The concept of drayage has its roots in the transportation of goods by horse-drawn wagons and carts. The term "dray" originally referred to a low, strong wagon or cart used for transporting heavy loads short distances. In the 19th century, drayage services were crucial in connecting ports to nearby warehouses, factories, and railways. It was a labor-intensive process that required the strength of draft animals and the determination of workers. The idea of using standardized containers for shipping cargo is much older than one might think. In the 18th century, wooden crates and barrels were commonplace for shipping, but their irregular sizes and shapes posed numerous challenges. It wasn't until the mid-20th century that the modern shipping container was born.
