ABSTRACT:
A device for securing a bogie at predetermined positions on a trailer hitched to a tractor, having a pair of spaced housings secured to a cross beam of the bogie and supporting a pair of pins adapted to secure the bogie to tracks on the trailer, the pins being tandemly controlled by a handle which is also coupled by an adjusting member to a control valve connected between a source of pressured air on the tractor and the brake system on the bogie. When the pins are in an engagement with the trailer, the control valve is actuated to release the bogie brake system. When the pins are not in engagement, the control valve is actuated to vent to atmosphere the pressurized air thereby leaving the brake system operative. A lock pin is used to secure the handle in the engaged position.
