Since the ancient Greeks invented the first construction crane around the year 900 B.C., a certain amount of risk has always been inherent in the use of a hook to lift heavy objects. Engineered Rigging has created what it terms "a revolutionary game changer" with its patent-pending Pipe Modular Lift System (PMLS). The PMLS eliminates the hazards of suspended loads by employing a platform that mechanically raises and lowers heavy cargo via a system of structural elements. To maximize safety, the self-locking PMLS provides synchronized lifting and positive mechanical engagement of the cargo and the platform, and its performance is not affected by unbalanced loads.
