Brent Leisenring

Brent engineered and managed this complex heavy rigging operation as well as a diverse variety of numerous other customized rigging solutions during his time with Elgood Mayo Co. and Barnhart Crane and Rigging.

This operation was performed utilizing a variety of rigging tools including a deck barge for transporting the vessel from the overseas ship to a specially created docking location at the refinery shoreline; a 13-line Self Propelled Modular Transporter (SPMT) for moving the vessel off of the barge and through the refinery (on 104 tires); a 300-ton hydraulic gantry for repositioning the vessel on the SPMT at the erection site; a custom engineered self-tailing device for tailing the vessel on the SPMT during its rotation to a vertical position; a custom engineered Modular Lift Tower (MLT) with a 500-ton hoist and hydraulic slide system for lifting, rotating, moving into position, and lowering the vessel into final setting location. Two support cranes and two bulldozers were also utilized in preparing the site, erecting and dismantling the MLT. In addition to the barge docking site, a temporary railroad crossing was also constructed and dismantled to accommodate the SPMT.
