Abstract: A collapsible overhead guard for use with an industrial vehicle or the like may be easily lowered so as to accommodate vehicle operation in areas where low overhead clearance is encountered. The guard includes forward and rear telescoping support members joined by a substantially rectangular roof member. The front telescoping support members are rigidly fixed to the roof member and to the vehicle and include bearing mounted rollers to facilitate relative movement. The rear telescoping support members are pivotally connected to the roof member and to the vehicle so that the generally horizontal orientation of the roof member is maintained. Locking means including retractable pins on each support member are provided for retaining the collapsible overhead guard in a plurality of positions.
