Ensuring Safe Operation of Mobile Cranes

By Senior Chief Aviation Support Equipment Technician Joseph Hippolyte

Mobile cranes are essential in the U.S. Navy for completing critical maintenance tasks that require heavy lifting. However, these machines can pose many significant risks to personnel and equipment if not operated correctly or adequately maintained. In recent years, there have been several crane mishaps in the Navy, resulting in costly damage to aircraft and equipment and even fatal injuries to operators and bystanders.

One such mishaps occurred when a crane tipped over and caused significant damage to an aircraft. The investigation found the mishap was due to the crane lift evolution being performed on tires vice outriggers.

Another mishap occurred when the ship’s aircraft crash crane impacted the ship’s overhead structure during a maintenance test. The resulting impact caused minor damage to the crane and ship’s island structure above the crane. No personal injuries occurred. The Navy’s investigation revealed the test representative incorrectly raised the boom when the director gave the proper signal to lower the boom.

These incidents highlight the dangers in operating mobile cranes in the Navy. Crane mishaps can be caused by several factors, including negligent operation, improper maintenance, inadequate training and poor communication.

To prevent crane mishaps, the Navy has implemented several measures to ensure the safe operation of mobile cranes. Regular preventive maintenance and inspections are performed and safety training and education are provided to personnel. Proper site preparation and communication protocols are also established to combat mishaps while using mobile cranes. The Navy enforces strict regulations on mobile crane use, ensuring cranes are operated by qualified personnel and not used for tasks beyond their capacity.

Naval Safety Command (NAVSAFECOM), responsible for collecting and analyzing safety data to identify trends and hazards in Navy operations, works with Navy personnel to develop and implement safety policies and procedures to prevent accidents and to promote a culture of safety.

The Navy has also implemented new technology to enhance crane safety. For example, the Navy has started using cameras and sensors to monitor crane operation, detect potential hazards and provide real-time feedback to operators. The Navy is also exploring the use of robotics and automation in crane operation to minimize the risk of human error.

Although mobile cranes are critical for completing maintenance tasks in the Navy, they can pose significant risks if not operated correctly or adequately maintained. Crane mishaps can have costly consequences, including damage to equipment and injury – or even death. The Navy has implemented several measures to prevent crane mishaps, including regular maintenance and inspections, safety training and education, proper site preparation, and communication protocols. The Navy also enforces strict regulations on the use of mobile cranes and has implemented new technology to enhance crane safety. Through these efforts, the Navy aims to promote a culture of safety and prevent crane mishaps to protect our most valuable resource –our people.
