Upon arrival we noticed the structural engineer placed a shore on the floor. The total weight our 25, 000 pound forklift and 15, 000 pound fans would overwhelm and crowd the shoring structure. Instead, we pivoted towards a gantry strategy.
Between the Project Manager and Foreperson Supervisor, we devised a plan with the new variables in mind. The team used forklifts to transport the fan from storage to the designated room. From there, the fan was placed on dollies and pushed towards the pitfall.
The fans were rigged one-by-one to the gantry and lowered into the pit. The fans were a dynamic load and the center of gravity of the fan was off-set. The fans had to be lowered horizontally, one leg at a time.
