Modular Lifting Beams

1. 9/7/2010
Alltec Modular Lifting Beams, patent pending,
were designed and manufactured in 2009 to
meet the needs within the petro‐chemical
industry to set modular components with ease.

Alltec’s modular system designs can be constructed to
lift larger loads over longer spans, The same method
of design and analysis will be used on all of Alltec’s
modular systems.
