Remote Control System

The Remote Control System is a critical electronic component of a Portal Crane that allows operators to control crane functions such as hoisting, trolley movement, gantry travel, and load handling from a safe distance. It typically consists of a handheld transmitter, receiver unit, and interface electronics that communicate with the crane's main control system, providing real-time feedback and safety monitoring. The system operates by converting operator inputs from a handheld transmitter into digital or radio frequency signals, which are transmitted to a receiver unit on the crane. The receiver decodes these signals and relays commands to the crane's programmable logic controller (PLC) or main control unit, which then activates the appropriate motors, brakes, and safety systems to execute the requested movements. This product is intended for integration into portal crane systems and is not a standalone machine. It is designed for use in industrial environments, with a control distance of 100–300 meters for wireless operation (line of sight) or limited by cable length for wired versions. The number of control channels ranges from 8 to 32, allowing fine control of crane functions. Response time is between 50 and 200 milliseconds, contributing to safety and precision. Operating voltage is 24 V DC ±10%, and power consumption is 10–50 W. The system operates within a temperature range of -20 to 60 °C, with a protection class of IP54 to IP65, and humidity range of 10–95% RH (non-condensing). For wireless models, the frequency range is 2.4–2.4835 GHz (ISM band) with transmission power of 10–100 mW, per ETSI EN 300 328. The combined weight of transmitter and receiver is 2–15 kg. Materials include electronic components, plastic housing, and metal connectors. These specifications are reference ranges; actual values must be confirmed with the legal manufacturer or supplier for the specific model and application. Standards listed (e.g., IEC 60068-2-1/2, IEC 60529, ETSI EN 300 328) are procurement references and do not imply certification of any specific product.
