Spreader beams are some of the most popular below the hook lifting devices in the material handling industry. Just like lifting beams, spreader beams are used to widen the available lifting points on rigged loads and keep lifting slings at a 90° angle relative to the horizon. Unlike lifting beams which convert vertical lifting forces into bending forces on the beam, spreader bars convert vertical lifting forces into compression forces on the beam. Spreader bars for lifting and rigging consist of a beam with two or more lifting lugs on the bottom that attach to lifting slings that attach to the load. How they differ from lifting beams is in their top attachment. Instead of a single centered bail that connects to a crane or hoist hook, spreader bars are suspended by a multi-leg sling that attaches to the bails on top of the spreader beam.

At Tri-State Rigging Equipment we specialize in providing custom designed and fabricated spreader bars for lifting and rigging. We can also provide you with any standard “off the shelf” spreader beam on the market. If you cannot find what you are looking for, or if you don’t know exactly what you need, call or email or sales team to speak with a below the hook product specialist.

Spreader Beam Advantages

Spreader beams excel at lifting extra wide and heavy-duty loads. Spreader beams convert lifting forces into pure compression forces and therefore do not have to be as rigid as lifting beams. This means that they require less material, and are, in general, typically smaller, lighter in weight and less expensive than lifting beams. The use of two lifting points on top of spreader beams distributes the weight of the load evenly and eliminates the challenges that come from putting stress on a single lifting attachment. This unique design reduces the chances of load tipping, sliding, or bending, and reduces the risk of crushing or damaging the load.

For irregular and off-balance loads, telescopic and adjustable spreader bars, allow riggers to not only adjust the angle of the top lifting sling, but also the length of the beam itself. Fixed and adjustable spreader bars are an ideal material handling solution for almost any rigging application.

Spreader Beam Disadvantages

The use of an overhead sling to attach spreader beams to a crane or hoist hook means that spreader beams require much more head room than their lifting beam counterparts. This prevents spreader beams from being used in low headroom lifting applications.

In addition, spreader beams are not ideal for lifting loads that must be supported throughout the length of the load. If a load requires this kind of extra support, a lifting beam is most likely better suited for the application.

Lastly, the use of a tag line may be required to reduce the risk of the load spinning and to safely control the load while it is being lifted.
