Monorail Bogie Maintenance Workstation

The Monorail Bogie Maintenance Workstations will be used to facilitate the inspection and service of components and subsystems associated with the bogie, including the replacement of rolling stock and maintenance vehicle guide tires and load tires. The Monorail Bogie Maintenance Workstations will also be used for the complete removal of the entire bogie assembly from the vehicle and for the return and reinstallation of a complete bogie assembly to a vehicle. It is a device that will:

  1. Provide support for the guide tires
  2. Provide support for the load tires
  3. Lift/lower the vehicle
  4. Support the bogie
  5. Provide release force on the guide tires to facilitate removal/replacement if such tires and/or the bogie
  6. Facilitate a means of extraction of the bogie and other bogie subsystems, including load and guide tires from under the vehicle via lateral motion/transfer.

The Monorail Bogie Maintenance Workstations are inserted into a monorail train concrete rail beam to facilitate the removal and installation of one or more monorail train bogies. 

Using a sophisticated control and user interface screen, operators can engage a single Monorail Bogie Maintenance Workstation to access a single bogie unit, or activate up to four Monorail Bogie Maintenance Workstation units to access bogies on two rail cars simultaneously.

These systems support the train car hydraulically to allow for detachment of the bogie(s) from the train car. Next, an electromechanical drive is engaged to lower the bogie and to traverse outward from the monorail beam, so that full surround access to the bogie is feasible. 

Operators can perform maintenance tasks on the bogie unit, or replace it entirely, by reversing the above process.

The Monorail Bogie Maintenance Workstation can be used individually or in synchronized mode. The synchronized mode is used by the operator during the “Bogie Removal” and “Bogie Installation” process.  Synchronized mode enables the lifts to travel in sync with each other.

Individual mode is used to move individual lifts with bogies sets that are detached from the car after the synchronized portion of the “Bogie Removal” process and before the synchronized portion of the “Bogie Installation” process.   

Manual Mode allows individual functions to be performed separately.
