Optimize Your Operations with Inverter Control Panel for Precise Speed Control
1. Highly Compatible Power and Capacity
Motor Power Adaptability: 25-ton cranes (especially the main hoist mechanism) require significant drive power. The core components of the inverter cabinet (inverter, brake unit, contactor, circuit breaker, etc.) must be precisely matched to the motor power (main hoist motors typically range from 55kW to 75kW or higher, depending on the hoisting speed and duty cycle).
Heavy-Duty Design: The inverter (especially the hoisting inverter) must be capable of heavy-duty applications (high overload torque, such as 150%-180% rated torque for 60 seconds) to ensure reliability and safety during heavy-load starting, sudden loading, or emergency braking.
Strong Heat Dissipation: High-power components generate significant heat, making the cabinet's internal heat dissipation system (such as high-power fans, ductwork, and possibly even rooftop air conditioning) crucial to ensure temperature rise remains within acceptable limits during continuous or frequent operation.
2. Extremely High Control Requirements for Hoisting Mechanisms (Core Focus)
Closed-loop vector control is standard: The main hoisting mechanism of a 25-ton crane must utilize a closed-loop vector control inverter with encoder feedback. This is the foundation for the following key functions:
Zero-Speed Full Torque Hold: When a heavy load (25 tons) is suspended in mid-air, the motor can output sufficient torque (100% rated torque or higher) to prevent the hook from slipping, eliminating the need for prolonged mechanical brake engagement (only for final hold), significantly reducing the risk of brake wear and heat.
Low-Speed High Torque: For precise positioning and inching operations, high torque (>150% rated torque) can be stably output even at extremely low speeds (e.g., <1% rated speed), ensuring smooth and precise movement of heavy loads.
Fast Dynamic Response: Rapid response to speed commands and load changes ensures smooth and safe operation.
