Speed control for large cranes is a demanding task. Vacon India has supplied VACON® NXS and VACON® NXP drives for four Mukand cranes delivered to a foundry operated by Elgi, Asia's largest manufacturer of air compressors and automobile service station equipment.
Mukand Ltd. is the largest India-based designer and manufacturer of gantry cranes*, and an important OEM customer of Vacon India. Vacon India has supplied VACON NXP and VACON NXS drives in enclosures to control four Mukand cranes at the new Elgi foundry in Kinnathukadavu, Coimbatore in the southernmost part of the Indian Peninsula. Two of the cranes have a lifting capacity of 10 tons and two of 5 tons.
Very satisfied with the performance of the VACON® AC drives
Mukand had several reasons for choosing VACON AC drives. One of the most important reasons was that Vacon has dedicated application software for mechanical braking, which enables excellent speed accuracy and brake control in open and closed loop control in hoisting and long travel applications. The VACON AC drives are also user-friendly.
The VACON AC drives are able to set the critical parameters for the motor automatically during identification, thus providing improved control of the crane in hoisting, cross travel and long travel. The VACON AC drives enable accurate speed and torque control with the help of an internal speed and torque loop controller. The VACON AC drives also have a built-in line choke to limit line disturbances.
