🔍 Key Concepts

• Load-holding / counterbalance valves in hydraulic crane circuits • How a boom angle is maintained when hydraulic flow is stopped • Which symbol in the diagram represents a pilot-operated check or holding valve associated with the boom cylinder

💭 Think About

• Look at the components directly connected to the boom lift cylinder hydraulic lines. Which item is positioned to prevent the cylinder from drifting when the control valve is in neutral? • Which numbered item would still act to hold the boom in place even if there is a small internal leak past the directional control valve? • Compare items 1, 5, 6, and 18: which one is clearly designed as a safety or load‑holding device rather than as a control lever or simple line fitting?

✅ Before You Answer

• Verify which item number is shown in-line with the boom lift cylinder ports, not the swing or winch circuits. • Confirm that the symbol for the chosen item includes a check valve with pilot operation or pressure control feature, typical of load‑holding valves. • Make sure the item you select is described in your study materials as providing load holding / anti-drift protection rather than basic directional control.
