Marine
The marine and naval sectors require cranes and machinery that can adapt to every different type of vessel and do not deteriorate from salt water. Flexibility, resistance and performance are crucial factors. These are cranes from the light-, medium-, and heavy-duty ranges that are suitable for all kinds of handling operations in ports and shipyards.
Special base
Cranes equipped with a special base for easy installation in a fixed position on any type of vessel, featuring centralized controls and a distributor detached from the structure, protected against salt exposure.
Treatment of the marine series cranes consists of the following cycle: grade A Sa 2 ½ sandblasting (standard ISO 8501-1); organic epoxy zinc plating application (minimum thickness 70µm); intermediate layer with spray application of two coats of bi-component epoxy primer (thickness 100 µm) and a final dual layer of bi-component polyurethane glaze (thickness 70 µm) with average total thickness of the dry film on the entire packet of 240 µm. In this way a very high resistance to corrosion of up to 1500h in the salt fog testing is ensured according to the standard ASTM B117 (UNI ISO 9227).
Added protection
The main and secondary jack rods have a tempered chemical nickel plating (50 micron) and chrome plating (100 micron); the extension jack rods and rotation cylinders have a double chrome plating.
Protection is completed by application of “dinitrol” on hollow internal surfaces, and double nickel coating of stainless steel pins, screws and clamps.
