Offshore crane sheaves
Certex has wide experience and competence in design and delivery of sheaves to offshore cranes in all sizes. The sheaves are delivered fully assembled with bearings with painting according to Norsok M501 systems.
Our offshore crane sheaves are designed to handle active heaveCompensated loads (AHC) and large fleet angles. Our competence and experience results in an optimized sheave fully suited for its purpose. If required, our the grooves of our sheaves can be induction hardened to achieve a hardness of up to 500 HB.
Our sheaves are made from ductile cast iron or machined from steel plate, both production methods that don’t require any class product certificates.
