SYSTEM FOR MONITORING LOAD AND ANGLE FOR MOBILE LIFT DEVICE
First Claim
1. A monitoring system for monitoring a force at a load moving device which uses at least one cable attached to a load to lift or slide the load, the 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; and
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 at least one of the first angle signal and the second angle signal.

Abstract
A mobile lift device having a load moving device capable of engaging a load is provided. The mobile lift device includes one or more systems for stabilizing the mobile lift device during operation of the load moving device. According to one exemplary embodiment, the mobile lift device is a heavy duty wrecker having a rotatable boom assembly. The heavy duty wrecker comprises a monitoring system for stabilizing the wrecker during operation of the boom assembly. The monitoring system comprises a plurality of sensors and a monitoring circuit coupled to the sensors to generate a force signal representative of at least one force being applied to the wrecker based upon the transmitted signals.
