What allows the hydraulic fluid to flow to the swing hydraulic motor?

The operation of a crane's swing mechanism relies on hydraulic fluid flowing to the swing hydraulic motor, enabling it to rotate the crane's upper structure. This fluid is managed through specific components in the hydraulic system, one of which is the swing cutout valves.

These valves play a critical role in controlling the flow of hydraulic fluid. When the crane operator engages the swing function, the swing cutout valves open to allow hydraulic fluid to pass through to the swing hydraulic motor. This ensures that the motor receives the necessary hydraulic pressure to operate effectively, controlling the rotation smoothly and accurately.

In contrast, other components such as hydraulic filters, hydraulic pumps, or control levers do not perform this specific function of directing fluid flow to the swing motor. Hydraulic filters are designed to remove impurities from the fluid, pumps generate the fluid flow, and control levers enable the operator to command various movements, but they do not directly facilitate the flow of hydraulic fluid to the swing motor in the same manner that the cutout valves do. This makes the swing cutout valves integral to the hydraulic swing operation.
