Abstract
A load moment indicator system for lift equipment, the system including a sensor embedded in a solid portion of the piston rod of the lifting cylinder of the equipment for generating a signal which is indicative of the load being lifted. A stored value representing the maximum load lifting capacity of the lift equipment for a particular load zone is then compared to the actual load signal, and where the actual load approaches or exceeds the maximum load lifting capacity, alarm signals are activated and/or the operating functions creating the overload incapacitated.
