Y27 Lsi(f)-A

The bogie Y27 Lsi(f)-A is a variant of the standard railway wagon bogie Y27. When used in railway track machinery, the bogie is equipped with wheelsets gear units and hydrostatic motors.


As the Y27 does not have a buffer beam, it was possible to utilise the resultant free space for accommodating a powerful drive unit. The wheelsets can be braked on one side only, however.


To allow the bogie to be used at a maximum speed of 100 km/h permitted in terms of braking in the loaded condition, composite brake block holders have to be employed.

The bogie accommodates all components required for generation the braking force. The two double brake cylinder arranged under the cross-member are provided with built -in slack adjusters. An arresting brake can be fitted as an option.


At the end of the sole bars of the bogie, predrilled plates are provided, onto which special attachments such as rail guards can be fitted.


Manufacturing at ELH is carried out based on our own set of drawings.
