Abstract

A control system detects a loaded state for a lifting device. The control system receives a current load value from a load sensor corresponding to a load on the lifting device and compares the current load value from a previously received load value to determine a change in load. The control system receives a current displacement value from a displacement sensor corresponding to a displacement of the lifting device and compares the current displacement value with a previously received displacement value to determine a change in displacement. The control system compares the change in load with the change in displacement to determine a current load slope. The lifting device in identified in a loaded state based on a comparison of the current load slope with a load slope threshold. The control system may stop extending the lifting device after reaching the loaded state and start extending all of the lifting devices in unison to lift the load off of a base surface after all of the lifting devices reach the loaded state.
