Can hydraulic fittings be used in crane equipment?

Hydraulic fittings not only can be used in crane equipment, but also occupy an extremely critical position in modern cranes. Hydraulic technology is an important driving force for lifting equipment to achieve functions such as heavy-duty lifting, amplitude adjustment, rotation, and extension. The hydraulic system relies on various hydraulic fittings working together to complete power transmission and control, so hydraulic fittings can be said to be a combination of the "nervous system" and "muscle" system of crane equipment.

During the operation of a crane, precise and powerful force is required to lift and move heavy objects. Traditional mechanical transmission methods have limitations in terms of structural complexity, adjustment flexibility, and control accuracy, while hydraulic systems can provide controllable and powerful power output in relatively compact spaces, which is exactly where hydraulic fittings shine in lifting equipment. For example, hydraulic pumps are responsible for converting the mechanical energy of the engine into the pressure energy of the liquid, providing a source of power; Hydraulic cylinders and hydraulic motors serve as executing fittings to achieve actions such as lifting, variable amplitude, and rotation of the boom; Hydraulic valve groups (such as directional valves, relief valves, balance valves, etc.) are responsible for directing the direction, pressure, and speed of oil flow, thereby achieving control of actions and protecting system safety.

Cranes need to frequently change their operating states during work, such as transitioning from lifting to lowering, from stationary to moving. This requires hydraulic fittings not only to transmit power, but also to have characteristics such as rapid response, smooth movement, and strong adjustability. For example, precision hydraulic control fittings such as proportional valves and servo valves can finely adjust flow and pressure based on input electrical signals, achieving flexible control of boom movements and greatly improving the safety and accuracy of operations.
When working at heights or on uneven terrain, the hydraulic leg system can quickly and stably extend and retract support through hydraulic cylinders, ensuring the stability and safety of the entire vehicle during lifting. This series of actions relies almost entirely on hydraulic fittings to achieve efficient linkage.
