History of Lifting Equipment
Release date:
2024-01-18
In 10 BC, the ancient Roman architect Vitruvius described a lifting device in his architectural treatise. This apparatus featured a mast topped with a pulley; stay ropes secured the mast’s position, while a winch hauled a cable through the pulley to lift heavy loads. Some heavier‑duty machines employed two masts arranged in an A‑frame, enabling the suspended load to be moved laterally, though only over very limited distances, and requiring considerable physical effort to operate.
In 10 BC, the ancient Roman architect Vitruvius described a type of lifting device in his architectural treatise. This apparatus featured a mast topped with a pulley, secured in position by guy ropes, and operated via a winch that drew a cable through the pulley to hoist heavy loads. Some early heavy‑lifting machines employed two masts arranged in an A‑frame, allowing the load to be moved laterally—but only over very short distances, and with considerable effort. It was not until the 15th century, when Italy invented the jib crane, that this limitation was overcome. Such cranes incorporated an inclined boom fitted with a pulley at its tip, enabling both vertical lifting and horizontal rotation. Nevertheless, throughout the 18th century, all lifting machinery in use remained powered either by human or animal force, imposing severe constraints on lifting capacity, operational range, and efficiency. In the mid‑to‑late 18th century, following James Watt’s improvements and invention of the steam engine, a reliable power source became available for lifting equipment. In 1805, the engineer William Symington built the first steam‑powered cranes for London’s shipyards. By 1846, Britain’s Sir William Armstrong had converted a steam crane at the Newcastle shipyard into a hydraulically operated one. In the early 20th century, tower cranes began to be widely adopted across Europe.
