Modular Lift TowerModular Lift Tower

The Barnhart Modular Lift Tower (MLT) is a custom-designed alternate lifting method that is a reinvention of heavy lift technology. The pin connected nodal design offers ease of erection without any bolted connection. The innovative design and use of advanced computer modeling technology has produced a tower system that is stable to 250' (75m) without guy wires, improving erection time and reducing site impact. The MLT may be configured to meet the site-specific needs of the project, including such features as lifting and tailing the vessel as shown in this project. Other features include:

  • Capacities to 1,600 tons with strand jacks
  • Capacities to 500 tons with Barnhart self-contained hoist modules
  • Containerized shipping for international and intermodal domestic shipping
  • Erected in less time than most heavy lift cranes
  • Ground loading normally 50% of typical crane lifts
  • Erected using normal site craft labor and construction equipment
  • Tailing operations completed with cranes or alternate methods
  • Each configuration is fully modeled using FEA based programs
  • Designed in consideration of local wind loads
  • Seismic design analysis available for specific geographic conditions
