Telecrane Radio Remote Control
The F21-E1B is a single or double speed radio remote control for cranes, hoists, winches and mobile lifting equipment, supplied as a matched transmitter and receiver pair. It operates on 310-331 MHz or 426-445 MHz with 160 channel
What The Telecrane Radio Remote Control Is For
The F21-E1B is a single or double speed radio remote control for cranes, hoists, winches and mobile lifting equipment, supplied as a matched transmitter and receiver pair. It operates on 310-331 MHz or 426-445 MHz with 160 channels and over 4.3 billion unique ID codes, ensuring no interference between nearby cranes. The set is rated IP65 and works reliably in outdoor yards, dusty workshops and wet environments. Transmitter voltage is DC3V from two AA batteries, and the receiver is built to order from DC12V, DC24V, AC36V, AC48V, AC110V, AC220V or AC380V, so it connects directly to an existing control panel without a transformer.
What You Get From This Unit
- Operator can control the crane from the ground or from a safe distance without walking with the load
- Up to 100 metres control range allows operation from any position around the machine
- IP65 protection keeps the transmitter and receiver working in rain, dust and wash-down areas
- Over 4.3 billion unique ID codes prevent interference between cranes in the same bay
Telecrane Radio Remote Control As Supplied
Where This Model Is Used
- Overhead and bridge cranes in fabrication shops where the cab view is blocked
- Mobile lifting equipment, electric carts, and hoists used in outdoor or wet environments
- Retrofit of an existing pendant-controlled crane without changing the motor panel
- Construction sites where the operator needs to move freely around the load
- Maintenance teams replacing a failed or damaged pendant station
Buyers This Model Suits
- Crane and hoist OEMs specifying controls into new machine builds
- Equipment dealers stocking a control unit that fits multiple voltages
- Maintenance contractors replacing a lost or broken transmitter
- Traders sourcing a radio control set from China at low MOQ
- Operators needing a safe, hands-free way to control a crane from the ground
What Goes Wrong Without It
- Operator must walk with the load while holding a pendant cable that snags on structures
- Cab operator cannot see the hook and relies on a second person to signal
- Existing panel runs AC110V and a standard 24V receiver would need an extra transformer
- Two cranes in the same bay respond to the wrong transmitter
- Pendant cable and plug fail repeatedly in wet or dusty conditions
How The Unit Is Built
- 10 push buttons: 7 double speed function buttons, 1 emergency stop, 1 on/off switch
- 14 control motions from the seven double speed buttons
- Transmitter LED flashes green while battery power is sufficient and red when depleted
- Operating frequency available at 310-331 MHz or 426-445 MHz
- Transmitting power less than 10 mW

What The Housing And Contacts Are Made Of
- Glass fibre transmitter and receiver housings for impact resistance on a shop floor
- Sealed relay contacts rated 5 A so the receiver switches contactor coils directly
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 arrow tips or as your own English labels
- Two transmitters paired to one receiver, or a spare transmitter added to the set
- 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-E1A with 4 buttons | The 7-button F21-E1B adds three more double speed motions; if the machine only has hoist, long travel and cross travel the 4-button model is the cheaper fit |
| F21-E1C with 10 buttons | The 10-button model adds three more motions; if the machine only needs seven motions, the E1B is the more cost-effective choice |
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: 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 DC12V, DC24V, AC36V, AC48V, AC110V, AC220V or AC380V, 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 160 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, six sets per carton at 76.3 x 49.3 x 33 cm.
