Overhead Cranes

Tennessee Sling Center / Progressive Crane Overhead Cranes

Tennessee Sling Center works with Progressive Crane (A Mazzella Company) to manufacture world-class overhead cranes. We engineer and build custom solutions ranging from light-duty economical cranes to large-capacity high-duty cycle cranes with welded plate-box girders.

Our work is done in full compliance with CMAA, NEC, OSHA and ASME standards. We have extensive electrical capability, as well as AWS certified welders.

  • In-House Engineering

    We provide in-house engineering and can also furnish PE (Professional Engineer) stamped drawings and calculations. All drawings are done in SolidWorks—this reduces calculation time and increases productivity, which saves our customers money.

    Also, being electronic, the calculations and drawings may be e-mailed to further save time. This is an ideal solution for companies with fabrication capabilities, but with no in-house engineering.

  • Crane Runways
    We believe it’s logical that the engineers who design your crane also design your runway structure. Our engineers utilize SolidWorks to create your runway designs, in strict accordance with CMAA, ANSI, Uniform Building Code, AISC and American Welding Institute standards and practices.
  • Fabricated Runways

    The same rugged quality that goes into our cranes is applied to our runway structures. In many cases, the same craftsmen and welders who fabricate your crane also produce your runway structure.

  • Install Runways

    A correctly installed runway structure ensures a smooth-running crane system. Our installers are runway experts with experience established over many years and hundreds of installations. They have developed unique skills and special tools to make installations quick and easy.

Engineered Products

Tennessee Sling Center Engineered Products

We have more than 60 years of field application experience and in-house manufacturing. This has earned us the reputation as a leader in the design and development of custom engineered below-the-hook lifting devices and lifting attachments for use with all types of cranes.

Our participation on the ASME B30.20 Subcommittee (that governs manufacturing, inspection, marking, testing, maintenance and operation of the below-the-hook lifting devices) sets us apart from our competition. On-staff engineering and our commitment to ISO 9001: 2008 guides us to continued success in quality products and processes.

Our products range from a common lift beam to an engineered special 150 lbs. engine line lifter to a 330 ton electric furnace lifter.

Repairs, Inspections & Recertification of Below-The-Hook Lifting Devices

We offer complete, in-house inspections and repairs of below-the-hook lifting devices. Certified Inspectors, along with our Engineering Department, perform detailed analysis. Repaired or rebuilt units provide significant cost savings. We also can provide FEA (Finite Element Analysis) reports and reverse engineering options on customers' lifting devices. Customers can send in a unit, enabling Engineering to measure and model the unit in SolidWorks and run FEA analysis that determines the safe working load.
