Abstract: A method for alerting an operator during linkage overload in a machine is disclosed. The method includes calculation of operational height of a payload carrier. Fluid pressure in one of a lift cylinder assembly and a tilt cylinder assembly is sensed and weight of a payload based on the fluid pressure is calculated. Maximum payload height based on the pressure of at least one of the lift cylinder assembly and the tilt cylinder assembly, is determined Based on the maximum payload height, a threshold payload height is determined and compared with an operational height of the payload carrier. When the operational height of the payload carrier is equal to or greater than the threshold payload height, at least one of a warning generation event and limiting raising of the lift cylinder assembly occurs.

Abstract: An electronic engine speed control system is used on a work machine utilizing an engine with a governor control movable between a plurality of positions. The governor control is operated by an operator so that a desired engine speed may be selected for driving a plurality of wheels through a transmission. The transmission is specifically controlled to obtain a desired ground speed independent of the selected engine speed. The engine speed control system includes an electronic control module. An operator switch is connected to the control module and is movable to a set position which sends an input signal with a desired engine speed value corresponding to a selected engine speed to the control module. An engine sensor is connectable between the engine and the control module for sensing the speed of the engine and sending an input signal with an actual engine speed value to the control module.

Abstract: A door frame assembly for a work machine includes a plurality of rectangular tubes, a plurality of zee shaped metal strips, and a plurality of resilient seals. The tubes are joined together to form a rectangular framework. Each metal strip is connected to one of the tubes and one of the seals is connected to a first leg portion of each of the strips. Each of the tubes and a second leg portion of each of the strips define a recess and a glass panel is adapted to rest within the recess and be bonded to the second leg portions. The door frame assembly is economical to manufacture and requires no expensive or complex forming tools.

Abstract: A non-metallic roof for a work machine includes a rotationally molded plastic structure which encloses and seals the top portion of an operator's station of the work machine. The roof includes grab rails and light sockets which are integrally molded into the structure. A plurality of metallic bars and cooperating threaded fasteners connect the roof to the operator's station. A closed cell foam material seals the juncture between the roof and the top portion of the operator's station.
