Construction cranes are machines used to lift, lower and transport materials and equipment too heavy for a human to handle. They primarily employ pulleys and cables and allow for both vertical and horizontal movement. Construction cranes are extremely useful and have remained a valuable tool, especially for the construction industry.

Along with various electronic components, many construction cranes use levers and pulleys that direct and distribute the amount of weight needed to lift a particular object. Alternatively, hydraulic machinery is commonly used in today's preferential construction cranes, of which a liquid, specifically hydraulic fluid, acts as its means of power. During a lift, hydraulic fluid is pressurized according to the level of resistance present, and the fluid is controlled and distributed throughout the machine via hoses and tubes, bypassing the need for mechanical gears and levers. Also present are counterweights, which are movable concrete slabs that balance the load. They are located within the machinery arm, which also contains the crane's electronics and motors. The machinery arm is attached to one end of the jib, which is the horizontally inclined axis of the crane that carries the load via the trolley. The trolley moves in and out from the crane's center, at which point the slewing unit is normally positioned. The slewing unit contains the motor and gear that allows rotation; this can be moved up and down the mast with large hydraulic rams in the climbing frame. The mast is the vertical component of a construction crane's design, the base of which is typically bolted to a concrete foundation. The mast applies the appropriate height at which the construction crane needs to reach and can typically extend itself as needed.
