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: Work machines having linkages may need to have the linkage assembly locked in a predetermined position to prevent damage to an implement attached to the work machine, to prevent tipping of the work machine, to operate the implement, or other reasons. Locking the linkage assembly, however, can create significant loads on the linkage assembly. The disclosed method and apparatus is for a work machine that comprises a chassis, at least one linkage assembly attached to the work machine, at least one restraint having a first-end portion and a second-end portion, the second-end portion being attached to the chassis and the first-end portion being attached to the linkage assembly, the restraint transferring a load from the linkage assembly to the chassis.
