Demag's Canterbury Tale
April 1st 2011 Lifting equipment manufacturer,
Demag Cranes & Components, has
installed a crane system at
Canterbury Cathedral's new purpose
built 400m2 stone saw shop on the
outskirts of the city, which is
operated by the Cathedral's in house
team of stonemasons.
Raw stone scants are delivered to
the stone saw shop and offloaded by
the Demag crane. The crane is then
used to load scants on to the saw,
where they are cut into smaller block
sizes. The blocks are transferred to
the masonry workshop, within the
Cathedral's grounds, for precision
cutting and carving by skilled
technicians.
To meet the specific needs of the
stone processing operation, Demag
supplied an 18.25m span overhead
travelling crane, rated at 10t SWL.
Mounted on the crane is a 10t SWL
Demag DR-COM electric wire rope
hoist. The system has long travel
speeds of 20/5m/min, cross travel
speeds of 5 to 20m/min and lifting
speeds of 4.0/0.7m/min. The system
is controlled by a mobile pendant,
which allows the operator to position
the stone accurately on the saw for
precision cutting, maximising yield
and reducing wastage of the
expensive raw material. More articles from Demag Cranes & Components Ltd: |
