Big gas springs check door movement at exposed site

摘要

Industrial Gas Springs (IGS) has provided large size dampers to control a set of doors on a storage bunker at an oil refinery situated on the coast of West Wales. Aker Kvaerner Engineering Services approached the company in August 2006 in the course of carrying out work at the site, with a view to finding the most efficient solution to a potential safety problem. Aker Kvaerner structural designer, David Nicholetts takes up the story: "I asked IGS to recommend a suitable gas spring or shock absorber for two fully-clad, 2m wide x 4m high doors. These needed to be able to take a wind load of 3kN when opening/closing. However, they were not required to assist in opening/closing operations or in restraining the leaves in their open/closed positions." Project engineer, Owen Derrick, sent IGS some initial drawings and dimensions for appraisal.
