Demag Cranes &
Components, has installed
a crane system at
Canterbury Cathedral’s
purpose-built 400m2 stone
saw shop.

The facility is operated
by the Cathedral’s inhouse
team of stone
masons. Ongoing
restoration and conservation work
currently involves the import of over
25 cubic metres of stone per year,
weighing almost 65t.

Raw stone scants are delivered to
the saw shop and offloaded by the
Demag crane which then loads
scants onto the saw, where they are
cut into smaller blocks. These are
transferred to the masonry workshop
for cutting.

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. It
is controlled by a mobile pendant,
which lets the operator position the
stone accurately on the saw.
