Pipe Modular Lift System

Engineered Rigging’s patent-pending Pipe Modular Lift System (PMLS) eliminates the hazards of suspended loads. Different from all other heavy lifting systems, the PMLS employs a platform that mechanically raises and lowers heavy cargo via a system of vertical lift rods connected through gearboxes to electric motors. It is proudly engineered and manufactured with domestic materials in the U.S.A. This revolutionary vertical lift mechanism secures both the cargo and platform. It provides positive mechanical engagement 100% of the time and completely eliminates below-the-hook lifting. 

Special Features

In addition, the PMLS integrates seamlessly with multiple load handing systems such as a Self-Propelled Modular Trailer (SPMT), intermodal transport, etc. Additional advantages of the Pipe Modular Lift System include:

  • Faster Lift Times: 20 in. per minute. The PMLS is about twice as fast as comparable strand jack systems.
  • Improved Reliability: no failing cable drums or leaking hydraulics
  • Rapid Assembly: fully operational in just five days
  • Modular Design: customizable lift capacity and footprint
  • High Wind Tolerance: operates in 50-MPH winds, essential for keeping critical path projects on schedule
  • Easy to transport: ships in standard ground trailers

Patent-Pending Design

  • Free-standing, modular column assembly
  • Customizable lift capacity and height 
  • Configurable footprint (square, rectangular and round layouts)
  • High-capacity runway
  • Enclosed lift system protected from weather
  • Heavy-walled steel construction
  • Proudly made in the U.S.A.
