Car deck for Ro-Ro ships (without integrated lifting system)
Navalimpianti
In the design and construction of car decks, Navalimpianti targets are low weight and system flexibility. For this purpose, two different lines of product have been developed: hoistable and folding type car decks. In both case, car decks may be completed by access ramps.
Car deck travel is performed by means of jigger winch that may be positioned inside the panels structure, under the fixed deck or at ship side, and platforms are suspended by means of hangers, usually pre-stressed wire ropes. During the vertical movement, panels are guided into strong tracks in order to reduce the torsion stress on structures.
Each single car deck can be locked at different working level by means of hydraulic locking devices and/or mechanical supports.
Operation of car decks system is assured via hydraulic or electro-hydraulic power and control systems originally designed and manufactured by Navalimpianti.
For fast ferries application light alloy may be used to reduce the structural weight.
