What do most crane manufacturers prohibit from being added to the crane?

Most crane manufacturers prohibit tool boxes from being added to the crane mainly due to safety and stability concerns. Tool boxes can add additional weight and change the center of gravity of the crane, which might lead to an imbalance and increase the risk of tipping over during operations. The design of cranes is specifically calculated to ensure optimal performance under safe load limits. Adding external modifications, such as tool boxes, could interfere with these calculations and the overall structural integrity of the crane.

Additionally, any unauthorized modifications can void warranties and may not comply with safety regulations. Manufacturers provide specific configurations and accessories that are designed and tested to work with their equipment, ensuring that safety standards are met. Therefore, adhering to these manufacturer guidelines is crucial for maintaining a safe working environment when operating a crane.
