🔍 Key Concepts

• Trace the hydraulic lines connected to component #18 and note which major crane function (boom, winch, or swivel) they lead to. • Identify the symbol used at #18 (spring + ball/check + arrow) and recall what type of valve that represents in hydraulic diagrams. • Think about why you would need a safety or control device specifically on the boom cylinder side of the circuit.

💭 Think About

• Which actuator (boom cylinder, winch motor, or slewing motor) would be directly affected if #18 opened or changed setting? • If the boom were overloaded or a hose failed, what kind of valve action would protect the structure and prevent uncontrolled movement? • How would the crane behave when lowering a heavy boom load if this valve were not installed?

✅ Before You Answer

• Verify whether #18 is located in the pressure line, return line, or directly at the boom cylinder port. • Confirm the symbol details: does #18 look like a relief valve, a counterbalance valve, or a flow-control valve? • Check whether any other components in the circuit already control lowering speed or swivel speed so you don’t assign duplicate functions.
