Abstract

A virtual hoist stop system for a mobile drilling machine may include a sensor assembly configured to monitor a full/empty status of a plurality of pipe storage slots, a drill string status, and a height of a rotary head, an operator interface configured to receive hoisting input, and a control module. The control module may be configured to receive signals from the sensor assembly, determine a target height based on the signals, receive hoisting input from the operator interface, and automatically stop the rotary head from hoisting beyond the target height.
