What The Wireless Control Air Hoist Is For
The F21-2S-2TX is a single speed wireless remote control for air hoists, chain hoists, winches and mobile lifting equipment, supplied as a matched transmitter and receiver pair. Two function buttons provide basic control of lift and lower motions, with a mushroom emergency stop button for safety. The system operates on 80 channels across 310-331 MHz or 426-445 MHz, with a control range up to 100 metres. Both units are rated IP65, making them suitable for dusty, wet or outdoor environments without additional protection. Receiver voltage is selected at order time from AC380V, AC220V, AC110V, AC48V, AC36V, AC24V, AC12V or DC12V, so it can be installed directly into an existing control panel without a transformer.
What You Get From This Unit
- Operator can control the hoist from a safe distance without being tethered by a pendant cable
- IP65 protection allows use in dusty, wet or outdoor environments without a cover
- Single speed operation is simple to train and reliable for basic lifting tasks
- Receiver voltage built to order avoids adding a control transformer to the panel
- Over 4.3 billion unique ID codes prevent interference from other nearby controls
Where This Model Is Used
- Air hoists and chain hoists in fabrication shops and maintenance bays
- Mobile lifting equipment and electric carts where the operator needs freedom of movement
- Winches and super winches used in construction or mining sites with harsh conditions
- Retrofit of an existing hoist with a pendant control that fails in wet or dusty areas
- Control of a hoist where the operator cannot stand near the machine due to safety or layout constraints
Buyers This Model Suits
- Crane and hoist OEMs integrating wireless control into new equipment
- Maintenance teams replacing a failed or worn pendant station on a hoist
- Equipment dealers stocking a control unit that fits multiple voltages and applications
- Traders sourcing a low MOQ wireless control set from China for the UK or European market
What Goes Wrong Without It
- Operator must walk with the hoist while holding a pendant cable that drags on the floor or gets snagged
- Existing pendant control fails in wet or dusty environments due to exposed contacts
- Control panel runs AC110V and a standard 12V receiver would require an extra transformer
- Two hoists in the same area respond to the same transmitter due to unpaired signals
- Operator cannot see the hook or load from the pendant station location
How The Unit Is Built
- 2 function buttons for lift and lower, 1 emergency stop (mushroom), 1 start button
- Crystal plug-in frequency generation across 80 channels at 0.2675 MHz spacing
- Operating frequency: 310.0325-331.165 MHz or 426.0325-445.165 MHz
- Control range up to 100 metres in open space
- Transmitter LED flashes slowly when voltage drops below 2.2 V; unit will not start below 1.8 V
- Transmitter LED flashes quickly if the start sequence is incorrect or a button is jammed
- Full sealed relay outputs rated 5 amperes for direct contactor switching
- Glass fibre-reinforced nylon-6 housing on both transmitter and receiver for impact resistance

What The Housing And Contacts Are Made Of
- Glass fibre-reinforced nylon-6 housing on both transmitter and receiver for impact resistance on a shop floor
- Sealed relay contacts rated 5 A so the receiver switches contactor coils directly without external relays
How This Unit Is Made
Step 1
Boards are populated on the SMT line and soldered on the automatic wave soldering machine
Step 2
Transmitter and receiver are paired to a unique ID code and channel before assembly
Step 3
Each set is function tested against the ordered receiver voltage before packing
Step 4
S/N and channel are printed on the back of both units so a replacement can be matched later
What Is Checked Before It Ships
- Raw material through finished product is inspected step by step on the production line
- Working process follows ISO9001:2008
- Every set is powered up and each motion is checked before it leaves the line
- 12 month warranty from delivery
What Can Be Changed On Your Order
- Button text supplied as arrow tips or your own English labels
- Two transmitters paired to one receiver, or a spare transmitter added to the set
- Receiver voltage selected from AC380V, AC220V, AC110V, AC48V, AC36V, AC24V, AC12V or DC12V at order time
- Own brand and label printing accepted on OEM orders
How It Compares With The Alternatives
| Wired pendant control station | Radio removes the trailing cable but adds batteries to change and a receiver to wire in; a pendant is cheaper and never needs pairing |
|---|---|
| F21-4S-4TX with four buttons | The 2S-2TX is simpler and cheaper for basic lift and lower; if you need more motions, the 4S model adds two extra buttons |
| Double speed remote controls | Single speed is sufficient for basic hoist control and reduces complexity; double speed adds cost and training effort for no benefit in simple lifting |
Getting It Onto The Machine
- Confirm the control voltage on the existing panel before ordering the receiver
- Count the motions the machine actually needs, then choose the button count with one spare
- Mount the receiver inside the panel with the 1 m cable running to the contactor terminals
- Watch the transmitter LED: slow red flashing means change the two batteries
- Record the S/N and channel from the back of both units so a lost transmitter can be replaced without changing the receiver

Frequently Asked Questions
What is the minimum order quantity?
One set. A single sample is available so you can test it on the machine before committing to volume.
How long is delivery?
Around 2-4 days for a sample order and about 7 days for a small volume order, then 3-8 days by FedEx or DHL.
Which receiver voltage should I order?
Match the control voltage on the crane panel. The receiver is built for AC380V, AC220V, AC110V, AC48V, AC36V, AC24V, AC12V or DC12V, so tell us the panel voltage with the order.
Can I get a replacement transmitter only?
Yes. Send the S/N and CH printed on the back of your receiver and we build a new transmitter on the same channel, so the receiver stays in place.
Will two hoists in the same bay interfere?
Each set is coded with one of over 4.3 billion unique ID codes and runs on 80 channels, so a transmitter only answers its own paired receiver.
Can the button text be changed?
Yes. Arrow tips are standard and your own English button text and brand can be printed on OEM orders.
How is it packed?
One set per box at 16.5 x 8.5 x 6.5 cm, six sets per carton at 40 x 30 x 25 cm.
