ARA-BOOM™

Aramid Fiber Mid-Boom Pendants for Draglines

Mining is one of the most punishing environments on ropes and pendants. In order to transmit raw power into cubic yards moved, your entire rope system must be rugged, reliable and designed to fit your job. Union ARA-BOOM aramid fiber mid-boom pendants have demonstrated 10 to 15 times the life expectancy of wire rope or strand used as mid-boom pendants on Bucyrus/Marion style draglines due to their improved resistance to tension-tension fatigue.

When shipped, Union mid-boom assemblies include bend restrictors to protect the assemblies during installation. If you need to store the assemblies, they require no special care and will not deteriorate, but we recommend that they be protected from the weather and rodents.

At Union, our quality processes ensure the highest quality product by controlling the product design, inspecting all raw materials, monitoring key elements of the manufacturing process, and conducting final product testing and inspection.

ARA-BOOM™ Aramid Fiber Mid-Boom Pendants increase service life on draglines

ARA-BOOM mid-boom pendants are being used on draglines across the world:

• In coal mines and phosphate mines

• In Australia, China and across the United States (Texas, Florida, North Dakota, New Mexico, Colorado, Wyoming)

• 10-15 times the service life of wire rope or strand

• Able to withstand tension-tension fatigue

• Maintenance-free

• Lighter, easier to handle during installation

• Can be tensioned to the same loads as the pendants being replaced

• Customized to your requirements
