The Escort Hydra Crane Reduction Tube is a specific hydraulic component used in Escort-brand hydra cranes. The reduction tube manages and reduces the pressure of hydraulic fluid as it flows through the system. This is crucial for ensuring that the hydraulic pressure remains within safe and optimal levels for the crane's components. It controls the flow rate of hydraulic fluid to various parts of the crane, such as the boom, lifting mechanisms, and outriggers.
