🔍 Key Concepts

• Counterbalance (holding) valves in hydraulic winch circuits • How a mechanical brake or spring‑applied brake is released by hydraulic pressure • Which components are mounted directly at the drum or hoist motor to stop unintended motion

💭 Think About

• On the schematic, find the symbol that represents the wire rope drum or hoist; which numbered items are physically associated with that drum? • Among those nearby items, which one looks like a brake or holding device, and which one looks like a hydraulic valve controlling that brake? • Which pairs in the answer choices are located where they could actually lock the drum when no hydraulic pressure is applied?

✅ Before You Answer

• Verify which symbol represents a spring‑applied, hydraulically released brake (look for a spring symbol on a small actuator attached to the drum/motor). • Confirm which adjacent valve symbol is a counterbalance/holding valve, designed to stop flow and prevent overhauling when pressure is lost. • Make sure the components you choose are directly linked to the drum shaft, not just in the general supply line or boom cylinder circuit.
