As a best-selling product trusted by global clients including China State Construction and EUROCRANE, this single-speed remote control integrates mature technology, rugged construction, and user-centric design. It features 4 intuitive single-speed buttons, ensuring precise operation of lifting, lowering, and horizontal movement of cranes. With a default control distance of 100 meters (customizable up to 500 meters), the F21-4S industrial remote control adapts to various job site sizes, while its IP65 protection grade and wide temperature range (-35℃~+80℃) make it ideal for harsh outdoor and industrial environments. Whether for tower cranes, gantry cranes, or port hoisting equipment, the F21-4S delivers consistent performance that drives efficiency and safety.
Crafted with a reinforced nylon plastic housing, the F21-4S meets IP65 protection standards, providing complete waterproof and dustproof performance. This feature shields internal components from rain, dust, and construction debris, reducing maintenance costs and extending service life—critical for outdoor construction sites where equipment is exposed to harsh elements.
Equipped with 4 responsive single-speed buttons (UP/DOWN/EAST/WEST), the remote control offers straightforward operation, minimizing training time for operators. The self-locking and jog function options (customizable) enhance operational flexibility, allowing precise control of crane movements to avoid load damage or safety hazards.
Boasting a standard control distance of 100 meters (UHF 420450mhz frequency), the F21-4S supports customization up to 300500 meters to meet large-scale job site needs. The UHF frequency band ensures stable signal transmission with minimal interference, enabling operators to control cranes from safe, convenient positions.
With a 32-bit unique security code (4.3 billion non-repeating groups), the F21-4S eliminates signal crosstalk between multiple devices on the same site. This high-security design prevents accidental activation of other machinery, safeguarding personnel and equipment.
Supporting DC/AC 12V, 24V, 48V, 110V, 220V, and 380V (50-60Hz), the remote control seamlessly integrates with most crane models and industrial equipment, eliminating the need for additional voltage converters and reducing installation complexity.
