Product Description
Design to Order (DTO): Thanks to its international production facilities, which work closely with each other in the plant network, SEW-EURODRIVE is also able to build special gear units – worldwide, in its own production facilities, and specifically tailored to the customer's application.
Specification
Example: Hoist drive for a ladle crane
A four-stage differential gear unit is at work in the primary hoist of a 180-metric ton ladle crane. This powerful unit weighs a total of 15.8 metric tons and is driven by two motors, each with a power rating of 191 kilowatts. With the motor power installed, this drive achieves an operating torque of 225 000 Nm and a nominal gear unit torque of 500 000 Nm.
A special feature of this gear unit is the integrated planetary superposition stage, which safeguards the functionality of the hoist even if one of the motors fails. This ensures that the lifting process can still be completed at full torque at half the hoisting speed.
