Vulco seismic isolators pass the test
Seismic isolation technology developed by Vulco was recently used in one of the largest ever experiments into how buildings react to earthquakes. Vulco seismic isolators are currently used in South America in high-rise residential buildings and civil infrastructure such as bridges and railways. The University of California-San Diego set
up the project. It used a specially constructed building, simulating a five-storey hospital and fully equipped with medical equipment, lifts and beds and mounted on a giant hydraulic table. The hydraulics enabled the tests to mimic recorded earthquakes around the world and the building was subjected to the stresses of an 8.8 Richter scale quake. The test used the seismic isolators to determine the difference between an isolated and non-isolated structure. The results were impressive, with the building which included four Vulco seismic isolators sustaining zero damage to its structure and contents during the 8.8 Richter test. When people re-entered the building to review the results, they even found glasses and bottles in the same location. Ricardo Abarca, product manager and new business for Weir Minerals Chile was involved in the project.
Successful nuclear power station outage delivered for EDF
A team of 80 people from Weir Power & Industrial’s Teesside and
Alloa service centres recently contributed significantly to a successful outage on Reactor 2 at Heysham 1 nuclear power station on the North West coast of England.

Dewatering expertise goes digital
Weir Minerals has launched a new website, ‘
DewateringExpertise.com’ that displays interactive graphics to illustrate which pumps are most appropriate for use in a wide range of mine and quarry applications. Available products include those for use
in underground mining, open- pit mining and quarrying in addition to extraction of water from lakes, rivers, ponds and the sea for use in wet processes. The website aims to assist
operators to quickly understand the most appropriate pump and process

equipment to suit their requirements. Brunella Stefanelli, regional marketing manager at Weir Minerals said: “Dewatering is a challenge that almost all quarry and mining operations have in common, but with so many different applications and a wide range of products available, it is not always easy to know which pump is appropriate for the job. A site operator can now log on to the new website and quickly learn which family of pump to use and also the specific models and sizes that are available.”
The work executed on the pumps was particularly challenging as it was necessary to complete these tasks within a tight timescale in order to avoid impacting upon subsequent critical outage tasks. All Weir permits were returned in line with the outage programme and EDF were very satisfied with Weir’s overall outage performance with commitment to HSEQ noted by EDF as being of a high standard. All audits were completed with no negative issues to report. The effort by Weir employees, both at the power station and at the service centres, was recognised by Heysham’s station management team “The culture that has developed on site is something to be proud of. The safety focus and personal ownership to get the job done is impressive. Team working, contract partner engagement and integration of the projects into the station organisation have contributed to the successful delivery of a tremendous amount of work and some really significant projects.”
