A Cat 6090 FS shovel loads a Cat 797F ultra-truck at the Moatize coal mine in Mozambique.
caters for mining’s super-pits
conditions. The fact that they are available in
both Face Shovel (excluding the 6090, which is
FS only) and Back Hoe configuration, as well as
electric or diesel drive, adds to their ability to
work in a variety of mining applications.
The biggest model in the range is the 6090
FS, which is the world’s largest hydraulic min-
ing face shovel, with an operating weight of
980 tonnes, an engine output of 3 360 kW and
a payload of 94 tonnes. The 6090 FS is said to
be the only shovel capable of four-pass loading
of 360-tonne haulers such as the Cat 797F. Only
one has thus far been supplied in Southern
Africa – to Vale for its Moatize coal mine in
Mozambique. Several smaller 6060 FS models
(with a 61-tonne capacity) have also been sold
