Frequency Inverters for Cranes: Overhead, Tower

Frequency Inverters for Cranes: Precise Control and Smooth Operation

A crane frequency inverter is an electronic device that converts the AC mains voltage with a fixed frequency of 50/60 Hz into a voltage with adjustable frequency and amplitude, allowing precise regulation of the crane motor's rotation speed.

Why do you need a frequency inverter for a crane?

The use of a crane frequency inverter has a number of advantages:

• Smooth speed control: The inverter ensures smooth start, stop, and speed change of the crane, increasing load positioning accuracy and reducing the risk of damage.
• Energy saving: The inverter helps optimise the energy consumption of the electric motor, leading to significant electricity savings, especially when working with variable loads.
• Reduced wear and tear: The inverter reduces mechanical wear of the crane since smooth starting and stopping prevent sudden jolts. This extends the crane's service life and lowers repair costs.
• Increased safety: The inverter provides more precise crane control, enhancing the safety of the crane operator and staff.
• Additional functions: The inverter may include additional features such as overload protection, anti-collision braking, torque limitation, work mode programming, etc.

Where to buy a frequency inverter for an overhead or tower crane?

Frequency inverters for overhead (gantry) and tower cranes can be purchased at the Specialist store. When choosing an inverter, it is necessary to consider the crane motor's power, type of control, additional functions, and other parameters.

Benefits of using a frequency inverter for a crane:

• Increased productivity: The inverter allows the crane to operate more efficiently, increasing the speed of operations and lifting capacity.
• Noise reduction: The inverter reduces the noise level produced by the crane, improving working conditions for the crane operator.
• Increased lifespan: The inverter extends the crane's lifespan by reducing mechanical wear and tear.

The application of a crane frequency inverter is an effective way to increase performance, safety, and reliability of the crane, while also reducing operational costs.
