Abstract
A door operating mechanism for a cab door of a material handling implement is disclosed which includes a hold-open latch arrangement for conveniently maintaining the door in a partially open position. The operating mechanism includes a selectively operable door latch mechanism mounted on the cab door which cooperates with a latch pin mounted on the cab frame for releasably maintaining the cab door in a closed position. The hold-open latch of the mechanism is pivotally mounted on the cab door for movement between active and inactive positions, whereby in the active position thereof the hold-open latch is releasably engageable with the frame-mounted latch pin. By this construction, the hold-open latch and latch pin can be positioned in cooperating engagement with each other whereby the cab door is maintained in a partially open position. Very effective ventilation of the operator's cab is provided when the door is in its partially open position, thus avoiding the need for relatively complex and expensive movable window assemblies or the like in the cab door construction.
