A rail transfer trolley, also known as a rail transfer cart or rail-guided trolley, is a type of material handling equipment designed to move heavy loads along a fixed track system. These trolleys are widely used in factories, warehouses, shipyards, and other industrial environments where heavy items such as steel coils, large machinery, and bulky components need to be transported efficiently. Technical Principle: Power Supply System: The AC 380V power supply is stepped down to AC 36V three-phase through a transformer and connected to the three rails. The wheels and conductive sliders on the rail car transfer the AC 36V power from the three tracks into the onboard electrical box. Boost and Control System: Inside the vehicle's electrical box, a boost transformer increases the three-phase AC 36V to three-phase AC 380V. The AC control system then regulates the AC metallurgical motor, enabling the flat car to execute commands such as starting, stopping, moving forward, and moving backward. Rail Transfer Trolley Features: Strong Load Capacity: Designed with a load capacity of 10 tons, allowing it to easily handle heavy equipment and materials. Low-Voltage Track Power Supply: Utilizes a low-voltage (typically 36V three-phase) track power supply. Electrical energy is obtained through the wheels using conductive sliders or electric carbon brushes from the track. The onboard electrical box then uses a boost transformer to increase the voltage to a level suitable for motor operation (such as 380V), driving the motor efficiently.
