Radio Remote Control For Cranes

We are offering radio remote control for cranes.
The remote radio modules are ce complaints and work on free 2.4ghz ism frequency bandwidth.
The major differences between the other remotes in the industry and ours is as follows:
1. the remotes available in the market use 433 or 865 mhz frequency bandwidth whereas we use 2.4gh frequency bandwidth which is more reliable and there is no data loss.
2. the regular industrial remotes use frequency switching for grouping purposes, where they switch the transmition frequency by a few hz. This is a main cause for the data loss as the antenna structure is specifically ideal for only one frequency and if the frequency is changed, one needs to change the antenna accordingly. we on the other hand, do not use frequency change; the grouping is done by our microcontroller equipment inside receiving unit, so it is more reliable.
3. the regular industrial remotes use normal radio modules which are cheap; they tend to cross talk with other modules within the area of their broadcast. We use the best module available with four layer 16 bit security, which is highly accurate to talk only to the module of which the address is been issued to.
4. the regular remotes tend to get malfunctioned by electrical surges and emfs produced by electrical sparks and heavy current passing nearby, but in our case, high frequency and security towards spikes and spark mode rejection allows to securely transfer on air data.
the walnut radio remote transmitter has 7 single depression push buttons with start emergency stop button. Transmitter status, charging status & low battery indication can be monitored via indicating led available on transmitter.
The receiver of the system has 8 (6 start stop) potential free contact relays which user can configure as per the requirement. Relay indication led available on receiver.
