Short Answer
If you are using an ARC FLEX-style radio remote control on an overhead crane, electric hoist or other industrial equipment, you do not always have to replace it with exactly the same radio system.
A complete JIAYI Q Series transmitter and receiver set can be considered as an alternative when the machine control functions, button configuration, speed requirements, receiver voltage and wiring logic are properly confirmed.
However, the Q Series uses its own transmitter, receiver, radio platform and electrical configuration. It should therefore be treated as a complete control system replacement, not as a transmitter that can be paired directly with an existing ARC FLEX receiver.
What Is the ARC FLEX Remote Control System?
ARC FLEX is a family of industrial radio remote controls commonly used with lifting and material-handling equipment.
Depending on the model, FLEX systems are available with different button layouts and control configurations. The brochure provided for the FLEX series shows configurations including:
- 4-button transmitters
- 6-button transmitters
- 8-button transmitters
- 12-button transmitters
- Single-speed control
- Dual-speed control
- Emergency stop
- Multiple control modes
- Industrial receiver systems
Typical applications include electric hoists, overhead cranes, tower cranes, conveyors and other industrial machinery. The FLEX brochure also specifies features such as 62 selectable channels, automatic channel scanning, IP66 protection and approximately 100 m control distance for the push-button series.
These features explain why FLEX-style controls have become familiar to many crane operators and equipment manufacturers.
But when an older radio control system needs replacement, the real question is often not:
“Where can I find exactly the same transmitter?”
It is:
“Can I install another complete wireless control system that performs the same machine functions?”
In many cases, the answer is yes.
Can JIAYI Q Series Be Used as an ARC FLEX Alternative?
Yes, at the complete system level.
The JIAYI Q Series is designed for many of the same general industrial control applications, including:
- Overhead cranes
- Bridge cranes
- Electric hoists
- Gantry cranes
- Material handling equipment
- Industrial lifting systems
- Other machinery requiring wireless directional control
The operating concept is also familiar.
A typical crane configuration may include:
- UP / DOWN
- LEFT / RIGHT
- FORWARD / REVERSE
- START
- STOP
- Emergency Stop
Single-speed and dual-speed configurations can also be selected according to the machine.
This makes the Q Series suitable for many projects where the user wants to replace an existing FLEX-style crane radio control system with a new transmitter-and-receiver set.
However, similar application does not mean electrical compatibility.
That distinction is critical.
JIAYI Q Series Is an Alternative, Not a Direct ARC Receiver Replacement
This is the most important point when considering a replacement.
A JIAYI Q transmitter should not be purchased with the expectation that it will communicate directly with an existing ARC FLEX receiver.
The two systems use different:
- Radio control platforms
- Control chips
- Receiver designs
- Electrical configurations
- Receiver voltage options
- Pairing and identification systems
Therefore, the recommended replacement method is:
Old transmitter + old receiver → Complete JIAYI transmitter + receiver system
rather than:
Old ARC receiver + new JIAYI transmitter
This approach is also easier to evaluate technically because the new transmitter and receiver are designed to work together as one complete system.
ARC FLEX vs JIAYI Q Series: What Is Similar and What Is Different?
| Item | ARC FLEX Series | JIAYI Q Series |
|---|---|---|
| Industrial wireless control | Yes | Yes |
| Crane / hoist applications | Yes | Yes |
| Push-button transmitter | Yes | Yes |
| Multiple button configurations | Yes | Yes |
| Single-speed control | Available | Available |
| Dual-speed control | Available | Available |
| Emergency stop | Available | Available |
| Custom control functions | Depends on configuration | Available according to project |
| Transmitter platform | ARC FLEX platform | JIAYI Q platform |
| Receiver | ARC receiver | JIAYI receiver |
| Control chip | ARC platform | JIAYI platform |
| Receiver voltage | ARC configurations | JIAYI configurations |
| Direct TX-to-existing-RX compatibility | Within corresponding ARC system | Not compatible with ARC receiver |
| Recommended replacement | Original component or complete system | Complete transmitter + receiver set |
The important conclusion is simple:
The Q Series can provide a similar machine-control solution, but it is not the same radio system.
