The FANCY FENCE gate is a patent-protected Polish invention. The use of standard components that are commonly associated with sliding gates allows this unique solution to be extremely simple and reliable.
Principle of operation
Precast reinforced concrete vault. The gate span and drive mechanism are located in a prefabricated reinforced concrete vault in the ground. The way that this vault has been produced, as well as the grade of concrete used, guarantee that it is 100% sealed and that it is impossible for ground water to get into the vault. From the top, the precast vault is covered by removable covers with holes cut out to match the shape and arrangement of span elements that will pass through these holes. The central cover has an additional service opening that enables easy access to the drive for maintenance purposes or for emergency opening or closing of the gate.Â
Counterweight and drive system. The span of the gate is connected to large counterweights through a system of cables and pulleys, where the weight of the counterweights is equal to the weight of the span. This design enables the use of conventional and easily available low power electric drives, which guarantees reliability, ease of operation and maintenance of the entire drive system.
Moving mechanism.Â The complete unweighting of the gate span on the one hand makes it possible to use extremely low power electric drives. On the other hand, it makes it necessary to stabilize the span vertically with guide rails and wheels, as is the case with sliding gate systems. Proven sub-assemblies were used for this, however in the vertical plane rather than horizontally. All of the metal components that make up the gate mechanism are made from steel that has been protected against the elements by the application of a number of protective coatings.
Principles of installation
Prior to the installation of the gate, the parameters of the ground and the possibility of encountering buried infrastructure or tree roots needs to investigated. Prior to installation a thorough verification of the actual installation conditions is required. If necessary, appropriate actions need to be carried out, e.g. partial or complete replacement of the soil, the use of additional reinforcement of land or a slight change in the location of the gate in order to avoid any potential issues. The actual installation of a complete Â FANCY FENCE system (driveway gate, walkway gate and fence) takes less than 24 hours.Â
What happens when water enters into the gate system?Â
First of all, it should be emphasized that water is nothing dangerous for this type of gate. All components are designed for outdoor installation, also for extreme weather conditions. Due to the complete waterproof sealing of the precast concrete vault, the only way for water to get inside the vault is through the holes in the covers of the vault. In the event that a large quantity of water gets into the vault, the pump located at the bottom of the vault will automatically pump out the excess water.
How does the gate operate in the winter?
Neither the cold nor the snow are obstacles to the proper functioning of the gate. Firstly, because it is assembled from standard components designed to operate in all weather conditions. These elements, such as the drive, in the case of sliding gates are directly exposed to the snow and cold outside temperatures. FANCY FENCE has these components hidden beneath covers, under the ground at a zone with a relatively stable temperature of about 0-5Â°C (depending on geographical location). It is further important to remember that 99% of the time the gate remains closed, with the span protruding above ground level. When the gate is opened, any ice that may have formed or accumulated around the span elements cracks under the weight of the span descending into the vault.
What happens when there is a power outage?
In the event of a power failure there are two possible solutions: emergency manual opening or closing of the gate, which can be done with the use of a handle, through the service opening, located in the centre cover. The fact that the span-counterweight system has a neutral weight differential, allows for it to be lifted or lowered effortlessly even by children. The second option is to purchase the optional integrated battery that allows for 5 to 10 opening and closing cycles without charging.
Is the gate safe?
Retractable gates that descend into the ground are fitted with identical sensor systems as those used for sliding gates. They are aesthetically mounted on the outer components of the fence on both sides of the gate. At the instance that the light beam is broken by any object, the safety system immediately stops the movement of the gate.
What happens in the event of failure of the assemblies of the gate?
Due to the use of exactly the same components as are used for sliding gates, there is no reason for retractable gates to be less reliable than sliding gates. As with other gates, the most common potential problems during use are with the drive system. This is why, it is easily accessible through the central cover. Any other mechanical breakdowns require the removal of the other covers, and this enables the service technician to have easy access to all of the components of the gate.
