Electrified Monorail System Drives for Heavy Loads


Electrified monorail systems are an important tried and tested means of transport for operationally reliable transportation of heavy loads – surely in your systems as well.
The range of electrified monorail system drives for heavy loads has a total of four sizes so that they are able to provide you with optimum support in this regard. Wheel loads of14 500 N to 40 000 N are implemented.
In this way, they ensure optimal matching of power, conveyor speed and lift capacity of the drives to your transported goods and your application.
The latest size, the HK37 bevel gear type, completes the lower power range with a permissible wheel load of up to14 500 N at a maximum torque of up to 220 Nm.


  • Four sizes ensure optimal matching of the conveying capacity, conveyor speed and lift capacity
  • High degree of efficiency of the helical-bevel gear unit (in comparison to a helical-worm gear unit)
  • Low maintenance required in connection with the contactless energy transfer MOVITRANS®
  • Can be switched safely thanks to coupling in the gear unit output stage
  • Impressive energy saving potential of motors in efficiency class IE2, IE3 or IE4
  • Reliable disk brakes for reproducible stopping accuracy
  • Only high-quality winding wires and insulating materials are used to ensure the inverter’s fault-free operation
  • Electrified monorail drives can be combined with many options from the range of modular systems offered by SEW-EURODRIVE
