History of Construction Equipment
The history of construction equipment is a long and fascinating one. The ancient Roman engineer Vitruvius described heavy equipment and cranes in his treatise De architectura.
The first pile driver was invented around 1500, which marked a significant milestone in the development of heavy equipment. Container cranes were used from the 1950s and onwards, making containerization possible.
In the 19th century, heavy machines were drawn under human or animal power. With the advent of portable steam-powered engines, the drawn machine precursors were reconfigured with the new engines.
The first commercial continuous track vehicle was the 1901 Lombard Steam Log Hauler, which paved the way for the use of tracks in civilian machinery like the bulldozer. The largest engineering vehicles and mobile land machines are bucket-wheel excavators, built since the 1920s.
The hand shovel was the primary earthmoving machine until almost the twentieth century. Builders have long used labor-saving devices like inclined planes, levers, and pulleys to place solid building materials.
