Which piece(s) of equipment is/are required to "twin-up" 30-ton pedestal cranes aboard a crane vessel?

🔍 Key Concepts

• What it means to "twin‑up" pedestal cranes on a crane vessel • How loads are shared safely between two cranes working together • Which rigging or devices are designed specifically for equalizing load between lifting points

💭 Think About

• Think about which option(s) are actually used to connect and share one load between two cranes, not just to lift ordinary cargo. • Ask yourself: if two cranes are side‑by‑side lifting the same heavy load, what must be in place so that one crane is not overloaded if the load shifts? • Consider which listed items are general cargo‑handling devices versus those designed to balance or equalize load between lifting points.

✅ Before You Answer

• Identify which device is specifically meant to equalize load between multiple lifting points. • Decide whether a container spreader is intended for one crane or for coordinating two cranes together. • Consider whether a portable power swivel has anything to do with load sharing between cranes or if it serves a different function (e.g., rotating or powering a single line).
