The wired and wireless technology for controlling crane:
Electronic machines or objects can be controlled by either wired or wireless systems. In wired technology, the cable wire is used for controlling the device or machine. While the wireless systems use the radio waves frequency to control the end devices. And both the device can be used for controlling the cranes.
The cranes also have different types such as static cranes and mobile cranes. The static cranes are those cranes that cannot be moved from one place to another. And the crane which can easily move from one place to another is known as a movable crane.
In the crane pendant, the cable wire is suspended from the hoist which is used by the operator. And in the case of wireless technology, the crane can be operated from a safe and long-distance and the operator doesn’t have to go closer to the crane.
While using the radio remote control the transmitter device generates artificial waves to control the heavy electronic machines or equipment. The transmitter device has many push buttons for commanding the crane in a specific manner like long travel, cross travel, and hoist. The hoist is a part of a crane that is used for moving heavy objects in a downward and upward direction.
How wireless technology is used for controlling the crane and hoist:
The radio remote control for cranes works wirelessly with the help of radio waves technology. The electromagnetic waves which vibrate at the frequency range of ten KHz to three hundred GHz are classified into radio waves and microwaves respectively. The radio doesn’t require any medium to travel, unlike the sound waves.
For wireless communication, there are two units required such as transmitter and receiver. The transmitter is a small handheld device that is used for sending the signal. And the receiver is used for receiving the signal which is attached to the overhead crane. The receiver has an antenna towards which it gets the signal from a transmitter.
The transmitter sends the data packet to the receiver always in the end-to-end encrypted mode for the safety of the data packet. When the data reaches the receiver end the receiver first decodes the data and converts the data into readable format. The receiver also transmits a signal to the transmitter as an acknowledgment.
The transmitter device adjusts the power automatically according to the distance while close loop communication. That means if the distance is more in the middle of transmitter and receiver then the transmitter device takes more energy. And if the distance is short it consumes less energy.
The industrial crane remote control system notices many things while communicating with the receiver like signal quality, the gap between transmitter and receiver, the lost packet, the number of successful transmissions, the error that occurred, the range of a signal, etc. This communication process in the middle of receiver and transmitter happens more than ten times in a second.
Benefits of hoist crane wireless remote control:
1) The transmitter device uses the hopping frequency technique to avoid unwanted trespassers.
2) The range of the transmitter device can reach ten meters to two hundred meters according to the signal.
3) If any error or lag is found during the transmission process then the transmitter device stops working immediately.
4) During close loop communication the radio remote device adjusts the power automatically depending upon the distance.
5) The frequency used by the transmitter device is 2.4 GHz which is used globally.
6) The battery used for the transmitter device is durable and long lasts a minimum of six months.
7) While transmission the transmitter can send the signal to the receiver more than ten times in a second.
8) The radio remote device is highly optimized and customized while in use.
9) The transmitter device is built in such a way that it can protect from shock and corrosions.
10) The encryption technique used by the transmitter device while sending the signal to the receiver.
11) The transmitter device gets feedback from the receiver device indicating that data reaches successfully.
Closure:
Now we came to know that the EOT crane remote control has more features than the wired crane pendant systems. The crane pendant is costly than the wireless radio remote because it uses cable wire for the transmission of the signal. Due to all these features, there is a more requirement of wireless radio remote device.
The crane remote control manufacturers in India are done by the Anand Systems Engineering Private Limited. The radio remote device is highly customized and optimized according to the use. The transmitter device is made according to the need of customers.
The wireless transmitter device is configured with the interlocked feature in a pair of buttons. To buy the transmitter and for the crane remote control price you can check out the official website.
