Bucket elevator

Bucket elevators require high drive power depending on the bulk material and the conveyor height. Our standardized drive solution ensures that you have the power you need.

Powerful drive solution for bucket elevators

Standardized industrial gear unit solution for use in bucket elevators
Bucket elevators require robust gear units with a high power rating.
Bucket elevators require robust gear units with a high power rating.

Bucket elevators are conveyor systems that transport large quantities of bulk material vertically upwards. This requires high drive power that depends on the bucket's capacity and the relevant conveyor height.

It means that all the system components must be able to deal with the harsh and difficult operating conditions. A high level of reliability and availability of the components is also important in order to keep idling times to a minimum.

Auxiliary drive for slow movements

Our robust and high-torque drive solutions impressively meet the demanding requirements for bucket elevators:

  • Our bucket elevator drives are durable power packages with a wide gear ratio and high torques thanks to our X series bevel-helical gear unit.
  • The standardized application solutions mean that you benefit from rapid availability due to the modular design provided by SEW-EURODRIVE.
  • Take advantage of our global installation and service network for industrial gear units and increase your process reliability.
  • Combine a customized drive solution with the benefit of increased availability - regardless of whether your activities relate to the construction industry, the raw materials industry or the chemical industry.

Tailored to bucket elevators: SEW-EURODRIVE industrial gear unit solution

In some instances the bucket elevator is only allowed to operate at a reduced speed, such as during maintenance. That's why our bucket elevator drive has a directly mounted auxiliary drive from our modular system. It ensures that the necessary slow movement is provided when the main motor is shut down.

This auxiliary drive is available in the "empty bucket" or "full bucket" designs. All the components in our application solution are perfectly adapted to the relevant application.
