Abstract: A lift truck cab having front, side, and rear faces, and a roof, mounting structure attached to the roof for suspending the cab from a mast of the lift truck in a manner that permits the front and side faces when installed on the truck to be hung in the manner of curtains without the necessity of direct fastening of lower portions of the front and side faces to the chassis/body of the truck. The cab construction affords generous operator space, high visibility, a convenient electrical raceway and ready access to truck control circuitry.

Abstract: A system, particularly suited for after market applications, for enclosing an overhead guard with window and prehung door assemblies. The window and door assemblies are arranged with portions that overlie outer surfaces of the guard and portions engageable with inner surfaces of the guard to retain the respective assemblies in place on the guard. The retaining structure of each of the assemblies extends through original vision or ingress/egress openings in the guard so that installation is simplified and structural alteration of the guard is avoided.

Abstract: A set of panel assemblies for enclosing the overhead guard of a vehicle such as a skid steer comprising a windshield/door assembly and side window assemblies. The windshield/door assembly includes a door jamb that is clamped over the front corner posts of the overhead guard and a windshield/door unit hinged on the jamb. The windshield/door unit seals against a generally planar front face of the jamb. The side window assemblies comprise transparent rigid plastic sheets adapted to be attached to the side grille of the overhead guard in a simplified manner and without occupying excessive space in the clearance area between the overhead guard and operating elements such as the lift arms of a bucket.

Abstract: An overhead guard for a vehicle, in the form of a cab for a lift truck, that affords both protection and a high degree of overhead visibility with a relatively open grille work of steel bar and an impact-resistant glazing sheet. The glazing sheet is sandwiched between a rigid framework and a sheet metal panel having a large cutout for the overhead view. Gusset plates reinforce the corners of the framework and provide convenient mounting locations for an air circulating fan. Threshold adaptor brackets are mounted in step pockets of the vehicle chassis to simplify the door structure while permitting the cab to be effectively sealed from the environment when the doors are closed.

Abstract: Cab panel structures and methods for their assembly on an overhead guard of a land vehicle. A metal roof panel can be used alone or with a metal frame windshield panel for a partial enclosure. The metal roof and windshield panels can be used with complimentary fabric panels that afford a full enclosure or with complimentary steel panels that afford a full enclosure of high durability. The metal panels are attached to the overhead guard posts in a unique clamp-on method that avoids the need for direct fastening of the guard and, accordingly, allows rapid installation.
