Lifting Beam vs Spreader Beam
A sling alone isn’t always enough to safely move a load. Heavy or unbalanced lifts sometimes require more stability or capacity than a sling hitch can give. This is when riggers turn to below-the-hook lifting devices like lifting beams and spreader beams.
Beams increase the safety and efficiency of lifts where the size, shape, or weight of the load requires extra stability. They keep the load level with the ground, which helps prevent damage to the load and extends the service life of slings by reducing the chance of slings sliding off the load.
What below-the-hook device is best for my lift?
Standard and custom lifting devices are available for a wide variety of applications: some standard options are pipe hooks, C-hooks, coil lifters, pallet lifters, and beams.
Beams are used when the load requires more than one pick point for stability. When it comes to beams, there are two major below the hook devices: lifting beams and spreader beams.
Each has pros and cons that are valuable to know when deciding which is best for your particular application. The main difference between the two types of beams lies in the type of force that is put on each beam when under a load.
Lifting beams experience bending forces when under a load, while spreader beams experience compressive forces.
