1. The crane is equipped with a wireless remote control system. The remote control commands must be consistent with the original cab operation commands, and can realize the function conversion of the two operation modes, matching the corresponding bell, lighting and other functions.
2. The crane has a four-mechanism five-speed control (in line with Chinese crane operating habits): main trolley, auxiliary trolley, main hook, and auxiliary hook.
3. The remote control is of joystick type (receiver power supply AC220V, operating range: ≥100 meters).
4. The remote control has a start button, an emergency stop button, and a red safety rotary switch that complies with national standards.
5. The remote control has high anti-electromagnetic interference performance, adopts a duplex working mode, two-way communication, and continuous signal transmission to prevent interference.
6. The transmitter has a battery voltage warning device. When the battery power is low, a red light will flash as a warning. When the transmitter is out of range, the voltage is low, or the remote control fails after issuing an action command, the receiver will automatically shut down to ensure safety.
7. The receiver has a dual CPU circuit, one for decoding and one CPU circuit specifically monitoring the safe operation of the system. If an incorrect command is input, it can cut off the remote control output to ensure the correct output of each action command.
8. The transmitter is equipped with a user-configurable PIN password lock to prevent unauthorized access to the system.
9. The transmission principle adopts GFSK and TDMA technology. The wireless transmission of the system can optionally use frequency-hopping communication or fixed-frequency communication working modes to eliminate most interference. When using frequency-hopping communication, the frequency will automatically switch between 15 different frequencies. The transmitter housing must be sturdy and durable, oil-proof, acid-resistant, alkali-resistant, corrosion-resistant, strong, wear-resistant, impact-resistant, drop-proof, and non-breakable.
10. The remote control system transmitter has a fine-tuning function. During fine-tuning, only one mechanism has one-speed output. Even if the joystick is in other gears, there is no output.
11. The transmitter has four automatic shutdown time options after being idle for a period of time.
12. The transmitter has a tilt sensor with four options: 45 degrees, 90 degrees, 135 degrees, or no setting. If the transmitter tilts beyond the set angle in special circumstances, the receiver will not operate when the joystick is operated.
13. The remote control for variable frequency cranes needs to have a variable frequency inverter reset switch.
14. The CIM card is used to store configuration information. You can remove the CIM card module from one system and place it in a transmitter with the same programming system, and it will work the same way. This achieves the effect of multiple remote control systems only needing one receiver as a general spare unit for emergency handling, reducing the cost of spare parts.
15. The display screen displays real-time wireless signal quality, text fields (crane ID, etc.), battery power, and alarm information. The display is clear even in bright sunlight.
16. The transmitter and receiver have an IP67 protection level, good dust and water resistance; operating temperature -25℃-+55℃.
17. Using SMART RADIO technology, the signal output power is automatically adjusted according to the signal strength, increasing the continuous operating time.
18. The transmitter uses a lithium battery and can be used continuously for a long time.
19. The charger is professionally designed, and the charging time is only two hours.
20. The transmitter has a built-in alarm bell and vibration device to effectively remind the operator in case of an alarm.
21. Each mechanism of the receiver has a safety relay to control each mechanism in common. After the joystick returns to the zero position, the common line is forcibly disconnected to prevent the crane from malfunctioning due to relay contact sticking, ensuring high safety level.
