The man-riding crane designed and approved for transferring personnel and cargo  

With Spider, technicians no longer need to climb the boat landing ladders to enter the transitions pieces (TPs), nor is it necessary to equip the TPs with separate lifting systems for personnel and cargo.

Designed with safety as the highest priority

Spider has all the advantages as the Titan-cranes and is further upgraded with e.g., electrical slew, UPS system and a secondary brake. The personnel is transferred in a basket designed and built to withstand impacts. And to increase the safety of the personnel, the basket is equipped with cameras connected to a wireless remote control with a display ensuring visual contact between the crane operator and the personnel, basket, and its surroundings.

Crew basket designed with safety in mind

Spider is co-developed with Reflex Marine and carefully designed and created based on many years of experience. The basket  went through rigorous testing, such as drop tests at 700m and full-scale immersion and self-righting tests. As such, it is designed for advanced passenger protection and represents a revolution in the crane transfer.
