发明名称 Excavation equipment alarm system
摘要 An excavation equipment alarm system for providing advance warning to an operator of an excavator of overhead obstacles. The excavation equipment alarm system generally includes a support member attached to the actuator, a guide tube attached to the support member, a guide arm slidably positioned within the guide tube, a mounting post attached to a distal end of a telescoping arm of the actuator and to the guide arm, and a magnetic sensor attached to the actuator to detect a distal end of guide arm. If the magnetic sensor detects the presence of the guide arm, then the warning unit is not activated. If the magnetic sensor no longer detects the presence of the guide arm, then the warning unit is activated to warn the operator of the excavator that the boom of the excavator may be at an unsafe height.
