In order for the Manitowoc 4600 to drive up after arriving on the breakwater, the concrete crown section of 12 m was built up ahead. (00092020)

Description: Richards Bay Harbour/Natal/South Africa

Concrete Head on North Breakwater

The delivery of the Manitowoc 4600 was delayed considerably. Nevertheless, in order for the work to begin, the excavation material around the building site was provided with a dike, which was controlled day and night and repaired as appropriate with a wheel loader Caterpillar 988. A ground water drop also helped to keep the building site mostly dry. Therefore the north breakwater could be started in an ideal way. At a later date when the Manitowoc 4600 was then put into operation, it was impossible to adhere to this accuracy. The concrete head – 8.0 m wide and 2.40 m thick – consists of unreinforced concrete.
