When an estimate becomes a contract we commence the gathering of information for the designer. The survey is carried out to obtain accurate dimensions and the data is requested from the crane manufacturer. This typically consists of crane mass, wheel centers and wheel loads along with surge loading's and crane speeds. The crane dimensions are added to the arrangement drawings to ensure it fits the building as required.
Design is carried out in accordance with the following codes:
