With clear span beneath the structure and height of up to 6 meters, excavation equipment such as midsize diggers and large bobcats can be used to offer time efficiencies and head room for specialist equipment, without the danger of collapsing wood stacking or stys. Further benefits of the Atlas 5 HL system is the ability to re-arrange the lifting towers and re-configure the beams to suit each dwelling differently. Most lifts can be undertaken without the complete destruction and excavation of the surrounding section, or even the removal or demolition of internal fittings, as the heavy duty lifting towers and beams are designed for heavy dwellings up to 3 stories. Once a house is lifted, those working onsite are able to move freely beneath it in order to demolish or build without any major obstacles in the way. When using the Atlas HLS 5.0, the house is always on structure and never becomes a live load on timber stys or cantilevered. For added security, safety chains are sometimes used to connect end tower pairs to each other and the Primary Lifting Beams.
