muelles

Muelles is the Spanish plural form of muelle, and it can refer to two main concepts: mechanical springs and maritime piers (docks). In engineering, a muelle is a device that stores energy when deformed and returns it to the system when unloaded. Springs are used to absorb shocks, regulate motion, or apply force. Common types include helicoidal (coil) springs, leaf springs, and torsion springs. Key properties are stiffness (spring constant), elastic limit, fatigue life, and maximum operating load. Materials range from high-carbon steel and alloy steels to stainless steel, phosphor bronze, and polymers, selected for elasticity, corrosion resistance, and temperature behavior. Over time, spring performance is influenced by design, manufacturing quality, and operating environment.

In nautical and harbor contexts, muelle refers to a quay, pier, or wharf—an area where ships dock to load and unload cargo or passengers. Muelles are integrated with port facilities, including mooring systems, cranes, and access roads or rail links. Layout and depth considerations affect the types of vessels served and the efficiency of trade.

The term muelles also appears in geographic names and translations. In English, muelles is translated as springs or docks, depending on context. The word is used across Spanish-speaking regions and in technical documentation for both machine components and port infrastructure.
