In the past few years there has been a noticeably growing popluarity of articulated arm systems for gate motors. Most reputable manufacturers offer several different types of this solution. By which qualities is this system characterized? In which cases is this solution necessary? Is it right for your gate?
Case no. 1 – an outward opening gate
The biggest advantage of articulated arm systems is their flexibility, which allows for installation in otherwise unavailable places. They work best with swing gates which open outwards. When one intends to park a car on a short driveway, an outward opening gate becomes a necessity.
Case no. 2 – wide pillars
If the system is to be installed on a wide pillar (over 20cm in width), an installation of a traditional motor may be impossible. An articulated arm system is the only possible solution in that case.
Case no. 3 – narrow pillars
Some manufacturers (such as CAME, NICE, BFT) offer models of articulated arm motors designed specifically for installation on narrow pillars (up to 8 cm in width – FLEX CAM or up to 10cm in width – Nice WALKY). However, these automation systems are not designed for intensive work . It is the solution of choice for small and fragile gates.
Case no. 4 – the gate is too close to a narrow corner
An articulated arm can be installed in very tight corners, where the distance between the motor and the wall is extremely short. For example, the NICE model – Walky requires a minimum distance of only 8cm . The diagram below presents the correct way to measure this minimal distance.
Case no. 5 – gate mounted far from the motor
Another case, in which the articulated arm automation system is the only choice, is the situation in which the hinge is located far from the motor (distance D). While the maximum D of tube motor is more or less 15-20cm (exception: Nice TOONA, D = 28cm), the average maximum D of articulated arm systems is about 20-35cm. For instance, NICE HYKE allows for D of up to 40cm and NICE HYPPO boasts an extending arm allowing for D of up to 45cm. The outline below presents the correct way to measure the D distance.
Among the various advantages of articulated arm units the simplicity of installation is worth mentioning. A lot of motors (e.g. most Nice motors) allow for an installation without welding. The aesthetically pleasing, unflashy and inconspicuous appearance is also a benefit of the articulated arm system. Many models are also equipped with an integrated control system. Not only do they save space but also hardly affect the way that gate presents itself.
