The wireless radio remote control is used to control the crane and hoist. The transmitter and receiver is used for sending and receiving the signal. The communication in the middle of receiver and transmitter happens more than ten times in a second.
What is radio remote control and its types:
The name wireless itself implies that heavy machines or electronic types of equipment can be controlled remotely. Hence the wireless devices use radio waves technology to control the movement of electronic machines.
The transmitter devices generate artificial waves to communicate with the end devices. This process is called a radio remote control. This device is used for the industrial sector to control heavy machines like cranes.
The cranes can also be subdivided into two parts such as static and mobile cranes. The crane which moves from one place to another place is known as a mobile crane and the crane which cannot move and is fixed at some point is called a static crane.
The overhead crane travels and works above the head at a specific distance of height. This type of crane can be managed by a remote control device such as push-button remote control and joystick remote control. The radio remote device can move the crane in an appropriate direction like long travel,
cross travel and, hoist. The hoist is a part of the crane which is used to move the heavy-duty loads in upward and downward directions.
Working process of radio remote control for EOT cranes:
The pushbutton devices communicate with the end devices when the signal is sent from the transmitter device. The push-button radio remote has many types like 2 buttons, 4 buttons, 6 buttons, 8 buttons, 10 buttons, and 12 buttons. While the joysticks remote device doesn't have a push-button they work on only two stick buttons.
Both the remote devices are can move and control the cranes. The transmitter is a small device that is used by the ground operator to control the crane. While the receiver is placed at the overhead crane's location. The receiver has an antenna through which it receives the signal from the transmitter device.
The signal is sent to a receiver in an encrypted form when the operator pushes the button on the transmitter device. When this data packet reaches the receiver than receiver first decodes the data and converts it onto the readable format. This mechanism happens around ten times in a second.
There are a few things that are observed by the industrial crane remote control system while communicating with the receiver device such as the signal strength, The communication gap, the number of errors occurred, the lost data packet, the signal quality, the number of successful transmissions to the receiver, the feedback from receiver, the range, the battery power, etc.
The receiver also transmits the signal to the transmitter device as feedback that sent data packet reached successfully. In between that the transmitter device adjusts the electric power automatically according to the length. The transmitter device has the feature of interlocked systems that means two buttons in the pair cannot be used at the same time.
Precedence of crane wireless remote control:
The wireless remote control for overhead crane uses wireless technology for transmission of signal hence it pulls out the wired cable systems that result in less expensive. For transferring the signal the transmitter device uses the 2.4 GHz frequency band which is the latest and used across globally.
The transmitter and receiver perform close-loop communication while communicating with each other. Because of this, the radio remote control adjusts the power automatically depending on the distance. If the distance is more in the middle of transmitter and receiver then the transmitter device consumes more energy. And if it is less the transmitter device takes less energy.
Due to the wireless technique, the operator doesn't have to go close or sit inside the crane that helps minimize the risk factor. The operator can easily control the crane from a safe and long-distance. The transmitter works on the battery system which is durable and can last a long minimum of six months.
While transmission of signal the hopping frequency techniques are used by the hoist crane wireless remote control to avoid unwanted errors and to keep changing the continuous transmission of the signal. The communication in the middle of the transmitter and receiver takes place more than ten times in a second.
Closure:
The joystick remote control and push-button remote control have their specifications and features. The joystick radio remote can move the crane 5 steps ahead where the push-button radio remote can move the crane in 2 steps. The push-button remote control is more used as compared to the joystick radio remote. Hence the many manufacturing companies produce radio remote control devices.
The best crane remote control is manufactured from the Anand Systems Engineering Private Limited. The built quality of the radio remote device is made in such a way that it can protect from shock and corrosion. The remote control device is highly optimized and customized. The transmitter device performs well in harsh industrial conditions. For the crane remote control price and its specification visit the official website.
