7 Benefits of Using Variable Frequency Inverter to Control Crane or Hoist

by Jackson William Blogger

No other technological development in nearly a few years has done more to revolutionize overhead crane operation and maintenance than VFD or inverter. Now, variable frequency inverter has become an industry standard for crane and hoist control.

In the material handling industry, variable frequency inverters are often used in electric hoists as well as in overhead cranes and lifting systems. There are some quality frequency inverter suppliers that provide high-quality products according to their customer requirements. It is also making the use of two-speed control using contractors and two-speed motor less practical. Variable frequency inverters are usually designed around a microprocessor that allows for the creation of programmable function for specific applications.

What are The Benefits of Using a Variable Frequency Inverter to Control Your Hoist or Crane?

Greater Speed Adjustment
Variable frequency inverter lets you choose from multiple speeds, permitting you to customize your hoist control to your application.
Improved Load Control
Putting a load using a single-speed hoist may cause shock loading or load swings. A variable frequency inverter allows for smooth operation by gradually slowing down a load and it also allows for smooth acceleration for preventing load swings in the traverse motions.
Duty Cycles
A variable frequency inverter is concisely matched with a braking resistor, depending on the duty cycle of the motion. A recovering drive can also be used that’s not dependent on the duty cycle.
Efficiency
A frequency inverter will only consume the power that’s needed, thus saving energy compared to contractors and soft-starters.
Increased Hoist Life
Some frequency inverter provides thermal overload and over current protection for the hoist motor, for prolonging its life. It also utilizes a ramp-down-to-stop method of braking rather than using brake shoes to slow down. And the brake is only used for parking and emergency situations that prolong its life.
Regenerative Energy
Deceleration and lowering of a hoist create recreating energy that’s produced by the motor. It can be malformed into heat using a braking resistor or conditioned and send back them to the source, so netting energy savings. And an AC regenerative drive will redistribute that energy, which would otherwise be wasted when converted to heat with a braking resistor.

Conclusion:

These are some benefits of using variable frequency inverter to control your crane or hoist. It is ideal to find the best frequency variable suppliers that manufacture and supply frequency inverter and other products according to their demand to meet their specific needs.
