Rigging Package for Nine Air Handling Units – Aspen Aerogels

CUSTOMER CHALLENGE

Our mission, in collaboration with R.F. Knox Company and Turner Construction , was to transport oversized air handling units, each weighing 12,000 lbs and measuring 20 feet in length, into a facility with restricted access. The objective was to move these units through a precast opening, with the added constraint of completing the offloading and installation within a single day, due to third-party trucking considerations. 

Challenges included: 

1. Precise Handling Without Anchorage or Drilling: As the facility was constructed as a post-tension structure, traditional anchorage or drilling methods were not an option. This constraint required us to devise innovative solutions.
2. Second-Floor Placement: The location of the air handling units on the second floor presented a further challenge. The structural integrity of this floor couldn’t withstand the weight of a forklift, necessitating a different approach.
3. Limited Headroom: Within the facility, there was minimal headroom for stacking the units once inside, leaving less than a foot of clearance above the gantry.
