Overhead cranes, like any piece of heavy machinery, can be dangerous if not operated correctly. While every work site has its own safety guidelines and protocols, it’s essential to proactively prevent accidents by adhering to the best practices and safety mechanisms in place. Unfortunately, overconfidence among overhead crane operators or site supervisors can sometimes lead to a disregard for these vital safety measures.
Here are three common myths about overhead crane operation that can cause significant damage to equipment and, more importantly, pose a real threat to safety. While these myths may seem logical or like common sense, they are often a leading cause of accidents in workplaces. By being aware of them, you can ensure a safer work environment and safeguard both your equipment and personnel.
Myth 1: “Don’t worry about overloading, the crane has a safety factor.”
This is one of the most prevalent misconceptions about overhead cranes and has led to many accidents over the years. While it’s true that cranes are designed with a safety margin to handle loads within their rated capacity, this doesn’t mean it’s safe to exceed the maximum load. Overloading the crane can result in catastrophic damage, including structural failure or tipping, and is one of the primary causes of crane accidents. Always adhere to the crane’s rated load capacity to ensure safe operation.
Myth 2: “To reach the height, just lift the crane until it hits the upper limit switch.”
Many operators mistakenly believe that lifting the crane until it reaches the upper limit switch is the proper way to achieve maximum height. In reality, the upper limit switch is there to prevent the hook assembly from colliding with the drum, not as a means of determining the crane’s lifting limit. If the crane is lifted too high, the hook block can strike the drum, which could cause the load to drop, endangering both the equipment and personnel. It’s crucial to understand the actual limits of your crane and avoid overreaching by using the correct lifting techniques.
Myth 3: “All hoists have secondary brakes, so it’s safe to work under a load.”
While it’s true that most hoists are equipped with both primary and secondary brakes, it’s still unsafe to work under a load. The secondary brakes are designed as a backup to the primary brakes, but they may not always be able to handle the load, especially under extreme conditions or if the crane has been improperly maintained. Working under a load puts workers at serious risk should the braking system fail. It’s essential to always follow safety protocols and never position yourself under a load, even if secondary brakes are in place.
Responsibility for Safety
As the owner or supervisor of the facility, it’s your responsibility to ensure that all workers, operators, and site personnel are fully informed of these myths and the proper safety procedures. Clear communication and consistent emphasis on following safety guidelines are essential to maintaining a safe working environment. Regular training, safety drills, and inspections should be conducted to reinforce these practices and prevent accidents.
In conclusion, while cranes are vital equipment in many industries, they come with inherent risks if not operated properly. By busting these common myths and adhering to safety protocols, you can significantly reduce the risk of accidents and protect your team and equipment. Always prioritise safety and ensure that all staff are educated on the proper use of overhead cranes.
