Detailed Answer
Metallurgical crane weighing interlock: when load exceeds limit, the weighing system locks remote hoisting (hardwired interlock) to prevent overloaded lifting. Remote control receiver reserves weighing signal input terminals (Lideral LD series), interlocking with weighing instrument. On overload alarm, remote hoisting is invalid — a metallurgy safety-critical function.
