Description
The roller is of the horizontal axis type with a diameter such that it can hold up to 200 m of barrier type AR/70 and consists of:
- Frame
- Roller coil
- Retaining walls
- Hydraulic gear motor
FRAME
The base frame is made of AISI 304/316 steel bearing structure and 200×100 and 100×100 profiles of 5 mm thickness (alternatively it can be made of Marinized Aluminum), containing 200 m of floating barrier model AR/85 for about 560 kg. To better withstand the stresses resulting from the weight of the coil and those produced by the pulling phase, the supporting structure is reinforced with an additional center profile.
COIL
The winding reel consists of a central axis (drum Ø 450 mm approx.) A pair of side bulkheads (retaining sides) made of AISI 316 stainless steel and welded to 8 equally spaced AISI 304 spokes complete the rotating drum. The peripheral ring of the sidewalls will be made of AISI 316 tubular of 30 mm diameter and 2 mm thickness. The inner surface will be convex toward the center to facilitate barrier wrapping.
GALVANIZING & PAINTING
Painting will be full-cycle epoxyvinyl.
– Hot-dip galvanizing.
– Anchoring primer.
– Painting with two coats of epoxy for marine environment.
OPTIONAL
– Guide to facilitate the handling of the anti-pollution barrier.
– Local control panel for operation with IP55 protection.
– Acoustic/light motion detector.
– Entirely made of Marine Aluminum.
– Possibility of inserting the motorization inside the coil axis.
