Hoisting Equipment (Cranes)

An important factor that influences the selection of the formwork system is the availability of crane time. Crane time is defined as the time in which the crane is engaged in raising and lowering construction materials and tools. In congested site conditions where installing more than one crane is difficult, the limited crane time available for formwork erection to meet the project comple­tion date becomes a major factor that may lead the formwork de­signer to choose crane-independent systems such as self-raising formwork or slipform alternatives (which requires no crane time).
