ABSTRACT:
A latch mechanism for a tilting cab vehicle selectively secures a cab thereof to the vehicle frame in a lower use position against movement to an access position. The latch mechanism includes a keeper preferably mounted on the cab and a base preferably mounted on the frame. A keeper opening of the base receives the keeper upon movement of the cab to the use position. The mechanism also includes a bolt mounted on the base for movement between a latching and a nonlatching position so as to selectively engage and disengage the keeper within the keeper opening to maintain the cab in the use position. A hydraulic cylinder mounted on the base defines a cylinder bore and includes a piston slidable within the bore. A first side of the piston includes a connecting rod portion that fixedly mounts the bolt such that sliding of the piston moves the bolt between its two positions. A first end of a helical spring is seated against a cylinder end wall within the bore and a second end thereof is seated against the second side of the cylinder so as to bias the piston in a direction that moves the bolt to the latching position. Hydraulic fluid is supplied to the cylinder bore on the first side of the piston so that the fluid acts against the bias of the spring to move the piston such that the bolt is moved to the nonlatching position.
