Description

Technical Field

[0001] This utility model belongs to the field of shipbuilding technology, and specifically relates to a lifting device for a roll-on / roll-off ship radar. Background Technology

[0002] Car carriers are a special type of ship in the shipping industry, specifically designed for the transportation of various vehicles. With the increasing demand for car transportation, the number of car carriers has increased from the initial thousands to tens of thousands, and their height has also gradually increased to over 40 meters to meet the growing demand.

[0003] Against this backdrop, height restrictions imposed by bridges in various countries along different shipping routes result in excessive height requirements for exposed equipment on roll-on / roll-off (Ro-Ro) ships, especially radar equipment. This is because radar equipment typically has specific height requirements for different frequency bands to avoid signal interference, preventing ships from passing under height-restricted bridges to reach cargo ports. Furthermore, during navigation, the radar needs to be at a specific height to receive signals from the sea, and its supporting hydraulic cylinders are constantly in operation. The radar's rotation and adverse sea conditions can damage the hydraulic cylinders. Therefore, an auxiliary lifting and fixing device for Ro-Ro ship radar is essential. Utility Model Content
