To make permanent moorings, to anchor floating docks or fish farms basins ,
etc... For equal weight, the helicoid anchors have a higher holding than any
other type of anchor. This type of anchoring can also be used for many
terrestrial applications, when it is necessary "to anchor" something
temporarily or definitively in a movable ground, soft ground - sand.
Advantages:
- For a cheap price, the holding of the helicoid anchors is highest.
- Made of hotdip galvanized steel, their lifespan is very long.
On the opposite of the temporary anchors, they do not dredge on the sea
bottoms, and do not require a great water height ratio for the mooring line .
They are thus respectful of the sea-beds ecology.
The "SKREW" anchor is made out of high strength steel . The rod is forged in
only one metal bar with an round eye fixation .
Fixing is carried out using a bar passed in this eye.

Special connection couplers are designed to allow sections to move independently under high-stress conditions, yet provide unified stability. Made with recycled material, the couplers are compounded to prevent fatigue problems. The composite coupler bolt and nut eliminate rusting in all water conditions

MOORING SYSTEMS - SPACING RODS
The system is designed and manufactured for the mooring of individual floating modules or jetties, when they have to be installed alongside the shore or the quay.
The device is made of pipes equipped with joint knees at both ends, for the fixation respectively to the quay and to the module.
Wind-braces, made of chains and eye-tensors fixed to the ends of the rods, prevent the floating module from horizontal movements.
All the steel components are hot dip galvanised; stainless steel screws and nuts.
Gangway with handrails normally provides the access to the jetty.

MOORING SYSTEMS - “UP AND DOWN” SELF-BEARING SLIDING DEVICE
The system is designed and manufactured for the installation of floating modules or jetties in places where both high water level variation occurs and the jetties are required to be installed alongside next to the quay.
The device is made of a corbel shaped electro-welded hot dip galvanised steel frame, equipped with polyamide rollers to ensure easy movement along a guide rail vertically fixed to the quay.
Floating modules are fixed on the sliding frame, thus allowing large upwards and downwards movements of the pontoon according to the water level variation.
Screws and nuts are made of stainless steel.

Derived from feedback from operators, Xrosswater® has utilised the most appropriate fastening components that offer the best performance under the most demanding conditions including a broad spectrum of temperatures, the effects of oils, chemical, cyanide, water, UV and the mechanical compositions of the material.
From the results of numerous tests, we identified the appropriate material to produce a hinge that would offer supreme performance whether the product is located in the open sea or in relatively calm inland waterways, reservoirs or rivers.
A connector that can flex multi-directional when under severe load and in doing so offers elasticity to the rigidity of a long walkway, yet maintaining a stable surface whilst loads are being transferred along the walkway.

The hydraulic powered Manta Ray anchor locker (LL-1M) pulls up on the anchor rod to set the anchor in the ground at the desired holding capacity. Portable and lightweight, the anchor locker consists of an open-center hydraulic cylinder with a control valve and a pressure gauge. Also included are welded base plates, an adapter setting bar, a tapered jaw set, and a metal storage box. The anchor locker is operated by the same hydraulic power source as the breaker.
