All lifting arms on the Low Crane Modules are constructed from continuously welded high tensile steel (Grade 690 MPa). The low base is fabricated from medium tensile steel (Grade 350 MPa). The pins are mounted in replaceable lubricated glacier bearings.
The low crane modules can be stowed in a low folded position which is below the deck height. This means that:
The crane modules are designed to lift containers and must not be used to drag containers along the ground. The lifting chains must not be attached to the top of containers, or to non-standard length containers, as this imposes a sideways loading on the crane modules beyond their designed purpose. |
