The dedicated frequency converter for lifting equipment is a power control device designed specifically for cranes, overhead cranes, and other equipment. Through frequency conversion speed regulation technology, it achieves motor soft start, precise speed regulation, overload protection, and energy-saving operation. Our product covers a power range of 7.5KW to 800KW, supports heavy-duty start, four quadrant operation, and energy feedback function, and is suitable for scenarios such as bridge cranes, gantry cranes, and tower cranes.
Heavy load starting capability: Lifting equipment often needs to be started under full load or overload (such as 1.2-1.5 times the rated load), and a dedicated frequency converter can provide instantaneous output of 150% -200% of the rated torque to avoid motor stalling or burnout.
Low speed and high torque control: During the micro movement and precise positioning of the hook, the frequency converter uses vector control technology to achieve a wide frequency range of 0.1Hz-50Hz speed regulation, ensuring that the rated torque can still be output at low speeds (such as 0.5m/min) to prevent cargo from slipping.
Braking energy recovery: When the crane descends or decelerates, the motor is in a generating state, and a dedicated frequency converter feeds back the electrical energy to the grid through an energy feedback unit, reducing the heating of the braking resistor and achieving an energy-saving rate of 20% -60%.
Fast braking response: Supports a combination of DC braking, feedback braking, and energy consumption braking to ensure no slippage when heavy objects come to an emergency stop, improving safety.
Active anti sway algorithm: By detecting the swing angle of the hook and dynamically adjusting the speed of the lifting/operating mechanism, the swing amplitude is reduced by 70% -90%, suitable for scenarios such as port gantry cranes and tower cranes.
Multi motor synchronous control: Supports master-slave control mode to ensure the coordinated operation of multiple motors in the crane, trolley, and lifting mechanism, avoiding mechanical stress caused by speed differences.
No load/light load acceleration: When the hook rises without load, the frequency converter automatically increases the frequency to 55-60Hz, shortening non production time; Limit the frequency to below 50Hz during overload to prevent overload.
Torque compensation function: Provides static/dynamic torque compensation for torque loss caused by frictional loads such as steel wire ropes and pulley systems, ensuring speed stability.
Jogging/Inching Control: Supports JOG mode, achieving millimeter level micro movement, suitable for precision loading and unloading (such as nuclear power equipment installation).
Crawling speed setting: Automatically switches to a low speed of 0.1-1m/min when approaching the target position to improve positioning accuracy.
Light load acceleration function: When the load is below 30% of the rated value, the operating speed is automatically increased to improve work efficiency.
Industrial bus support: Compatible with protocols such as Profibus, Profinet, EtherCAT, etc., it can seamlessly integrate with PLCs, HMIs, and sensors to achieve remote monitoring and fault diagnosis.
Power matching: The rated power of the frequency converter should be ≥ 1.2 times the rated power of the motor (1.5 times for heavy-duty scenarios).
Open loop vector: suitable for general lifting scenarios, with low cost.
Closed loop vector: requires encoder feedback, suitable for high-precision positioning (such as automated warehouses).