For a professional buyer, this is normally more important than whether the housings or button layouts look similar.
When Does Replacing the Complete System Make More Sense?
Replacing the entire radio remote control system can be a practical option in several situations.
1. The Existing Remote Control Is Old
An older crane may still operate correctly while its radio remote control becomes difficult or expensive to maintain.
Instead of continuing to search for the exact old transmitter, receiver or spare electronics, the owner may choose to replace the radio control portion of the machine.
The crane itself does not necessarily need to be replaced.
2. The Original Transmitter Is Damaged
If the transmitter is badly damaged and an exact replacement is difficult to source, replacing both the transmitter and receiver can simplify the process.
The key is to confirm the machine control requirements before selecting the new system.
3. The Buyer Wants a More Cost-Effective Alternative
For many industrial users, the main requirement is not maintaining the original radio brand.
Their priority is:
- Reliable machine control
- Correct directional functions
- Correct speed control
- Correct receiver voltage
- Clear wiring
- Easy future replacement
- Reasonable purchasing cost
In this situation, a complete alternative radio system may be more practical than remaining tied to an older proprietary system.
4. The Equipment Uses Standard Crane Control Functions
Replacement is generally easier when the machine uses relatively conventional commands such as:
| Crane Function | Typical Remote Command |
|---|---|
| Hoist | UP / DOWN |
| Trolley | LEFT / RIGHT |
| Bridge | FORWARD / REVERSE |
| Power | START / STOP |
| Safety | Emergency Stop |
For these applications, a replacement system can often be configured around the actual machine functions rather than around the original transmitter brand.
What Must Be Checked Before Replacing an ARC FLEX System?
Do not choose a replacement remote only by looking at the number of buttons.
Before recommending a Q Series system, several technical details should be confirmed.
1. Number of Control Functions
First identify what every button on the existing transmitter controls.
For example:
- UP
- DOWN
- EAST
- WEST
- NORTH
- SOUTH
- START
- STOP
If additional auxiliary functions are used, they also need to be identified.
2. Single Speed or Dual Speed
This is particularly important for cranes and hoists.
A single-speed button normally sends one command.
A dual-speed button can provide two operating stages, such as:
First step → Low speed
Second step → High speed
Do not replace a dual-speed crane remote with a single-speed system unless the crane control circuit is also being changed accordingly.
3. Receiver Supply Voltage
The receiver power supply must be confirmed before production.
Do not assume that two visually similar receivers use the same voltage.
ARC FLEX documentation lists several receiver supply configurations, while JIAYI Q Series uses its own receiver and voltage system.
The correct voltage should therefore be confirmed from:
- Existing receiver label
- Electrical drawing
- Control cabinet
- Transformer output
- Machine documentation
4. Receiver Output Logic
The radio receiver ultimately has to control the crane’s electrical system.
That may involve:
- Contactors
- Relays
- PLC inputs
- Motor control circuits
- Auxiliary devices
For this reason, replacing a radio system is not simply a matter of matching the external button layout.
The receiver output logic must correspond to the machine.
5. Existing Wiring
Whenever possible, provide the existing wiring diagram.
If no drawing is available, clear photos of the receiver terminals and control cabinet are very useful.
A supplier should understand the wiring requirement before recommending the final configuration.
What Information Should You Send Us?
If you currently use an ARC FLEX, FLEX-style or another crane remote control and want to evaluate a replacement, send the following information:
- Photo of the existing transmitter
- Photo of the existing receiver
- Receiver model label
- Receiver input voltage
- Number of buttons
- Single-speed or dual-speed operation
- Function of each button
- Existing wiring diagram, if available
- Machine type
- Quantity required
For many standard crane applications, this information is enough to determine whether a suitable Q Series configuration is available.
Why Consider the JIAYI Q Series?
The purpose of the Q Series is not to reproduce another manufacturer’s electronic system.
Its value is to provide another way to achieve the required industrial machine control.
