Hoisting machinery is designed to lift and move heavy loads using a lifting hook or other attachment devices. The typical operation of such equipment involves several key steps: lifting the load, moving it horizontally, lowering it to the desired location, and returning to the original position. The hoisting mechanism is responsible for raising the object from its initial point, while the traveling, slewing, or luffing mechanisms help shift the load to the designated area. Once placed, the crane returns to its starting point, completing the cycle. Drive Unit The drive unit is an essential component that powers the working mechanisms of the crane. Common types of drive systems include electric drives, internal combustion engine drives, and manual drives. Electric drives are widely used in modern cranes due to their efficiency, environmental friendliness, and ease of control. Most cranes operating within limited areas—such as rail-mounted cranes, elevators, and overhead cranes—are powered by electricity. For mobile cranes that travel over long distances, like truck cranes, tire cranes, and crawler cranes, internal combustion engines are more common. Manual drives, though less powerful, are suitable for small lifting tools and can serve as backup or emergency power sources in certain situations. Working Mechanisms The working mechanisms of a crane consist of four main components: the hoisting mechanism, the traveling mechanism, the luffing mechanism, and the rotating mechanism. These are collectively known as the four major systems of a crane. (1) The hoisting mechanism is responsible for lifting and lowering materials vertically. It is a fundamental and indispensable part of any crane, especially gantry cranes, where it plays a critical role in material handling. (2) The traveling mechanism enables the crane or lifting trolley to move along a path. It allows both track-based and trackless operations and can be either self-propelled or towed, depending on the design and application. (3) The luffing mechanism is unique to boom-type cranes. It adjusts the angle and length of the boom to change the working radius, allowing the crane to reach different areas efficiently. (4) The rotating mechanism allows the boom to pivot around the vertical axis of the crane, enabling the movement of materials within a circular space. By using one or a combination of these mechanisms, cranes can effectively transport and place heavy objects with precision and control.
