Overview
The document discusses the Heavetronic® system, developed by Liebherr for deep sea operations, specifically for the RL-K Series of Ram Luffing Knuckle Boom Cranes. It integrates with the Liebherr Litronic control system to ensure safe lifting and lowering of loads, utilizing the Pactronic® Hybrid Drive to counteract sea motions.

Functional Principle
The system uses a motion reference unit (MRU) to monitor wave movements affecting the ship and crane. It predicts the vertical movement of the crane boom tip and automatically controls the winch to stabilize the load relative to the seabed.

Subsea Winch
The deep sea winch developed by Liebherr allows operations up to 3,600 meters below sea level. It includes a special rope reeling mechanism to minimize wear and extend rope life.

Advantages

• Improved efficiency in subsea lifting
• Controlled and safe load handling
• Minimized dynamic loads on the crane
• Integration with the Liebherr Litronic control system

Customer References
The document lists numerous offshore crane customers, including major companies like BP, Chevron, Exxon Mobil, and Shell, among others.
