Crane Hoist Soft Starter

Owing to a state-of-the-art manufacturing facility equipped with ultramodern CAD/ CAM technologies, we provide buyers with energy efficient Crane Hoist Soft Starters. Designed to be compact, the starters are highly productive with long service life. We offer them in bulk. Buyers can come to us with request of customizations, as we can manufacture the starters as per technical specifications provided to us.

More Information

  • Starts motor in full load less than 1.5 times of motor full load current with a duty cycle up to 600 starts per/hr .
  • Steps less reduced voltage start which ensures a constant low starting current and incremental voltage and torque to the motor to get smooth acceleration.
  • As the motor speed increases, the controller impedance decreases due to counter EMF feedback to achieve constant incremental voltage torque for motor.
  • This achieves very soft and smooth starting of load to Crane hoist since the starting of motor in full load takes only less than 1.5 times of motor full load current.
  • This helps in optimizing the power source i.e., transformer or generator capacity. Optimized power system also gives savings in capital, cost savings and revenue expenditure due to higher efficiency.
