Which Inverter Brand is Right for Your Tower Crane? Discover the Top 10

The selection of the right inverter for your tower crane is a critical decision that can significantly impact the efficiency, performance, and overall reliability of your equipment. Inverters play a pivotal role in controlling the speed and torque of electric motors, making them essential components in modern cranes.

This article will delve into the fundamental principles of inverter operation, introduce the top 10 inverter brands, and explore the key factors to consider when making a selection.

How Inverters Work？

Crane-specific inverters mainly work based on the variable frequency drive principle in power electronics. It converts the input fixed frequency and fixed voltage AC power into DC power through a rectifier, and then inverts the DC power into AC power with adjustable voltage and frequency through an inverter, which is supplied to the crane motor. Compared with the traditional speed regulation methods such as changing the number of pole pairs of the motor or using electromagnetic speed regulators, this method has higher precision and efficiency.

During the speed regulation process, the inverter can also realize soft start and soft stop functions. During the start-up, it gradually increases the output voltage and frequency, allowing the motor to accelerate smoothly from a stationary state to the set speed, avoiding the large current impact of direct starting and reducing the damage to the power grid and the motor itself.

Similarly, during the stop, the inverter slowly reduces the output, allowing the motor to gradually decelerate until it stops, preventing the load from shaking and impacting due to sudden stop, and improving the safety and stability of the operation.
