path, WLL, span, sling arrangement and approved manufacturer data.
Is a lifting beam the same as a spreader bar?
No. A lifting beam commonly carries significant bending load and may use a compact upper connection. A spreader device is typically suspended by top slings and works primarily through compression between the upper connection points.
Can I select a spreader bar by capacity alone?
No. WLL is only one input. Span, sling angles, lifting points, centre of gravity, rigging arrangement and the approved configuration must also be considered.
