Lifting capacity systems and methods for lifting machines

A method for determining a lifting capacity of a lifting machine, the lifting machine including a chassis, a boom extending from the chassis, and a connector extending from the boom for coupling to a load, the method comprising:

• sensing information including one or more of:
• a boom overhang distance;
• or
• an orientation of the chassis;
• measuring a real-time load on the boom and/or on the connector;
• and
• displaying a rated lifting capacity and a lifting load on a display, wherein the rated lifting capacity is based on the sensed information, and wherein the lifting load is based on the measured real-time load on the boom and/or on the connector,
• wherein displaying the rated lifting capacity and the lifting load on the display includes displaying the lifting load relative to the rated lifting capacity on a common display bar.

A mobile pipelayer machine, comprising:

• a machine chassis;
• a boom extending from the machine chassis;
• a connector extending from the boom for coupling to a load;
• a control system that determines a rated lifting capacity of the mobile pipelayer machine and a lifting load, wherein the control system determines the rated lifting capacity based on an a fore, aft, and roll orientation of the machine chassis;
• and
• a display, wherein the display indicates:
• the rated lifting capacity relative to a total lifting capacity on a display bar,
• the lifting load relative to the rated lifting capacity and the total lifting capacity on the display bar,
• a numeric value of a current chassis pitch, and
• a numeric value of a current chassis roll.
