Spider

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.
