High Risk Work Licence - Self-Erecting Tower Crane (CS) case studies
High Risk Work Licence - Self-Erecting Tower Crane (CS) · Put your knowledge to work in context.
The CS licence is an Australian high risk work licence class for operating self-erecting tower cranes - cranes that are transported as a unit or in sections and erected on site, often with their own jacking or folding mechanism, rather than being assembled by a separate climbing crew like a large hammerhead tower crane. It suits crane operators, hire-company staff, precast and tilt-up crews, and personnel in housing, commercial and industrial construction who need to erect, operate and dismantle these cranes lawfully. The High Risk Work Licence - Self-Erecting Tower Crane (CS) case studies are 5 cases and about 2,534 words.
