The travel mechanism enables the ship unloader to move horizontally along the dock or rail tracks, allowing it to position accurately at different cargo holds of the ship for efficient material transfer.
Typical parameters include a rated load capacity of 500-2000 t, travel speed of 20-40 m/min, rail gauge of 10.5-22 m, max wheel load of 250-600 kN, number of wheels 8-32, drive power per motor 15-45 kW, power supply 380-690 V AC, operating temperature -20 to 45°C, ingress protection IP54-IP65, braking torque 200-800 N·m, wheel diameter 500-1000 mm, and total weight 50-200 t. These are reference ranges; confirm with the manufacturer.
Precise positioning is achieved through guidance systems such as rails, sensors, or laser alignment, which continuously monitor and correct the unloader's path along the designated route.
Signs include unusual noises from drive motors or gear reducers, excessive wheel wear, misalignment on the rails, reduced braking effectiveness, or overheating of electrical components. Regular inspection of wheels, brakes, and guidance sensors is recommended.
