Crane overturning is a serious and dangerous incident where the crane loses stability and tips over. This can result in severe damage to property, injury to personnel, and even fatalities. Crane overturning usually occurs due to a combination of factors, including improper load handling, equipment failure, environmental conditions, or operational errors. Causes of Crane Overturning: 1. Overloading. Exceeding the crane’s lifting capacity is one of the leading causes of overturning. When the load is too heavy, the crane can become unbalanced and tip over, especially if the weight distribution is uneven. 2. Improper Outrigger Setup. Outriggers help stabilize mobile cranes during lifting operations. If outriggers are not properly deployed or set on unstable ground (e.g., soft soil), the crane can lose stability and overturn. 3. Lifting on Uneven Ground. Operating on sloped or uneven surfaces can cause the crane to tip over as it compromises the crane's balance. 4. Swinging Loads. If the load swings excessively, particularly in high winds or due to rapid crane movement, it can cause a shift in the crane's center of gravity, leading to instability and a potential overturn. 5. Boom Mismanagement. Extending the boom too far without adjusting for the load or ground conditions can make the crane top-heavy and prone to tipping. 6. Wind or Weather Conditions: Strong winds can apply significant force to the load or the crane itself, increasing the risk of tipping. Heavy rain or soft ground can also weaken the foundation under the crane’s base. 7. Improper Load Distribution: If the load is not properly centered or secured, uneven weight distribution can shift the center of gravity and cause the crane to overturn. 8. Mechanical Failure: Malfunctioning parts like brakes, ropes, or hydraulics can lead to a loss of control, potentially resulting in an overturning accident. Preventive Measures: 1. Pre-Lift Planning. Careful planning, including understanding load weights, wind conditions, and ground stability, is crucial in preventing overturning. 2. Proper Use of Outriggers. 3. Load Monitoring. 4. Ground Conditions Assessment. 5. Wind and Weather Monitoring. 6. Training and Certification. 7. Regular Inspections and Maintenance. 8. Gradual Lifting and Movement. #LiftingOperations #Crane #SafetyFirst
pretty nasty fall for the two crash test dummies on the outrigger!!
Why did they not jump from crane before it fell off ?

1moDid the two guys on the outrigger think they would stay on `for the ride`. they didn't seem to be worried they were about to be `slung`
