Microfissure Chrome Plating
Through the electrolytic action, the cylinders stems are coated with several layers of chrome to obtain a thickness of 100 microns which guarantees resistance in saline fog up to 260 hours (in accordance with ASTM B537) and extreme surface hardness.
6. Cylinder rods with marine double chromium plating and Nikrom
For heavier applications, nickel and chrome are used for the surface treatment of the stems. Thanks to these elements the process guarantees at least 300 hours of resistance in saline fog (ASTM B537).
7. Support plate for winch on 2nd boom
8. Pins protected with Geomet plating.
9. Pipes and relevant fittings in stainless steel AISI 316L.
10. High Ozone and weather resistance hoses.
11. Hoses with galvanized fittings protected with heat shrunk shroud.
12. Other fittings galvanized and painted.
13. Bolts and screws are either in stainless steel or protected with Geomet plating
Many fixing components (screws and bolts) are protected from atmospheric agents and rust through a water-based liquid coating containing inorganic metals (zinc and aluminium), named Geomet. The process conforms to RoHS directive and guarantees resistance to oxidation in saline fog for over 500 hours. Thanks to this process, components are protected on all sides from corrosion and the presence of zinc and aluminium allows self regeneration of damaged areas at a microscopic level. All fixing components which must guarantee high mechanical resistance, are treated with Geomet 321, in that the absence of hydrogen avoids weakening, critical for applications in aggressive environments.
14. Marine painting cycle with cataphoresis or zinc primer (RAL 1014)
Cataphoresis is a surface treatment able to give crane steel components considerable corrosion resistance. It is an electrolytic process involving complete immersion of the piece: it allows uniform surface covering with the resin. All parts of the treated piece are covered, providing high protection against chemical agents and rust, reaching an oxidation resistance equivalent to 500 hours in saline fog. The process is completed with a coat of paint according to client’s needs.
All parts of the crane are further protected from rust by a 3-layer coat (organic zinc primer, intermediate epoxypolyamidic, polyacrylic varnish) for a total thickness of 270 microns. The main result is a crane which is always protected by a colour which lasts.

REMOTE CONTROL SCANRECO
Our cranes can be provided with high quality remote control systems, either available as cable remote or radio remote control systems.
The control valve block is supplied with stand-alone controls for free installation close to the crane.
CONTROLS ON PLATFORM WITH SEAT
Column side crane controls are available on some of our models. For these cranes we propose the continuous slewing system.
In case of harsh environmental conditions, a cabin with crane’s controls inside is available. There are many options to equip the cabin (air conditioned, heaters, external protection, etc.).
Installation of different types of winch, offering lifting capabilities and speeds according to client and Classification Societies requirements. Effer can provide cargo winch, man riding winch, and special winch functions such as CT, PHC and AHC.
All our models can be fitted with Hydraulic Power Packs engineered to withstand the most aggressive marine environments and can be equipped with a variety of accessories, including oil heaters, oil coolers, pump-in load sensing execution.
HEAD PULLEY WITH MULTIPLE LINES
Each application requires different solutions to lift loads. We supply the winch kit with different types of pulleys at the end of the boom according to our client’s real needs.
LOAD CELL AND DISPLAY
A shackle with load cell and transmitter is an important option available upon request.
The value of the load is directly displayed both on remote control display and electric
console on the station.
