A retractable overhead guard assembly is provided to protect an operator of industrial trucks, such as a forklift operator, from falling objects. Said guard is retractable from a raised to a lowered position for operation in areas of low overhead clearance. A pair of substantially parallel extensible supports are attached to said truck. A guard is mounted on the upper ends of the supports and is manually slideable between a forward and rearward position and is maintained in either position by a locking mechanism. Said supports may include biasing means such as springs to counterbalance the weight of the guard and facilitate manual adjustment between raised and lowered positions. A locking mechanism is also provided on each support to retain the guard in a plurality of positions. Electrical interlocks prevent the raising of the lift beyond a predetermined height if the guard is not in the rearward and raised position where it offers maximum protection to the operator.
