Abstract: A thrust reverser actuation system is provided that includes a synchronization system that synchronizes the actuation of at least two actuators coupled to at least two power drive units. The synchronization system includes a first synchronization shaft coupling the first power drive unit to the second power drive unit and a second synchronization shaft coupling the first power drive unit to the second power drive unit. The at least two actuators are adapted to receive a drive force and configured, in response to receipt of the drive force, to move between a stowed position and a deployed position. The synchronization system is configured to transfer power between the first power drive unit and the second power drive unit, thereby eliminating a mismatch in power and provide uniform deployment of the at least two actuators.

Abstract: A controller (10) for the traction motor of an industrial truck comprises an actuator spool (56) which is axially shiftable by a manual selector member (12) for actuating a plurality of control switches (44,46,48). Detent means (86,78,82,84) hold the spool in forward, reverse or park positions and a return spring (66) urges the spool toward neutral position. The actuator spool (56) is adapted for rotational movement about its axis for automatic release of the detent means and return of the spool to neutral position. A seat occupancy detector (18) is actuated when the driver leaves the seat and imparts rotational movement to the spool which releases the detent means and returns the spool to neutral. The controller is also adapted to provide manual and automatic control of a parking brake (6). When the selector member is in the park position, cam means (184) on the actuator spool actuates a control switch (48) to apply the vehicle brake.
