Further issues to look into■ Class 3 cross section will require stiffeners
■ Foundations – Need to be far enough away from shaft – This increases the lever arm and greatly increases the
moment generated– Larger cross section needed

Conclusion■ Based on calculations the crane itself seems feasible ■ Similar capacity cranes have been built before■ The concrete plug is not expected to be a problem■ Investigate further the hydraulic jacks for concrete plug and the
column foundations■ DLT manufactures appropriate stand-jackers
