Radio control of crane

Radio control of crane is a remote control of a hoisting-and-transport mechanism using radio signal to equipment (basic equipment always consists of a receiver, a module for controlling a crane and a radio transmission unit and a control panel). The control panel, in its turn, can be presented as a joystick, an apparatus with buttons or a programmable logic glove. Thanks to transmitter power up to 5mW (and operating frequency bands from 415 to 483 MHz), such remote systems can be used without special permissions – this is a requirement to ensure safety when operating remote control systems.

Radio control is currently more a necessity than additional functionality for a crane control system, when there is an opportunity for the crane operator to be on the foot (especially if the lifting height of the load is large, and there is a need to perform precise operations quickly).

With the help of remote control systems, it becomes possible not to use the operator’s cabin and suspension consoles and to control the lifting-transport mechanism at any convenient point of the device’s operating radius. This is true for limited space accommodation crane beams (there is no place to accommodate the cabin).
The main advantage of the remote control system is a small device mass, ergonomics, low transmitter power and a large radius of application. To ensure the safety of the crane operator, it is possible to adjust the crane operation zones and monitor the location of the crane operator, so that when the crane operator is in the danger zone, an auto-stop of the load lifting mechanism can be done.

• The overview of the crane operator is not limited to the cab, so the location of the cargo can be determined more accurately;
• There is an opportunity to choose the best and safe points of work with cargoes;
• It is easier to train personnel to work with a remote control system;
• Allows any personnel to learn and work as a crane operator without having a separate crane operator position.
