This 4-button remote control delivers seamless, secure operation for 24V-powered cranes and heavy machinery, combining durability, versatility, and user-friendliness. As a best-selling radio remote control system, it’s engineered to meet the rigorous demands of industrial environments, offering factory-direct pricing and customizable options. Whether for construction cranes, winches, or material handling equipment, the F21-4S is a top choice for reliable remote operation.
Equipped with 4 responsive single-speed buttons, the F21-4S enables precise control of crane movements (UP/DOWN, EAST/WEST) and auxiliary functions. The self-locking and jog modes provide flexibility, allowing operators to adapt to different tasks—from continuous lifting to precise positioning. This precision reduces operational errors and boosts work efficiency.
Optimized for 24V industrial equipment, the remote also supports DC/AC 12V, 48V, 110V, and 220V, ensuring compatibility with diverse machinery. Its wide voltage range makes it a versatile solution for various industrial setups, eliminating the need for multiple remote controls.
Featuring IP65 protection and a reinforced nylon plastic housing, the F21-4S is waterproof, dustproof, and drop-resistant. It withstands rain, dust, and impacts in construction sites, ports, and warehouses, ensuring long-term reliability in harsh conditions.
With a standard control distance of 100 meters (customizable to 500 meters), the long-range crane remote control allows safe operation from a distance, protecting operators from hazards. The 32-bit security code (4.3 billion unique combinations) prevents signal interference and unauthorized access, ensuring stable communication.
Powered by 2 alkaline AA batteries, the transmitter offers long standby time, reducing battery replacement frequency. The large-capacity battery ensures continuous operation throughout work shifts, minimizing downtime.
