High-temperature cranes serve steel mills, foundries, and heat-treatment plants where radiant heat, dust, and continuous duty demand careful specification. The main technical parameters include rated lifting capacity, span, lifting height, working duty class, maximum ambient temperature, insulation class, and protection rating. For example, a heat-resistant crane may be rated for 5-100 t, a span of 10-40 m, and an ambient temperature of 40-80 C, with heat shields, high-temperature cables, and H-class insulation protecting motors and controls. Trolley positioning depends on travel speed, acceleration, encoder resolution, sensor type, and control cycle time. A PLC with closed-loop feedback can achieve repeatable stopping accuracy of +/-5 mm to +/-20 mm, while anti-sway logic limits load swing. Laser distance sensors, absolute encoders, and limit switches should be mounted away from direct heat or fitted with cooling and protective covers. Braking distance, buffer clearance, and emergency-stop response must match trolley speed and load. Regular calibration, thermal inspection, and lubrication checks keep positioning stable. Key control parameters include positioning repeatability, response time, motor torque, inverter settings, and communication protocol, while safety limits cover overtravel, overload, overtemperature, and emergency braking. These parameters help engineers select a safe, efficient high-temperature crane and trolley positioning system. Ensure safe fast handling.
