摘要： 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.
