This feature of the Xrosswater floating walkway is a visual indicator that the anchor chains or cable are enduring. When the load on the anchor chains has exceeded a set level, the indicator detaches, notifying that adjustments are required. Anchor load indicators have the benefit of keeping records of anchor adjustments. With this data, operators can pinpoint unsecured anchors.
Xrosswater works with a number of suppliers and engineering firms
Laminated material overlaid with a phenol film or with UV-resistant film on both the sides. The wear side has a rough wire mesh pattern (W); the reverse side normally is smooth (F), although it can have wire mesh pattern, too (grade W/W).The rough wire mesh overlay withstands hard wear and it can be used for many different floor-paneling purposes.
Vehicle floors, pedestrian bridges, storage and factory floors, storage shelves, loading platforms, ship decks, pier surfaces. In general - applications where high wear resistance and/or good anti-slip properties are required.
The wire mesh surface has high wear resistance and anti-slip properties, surface is weather and waterproof, resists to commonly used chemicals. Environmentally friendly.
Laminate glued with waterproof phenol formaldehyde resin adhesive. Bonding is resistant to weather and boiling water. It meets requirements of the following standards:
EN 314 / 3 rd class; BS 1203 / H4 (previously WBP); DIN 68705 Part 3 / type BFU 100.
The panels are overlaid with a phenol film with a wire mesh pattern imprinted during hot pressing process. The unit weight of the film is 220g/m2. On special request, panels can be overlaid with wear resistant phenol film or/and multi-layer phenol film. Large Mesh (grade WL) - 2.5 mesh per 1cm, Small Mesh (grade WS) - 4.5 mesh per 1cm.
The overlaying surface is highly resistant to abrasive wear and it does not crack. It is also resistant to weather and moisture as well as commonly used chemicals. The wire mesh patterned surface provides high anti-slip properties. The panels can be machined. During machining extra hard cutting tools are recommended.
Abrasion resistance according to the Taber
Edges of the panels are matched with the face against absorption of moisture with acrylic paint and all edges are clamped in the Xrosswater Aluminium frame.
Certified to the requirements of ISO 9001 by Bureau Veritas Quality International, UKAS,
The concave meniscus surface on the top of Xrosswater grating provides superior slip resistant footing in most environment including wet or oily conditions.
Xrosswater deck material meets the anti-slip class in accordance with DIN 51130-R11. The CoF is at the mid to high end of 0.40's and thus borders onto the R12 classification.
German Ramp Test: R Numbers
R-Numbers DIN 51130
The following table show the level of slip risk associate with different R-Numbers as defined by the German Ramp Test and DIN 51330. If a floor is likely to be wet then R13 is the best. Only R12 or R13 should be considered for swimming pool surrounds or changing areas. R11 may be suitable for transitional areas of floor i.e. floors that can become wet despite efforts to keep it dry such as the entrance to a shopping mall or dry changing room floor. R10 may be suitable for areas of floor that can normally be kept dry and R9, the lowest value should only be considered for floors that can never become wet or have very few people using them.
information is provided as an aid in
determining proper anchors and installation methods. However, all sites are
different. Use the proper site and soil/tailings
assessment to determine the anchoring technique to use.
The anchors used with the Xrosswater floating walkway system are critical components to the Xrosswater installation. When managed correctly, they will ensure long lasting problem free use of the floating walkway.
1) Soil Type
The following information is provided as an aid in determing the proper anchors and installation methods. However, all sites are different and correct site assessment and soil / tailings determinations is required to determine what type and what quantity of anchors are required.
2) Settling Density
Most Tailings deposit settle differently. It is important to determine what is the normal percentage of water to tailings that is deposited, at what rate the tailings deposit settles, and if the settled tailing has any compounding characteristics that would support and increase the holding load of the anchor. This information is significant depending upon the required load the anchors will be required to sustain and the desired lifespan of the platform or walkway.
3) Depth of Tailings
With the soil type and anchor type selected, determination of what is the appropriate depth below the surface at which an anchor can obtain a respectable hold is required. This information can be obtained through proof testing at numerous locations along the proposed walkway position.
4) Weather conditions
In addition to the soil type and depth, it is also important to know the weather conditions at the site, such as maximum winds, directions and icing that may collect on the water. Soil conditions can soften or change markedly with heavy rains. Since there can be variations in the precise soil condition at a site, you may want to purchase two or more types of anchor sizes for the installation of the floating walkway, and choose the appropriate anchor once you have begun installation.
5) PH Levels
Understanding the present or the future PH level of the water is required to ensure that the correct chain type and linkage pieces are selected. Should there be a long distant between the anchor and the walkway, in certain circumstances, wire rope can be utilized and even at times certain fiber ropes can suffice.
6) Chain Web Anchors
Chain web anchors is a configuration of chains that are linked together to offer a web network that is reliant upon shared anchoring points to maintain the walkway’s position. Often used in locations with tidal movements and / or where anchoring can be difficult due to steep underwater slopes, or in water reservoirs where water level can drop and increase considerably. Such anchoring configurations can require multiple types of anchor load points and ballast not normally required on Tailings Dam
7) Screw-In Anchors
Screw-in anchors are recommended for softer soil types, Classes 5-7. They do not work well in rocky soils. The screw-in anchor is a hot-dip galvanized steel bar with an eye on one end for attaching the guy wires or chain and a variable diameter screw at the bottom depending upon the soil conditions. These are standard anchors used in the utility industry.
Screw-in anchors are usually installed by two people rotating a log bar threaded through the eye, but may also be installed with a power drive machine. The large diameter anchor may be difficult to install, so it may be more practical to install two medium size anchors at certain soil type locations.
