At Texas Hydrostatics, we believe that understanding the benefits and features of hydraulic systems in cranes can help operators make informed decisions when selecting equipment for their lifting applications. Proper maintenance of hydraulic systems is also essential to ensure optimal performance and prevent downtime, and you can always contact Texas Hydrostatics with any questions or concerns about hydraulic systems in cranes.
Hydraulic systems are an integral part of crane operation, providing the power and control necessary to lift and move heavy loads. There are three main hydraulic systems found in cranes, each with its unique features and applications. In this blog, we will describe the three main hydraulic systems found in cranes and their respective functions.
Boom Hoist Hydraulic System
The boom hoist hydraulic system is responsible for lifting and lowering the crane’s boom. This system typically consists of a hydraulic pump, hydraulic cylinders, and control valves. The pump pressurizes hydraulic fluid, which is then sent to the cylinders to lift the boom. The control valves regulate the flow of hydraulic fluid, allowing for precise control of the boom’s movement.
Swing Hydraulic System
The swing hydraulic system allows the crane to rotate or swing the boom horizontally. It is typically composed of a hydraulic motor, hydraulic pump, and control valves. The hydraulic motor powers the crane’s rotation, while the pump pressurizes hydraulic fluid that is sent to the motor. The control valves regulate the flow of hydraulic fluid, allowing for precise control of the crane’s rotation.
Travel Hydraulic System
The travel hydraulic system is responsible for moving the crane from one location to another. It typically includes a hydraulic motor, hydraulic pump, and control valves. The hydraulic motor powers the crane’s movement, while the pump pressurizes hydraulic fluid that is sent to the motor. The control valves regulate the flow of hydraulic fluid, allowing for precise control of the crane’s speed and direction.
