What The Industrial Radio Remote Control Is For
The F21-E1B is a single speed industrial radio remote control for EOT cranes and hoist lifting equipment, supplied as a matched transmitter and receiver pair. It operates over a range of 100 to 150 metres with a crystal-structured frequency system and features 8 function buttons including start and stop. The set is rated IP65 for dust and water protection, making it suitable for outdoor and harsh shop floor environments. Receiver voltage is selected from AC110V, AC220V, AC380V, AC440V, DC12V, DC24V, AC36V, or AC48V, so it can be installed directly on existing control panels without a transformer.
What You Get From This Unit
- Operator can control the crane from the ground without being confined to a cab or trailing a pendant cable
- Single speed operation is reliable and simple to train operators on, reducing errors in routine lifting tasks
- IP65 rating ensures the transmitter and receiver survive rain, dust, and wash-down environments without additional protection
- Receiver voltage built to order avoids the need for a control transformer in the panel
- Over 4.3 billion unique ID codes prevent interference between nearby cranes operating on the same frequency
Where This Model Is Used
- Single girder and double girder overhead cranes in fabrication and assembly shops
- EOT cranes where the cab view of the hook is obstructed by structure or load
- Hoist and winch systems used in construction, mining, or material handling
- Outdoor gantry cranes exposed to rain, dust, and temperature extremes
- Retrofit of an existing pendant-controlled crane without changing the control panel wiring
Buyers This Model Suits
- Crane and hoist OEMs integrating remote controls into new machine builds
- Maintenance teams replacing a failed or damaged pendant station
- Equipment dealers stocking a control unit that supports multiple standard voltages
- Traders sourcing a radio control set from China with low MOQ and fast delivery
What Goes Wrong Without It
- Operator must walk with the load while holding a pendant cable that gets snagged on structures
- Cab operator cannot see the hook and relies on hand signals from a second person
- Existing panel runs AC110V and a standard 24V receiver would require an extra transformer
- Two cranes in the same bay respond to the same transmitter due to shared frequency
- Pendant cable and plug fail repeatedly in wet or dusty environments
How The Unit Is Built
- 8 push buttons: 6 function buttons, 1 start, 1 stop
- 7 control motions from the 8 buttons
- Full sealed relay outputs rated 5 amperes
- Transmitter LED flashes red when battery power is low
- Glass fibre housing on both transmitter and receiver
- Transmitting power less than 10 mW
- Battery voltage warning cuts off power during low voltage condition
- Function buttons programmable via computer software
- Safety magnetic key prevents unauthorized use

What The Housing And Contacts Are Made Of
- Glass fibre transmitter and receiver housings for impact resistance in industrial environments
- Sealed relay contacts rated 5 A to switch 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
- Receiver voltage selected from the listed range at order time
- Button text supplied as standard arrow tips or as your own English labels
- Function buttons can be programmed via computer software for start, normal, or toggle operation
- Own brand and label printing accepted on OEM orders
- Spare transmitter or additional transmitter can be added to the set
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-E1D with double speed | The E1B is single speed and simpler; if the machine needs fast and slow motion control, the E1D is the better fit |
| F24-8D with double speed | The E1B is single speed and lower cost; double speed is needed for precise positioning, but not for basic lifting tasks |
Getting It Onto The Machine
- Confirm the control voltage on the existing crane 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: red flashing means change the two AA 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 AC110V, AC220V, AC380V, AC440V, DC12V, DC24V, AC36V, or AC48V, 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 cranes 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 46 x 24.4 x 14.8 cm, ten sets per carton at 76.3 x 49.3 x 33 cm.
