OFFLOADING: The lifting equipment can be a boom truck, crane, or excavator and must be capable of lifting the weight of the pool from a vertical distance of between 22’ and 30’ from the ground to the attachment point above the center of the pool to the equipment that will allow the safe handling of the pool. These distances will depend upon the size of the pool, the type of trailer used to deliver the pool and the number of pools on the load. SwimUSA Fiberglass Pools requires that all pools be lifted with 4 lifting straps that are 30-feet in length and have a lifting capability of at least 1,500 pounds. Although our pools are built strong enough, all pools need to be lifted with a spreader bar, using a single piece of equipment. One end of each lifting strap is to be attached to the chains, which are located on the four corners of the pool, supported by the extra mounds of stitch mat. The other end of the lifting straps will be attached to the lifting bar that is located on the crane or lifting equipment. Any pool lifted with two machines, one at each end, will void the warranty.
