About this document
Seatrax Kingpost Crane Maintenance Guide by Irwan Diharjo is a document available to read on EtoBox.
The document compares old roller bearing cranes to Seatrax kingpost marine cranes. Roller bearing cranes bolt a revolving superstructure onto a roller bearing subjected to load forces, risking separation if the bolts or bearing fail. Kingpost cranes have a fixed post with a revolving superstructure, eliminating bolts and ensuring the crane cannot separate from failures. Kingpost cranes also have easier and less expensive bearing maintenance than roller bearing cranes.
