Hydraulic cylinders used on shipboard machinery or in shipyards must endure the toughest of conditions, including hot and cold temperature extremes, exposure to salt water, driving rain, ice, as well as dirt and many other forms of contamination.
That is an extremely abusive environment for hydraulic actuators. Cylinders used under these conditions must be designed and manufactured with these well in mind if they are to survive and work reliably.
In addition, many hydraulic cylinders used on ships and harbour cranes are very large-bore and very long-stroke. Their large size makes frequent repair or replacement simply out of the question. Other marine cylinders are mounted in a ships machinery that is very difficult to reach. All these factors makes reliability a primary concern for marine cylinders.
Gidrolast has a great deal of experience in building marine-grade hydraulic cylinders that thrive under those trying conditions.
Gidrolast marine-grade cylinders are constructed with chrome plated rods that are rated to withstand a ****1,**0 hour salt spray test. Marine cylinder bodies are coated with epoxy paint to maximise corrosion resistance.
For more difficult applications, Gidrolast can build marine cylinders with stainless steel piston rods for additional corrosion resistance. For maximum corrosion protection, we can even manufacture cylinders with all stainless steel construction.
We have built both standard rod cylinders and multistage telescopic cylinders for marine use. Harbour crane applications including luffing cranes, container loaders, swing cylinders, and more. Shipboard applications include shipboard luffer cranes, hatch cover cylinders, ramp cylinders, gate cylinders, steering actuators, and more.
The Gidrolast large-bore, long-stroke rod cylinder shown above operates as a Shipboard Crane Cylinder.
The Gidrolast marine cylinders shown above are coated with white epoxy paint to resist corrosion. This will ensure a long trouble-free service life under harsh marine conditions. These particular actuators operate as Gate Cylinders.
