Remote Control for Mobile Cranes, Model SF-A700, is a wireless remote-control system designed for use in various industries, such as crane operations and mobile machinery. From Henan Safersync Technology Co., Ltd, this remote-control system is of IP65 protection grade.

It is resistant to both dust and water. The system’s housing is made of glass fiber reinforced nylon, offering strength and resilience even in harsh conditions.

The SF-A700 features two joysticks with four-speed dual-axis universal controls, and an array of buttons including toggle switches and self-resetting buttons gives good usability. A built-in low battery alarm ensures continuous operation, while the system offers a wireless frequency range of 430-434 MHz, with up to 199 wireless channels.

With a power supply from a 7.4V lithium battery, it operates at temperatures between -20°C and +65°C, ensuring flexibility and reliability for crane operators.
