What is a potential hazard when operating a truck mounted crane on rubber?

• A. Over the side at a minimum radius
• B. Maximum boom length
• C. Uneven ground surface
• D. Using a high boom angle

Answer: (A)

Operating a truck-mounted crane on rubber presents various hazards due to the interaction between the crane's weight, the stability of the rubber tires, and the surface conditions. When considering the option regarding operating over the side at a minimum radius, this is particularly hazardous because it can lead to tipping or instability. When the crane is extended over the side without adequate load capacity or stability, the risk of the crane's center of gravity shifting increases significantly, which can compromise the operator's safety and lead to accidents. The selection of a minimum radius is critical because it determines how much load is being placed on the crane's stabilizers and tires. At minimum radius, there is less support from the crane's structure to counterbalance the load, making it the most hazardous position for stability. Understanding the crane's load charts and limitations is essential to prevent dangerous situations like tipping or rolling over, especially when the crane is operated on less stable surfaces, such as those found in truck-mounted applications.
