Man-Riding

Seasight Davits has added a new crane model to their product range, the Man-Riding crane, which is designed and approved for transferring personnel as well as cargo.
This means that the technicians no longer have 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.
The Man-Riding crane takes its point of departure in Seasight Davits’ existing cargo davit crane, the BM-crane with 4 meters outreach and 1000 kg. lifting capacity. In addition, it has been equipped with e.g., an electrical slew, a UPS system, a secondary brake as well as a wireless remote control with a display connected to cameras inside and outside of the personnel basket. This increases the safety of the personnel substantially as the crane operator has visual contact with the personnel as well as the basket and its surrounding avoiding collisions.
Seasight Davits’ cranes are well-known for their Plug and Play design, where all the key components are built into the crane house eliminating the need for disassembling the crane after the factory acceptance test (FAT), which makes the installation of the davit cranes substantially easier and cost effective. Additionally, having the key components protected against the harsh offshore environment, makes the cranes more reliable and increases their lifetime.
