built-in high-resolution magnetic pulse sensor, replacing the traditional mechanical limit switch and potentiometer. This means that the pointing accuracy can be stabilized within 0.1 degrees, and the user can flexibly set the software limit through the controller, without the need to climb the tower frequently for physical adjustmen
The internal transmission adopts steel gears that have been hardened and quenched. The gear accuracy is as high as 0.05mm. Compared with ordinary alloy materials, its anti-wear performance is increase...
With a static braking torque of up to 25000kg cm, it can lock up large dish antennas or Yagi antennas. When encountering 12 strong winds, the worm gear self-locking structure inside the rotator can prevent the antenna from shifting direction due to the “windmill effect” caused by the wind.
support 40 seconds to 100 seconds of rotation speed adjustment, and with automatic soft start and soft stop function. This design reduces the huge inertial impact on the antenna rod frame at the moment of rotation stop, and reduces the risk of metal fatigue of the tower.
The body adopts aluminum alloy die-casting with three-layer epoxy resin coating process, which meets the C5-M anti-corrosion standard. Even in coastal areas with severe salt spray corrosion or polar environment with huge temperature difference, the internal mechanical structure can be protected from oxidation and corrosion.
the base is provided with an independent sensor maintenance window. during routine inspection or sensor replacement, engineers do not need to remove the entire rotator weighing tens of kilograms from the high-altitude tower, thus greatly reducing the labor intensity and safety risks of later operation and maintenance.

in view of the communication integrator in the field site maintenance difficulties of the pain point, we solved the traditional limit switch is easy to cause ice or dust failure, resulting in excessive rotation of the feeder engineering hidden danger..
aiming at the pain point that the lubricating grease is easy to solidify in high latitude areas, we have solved the problem that the starting current of the rotator is too large in the low temperature environment and the motor is easy to burn.
In view of the pain point of large mechanical gap in the radar tracking process, we solved the problem of unstable target locking and signal gain fluctuation caused by excessive gear recoil..

For the government, ports or large factories and mines to build wireless private networks, stable and reliable base station antenna pointing control system is required to ensure long-term operation of the link without failure.
responsible for receiving satellite data such as meteorology and scientific research, and requires a heavy-duty rotating platform with high precision, supporting automatic tracking and capable of carrying heavy dish antennas.
Undertake infrastructure construction such as radio and television, emergency early warning system, and find source manufacturers to obtain customized products with high cost performance and industrial grade parameter standards.

In complex environments such as mobile command vehicles and temporary observation points, heavy-duty azimuth positioning equipment with earthquake resistance, corrosion resistance and high protection performance is required.
Ensure that the rotator is installed on the horizontal support plate inside the tower. It is recommended to use stainless steel bolts and flat washers. The installation must ensure that the center axis of the rotator is fully aligned with the support bearing at the top of the tower to avoid eccentric forces damaging the internal bearing..
After the first power-on, the controller operates the antenna to rotate clockwise to the physical edge, and uses the software menu to set the electronic stop position. Be sure to leave a margin of at least 20 degrees before the antenna feeder winding limit to prevent cable pull damage..
After the wiring is completed, the waterproof gland of the base must be tightened, and it is recommended to wrap a layer of anti-ultraviolet self-adhesive tape on the outside to ensure that rainwater will not penetrate into the internal terminals along the control cable..
It is recommended to check the tightness of the tower fixing bolts before the windy season of each year. Thanks to the permanent lubrication design of the gearbox, users do not need to disassemble and refuel themselves, but only need to confirm that the external moving parts are free of freezing and dust..
Answer: In the standard tower installation mode, it can withstand a maximum wind area of 3 square meters, and it can remain locked even at a wind speed of 130 kilometers per hour.
A: No. The rotator uses non-volatile storage, and the worm gear structure will automatically lock when the power is off, and the antenna direction will remain in the position before the power failure.
Answer: Support. The supporting controller provides a standard communication interface, which is compatible with most of the mainstream antenna control software on the market for automatic star finding.
Answer: As the cable length required for each project is different, the standard package does not contain long-distance cables, but we can customize and provide matching specifications according to your order requirements.
Answer: If the total weight of the antenna and support rod exceeds 200kg, it is strongly recommended to add a thrust bearing at the tip of the tower to share the longitudinal pressure of the rotator and extend its service life.
Answer: As the source factory, we provide a one-year full-machine warranty for all industrial-grade heavy-duty rotators, and provide lifelong remote technical support and accessories supply.
