SKY 301/302

SKY-301 / 302 Radio Remote Control – Compact, Reliable Wireless Solution for Light-Duty Crane and Hoist Operations

The SKY-301 (Single-Speed) and SKY-302 (Double-Speed) are compact, industrial-grade radio remote control systems engineered for basic crane, hoist, and motion control operations in small to mid-scale environments. Featuring 6 responsive pushbuttons, IP65-rated enclosures, and robust RF communication, this system delivers safe, wireless command transmission across essential motions like hoist, trolley, and bridge travel.

Designed for entry-level or limited-motion systems, the SKY-301/302 offers an excellent balance of reliability, simplicity, and durability, while ensuring the same security and performance standards expected from professional remote systems.

Whether you’re operating a monorail hoist, a compact EOT crane, or a chain pulley system, the SKY-301/302 keeps your equipment responsive, secure, and efficient.
