Crane Design Details

West Alpha – Gantry Crane

The crane is a hydraulically operated gantry type crane, which travels on rails in the fwd/aft direction. It is designed to handle tubulars from the storage area on the pipedeck to the horizontal pipehandling system which conveys tubulars onto the drillfloor. The main beam is rigidly fixed to an A-frame leg in one end. The other end is pinned to an A-leg. Each leg is resting on a crane drive assembly (carriage). The crane drive assembly includes wheels, side rollers, rack pinion drive and anti-lift arrangements. more ...

Projects / References

We have been involved in Oil Industry Projects, and have designed Cranes for rough deepsea conditions. Therefore we are perfectly capable of designing Cranes for ordinary onshore conditions, including special loadings as – earthquake, which is very similar to offshore rig motion loading. more ...
