Abstract
A backhoe loader includes a tractor-type vehicle with an operator station enclosed in a cab. Access to the cab is provided through a pair of front doors that are respectively disposed on opposite sides of the tractor hood, the upper portion of the doors also forming the front windshield of the cab. The major portion of the doors is formed by curved window glass, and each door includes a rigid metal frame that substantially conforms to the door opening. The door is made by placing the metal frame in a mold and encapsulating the frame in a polyurethane material that is molded around the metal frame by a reaction injection molding process. The door hinges and the latching mechanism are attached to the metal frame, while the molded polyurethane supports the window glass.
