Updating your crane to wireless remote control is an easy way to improve safety. The wireless crane remote control allows the operator to move freely and get a better view of the load. Better ergonomics reduce operator stress while increasing productivity.
How does wireless crane remote control work?
What are the components of wireless crane remote control?
What is the wiring method of the wireless crane remote control?
The wireless crane remote control can be divided into two types according to its working principle: infrared remote control and radio remote control. Most of the industrial remote controls used by industrial and mining enterprises are radio remote controls. The radio remote control is issued by the transmitter after the button signal is coded and modulated and converted into an electromagnetic wave signal; the receiver filters and amplifies the received electromagnetic wave signal and then identifies it by decoding, which is used to control relays and drive electrical components and motors, thus realising the remote control operation of the crane. wireless crane remote control is mainly composed of a transmitter, a receiver and an actuator. 3 parts: transmitter, receiver and actuator.
The transmitter is portable and has the characteristics of small size, light weight and easy operation. There are two types of operation: push-button type and rocker type. The push-button type is suitable for simple small cranes and has 8-21 operating commands. The joystick controller is suitable for all types of cranes and has 12-52 operating commands. The transmitter is powered by a rechargeable battery pack. The housing is generally made of reinforced plastic, impact resistant, waterproof, dustproof, oil resistant, small in size and light in weight. 2.
2. The receiver is mainly composed of an antenna, high-frequency receiving components, the CPU used to process the signal, safety circuits, output relay boards and other parts. After receiving the operating instructions, the receiver generates control signals through amplification, demodulation, decoding and identification, and outputs them to the actuator to control the operation of the corresponding crane mechanism.
3. The actuator consists of relays and contactors to control the operation of the corresponding crane mechanism.
1, 2 wire to the power supply, for example, the remote control is 380V, then 380V, 36V then 36V. must not be connected to the wrong, wrong connection will burn the remote control inside the transformer. wireless crane remote control working voltage is in the remote control shell above.
COM is connected to the power supply, which is the same as the working voltage of the contactor on the crane. The red wire is connected to the main contactor coil, i.e. KM, and the yellow and green wires are connected to the upper and lower contactor coils, e.g. KM1 and KM2, which control the up and down of the crane, then the yellow and green wires are connected in parallel to SB1 and SB2. All others are the same, and so on.
