Remote controls are a common feature
for such equipment as self-erecting tower
cranes and trench compactors. It is not sur-
prising, therefore, to see the technology be-
ing introduced into hydraulic excavators.

are situations in which it is unsafe

The technique is being used in New Zealand,
where renovation work and demolition is still
taking place in Christchurch following the
devastating earthquake in February 2011.
There are a number of residential proper-

they are close to a cliff edge and the ground
is very unstable. The New Zealand demoli-
tion company, Protranz are, therefore, using
a Komatsu 270LE excavator equipped with a
Remote control is not new. A paper
called“New Capability for Remote Controlled Excavation”
written by the Deere & Co.
Unstable ground meant that remote
controlled Komatsu demolition exca-
vators was the ideal solution during
remedial work after the Christchurch,
