If a mineral water factory is transporting square-shaped plastic buckets of 1 meter in size filled with mineral water, which loading capacity is most suitable for stackers?

Choosing a loading capacity of 1500㎏ for transporting square-shaped plastic buckets filled with mineral water in a factory setting aligns well with practical logistical considerations. Each bucket, being square and 1 meter in size, can be assumed to hold about 1 cubic meter of water, which equals approximately 1000 kilograms in weight, considering the density of water.

In practice, stackers need to account not only for the weight of the water but also for the weight of the plastic buckets themselves and any potential safety margins to ensure compliance with regulations or to account for varying packing efficiency. For example, if a standard bucket weighs around 10-15 kilograms, and with the contents of water its total weight comes close to 1010-1015 kilograms for one full bucket.

Additionally, considering that stackers often operate with some allowance for extra capacity to prevent exceeding the rated limits under dynamic conditions, a loading capacity of 1500㎏ is a sensible choice. This provides sufficient margin to safely handle multiple buckets at once without risking overload, thereby ensuring safe operation and compliance with safety standards.

The other options may not be suitable as they either fall short of advisable capacity or exceed what's practical for handling typical loads safely in an industrial environment like a