Familiar Push-Button Operation
Operators can continue using familiar directional commands instead of changing the basic operating method of the machine.
Single-Speed and Dual-Speed Options
Different versions can be selected according to the motor and crane control requirements.
Complete Transmitter and Receiver System
The transmitter and receiver are supplied as a matched control system, avoiding uncertainty about cross-brand radio compatibility.
Custom Button Functions
Button functions, panel markings and control logic can be configured for different industrial machines.
Suitable for Crane Replacement Projects
For older overhead cranes, hoists or industrial equipment, replacing the wireless control system can be more practical than replacing the entire machine control architecture.
When Is the Q Series NOT the Right Replacement?
A professional replacement recommendation should also explain the limitations.
The Q Series is not suitable when the customer requires:
Only an ARC-Compatible Transmitter
If the requirement is:
“I want to keep my ARC receiver and only buy another transmitter.”
Q Series is not the correct solution.
Exactly the Same Original Radio Platform
If the project specification requires the original ARC system or an exact ARC spare component, use the corresponding original component.
A Receiver Voltage or Output Configuration That Has Not Been Confirmed
Never choose an industrial radio remote purely from the transmitter appearance.
The receiver electrical information must be checked first.
A Safety-Critical Special Control Logic That Has Not Been Evaluated
Complex tandem cranes, synchronized lifting systems, PLC-controlled equipment or special safety functions may require additional technical evaluation.
Common Mistakes When Replacing a Crane Remote Control
Mistake 1: Buying by Appearance
Two transmitters can look almost identical while using completely different electronics.
Mistake 2: Assuming the New Transmitter Will Pair With the Old Receiver
Cross-brand pairing should never be assumed.
Always confirm whether you are replacing:
transmitter only
or
the complete transmitter and receiver system.
Mistake 3: Ignoring Receiver Voltage
Using the wrong receiver power supply can cause equipment failure or damage.
Mistake 4: Ignoring Single-Speed vs Dual-Speed Control
The button configuration must correspond to the actual machine control circuit.
Mistake 5: Not Checking the Wiring Before Ordering
A replacement system should be selected based on the electrical control requirement, not only on the number of buttons.
Replace the Remote, Not the Entire Crane
An aging or damaged wireless remote control does not automatically mean that the crane itself needs major modification.
For many conventional overhead cranes and electric hoists, the wireless control section can be replaced as a separate system.
If an existing ARC FLEX system is no longer the preferred option, a complete JIAYI Q Series transmitter and receiver set may provide an alternative.
The important principle is:
Match the replacement to the machine functions, voltage and wiring—not simply to the old remote-control brand.

FAQ
Can a JIAYI Q Series transmitter work directly with an ARC FLEX receiver?
No. JIAYI Q Series uses its own transmitter, receiver and radio platform. If replacing an ARC FLEX system with Q Series, the normal solution is to replace both the transmitter and receiver.
Is JIAYI Q Series the same as ARC FLEX?
No. They are different radio control systems. They can serve many similar crane and hoist applications, but their electronic platforms, receivers, chips and electrical configurations are different.
Can I replace an ARC FLEX 8-button remote with a JIAYI 8-button remote?
Potentially, but button quantity alone is not enough to determine compatibility. Receiver voltage, single- or dual-speed control, button functions and wiring must also be checked.
Can Q Series control an overhead crane?
Yes. Q Series can be configured for common overhead crane functions including hoist movement, trolley movement, bridge movement and emergency stop.
Do I need to replace the receiver?
If changing from ARC FLEX to JIAYI Q Series, yes. The Q transmitter is designed to work with the corresponding JIAYI receiver.
How do I know which Q Series model I need?
Send the transmitter photo, receiver photo, supply voltage, number of buttons, speed configuration and button functions. This information allows the supplier to recommend an appropriate configuration.
Can the button functions be customized?
Yes. Q Series can be configured according to different machine functions and operating requirements.
Is Q Series a rechargeable remote control?
The standard Q Series discussed here is not a rechargeable remote-control platform. If battery configuration is important to the project, confirm it before ordering.
