System for monitoring load and angle for mobile lift device

A monitoring system for monitoring a force at a load moving device, the load moving device comprising an extendable boom supported by a structure, the load moving device configured to use at least one cable attached to a load to move the load, the monitoring system comprising:

• a first angle sensor configured to generate a first angle signal representative of a first angle of the cable relative to the load moving device;
• a second angle sensor configured to generate a second angle signal representative of a second angle of the cable relative to the load moving device;
• a monitoring circuit coupled to the first angle sensor and the second angle sensor to generate a force signal representative of at least one force being applied to the load moving device based upon the first angle signal and the second angle signal;
• and
• at least one length sensor coupled to the monitoring circuit and configured to generate an extension signal representative of the extension of the boom, such that the force signal is generated by the monitoring circuit based upon the extension signal and a load signal.
